I’m working on building a small mining rig, but a bit in doubt about my PSU.Which PSU would be sufficient to power 2x Nividia GTX 1070’s GPU’s for mining ZEC? I’ve read it takes about 170W per card but I want to be really sure about this. I have a PSU of 520W lying around but I’m afraid that will be a bit short… What do you guys think? Or maybe I should get a PSU of 600W or higher?
Other hardware is rather light:
Intel Celeron G1840 Boxed → CPU
Gigabyte GA-B85M-D3H → MOBO
4 GB of Ram
SSD drive 128 GB
I am running 4x 1070 on 750W Bronze Corsair PSU with plenty of juice left.
You can probably run 2x1070 and drop to 550w PSU if its of good quality, but I would be careful. Make sure the PSU does not overheat - keep good ambient temp in the room.
Usual power for 1070 is between 170 to 220 W depending on the 1070 model. (if not down-clocking)
Do your math (adding your other cpu, mb etc consumption) if you want to run on full power/speed.
If you have some $$, just get a decent PSU. You spent 400USD+ per video card and you dont want to get a decent cpu which is like 15%-20% of the price of one video card
