Would my 850w cut the mustard?

post #1 of 31
Thread Starter 
Im upgrading my CPU to a i7 970 and adding a GTX580, both will be overclocked and the system will be folding 24/7.

Would my 850w PSU cope? If not what wattage would i need to get?

I've been out of the loop for a few months

I say, "you'll be fine"
I'm rocking an 850W with two GTX480s in Sli
My CPU is at 4.3GHz and my two 480s are at 760/1520/1900.

850W is fine.

I imagine the rig will pull ~650W from the wall @ load, maybe a bit less. (assuming moderate OCs.)

I'm honestly not sure, that's a weird configuration.

Your psus only 768w@12v line make me think that it might not be enough.
