Total Power of GPU Mining Rig

[canozturk21]

Hi All,

I'm going to set a rig, my components are listed below. But I'm not sure about total power for my rig.

Is my psu enough ? There are 2 options, adding 1 psu more or selling one card and go with 5 gpus.

1-) 6 x MSI RTX 3080 Gaming Trio X ( Suprim bios will be flashed, 220w power limit set)

2-) 6 x Riser Ver009s

3-) Biostar TB250 btc+ mainboard

4-) Pentium G4650 CPU

5-) HyperX Fury 8 gb 2400 mhz cl15 ram ddr4

6-) 32 gb usb3 flashdisk for Hiveos

7-) Xigmatek X Miner 1800W gold psu ( %88 effiency under %100 load)



Waiting for your advises, thanks in advance !

Good PSU
Dc output 12V 138A 1675 W
This power supply has 6 wires with 2x8 pin connectors. This is enough for 6 video cards.
But with the power supply of the raisers, problems may arise, because you will not have enough wires to connect each raiser to a separate wire.
You only need to use Molex or 6pin raisers

Update
your video card has an 8 + 8 + 8 pin power connector.
one power supply won't be enough because you won't have enough power connectors

And why will you flash the suprim bios? You don´t need more power, you need high mem clocks and lower gpu as low as you can without impact on your hashrate.

[FP91G]

I would not have flashed the BIOS either. For this farm, you need to use 2 Xigmatek X Miner 1800W gold power supplies or order a 2.5 kilowatt server power supply with 30 8-pin connectors, so that you have enough power for video cards and raisers and you don't have to use Molex-6-pin adapters to power the raisers

[mak013]

1 PSU has 14*(6+2) PCI-E connectors. You rig need 6*3 for GPU and 6 for risers. It is 24 connectors. Xigmatek has decisions 1200W and 1600W, that have 12 connectors each. So you can buy 2PSU 1200W or 1 server PSU with 24 connectors(or 32 - if you`ll decide to make 8GPU rig)

[canozturk21]

thanks for all comments, I've already purchased the parts....

I should buy one more psu regarding to your advises

Some people has low hashrate problem due to power limits. They solve the problem by flashing Suprim bios to Gaming Trio X.

I will not trust that PSU, it is too small for 1800watts anyway i cant say it for sure until i take it and open. Man you got so expensive GPUs and getting cheap psu not logical. Get proper PSU for those beast, good luck

[JayDDee]

It's a mistake to engineer power requirements based on 1 algorithm. 3080s are rated at 320W, that's
the number to use, or higher if you OC.

It's also a mistake to engineer to 100% of the PSU's power rating. 80% max, some say even lower.

You're also over budget for a 15 Amp circuit if that's what you're using.

Solid advice those cards cost over 1k each.

He simply should do 3 card 1000 watt psi mobo's

and run 2 mobos.

I have six slot mobos that will do 3x 3090 at 275 watts each I use a 1000 watt seasonic focus.

He could do 3 on a six slot onda board every other slot and use a 1000 watt psu easy peasy build.

or do 4 and 4 on two of these

these will even use cheap bitmain apw3+ psu

[Commie]

Definitely not enough. If you change algo or for any reason your OC settings will reset you will fry your PSU. I use 1200-1300W PSU for each 3 3080 cards. Plenty of juice and PSU itself will last forever.

I saw burned corsar, seasonic, superflower, evga. Of course i sw burned chinese PSUs and server PSUs. I cant say, that the was 1 top PSU for 10 chinese - it was same, and i have to say that even top-PSU can burn and cheap PSU can work year by year.

it is better not gamble with 6 rtx 3080 on board. You saw burned psu because many people dont know what they are doing.nearly all psu are chinese but there is good china psu too. I can tell it if i open it and see what is inside. For this ximatek it is gamble there is no review what inside and power test. Server psu gets burnt because 1: they are very old and most of them are used many years.2: people load them too much. in my collection i have thermaltake 1200w people say it is bad psu but it is good for many years i dont know how people burns them. i have server psu from dell hp working many years, i have 2 chinese psu 1600w and its bigger than this one 1800w, if i pull more than 1000w from it transformer gets extremely hot (80-90) thats why i keep it 900w and it working many years. people think ooo 1800w ok then i can pull 1800w and use it then problems.on my free times i load psu before mining and test it and measure temperatures if it is cool then its good. but people have no idea how transformer gets hot really hot also coil can get 100C it is serious temps for components near that.

This is gamble in any way. Nowadays there is no differences between goood named PSU or chinese. In any choice mostly you are getting the same components from 1 manufacturer. If anyone load PSU too much - problems will get any PSU again. 
A can say that several years ago chinese PSU were awful, now they are about top named PSUs.

I have had XFX, Superflower, EVGA, Corsair, Seasonic and Enermax PSU,

Maybe total 15, only 2 burned. Enermax Platimax 1350W and Corsair TX850M.
Enermax asked me to send the psu for investigation, i got new one even the warranty was over.
They said that it would be almost impossible to burn those PSUs

On Corsair the fan failed and it killed the psu, also one 1250w XFX had same problem but XFX had better protection so it shut down
before burning the unit, got new one from xfx from warranty.

I Would only go for gold and better rated psu and keep running them under 70%.

Maybe only monster for 6x3080 would be SuperFlower 2000W (missing still some 8 pins so needs splitting) or some server psu.
Maybe better do 2 rigs or 2x1200w PSU or maybe 1x850w+1x1800w. (amount of 8 pin connectors seem to be problem)

Hi All,

I'm going to set a rig, my components are listed below. But I'm not sure about total power for my rig.

1-) 6 x MSI RTX 3080 Gaming Trio X ( Suprim bios will be flashed, 220w power limit set)

2-) 6 x Riser Ver009s

3-) Biostar TB250 btc+ mainboard

4-) Pentium G4650 CPU

5-) HyperX Fury 8 gb 2400 mhz cl15 ram ddr4

6-) 32 gb usb3 flashdisk for Hiveos

7-) Xigmatek X Miner 1800W gold psu ( %88 effiency under %100 load)



Waiting for your advises, thanks in advance !

i'm expecting 1550w, just buy wattmeter, and to tight for psu handle your rigs, it will degrading faster above 70% heavy continues load, and the power draw will depend on the ambient temperature so i think your power wil fluctuate around -+ 5%

[FP91G]

Why did you scare a beginner miner so?
2 Xigmatek X Miner 1800W gold power supplies would be a great solution for his farm.
He chose video cards with 3 connectors of 8 pins, so he will not get to use 1 power supply for the computer.
BTC-37 Computer Motherboard is a good board for a server power supply, but if you have a non-server power supply, then problems with connectors will begin

yes if he gets 2 of that psu for that rig it is more safe.

[canozturk21]

Thank you for your all comments gents. I'm gonna add 1 psu more.
I'll keep this post updated when I complete my rig.
