Topic: Part list help! (Read 1060 times)

I've gone with 8 1070s and 2 850w. They just arrived haven't put them together yet. Can't answer your question yet.

Did you order and the rig is up and running?

Do you have all psu connected to the motherboard? You were talking about 4 psu, but I thought the mb only needed 3?
Can the gpu draw power from the board or do you need powered risers? On the website it seems like enough to connect psu to mb.
Risers gets power from the psu AND gpu gets power from psu?

If you can get the Gaming for less than the SC, do it.
They're normally MORE expensive.

 Just double-check make sure it doesn't need additional power connectors that the SC doesn't need first.

Damn the one you are suggesting (08G-P4-5173-KR) is $560 but I can only get 2 at that price. The rest I have to get at $580

What about the 08G-P4-5171-KR EVGA GeForce GTX 1070 GAMING, 8GB GDDR5, ACX 3.0 & Black Edition? I can get that one for $553

I would recommend AGAINST those Gigabyte cards - they really went cheap on their fans on everything BUT the Aorus line the last couple-three years.
They work well enough as long as the fans are running though, and decent cooling, but I've had fans go out on *2* of them (1 fan each) in the last month, and the fans are deliberately designed to be a nightmare to try to re-lube (not that re-lubing lasts long in ANY case).

EVGA, MSI are all ball bearing fans (except PERHAPS the MSI blower models, I've not gotten confirmation there either way) - I'm fond of the EVGA SC "black" models for their consistantly good cooling, dual ball bearing fans, low level of fancy "pretty" LED lighting that just wastes money on the card design and construction, and usually low pricing.

OK ill order these cables that Vann has already suggested https://www.aliexpress.com/item/10Pcs-Set-Dual-Molex-4-Pin-To-One-PCI-E-6-Pin-Power-Connector-Y-Adapter/32820421116.html

Alright here is my buy list again. If there are no more suggestions or problems I will order it:

ASUS B250 MINING EXPERT
$181.99

DREVO X1 120GB 2.5 Inch SSD SATA III Internal Solid State Drive
$69.99
 
Ballistix Sport LT 4GB Single DDR4 RAM
$59.99

Intel Celeron G3900
$53.99

Gigabyte GV-N1070WF2OC-8GD Gtx 1070
8x $513.50

EVGA G2 850W
2x $176.9

PCIE Risers

Dual Molex to 6 Pin PCIE

PC power switch

The graphics cards won't be drawing from the PCIe Riser as long as you have the PCI-E connected directly to the video card.  My rigs run just fine on SATA power connectors directly to the Riser.
6 GTX 1070 + MB + CPU + RAM + SSD = 75 watts idle and 860 watts at full hashing load (cards set to 90% power).  I run that 860 load on a single 1000 watt PS

G3930 is cheaper by a couple bucks - but has Kaby Lake compatability issues with some motherboards and operating systems.
IMO it's worth the extra couple bucks to get an older Skylake part to avoid the issues.

 You cannot connect ANY risers safely to a SATA port - the actual SATA CONNECTOR is not rated for the 75 RATED WATTS POWER DRAW on the PCI-E bus (the CONNECTOR ITSELF is only rated 54, and some cards DRAW MORE from the PCI-E bus on peaks).
 Since you already have PCI-E risers, I'd recommend getting some MOLEX to PCI-E 6-pin adapters to use on most or all of them as the EVGA 850s aren't going to have any PCI-E connectors to spare.

