PSU for 8 x 1070

Mining
1

Hey all. I have little experience with the 1070’s. My current rigs are 8 x 1080 units and im running a 1600w and a 1000w in combination to power them.

What kind of powere are you guys using to power 8 x 1070 gpus?

Thx

2x750watt psu will be enought

my 6x1070 using cx750+tx850 draw at wall 1000watt

Well, for approximation use this formula for your 8 GTX 1070

#of GPU * GPU Power Rating * 125%

8x150Wx1.25=1500W
1500W would be save, assuming your PSU is at Gold and above (Gold, Platinum, and Titanium)

I’ll be trying this

The wattage is way too high for 8 GTX 1070 Mining rig.

Also, per their description it uses 220V-240V. Is the wall outlet outputting these voltages?

Most importantly, why is it so much cheaper then EVGA 1600W P2?

it’s cheaper and provides more wattage, that’s a good thing.

For the voltage, I guess it depends on where you live. My wall socket is 220-240V, I guess USA is 110V? So yeah, probably can’t use this if you live in USA. Need a transformer if you wanna use it

Well, I personally believe better quality = more expensive.

I don’t know where OP lives.

I typically only like to use the EVGA Platinum or Titanium series PSU. Firm believer of you get what you pay for.

I’ll probably stick with a 1600w to be safe.

Thanks all.

it’s probably cheaper because there’s no ATX connectors. It’s purely for GPU.

Depends on how many GPUs you have too I guess, I have 12

I ran into the issue that the 1600w PSU wasn’t available when I was building. I have 12 computers running the 2x750 EVGA platinum PSUs. They work like a champ. As a bonus, they were only about $315 with the add2psu to connect them. The 1600 was at least $410. Every dollar counts. Something to consider that is awesome on linked PSUs is that you have additional connectors making it MUCH easier to configure the computer. A 1600w PSU has 9 VGA connections and 2 750s has 12 because each has 6. That has come in very handy. You will also get more cords to complete the build.

If I had it to do over again, I would use server PSUs as they are SO much cheaper. They are also easier if you want to use 220v (more efficent and fewer plugs) but live in the USA.

This is what I WISH I would have known about before starting all of my builds. They offer a breakout board to power the MoBo CPU and SSD. I would have saved about 50% on my PSUs with this.
