Best PSU for 2 GTX 275's with a GTX 275 Co-Op (GTS 250 on same PCB) and a Q9550?

post #1 of 29
Thread Starter 
Any help greatly appreciated, would like a few options at both ends of the pricing scale, haven't been paying attention to PSU's lately and wondering if any new 80+ Platinum models are wowing the market.

What's your budget and where are you buying from?.. any solid 650W unit or above will do.

Wait, so 1 275 and a 275 co-op?
or 2 275s and a 275 co-op?

3 cards or two?
I see your sig-rig only has two GPUs, but neither is a co-op...

Just trying to clarify.

3(or 4 depending on how you look at it) gpu's on a 650w?

As far as I understand the OP, there are two 275s and a 250 for PhysX(30/40W at most).. and if I understood it right then yeah, a solid 650W is plenty.. if there are three 275s and the 250 for PhysX, then we're talking about an 800W or above unit.

Gtx275 is a power hungry card,219 tdp,I had this card.
So would never recommend 2x gtx275 on a 650w psu.

I wouldn't look at anything below 850w. 3 GTX 275 (2 regular and 1 Co-Op) + a GTS 250 (in the Co-Op) do eat a bit of power.

And if you want to OC, no less than 900w is required.