With the 2 power supplies you will have plenty of sata power for those risers, you can do 3 risers per strand but I would recommend just doing 2 per stand, so use 2 cables off each PS to run 4 risers, and I would even chain the SSD off one of those.  Or if you are like I use 4 (120mm) fans to draw air away from the video cards, using a molex cable strand to power the fans and the SSD (via molex to sata adapter)

https://www.amazon.com/gp/product/B016VJ0F4Y - Fans that I use, quiet and move enough air

how many risers can I safely connect to one sata port. I heard if you connect too many they will fry the sata connectors.
here are my adapters: https://i.imgur.com/c0rsSEu.jpg
looking at the back of one g2 850w should I do this?:
PSU G2 850w #1https://i.imgur.com/xh3iz6M.jpg
PSU G2 850w #2https://i.imgur.com/RxcTphu.jpg

Yes, you only need a single sata for your SSD (64gb MFC is plenty) if you choose to use an SSD, some just boot off usb flash
The two 850s will each have about 8-12 SATA connectors, plenty to power the risers
CPU/MB/SSD/Risers will use 100-150 watts total

I can power 8 1070s, 8 risers, cpu, mobo, and ssd with two 850w g2 evga?
How should I safely power the risers? Split it all evenly?
I have 6 pin risers coming that come with 6pin - sata adapters.
Power the risers via the sata ports on the psu's?

Yes I'm using USD

Even the spread, you would run 5 less riser cards and the 675 Watts is going to save you >$2.50CAD/day ($912/year)

Plus you will save on the cost of the power supplies, not needing as large of wattage nor will you need 2 circuits.  The two 850s will run on a single 20 amp safely

are you giving me USD prices?
ive been posting in CAD.
The cheapest 1070 I can find is $534.9 (newegg.ca)
8 gtx1070 = $4280
13 rx570 = $3651

oh and good catch about those PSU's I didn't notice the 200v input thank you

ROG -STRIX-RX570-4G-GAMING  13 x $280.39 = $3,651
Hash Rate NeoScrypt is about 8,000 kH/s
TDP 150W (90% is 135W)

Asus GTX 1070  8 x $433 = $3,464
Hash Rate NeoScrypt is about 8,000 kH/s
TDP 150W (90% is 135W)

5 LESS cards will result in the same hashing power for $190 LESS!

You will also save 675 watts and have more room to add on later!

That 1800W power supply is NOT rated for 120V US power.....  It might work, might not!  You need about 1300 watts at 100% or 1180 watts at 90% card power.  
Two of these will suffice for $120/ea - https://www.newegg.com/Product/Product.aspx?Item=N82E16817151188

G3930 is cheaper - https://www.newegg.com/Product/Product.aspx?Item=N82E16819117748

wow, that is not easy at all

Ok here is my list, if everything looks good I'm gonna go ahead and order it

ASUS B250 MINING EXPERT
$181.99

DREVO X1 120GB 2.5 Inch SSD SATA III Internal Solid State Drive
$69.99
 
Ballistix Sport LT 4GB Single DDR4 RAM

So for these psu's they have 12 PCIE cables? Should I connect it something like this:

PSU # 1
atx
cpu
PCIE1 = gpu1
PCIE2 = riser 1
PCIE3 = riser 2
PCIE4 = riser 3
PCIE5 = riser 4
PCIE6 = riser 5
PCIE7 = riser 6
PCIE8 = riser 7
PCIE9 = riser 8
PCIE10 = riser 9
PCIE11 = riser 10 & 11 (splitter)
PCIE12 = riser 12 & 13 (splitter)

PSU # 2
PCIE1-6 = gpu2-7

PSU # 3
PCIE1-6 = gpu8-13

Corsair - is iffy, it depends on who is making a specific line for them as to if it's any good or not - and I've given up on trying to keep track of them, since their GOOD lines are mostly Seasonic made anyway (I think the do use SuperFlower for one of their good lines, like EVGA does for the G2).

 Thermaltake - I've not been impressed with ever on power supplies, though they make some good cases.

At your quoted prices, the 4GB 570 is probably the best option - it will be lower hashrate but close enough that the ROI on it should be somewhat faster, which is CRITICAL if you plan to mine ETH on them given the very "up in the air on when but being actively worked on" of ETH moving to Proof of Stake.

I already pulled the trigger on the pcie risers. They only have 6 pin on them but they come with a 6 pin to sata connector.

