Hi! I am a relatively new to the mining community, but I am trying to build myself a mini version of an altcoin rig. First I want to try out two GTX 770s. I am buying them really cheap just so I can try this out.

My question is what PSU can you recommend for this? As I am not quite sure what the power requirements for those are, and what connectors do I need to have?

Heyo Tor Eivind

I'd say probably a 700w and up from there PSU.
Since one of those cards can use up to 230w alone, you're going to need like 600w as a bare minimum.
EVGA's SuperNova series has some nice PSUs which would do you good.

Cheers

Hi again. Was searching a little and found a PSU I wanted to buy. This one has 4xPCIe 6/8 pin power connectors. I guess the GTX 770 require both 6 AND 8. I was wondering if on a modular PSU, is it possible to add more PCIe 6/8 pin connectors, just buy the cables alone, and plug it in the PSU?
