Topic: How much would it cost to build mining rig? (Read 14436 times)

Seriously, is this for real? i suggest you take a look when that post has been made. A lot of things have changed in these years. It's not all about mine bitcoin but altcoin is much better to consider it has less difficulty rather than bitcoin. Dude, that equipment already out of dated and i prefer to get used 1070ti or waiting for NAVI if that specification built on this time.

Forget many altcoins as well - scrypt coins like Litecoin have been ASIC-dominated for a few YEARS now in particular and the widespread proliferation of ASIC for many algorithms over the last year has killed GPU mining for a LOT of algorithms/coins where GPUs used to be highly profitable.
Mining rigs don't need a ton of ram - 16GB is definitely overkill even for an ETH rig that is using the old-type "build the DAG file on the CPU" type miners, though it MIGHT need 8 - and any other GPU-mineable algorithm isn't going to need 8.

That was a great suggestion, however, as per my understanding, this equipment is not good enough to mine Bitcoin, but it can be a good option for altcoins like Litecoin. Also, I think the RAM should be 8 or 16 GB.

You need to start from somewhere, with 2k dollars miner you can`t mine bitcoin, you will need to start with some coin that is still at low mining difficulty, how difficulty rises you will need to upgrade you miners, it`s a never ending game in my opinion. But you need to start somewhere, today it`s not about miners I think, you need to find good coin to start, that`s far more important.

 It always seemed to me that the amount should be around 10K$ , so you can feel a little bit like a miner, and it turns out that 2K can be enough.

$ 2000 a good ferm to stir. Of the six GTX1070 will be a normal modern small farm. And you can still for RX580 to do, but they are stronger bask

rather than building it from scratch, it's better to buy it directly. I think nowadays enough people sell in an already built-up situation. which might cost $ 2500 to $ 3000. however, you have to choose the right place for that.

I think with the ever-increasing computational complexity - all you can get is new coins, and the payback from such a station will be quite long.

It`s a good idea if he is hardware specialist or have an opportunity to get such a specialist. But if he is a newbie - he can get terrible rig several times more expensive that it costs. On ebay maybe, but you are buying smth that you havent tested.
I bought several used rigs for myself at past year - they are nice and cheap.

You can find a lot of good condition used mining hardware on second hand markets.  I think it is much smarter to buy used instead of buying new.  You also get buyer protection if you are buying on ebay so even if something breaks within 30 days you can still get a refund.

It would cost as much as the specs you desire to put into it. Also you would have to consider what type of coins you would like to mine, as AMD and NVIDIA are different with different algorithm's.

I think it is not good to buy the second-hand Mining Rigs because their life will be very less, mostly it will consume more power and don't have feature as the new ones. So it is always good to buy the new one even though it cost the high value. For the old one, the mining rigs will get overheating in a short period of time.

Roughly, yes. Buuut...depends if you buy 2nd hand or new GPU's, and of course which model you pick. This decision depends on what algos you plan to mine, and also your electric rates (for example, RX470s are OK on ETH, but expensive to run if your electric is high).

Basically a 'gpu rig' can be anything from a 2nd hand bunch of chinese fake gpus and a clone psu nailed to some wood, through to a professional grounded setup with server psus/EVGA ATX and brand new premium GPUS. Obviously the cost is very different, as will the potential revenue. It's a bit like asking how much a 'car' costs, and how fast it goes...

In the first page, the answer is 2k $. Is this same in current conditions and what about profitability? Any expert?

That depends on how much your budget and rather than putting about how much cost and this will not accurate. You can assume if you have x amounts and wanna build a mining rig and that will be a reasonable question rather than talk about how much consume to buy a mining rigs in 2019.
How much your budget?

I agree with him. There are lots of second hand mining rigs available used for 2-3 months, since people stopped mining because of low profitability. Or try to find second hand gpu's from gamers.

