Looking for a 1000W PSU for my new system

post #1 of 43
Thread Starter 
I'm looking at the SILVERSTONE Strider Gold ST1000-G 1000W which will be powering two GTX 570 in SLI. My i7-2600k which will run on an Asus Sabertooth P67 won't be overclocked. Will this power supply be sufficient, even for GTX 580s and are there better power supplies out there? I'm looking for stability, performance, single 12V rail, SLI/Crossfire ready, and it has to be 1000W, and I should be able to run two GTX 580s with it.

Let me know. Thanks!

Why does it have to be 1000W?

A decent 850W could easily do 580 SLI.

You only need an 800-850 w for that.

I'd recommend the LEPA G800, in terms of performance and build quality, it's one of the nicest 80+ gold units on the market.

Gtx580 is 245w and GTX570 is 220w. A solid 850w unit should be fine for that SLI rig. That 1000w unit can pull 83a/996w on 12v so it has plenty of power.
post #5 of 43
750w is fine for two GTX 570's. I would get the XFX BE 750w over the LEPA.

And why are you looking for a single rail only?

The reason I want a 1000W unit is because I might upgrade the video cards in the future to something more powerful and I don't want the power supply to reach full load. So which 1000W unit should I get?

OCZ ZX 1000w is cheap. It's probably the best value around right now for 1000w units that perform well.

By the way, the Sparkle Gold 1250w is $180 at the moment, with the promo code.

Like I said, I'm not looking for cheap. I'm looking for best performance and stability. Can someone tell me if the Silverstone power supply I have chosen is a good choice?
post #10 of 43
I like this site for checking how well the power supply tested out. Give a go at it here and then you can decide pretty easily then.