Ok I am definitely gonna grab the Asus board and 2 EVGA G2 1000w. Thank you.
What do you think of the Corsair HX Series HX1200 ($289.99) or Thermaltake PS-TPD-1200MPCGUS-1 ($232)? They are almost $100 cheaper than the EVGA SuperNOVA 1200 P2 ($369)

I am just not finding good prices on newegg.ca
I am gonna order mostly everything from www.pc-canada.com  they have discounts on bulk orders as well.

I am still not 100% sure on 570 vs 580
4gb 580 $325
8gb 580 $360
vs.
4gb 570 $284

 You CAN run them safely via MOLEX adapters - and there are some with all 3 connections that are the recent "4 cap" versions.
 The COBOC ones Newegg sells as an example, seen the same design from a few other places.

 You don't HAVE to run 19 cards from the ASUS B250 Mining Pro to make it worthwhile - the on-board power supply management is nice, and saves a few $$ + is simpler vs having to use Add2PS type adapters.
 If it's lower cost vs a 13-slot MB, it's DEFINITELY the better choice.

 NewEgg has a Canadian branch, can't hurt to check them in addition to the other sites you mention.

 I strongly recommend use of the EVGA G2 supply line over the G1 or the GQ or the G3 - the BALL BEARING fan is going to outlast the "fancy name sleeve bearing" junk in the other lines.
 I'm not 100% sure on the G2L line - I think it's also ball bearing fan, but the power connections are kinda wierd and do NOT match up with anything else at all.
 I can also recommend the Seasonic X-series, but those are in very short supply and getting way expensive when you CAN find them any more.

I can only find the Asrock H110 Pro BTC+ for $235.19
But I can find the Asus B250 mining expert  for $181.99
Should I just get the Asus an just run 13 amd cards off it? Would Asrock be more stable?


How much do 580 consume dual mining?
I am definitely gonna overclock and undervolt them
The lowest I see is MSI 4gb 580 for $325
and Asus 570 are around $284

Is it worth it to go for 580's?
I can only find mining reviews on the 8gb versions of the 580's.
The 8gb 580's start at $359.99
That ruins my ROI.

I was looking into distributors yesterday
I did find a few for Canada, I am gonna try to get an account with one of them and get a quote for the 580's.

Anyways I was thinking of running the Linux based OS's
is there any benefit of running windows?

The problem is not Windows. The problem is the Asus B250 mining expert REQUIRES using Nvidia P106 mining cards with more than 13 cards on the board. BBT was able to run 21 cards, 13 AMD RX 570 and 8 Nvidia P106 in Windows 10 with the latest Crimson Relive drivers on the Asus B250 mining expert. I don't think anyone has been able to run more than 13 AMD cards in Linux on this board either.

For the power supplies, I'd recommend getting 3 of these:
https://www.aliexpress.com/item/New-and-original-Gold-POWER-1800W-BTC-power-supply-for-R9-380-RX-470-RX480-6/32825827647.html?spm=a2g0s.9042311.0.0.xNt9Ym
Im running a mining farm with 48 of these PSUs for the past 8 months, and none of them have failed, you get ample power, and running 6 cards on each.

1x 570 consumes around 100W from the wall mining ethereum solo, and 140W from the wall dual mining.
Even thought those are average numbers, in any electrical components, there will almost always be that power surge that occurs for a split second; you do not want your PSU to blow up because of that. Thats why I'd always recommend anyone to calculate their power requirements to be at 80% of the PSUs capacity; so if you have a 1000W PSU, try to calculate that your components connected to the PSU to run at 800W, and leave that extra room for electrical surges.

18 cards will not run on Windows as of now, we are expecting an update in december that will allow windows to recognize 18 cards; where currently linux is the only way to go for more than 12 GPU. (Simplemining OS is a nice noob friendly linux OS for miners)

With the asus motherboard, you do not need the dual/triple PSU cables. You may hook 3 PSUs to the motherboard, and it does the job on its own.

The graphic cards are too expensive, even with canada's inflated prices.
A quick check on newegg.ca , I was able to build a cart of 18 RX580s, but different vendors, that can easily save you 500$ and If I were you, I'd configure each card's overclock/undervolt through their bios (time consuming, but worth the effort).
Prices are inflated as well in my country's local market (Dubai, UAE), but what I've done is I found the distributor's for these graphic cards in my country, and Im purchasing directly from them. In my case it was sapphire.