Second hand mining rigs are now available at much cheaper rates when compared to the new ones, and depending on your limited funding, this may be the best option for you. But always remember that the old rigs can be more power-consuming, more prone to over-heating and most importantly they can have a significantly shorter lifespan.

Video cards 1070 can consume up to 240w. For 6 cards and for the rest of the system components, you will need a power supply of at least 2000w to reach their full potential. I think that for your mining rig you can easily find a good power supply no more than $250.

How much would it cost with listed items to build mining rig in 2019

thanks

im building and selling rigs on my spare time. Last one i have sold was: (3500 euro or ~4200 USD)
*Biostar TB250-BTC+ motherboard
*Processor Intel G4400
*4GB DDR4 RAM
*120GB Kingston SSD
*8 units  - Sapphire Nitro+ Special Edition Radeon RX 580 8GB DDR5 + Riser v008
*2 units  - Fully modular Corsair HX850, 80 PLUS platinium PSU
*Aluminium frame (custom made)

The HX line from Corsair was the best before AX came along. I see a lot of 860AX that have shitty reviews e.g. newegg.
I think the HX line was the best I remember buying a 620HX for 150$ back in 2008. How times have changed.
Btw that PSU is in my mining rig to this day and is powering a 1070

For a 6x 1060s easily do 2 psu's 750 p2, g2 and save yourself a few hundred dollars. 1600 P2 for that setup is overkill.

Yes, I was planning on using Linux.

Are u going to use Linux or are you going to try it on WIn 10?

I was planning on scaling to 12 GPUs.  The motherboard I bought can hold 19 GPUs and has 3 separate power supplies per 6 GPUs.  I was planning on getting 2 power supplies eventually. 

 The ONLY Corsair line I will even look at is the AX - the rest all use CHEAP JUNK "fancy name" sleeve bearing fans that do not last at high loads.
 The AX line happens to be basically the old Seasonic SS-series Platinum rated power supplies with some very minor changes (same platform as the Seasonic X-series Gold supplies).

 EVGA G2/P2/T2 line is good, but I don't know if they still make them.
 Their newer G3/P3/T3 line has those junk "fancy name" sleeve bearing fans, I won't even LOOK at the things.
 EVGA GQ line uses junk "fancy name" sleeve bearing fans.


 The H81 Pro works well, but it's Socket 1150 which is getting hard to find decent low-cost CPUs for.
 I have no idea what they changed on the "rev 2" of that board vs the original, but since the original is long out of production it doesn't matter much any more if you don't already HAVE the original.
 I think they make a H110-based update to that board that is socket 1151 and otherwise pretty much the same.


 The GTX 1080 isn't a real good mining choice - it's not BAD, but it gets beat on efficiency by the 1070ti on NVidia-friendly coins and the 1070 beats it hands down on ETH - not that the 1070 should be mining ETH anyway, it makes more on other stuff.
 1080 isn't a BAD choice - just not optimal on hash/$ or hash/watt though close vs the other NVidia options.

 AMD high-end Polaris cards do well on Ethash coins (ETH/ETC/related), fair on Cryoptonight (Monero), and tend to not be all that good on much of anything else (probably some small niche coins they do well I don't know about though) though not BAD, just not optimal....

Are these GPU's still profitable compared to 1070 or 1080's?

I also don't agree with your Psu or gpu advice.  Not saying it's bad but I have a different opinion.  If mining Eth why 5x 580s for 310 dollars? I'd rather have 8x 570s at 210 dollars.  Those should be good for another year, and who knows if mining Eth will still be one of the more profitable coins in a year?  8 570s will get you about 224 mHs vs 150 MHs for those 5 580s.

I'd also rather mine Eth with 1070s if I have to pay over 300 dollars for the 580s anyways and wanted DAG size insuranceil into 2019.

I would also get 2 PSUs.  750s or 850 And I'd go evga gq.   It's close in price and you run much more efficiently at 50 to 60 percent of load and allows you to run 8 cards.

Don't buy off eBay either.  They are selling stuff above retail price and you don't get the warranty.

