How much PSU wattage for these builds?

post #1 of 8
Thread Starter 
Hey,

I'm wondering how much wattage I'll need for these builds (assuming an 80+ gold PSU):

CPU: i5 2500K
GPU: 560 Ti, 570, 580, 2x 560 Ti, 2x 570, 2x 580

I'm guessing the following: 500, 600, 700, and 750, 875, 1000. I imagine that would be correct or very close.

My first question is am I right? Are they OK for the CPU and those cards at stock clock speeds? And my second question is will they be OK / what would I need for a 4.4GHz OC on the i5 (max) and a 50% OC on the GPU (well past max).

I'm also guessing the GPU OC will be drawing the most power and the CPU OC will make little difference?

Cheers

I'd recommend...
500, 550, 600, 650, 750, 850. But they won't draw that much power. Always to good to play on the safe side, though.

1x GTX560Ti = 400/450w
1x GTX570 = 450/500w
1x GTX 580 = 500/550w
2x GTX 560 Ti = 600w
2x GTX 570 = 650/750w
2x GTX 580 = 750/850w

min/recommended.

Ah great, thanks. Would those recommended values be fine for the OC too?