I would recommend getting a bigger harddrive, or at least a second cheap non-SSD drive for virtual memory. I had this issue before when I upgraded my rigs from 6gpus each to 12 gpu where claymore's cryptonote miner (cryptonight) requires to have at least the same amount of VRAM as virtual memory. In your case, it would be 18x 4GB which is 72GB + your OS which is around 20GB; a 120gb SSD would be a better option, and it isnt that much more expensive.

7 RX 570 dual mining will use ~700 W from the VGA power only. You can run 7 cards on one 900 W and 6 on the other one. Keep in mind server PSU's are made to run in a server room where no one is around them and without consideration to how loud the fans are. At 80% power, the PSU fans will be spinning fast and most likely loud. You also will have to turn the server PSU's on and off manually since you don't have an ATX 24-pin to daisy chain them. For the motherboard and 13 risers I would recommend a 1000 W ATX PSU minimum.

Wow those are cheap.
So 2 HP 900w@110v
What size evga psu should I get?

Get a server power supply plus breakout board and a couple 6pin male to 8pin male cables in addition to a desktop psu.  I have some hp's that will do 900w at 110v.  That's the cheapest way to power it. 

There are sata and 4-pin molex risers, but I like 6-pin PCI-E risers the best. They have better power regulation with four capacitors instead of three, a voltage regulator to prevent spikes and 6-pin connectors that are rated for 75W each. If you use sata or molex risers, be sure to only connect 2 risers max per psu strand or you will overload the connector and cable. Sometines I use dual 4-pin molex to 6-pin PCI-E adapter cables to power risers but the quality of the connectors is not the best.

https://www.aliexpress.com/item/10Pcs-Set-Dual-Molex-4-Pin-To-One-PCI-E-6-Pin-Power-Connector-Y-Adapter/32820421116.html?

Wow thanks alot for that and everything. That has clarified alot for me. I didn't realize you have to run risers off the PCIe ports on PSUs.

You don't want to run PSU's close to the rated the capacity. They won't be as efficient and it will shorten it's lifespan. 50% to 80% of the rated capacity is where PSU will run most efficiently and cool. The other consideration is how many PCI-E connecors you need for all the GPU's and risers. Many PSU's less than 1000W will only have 4 PCI-E connectors per PSU. For 13  RX 570's you will need a minmum of 13 individual 8-pin connectors just for the VGA power. Some cards like the Nitro+ also have a 6-pin connector that may be optional. For risers I use 6-pin PCI-E risers only and connect two or three risers per PSU 8-pin cable using a PCI-E 8-pin to dual 6+2 splitter cable, figure another 5 PCI-E PSU ports for the risers, so in total you need a minimum of 18 PCI-E ports.

For that you can use a minimum of 1 x 1200 W EVGA G2/P2 PSU for the motherboard, risers and 1 VGA together with 2 x EVGA 1000 W G2/P2 for the rest of the VGA power with a triple ATX PSU splitter cable, or a server PSU with enough PCI-E connectors like the one I mentioned above and a EVGA G2/P2 1000 W for the motherboard, using the PCI-E connectors for the risers only.

You are running 2475w at the wall
and have 3450w worth of psu's.

If I were to run 13 570's can I get away with 3 850w? Or 1 1000w and 2 850w?

Mostly RX 480/580 8GB cards. Asus STRIX, Sapphire Nitro+ and  MSI Gaming X. Also a Saphire Pulse RX 580 4 GB and a Nitro+ RX 570 4GB with a EVGA 1600 W T2 for the motherboard, all 13 risers and 4 cards VGA power on a 120V 20A outlet together with a EVGA P2 1000 W + G2 850 W for the rest of the cards on a 15A circuit. All the cards have a Polaris Bios Editor v1.62 'one click timing patch' Bios mod and I get the best result with the Sapphire Nitro+ RX 580's 30-30.5 MH/s ETH 875 MH/s DCR dual mining.