Depends on what you are gonna buy for 2.5k
https://www.ebay.com/itm/XFX-AMD-Radeon-RX-580-GTR-S-Black-Edition-8GB-GDDR5-SDRAM-PCI-Express-3-0-x16-V/173046770298?hash=item284a642a7a:g:zfkAAOSwEEBaPWka

theres one problem with your "but going forward people getting into the game are going to need to learn to optimize, optimize, optimize."

garenteed that's going to be too much for a beginner to handle and not to mention ANY BIOS MODS VOID THE FUCKING WARRENTY, which might I add YOU DIDNT MENTION. come on man. how would you like to be told only a part of the information then only to find out the gpu someone else told you to mod got screwed and they failed to say hey if you mod the bios it will void the warrenty and you wont be able to get a replacement unless you can manage to get the original bios back on it and also considering most gpus currently only come with a single bios telling a noob to mod his stuff is in fact a bad idea all in itself.

How much can you earn monthly with a 2 - 2.5k rig?

Thanks everyone!  I now feel more confident in my power supply purchase. 

I'm running 6 x 1070 and 7 x 1070/1070TI rigs on Corsair HX1200i PSU with no problems.

If you run your cards at around 125w, it would be 6x125=750 + lets say 100w system =850w.
850/1200=70% load on PSU, so there's room for another card.

HX1200i (platinum) should be under $300.
Also, get 1070TIs instead of regular 1070s  : )

850 PSU is enough for the 3 cards are something but if you want to extend the multiple graphics card in the mining board you will get the 1200 power supply means you will get the better supply for mining rig. You can build the mining rig with the 12 cards with the double step rig.
Cards are according to the cost you spare for it. Most preferable mining card is rx 470 8GB cards or nividia 1070ti cards. Choose the card according to the amount you invested.

Looking at the prices and depending n where you live you could probably get a 4gpu rig $700 for the Mobo ram cpu psu and HDD and the rest for the cards.


That is why overkill unless you plan on adding more gpus into the 6 you rig. A 1200w platinum PSU is good. Evga or cosair.

Depends. Are you planning to mine for longer than 6months? Then go for the quality PSUs. EVGA is good and so is Corsair.

Can't go wrong with those - they are pricey but those and G2 850's are my 2 top favorite PSU's. I also have Thermaltake 1500, Quark 850's and Corsair 850's, all of them have been hashing away for the past year no issues so far but who knows down the line.

Power supplies bear a pretty heavy load so I wouldn't go cheap on those. I don't really have a recommendation because I'm currently mid build myself but articles I've read say to get quality power supplies.

How much should I spend on a power supply?  I am building a rig with 6 1070s and was thinking of buying a EVGA SuperNOVA 1600 P2 80+ PLATINUM.  Any advice is appreciated.

The 580 price has reduced from that figure.

it depend if you want a cheap amd rig you can do it with $1000 i think if you buy used gpu with nvidia $2k is necessary or even 3k depend on the brand

If you go to Microcenter its not just the prices.  Read the warranty they offer.  If you return a card they will give you the value of the card on a gift card:

Micro Center Replacement Protection Plan*
If your merchandise breaks or fails, the Micro Center Replacement Plan will go to work for you. Just bring your covered merchandise in to Micro Center for an assessment of the situation. If a replacement is needed, we'll provide you with a Gift Card to use at your local Micro Center store. Use the gift card to purchase a replacement, upgrade to a different model, or buy something else. It's your choice!

