Title: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: mewhoyou on May 22, 2017, 02:43:59 PM Going to start building my first 8 gpu rig..
Celeron 4gb Ram x 1 120gb SDD Gigabyte RX570 x 8 Riser x 10 Any recommendation on the PSU? will 1300 Gold fit the job?

Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: maleemk on May 22, 2017, 04:41:29 PM The idea of using M.2 is good. but still lets see how it gonna work in the end. Ill for sure see your youtube video and subscribe it gonna help lot of members to add 1-2 more GPUs using M.2 slots. :D :D :D :D :D
Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: evakka on May 22, 2017, 08:17:05 PM Nice trick using M.2 slots!
It's doable to power more than 6 cards with this PSU indeed. What OS are you going to use? Just mentioning... I suppose that you are aware that windows 10 consumes more power than Linux distributions... In any case, I would also suggest to use a "bigger" PSU. Even if you do all the necessary adjustments to the cards for reducing power, the PSU will work in its limits Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: mewhoyou on May 22, 2017, 09:42:34 PM Point taken but I will be using 1500 as I will push this with dual mining. Cards alone I expect 1200 watt and additional 300 for the system.

Cards alone I expect 1200 watt and additional 300 for the system. If you expect the system to draw 1500 watts a 1500w PSU is not nearly enough.....you will want at least 1800w. Pushing a PSU to its max rating will both lower the efficiency by a bunch, burn the PSU out more quickly, and most likely cause a bunch of crashes/hangs as the PSU will not be able to regulate its voltage properly at 100% usage. Thats on top of the instability you are building into the system by running too many cards on one board. That looks like the Asus Prime H270 Plus...I see no supplementary power for all those PCI-E slots. Is that not a concern for your build running 8 cards?

I will be drawing power from 2 PSU. I am looking at 850w gold. 1 psu will power the system, 2 boards, and all risers where as the other unit will power the remaning 6 psu alone. I had an issue splitting riser to two PSU which gave a reverse current and blew one of them. Either that or i get 1 PSU to power up the System and Risers and another PSU to power up the GPU. Rough calculations of 90watts per GPU alone would be sufficient. Ultimately this would be a better setup for me. But surely its going to be very messy....

You should not use a different PSU for the riser than you use for the GPU. The powered USB-cable risers should never have power beyond that necessary to carry the signal, and will not short something out (outside of a catastrophic failure). The GPU will draw some power from the riser, and some from the 6/8-pin on the card. These two sources should be the same.

Really interested in your results.
I'd try two identical 850W gold PSUs, they ain't that expensive either. My last build was 2x750W TT connected via copper wire and it is working fine. Just keep in mind to use same psu on GPUs and corresponding extenders. Power on AC setting on MBO also recommended. Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: xxcsu on May 23, 2017, 03:14:59 AM can not wait to see your working , dual mining 8 gpu setup on youtube ;D
Just because you added 2 x m2 adapters , your system not going to be plug and play ;) ;D forget 2 psu setup ,forget 1300 watts psu !!! get a strong psu with at least 1600 watts , or you going to have a very unstable setup ... Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: mewhoyou on May 23, 2017, 05:02:42 PM can not wait to see your working , dual mining 8 gpu setup on youtube ;D Just because you added 2 x m2 adapters , your system not going to be plug and play ;) ;D forget 2 psu setup ,forget 1300 watts psu !!! get a strong psu with at least 1600 watts , or you going to have a very unstable setup ... thanks ... i have just finish the frame... got a factory to start laser cutting the frame... ops ... :) about the PSU i am more keen on 2 850w than 1600w. Just that money spend seems more practical ... the more the better... its just 1600 with so much cable is not giving me the comfort. Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: muratizm on May 23, 2017, 05:23:43 PM Although 570 uses a bit more power, with proper bios mod, they can run around 110-120w max each card.
8 x 120 = 960w mobo ram ssd cpu is no more than 100w 1060w total. why 1300w psu is not enough? if it has enough vga (6 or 8 pin) cables and can provide enough AMPS for hungry graph cards, It probably can? however, buying 2x 850w power is probably cheaper and provide better current to whole rig. Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: Etherion on May 23, 2017, 05:54:15 PM Maybe you are more lucky than me but I could not detect any gpu using an M.2 to pci-e adapter. Got refunded at least.
I do have a 8 (RX480 8Gb) GPU rig running from a z270 with 1x3 pci-e switch. But I am using about 1500w of power. I am not undervoltage alot(-96mv) with memory timing shift and a little over clock on memory. But my aim is to get zero memory errors and have a stable system. Keep us posted on your m. 2 test run. Hope it works for you Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: Etherion on May 23, 2017, 05:59:03 PM I am running an 1200w and 650w psu on that system. All modular and platinum. Not cheap but power is expensive where I am and loading is MB+5gpu and 3gpu. About just under 80%

Try to remove the hassle of insufficient power when I push it further. Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: muratizm on May 24, 2017, 07:25:45 AM Yesterday we've tested rx570.
it shows 120w usage on default (+ modded bios ram timings) without any voltage tweak. msi armor 470 4gb shows 84w in full load in same system, but it draws more from wall. rx570 says 120w, but it's more accurate (perhaps 132w from PSU, but more from wall due to power factor, mine is 80+ psu no bronze/gold/silver) Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: xxcsu on May 24, 2017, 03:48:05 PM you always need to know a real power draw for your system ... Gpuz measuring only the gpu power draw , not any another components on the vga cards !
Always check the power draw at the wall. If you are using ur psu at max wattage , there is a chance your mining rig going to be very unstable . The optimal wattage is around 80% of the max rated wattage. Yes you can way undervlot , underclock your 8 cards system for dual mining , but you are going to lose from max hashrate on both coins you are mining . Yes you can run the 8 cards setup from 1300 watts psu , but then forget the max hashrate you can get out from your cards , in that case , better to build a 6-7 cards setup with proper bios mod , im talking about bios mod , not paste and copy mem straps !!! Dont be cheap with the psu !!!

Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: xxcsu on May 27, 2017, 03:46:55 PM Houston! U have a call ! if your system is up and running stable with 8 cards , im sure that youtube video you mentioned earlier is up ? Can we have a link ? ;D ;D ;D so we can see the miner program is running hours , days without any error with 8 cards stable ;)
Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: Za1n on May 27, 2017, 05:12:09 PM Nice project! Good to hear you got all 8 cards working. I will definitely check out your YouTube channel as well when you post it.
May I ask if you are running a Skylake or Kabylake processor on the motherboard? Reason I ask is I heard that some boards have had issues running too many GPUs with Kabylake processors.

What happened ? Engine failure ? ;D ;D ;D Can we have a youtube link as you promised ? So we can see the miner program is running hours , days without any error with 8 cards stable , or at least some screenshot so all of us can see your op system recognized all 8 cards and hashing ? ;) Your post From another topic looks like you have some power issue : There is a slight problem currently facing which is the mobo has insufficient power ... i am setting up a 8 card and the board is givin in. "the mobo has insufficient power" are you sure is not your PSU ? ;) or maybe you celeron cpu (paired with 4gb of ram) can not handle all those pci-e lanes ? ;) Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: Bare on May 29, 2017, 06:12:06 PM First thing I learned when I started mining is NEVER EVER cheap out on your psu!
Listen to these guys mewhoyou, psu is the heart of your rig, I even went as far as getting myself 1700w platimax,(which I know is an overkill for my rig with 4x390 but is capable powering 6x390, problem is you only get 5x 2x8pin pcie cables and you have to order 6th separately) Sure as hell never had any power related problems with any of my rigs. you can get a good deal for enermax platimax 1700w if you're from EU, ~300€ compared to all other competitors which are usually priced around ~400€ ;) Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: blacklig on May 29, 2017, 09:00:59 PM First thing I learned when I started mining is NEVER EVER cheap out on your psu!

You should better buy another GPU and some decent PSU for like 100 EUR. I use those "normal" brands for my PSUs and have problem like once or twice, got replaced under warranty and no problem till then. and to OP: yes, you will get difficulties with MB as there are also power lines giving juice to PCIes and if you are using 8of them, you could burn your MB.. Happened to me :) It is best to create your own powered PCIe risers so you are not drawing almost no current from MB..

I was able to run 7 cards but damn it was awesome when it was able to detect the 8th card but when start mining things get from bad to worse. Include the board going up to 80c which was scary.

I had actually written to the manufacturer and they mention they will look into my complain. I took things apart and place it on a temporary rigs as below. https://i.imgur.com/HL0AoxR.jpg Well I am getting a custom setup going. My team plans to build a 5U server rack with 8 GPU. Here are the prototype. https://i.imgur.com/9f5fBOQ.jpg https://i.imgur.com/EszsML4.jpg Title: Re: My first 8gpu rig 6 pci + 2 pci m.2 need recommendation on PSU Post by: devkowow on June 02, 2017, 05:04:18 PM First of all, 1300w PSU would be sufficient if you have enough cables. Buying expensive PSU - pointless, buying oversized PSU - pointless. You have to take into consideration only 2 things. Your system power draw is around 100% of PSU power rating or below and PSU is gold rated or above. That is it.
All those comments - get expensive PSU, get 2x1000w or what ever other wattage PSU are complete BS and are factless. Period. I got couple of 8 gpus (gtx 1070) rigs running with SINGLE 1000w gold rated PSU! Stable! First of all, to all people giving those random things like unstable, reduced lifetime etc I would suggest go and study little bit of structure of PSU and how they work. Most of normal PSU have 5 or more year warranty, meaning you can run them straight at 100% load of at least 5 years! End of the story. One I am using is Enermax Revolution 87+ 1000W PSU that have 4 12V 30A power rails. Quick calculation P=IV=1440W + sata cables that supply part of power to GPUs trough powered risers are on different rail thus there is even more total wattage supplied by PSU. And that is just amount it have to reach to have Over Current Protection (OCP) kick in. This is reason I would suggest using multi rail PSU if you require more then 500-650W - extra safety as if you have everything on one rail that have OCP, lets say 100A, then most of your equipment will burn out until OCP trips and switches off PSU. Most of PSU manufacturers will state total wattage produced from 12V rail while there are 5V and 3.3V rails that supply mobo, sata, etc that are not included and alone are extra 100-150W. Oh and in all my years working as electronics engineer, we design things capable of working way above values specified to customers! Currently I am building 8 GPU rigs with 2x750W Chieftec gold rated PSU just because it cost less then getting single 1000w-1300w.
