Topic: How much would it cost to build mining rig? - page 2. (Read 14436 times)

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

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.