Its a deal you can't beat.  They aren't testing the returns while you wait...obviously...Artifacts, fans, dead card, anything...take it back and you will get a giftcard - the cost of the warranty (about 20-30.00)

In your list you can save about $ 150 if you buy RX 580 4Gb. The rate of extraction will remain the same and the savings is approximately 10% of the cost of the GPU. You can buy a second hand motherboard with support for 4 GPU. A few of these cards will cost less than one with support 6 GPU. The same situation with power supplies. With the current profitability of mining coins need any saving.

lol ya know out of everything that has been told to the OP, NOT one of you happened to mention that putting a modded bios voids the warranty with most/all gpu manufactures, with that said do you really think a newbie should be modding his gpus without the proper information, no that's just a horrible idea why would you tell someone that, not to mention if a gpu dies with the modded bios on there, the dude would freak out not everyone knows how to put the original bios back on there once the gpu has done died have you ever herd of KISS - keep it simple stupid, newbies to start with need it simple they don't need a bunch of extra crap thrown at them just to confuse them more

build yourself an open air case or find one of those shoe racks for $11 dollars at walmart and take the fans from the case and install them on to the open air case, I wouldnt keep them enclosed but I haven't ran 1060s so im not sure how hot they get

Thanks!  I actually just dug out my old gaming rig that the motherboard fried on a few years back. Turns out it still has a good 850w power supply, DDR 3, and an older i3 or i5 processor. The case has plenty of fans and is capable of holding 4 cards.  Seems like all i need to do is add a new hard drive, motherboard and 3x 1060s.

Kinda excited now that I just cut my cost down a bit.

IMO there is no point to using a high-end Ryzen or high-end Intel CPU in a mining rig - yes, you CAN make a little back on them mining Monero but the PAYOFF is measured in years, as opposed to putting a cheap G-series Intel or using a FX-series or even a A-series AMD base instead.

 FX series CPUs in particular are ballpark $100 ($130ish for the high-end FX 8xxx series) vs *$300* ballpark for a Ryzen 1700 and MORE for that high-end Intel you listed, and the 8320E in particular is good for around 300-350 hash/sec on Monero (vs 400ish for the Ryzen 1700 and perhaps as high as 500 for the 1800x or that Intel).

 AM3+ motherboards also tend to be lower cost than AM4 at this point for similar capabilities (though no M2 on a lot of them, but M2 is a WASTE on a mining machine instead of using a much cheaper HD or USB key option), as are FM2+ motherboards.

 Recent price bouncing in the RAM market has also dropped DDR3 back to being cheaper than the same capacity of DDR4 (though it's still pretty close).


 The one down side is that AM3+ and FM2+ motherboards are starting to become less available, as some manufacturers have stopped making some models in favor of AM4 and whatever that slot the Threadripper uses (SM4? Can't remember offhand) based motherboards.

Strange of course the question. Looking at what cards you want to build a rig, what power. Or do you need a minimum price tag?

you sir have made my day. I live close by one as well now I need to evaluate my options on some systems to buy. I have alot of options available it seems

Thinking between the two as an initial investment, which provides the best opportunities for adding a card or two in the future?  Seems like the first one may be better, cheaper and better power supply.

Cost- $1199

AMD Ryzen 7 1700 8-Core Processor 3.0GHz
Motherboard Chipset AMD B350
NVIDIA GeForce GTX 1070 8GB
16GB DDR4 RAM
1TB HDD + 240GB SS
Power Supply 700 Watt

Or

Cost- $1299

Intel Core i7-7700K Processor 4.2GHz
NVIDIA GeForce GTX 1070 8GB GDDR5 VR Ready
16GB DDR4-2400 RAM
512GB M.2 SSD
Motherboard Chipset Intel Z270
Power Supply- 500 Watt


All help is appreciated in this adventure and if someone can chat 1 on 1 and help a fellow new miner out it would be greatly appreciated.

I am also riding the 1070 bandwagon. I put a 7 card rig together for 3900usd. As you guessed correctly I live on the other side of the pond. Prices are higher but I was fairly inexperienced when I got into it.

Asus z270-a
Intel G3430
4gb ram
120gb m.2 SSD
7x zotac 1070 mini
2x EVGA 750W gold PSU
7x pci-e powered usb risers

Is it the best setup for the money? Probably not. Is it making a lot of money with 6 months ROI? Definitely not. Am I happy with it? Yes. I think so? I wouldn't get a 1060 or a 1050ti but get what you think will make money! Let's hope you get something together that works for you!

