Dual-PSU - Any tips/advice/links-to-1500W PSUs? - Page 2

Two GTX 590's will run happily on a good quality 850w. Overclocked, 1kw. Who told you it would take over 1600w?

590's? No, I don't believe that one bit honestly. They're a solid 350-400w GPU each (I'd have to double check). But its recommended to have a quality 650w PSU for just one 590 by our PSU experts here.

Keep in mind, a GTX590 is 2x GTX580's in SLI on one card, with gimped VRM's (so less power draw due to less OC potential).

Wow. Do NOT OCN at 3 AM. Two GTX 580's will run happily on 850w, two GTX 590's start at 1kw. Sorry But you still don't need two in parallel to power what your looking for, it took four GTX 580's under Furmark to climb to that much power draw.

And with that kind of system (quad 580's with high overclocks), a 1500w PSU would be used, not 2x 750w PSU's.

Problem's been sorted now; someone linked me to FrozenCPU, and they have 1600W PSUs.

I had to revise it once before posting here; the build I had planned used 1673W.

you really dont need a 1600 watt PSU, BTW do yourself a favor, buy a wall socket watt meter, and itll tel you the pull of the PSU, i bet youll be suprised.

What EXACTLY would be running? Because two 590's and a severely overclocked SR-2 could run off of a 1500w.