What mixed cards are you running?
Also what wall circuits are you running that into?

I have one 120v 20amp curcuit and one 120v 15amp circuit running to one room.

I wouldn't hold my breath waiting for Asus to release a firmware update. Dual mining ETH + DCR a RX 570 will pull ~140 W between the GPU and riser and a RX 580 ~180 W. I have a 13 card mixed card build on a H110 Pro BTC+ dual mining ETH + DCR and it's been rock solid. Total power draw at the wall is 2475 W with a triple ATX PSU setup.



I was running it off of a dual 120V 2400W PSU I ordered from a manufacturer on Alibaba and a 1000 W ATX for the motherboard and risers. The dual 120V 2400 W PSU has 18 PCI-E 6+2 connectors that I use for the GPU VGA power inputs. Total cost through PayPal was $181 and shipping via DHL direct from the manufacturer was very quick.

http://www.panto-tech.com/products/206-110v-260v-power-supply-2400W-for-miner.html

For a while it ran quiet at less than 50% of the capacity. When you run it at more than that, the fans got progressively louder the more wattage you pull from it. Recently the fans started running louder and it became annoying to deal with the constant high pitched whining sound. I got tired of dealing with the noise and switched to a triple ATX PSU setup with a triple ATX power adapter cable.

https://www.aliexpress.com/item/New-24-Pin-20-4Pin-Triple-PSU-ATX-Power-Supply-Adapter-Cable-18AWG-Wire-For-Mining/32827769189.html?

The same manufacturer also has the same PSU with only the 18 PCI-E connectors and it's about $30 less, so I think that may be a better option for a dual PSU setup since I don't use the ATX 24-pin or sata/molex connectors on it.

http://www.panto-tech.com/products/207-110v-220v-power-supply-2400W-for-miner.html

This is the same PSU BBT used in his 21 card build on the Asus B250 mining expert live stream and you can hear how loud it is.

https://www.youtube.com/watch?v=miUoqnUqk9M&feature=youtu.be&t=6201

IDK, I'm running a 480 and 3 570s off a 750w PSU.  You have to undervolt them.  Bits be trippin put out a good video on how to mod a 570.  Go to youtube and check it out.

Ya you guys are convincing me to do just 12 card builds on ASRock H110 Pro BTC+.

Does the RX570 draw the same in dual mining?

With 190w per card I wouldn't even get away with 4 gpus on a 750w.
Should I do 4 cards per 850w $140
Or just 3 cards per 650w for $100

I guess that saves me $20 if I go 650w and only use 12 GPUS

Crap, I misunderstood Asus's marketing speak. Thanks for clarifying that for me.
Do you know if Asus planned firmware update for Q4 2017 will support all 19 or 18 cards of amd?

I'll go with Vann's advice, even you manage all cards to be working on one Rig this is not practical for since it has a centralized failure, mining is not a 100% reliable all the time of the day, if any of the GPU's, PC components, Softwares or even connectivity failed, your profits will greatly reduced.

Also, each RX470 will draw 180-190w  in dual mining, 4x650w PSU in 18GPU is not sufficient to power them all

You won't be able to run all 18 cards on the same motherboard. Running more than 13 GPU's with the Asus B250 mining expert REQUIRES using Nvidia P106 mining cards.

https://bitcointalksearch.org/topic/m.24031325

If you want to run all AMD cards I would suggest breaking it up in to a 12 card build on a ASRock H110 Pro BTC+ and a 6 card build on a Biostar TB85 or another H110 Pro BTC+ motherboard if you plan to expand.

Hey everyone, I would love it if someone could check over my part list and give me some opinions.
I am not 100% sure on my PSU selection. I've used PSU calculators to try and figure it out on my own but I am not sure how much the molex on the mobo and risers draw.

On the ASUS B250 MINING EXPERT do I populate all 3 ATX and bridge the forth PSU with another? What about the 3 molex connections on the board itself?

I live in Canada, we don't have good availability or prices like the states. All my prices are in CAD.