Micro Center is lucky they don't have a store in or near Central Washington - it would NEVER have any stock of AMD RX 470/480/570/580 cards for more than a few hours at those prices.

hi.
who is mining now?
how profitable is it?

Lets try simple calculations for Intel Platform:
1. MoBo: MSI Z270 A-Pro - 100$ (support up to 7GPUs)
2. CPU: Pentium G4400 - 55$
3. RAM: DDR4 8Gb - 70$
4. SSD: 60Gb - 50$
5. USB Risers: 6-7$, for 6 risers - 36-42$
6. m.2 to PCI-e adapter: 2-4$
SUM: 320$

It remains: 1680$ for GPUs and PSU. GPUs and PSU are interdependent variables. GTX1070 or GTX1080 would be the best choise in the beggining. I recommend choose GPUs with 3-slot cooling system. So for remaining sum you can buy 2 GPUs and good PSU (one or two) with Gold plus sertificate at least. And do not forget about case (handmade is practically one choise) and external fans for additional cooling of GPUs.

So with this TYPICAL 2000$  config
Typical ETH build:

5 x RX580 8 GB - $310 ea or $1,550 total
1 x mobo with support for 5 or 6 GPUs - ~$120
1 x CPU (Intel G4400) - ~$50
1 x RAM 4 GB - ~ $30
1 x 120 GB SSD - ~$50
5 x PCIe USB risers - $50
1 x 1000 watts PSU - $150
,

nowadays, How much $ we can make monthly ?

GTX 1060 6way mining rig has price of almost $2000.

RX480 card real power usage during mining , compare software reading vs real life power draw

As everyone posted, it depends.  I am one of the more fortunate people, I live by a Micro Center http://www.microcenter.com/search/search_results.aspx?Ntt=Radeon+RX+570.  I can drive down the street and get a 570 for 219, I can get a 580 for 224, they have open box items at a steep discount and full warranty.  Most of the time, I can get things brand new cheaper than you can find it on ebay. 

Not only are they the cheapest retail store (pretty much in the world), they have the best warranty (in the world).  If you buy their warranty and say a fan dies, they take it back and give you store credit, no need to worry about RMA or the like.

Your mileage may vary....

What you see in the afterburner app or gpuz ,that is not your vga card power consumption ! That is how much power your GPU using on the graphics card !  
So if your gpuz reading is 135 watts , that card easy can pull anywhere from 150 to 250 watts  , if you did not properly undervolted/underclocked fine tuned your cards. This is sometimes really hard for newbies

Rig price will all depend on how much you are willing to invest and maybe even lose if it does not work out if you want top end gpu it going to cost you coupled with how many of them you going to run. Lucky there is a good collection of knowledge on bitcointalk.org. Reading topics and YouTube will point you in the right direction too.

I get the OP's enthusiasm about doing something he haven't done before with the promises of golden pastures of raking in coins that only increases in value. But this route isn't usually trodden by newbies and people who doesn't have any idea how pc hardware work.

This isn't just about mining, but building a working computer from spare parts you buy separately. We can suggest everything we know which to buy, what brand to look for at what price, but if the guy doesn't even know how to install windows, or why LGA1151 motherboards won't take AMD CPUs we're already dead in the water here.

Now, assuming he does know something about computer building, all the previous posts are helpful and should give him a bit of an idea what to buy. I'm also against buying a 1000w PSU to power 5 cards as being a noob, he wouldn't know right away how to undervolt his cards and lower the core clocks to run the cards cooler. This would mean he'll mine a few weeks of full-powered cards with high temps that will suck a lot of power, which will be evident right away in his power bill. God help him if he pays more than $0.10 per kWh.

Believe me, even if it's me, if I can run the miner and start mining, i'll worry about undervolting and optimizing later on. Who wants to be farther behind right?

And then when issues come along, troubleshooting will be another pain. It is and will always be.

 Easily will get you a viable 3-card GTX 1080 non-riser rig, possibly 4-5 card on a RX 470/570/480/580 or GTX 1060 based riser rig.

Yeah every little bit helps nowadays. I do agree with you, what is the point buying a 1300w for 5 or 6 gpu's, okay it will give you like 1 or 2% in efficiency in the long term but that will take 20 years for those 1 or 2% to return to you as money.

I have SEVERAL rigs of 7 x Rx 570's running at ~115W Dual mining, for a total system draw of about 850W on 1000W platinum PSU's so ... I agree with Za1n, if your'e getting into mining, you need to learn how to optimize, or you stay away.

+1 for 1060. Easy 24-25 on Ethash without song and dance. As for PSU I prefer to use server psu because it  needs to run 24/7 non stop

PICO adapter for MOBO and everything is a OK (also, risers with 6-pin pcie for straight connection from PSU)!
http://www.parallelminer.com/product-category/power-supply-kit/

The PSU should be a EVGA or CORSAIR 1200 watt , fully modular and Platinum rated like the Hx1200 from Corsair, this PSU can keep up 5 cards even if they are running near 200 watt but that is not the case because when you are mining Ethereum they are consuming 135 watt each from GPU-Z or MSI afterburner app.

I would advise you to buy 6x 1060 GB 3GB for 1200 USD which would be a better choice, the consumption would be much lower than with RX 580 and you can mine Zcash to get approximately the same amount as for 5x RX 580. Make sure to buy a good motherboard for mining, like ASROCK H81 PRO BTC which supports 6 cards easily.

The key is as you said as i said is : " properly tuned meaning under-volt mod applied with clocks and voltages properly adjusted"

So do you think when someone asking a question like : "I dont have the slightest idea how will i build one " , that person know how to properly tune  , mod the cards ? 

PLease ! dont give bad advice for newbies who dont have "slightest idea how he need to build ",  they can burn down they house !

I am not against overbuying on a quality PSU, well I am to a point, but linking some benchmark showing some extreme wattage usage does not help a beginner in any way and that was the main point to my rebuttal. Also, I think if you are getting into mining you do need to also learn how to tweak and optimize your rigs. Just throwing an overpriced excessive wattage PSU at non-optimized settings may have worked in April, May, June, July, and perhaps August for ROI purposes, but going forward people getting into the game are going to need to learn to optimize, optimize, optimize.

As far as the ROI question, I am with you 100% but I am tired of pointing out the obvious to people who only want to know how to get into mining. So I stopped pointing that fact out and now just offer advice on how to build rigs. But this again empathizes my goal of not overspending where you do not need to. Spending an extra $50-$75 on a oversized PSU will only lengthen that period.

So I recommend to the OP once he buys his gear, which I stand behind in my listing above, that he also comes back and asks about how to tweak it for optimal performance. There is also no harm in buying the base components that will support a a 5-6 GPU rig and only starting with 3-4 GPUs to learn these intricacies. Once you have this down you can always upgrade your rig to its maximum potential. This way you will have the best of both worlds, a reasonably priced and sized rig and you wont burn your house down in the interim period of learning how it all goes together and works.

He is not entirely wrong or right, I guess his reply was cause op is inexperienced so he will never hit the consumption you would hit. I do have experience and I can say 1000w is more than enough but you need skill to optimize it. Also the prices you said are spot on, around 2100 usd, 5 x rx 580  will give you around $4 per day which in turn you will get back your money back in 525 days or 18 months to be precise but your system will have to be 24/7 and without problems and that is impossible, so count it as 24 months to get your money back. If you buy eth right now, in few days you will get 500% or more hehe and no problems at all.

But you need to do some modification on the server PSU.

For a PSU I'd recommend getting a server one (94%eff. Platinum rated). ParallelMiner sells some really nice kits.

For a simple single rig with 6-8grfx cards to mine say.. vertcoin.. i recon about ~$1000 or less

Only worth it if you have cheap leccy and would take a while to earn back you initial investment, but eventually you'd be in profit.

Very bad advice on the psu ... dont try to build a 5-6 RX580-8GB rigs with a 1000 watts rated psu !!!
rx480/580 cards in some stress test can pull  over 200 watts easy during mining , mining with those cards are a real stress test / torture, with proper overclocking / undervolting the GPU/Mem you can reduce the wattage what those cards pull at the wall , but without any fine tune , those cards can pull over 200 watts each during mining!

[/quote]

While I reccomend having a bigger PSU as possible for spare room and extra connectors, no fucking polaris card should eat 200W, Not even dual-mining. Also mining eth is in no way a torture/stress for the gpu, that's just plain wrong.

I'd recomend to the OP to always watch for the number of PCI-e connectors his PSU has, some brand fuck up on this chpter(looking at you Super-Flower).

Th only bad advice around here is yours. I have personal experience with many such builds and you can run 5 or even 6 RX580s off a 1000 watt PSU easily. If you are pulling over 200 watts per card you are definitely doing it wrong, and those benchmarks you linked are showing extreme cases, which again if you are running your mining rig like this you are doing it wrong. The guy is asking advice on how to build a rig right and mindlessly telling him to buy a larger PSU than he needs because you link some extreme un-optimized use case benchmark is foolish, especially when the price starts to rapidly climb past the 1000 watts range.

A RX 580 properly tuned meaning under-volt mod applied with clocks and voltages properly adjusted will draw 130 watts when mining ETH only and ~150 watts if dual mining. So for ETH only we could do 5 x 130 = 650 Watts, dual mining it would be 5 x 150 or 750 watts, well within reason. Even if he went 6 GPUs (which I only speced 5 for the AMD RX 580, the 6 was for Nvidia 1060's) it would be 780 and 900 watts respectively. While a 6 x RX580 dual mining configuration might be starting to push the PSU, it is still well under the maximum. However, a 6x RX580 just ETH only would be well within reason at 780 watts, or under the 80% load guideline I like to run around.

With Nvidia, the 1060's run under 100 watts each when mining ETH alone, so that would be 600 watts with 6 cards. And for his budget he could get 3 1070's which might be around 200 watts each, so again 600 watts. So tell me again where is the bad advice?

Very bad advice on the psu ... dont try to build a 5-6 RX580-8GB rigs with a 1000 watts rated psu !!!
rx480/580 cards in some stress test can pull  over 200 watts easy during mining , mining with those cards are a real stress test / torture, with proper overclocking / undervolting the GPU/Mem you can reduce the wattage what those cards pull at the wall , but without any fine tune , those cards can pull over 200 watts each during mining!

Yes, $2000 is probably about the average investment in mining equipment. With that amount you could build a nice rig of 4 to 6 cards and the associated support hardware. Much of the choice will come down to which coins you want to mine. Ethereum typically favors AMD and Equihash (Zcash) favors Nvidia, but they both can mine the other algorithm in a pinch.

Typical ETH build:

5 x RX580 8 GB - $310 ea or $1,550 total
1 x mobo with support for 5 or 6 GPUs - ~$120
1 x CPU (Intel G4400) - ~$50
1 x RAM 4 GB - ~ $30
1 x 120 GB SSD - ~$50
5 x PCIe USB risers - $50
1 x 1000 watts PSU - $150

This would put you right at your $2,000 budget. You would also need some type of frame to hold everything so you might need another $50 or so in materials.

A Zcash (Equihash) build would be much the same except you would pick some Nvidia cards such as the 1070's or perhaps the 1060's instead. The 1070's run around $500 so you could run 3 x of them and the 1060's go for $200 for the 3 GB version and $350 for the 6 GB version so you could run 5 or even 6x (if your motherboard supports it).

pardon. Whar do you mean open end? Pls specify your answer.

how much it would cost? simple answer = open end

Hi bitcointalk, I want to build mining rig but I dont have the slightest idea how will i build one and how much would it cost me. Currently I have $ 2000. Would it suffice to build mining rig?
