In that I would have breathing room with an 850w PSU for the x2 580/2600k setup? I mean that does seem like it would be cutting it pretty close, especially since I have plans to overclock both of the cards, along with the cpu.

Since most of you are recommending getting a psu that's less than 1200w, what psu's would you recommend specifically? Like I mentioned, I've been looking around for awhile now, and I haven't been able to find anything worthwhile, other than the AX1200. Looking at newegg right now, these are some of the ones that seem pretty decent...

ZM1000-HP

OCZ-ZX1000W


COOLER MASTER Silent Pro 1000W

...but they all seem to have some sort of really annoying downside to them. The Zalman one doesn't have a power switch, the OCZ one is lacking a MOV and has some pretty short cables that would require extensions, and I've heard somewhat mixed things about the Cooler Master Pro.

dude..... you do realise in all honestly that system will need 600watts right? when we suggested 750w or 850w we were taking headroom into account, so unless your gonna get like 40 highpower fans along with 50 hardrives and a freakin lazer cannon in your 5.25 bay we really mean it, a GOOD 750w would be fine, and im goung to point out, most 750watts can do a higher peak power, lets say a 750watt continous supply, that means it can do 750watts 24/7 with ease, every now and then ie peak fluctuations it could pump out 800-900 watts for a short time, were serious unless your going to be using sub zero cooling 750-850 would be GREAT for you

EDIT sorry for spelling and grammer, im tired right now ill fix it in a bit

Zalman's ZM1000HP is good, but costs more then competitors. The Seasonic X-850, Antec SG-850 and the Corsair AX850 are excellent 850w units. You don't need more then this, even with overclocking.

Yeah, I've been looking around on newegg for a decent surge protector (I already have one, but it isn't very good) if I were to go with one of those OCZ ZX PSUs. Any recommendations for a good surge protector to make up for the ZX's lack of a MOV?

Also, I've been re-reading some reviews I've looked at for the past few days in regards to the power consumption of x2 580 cards, and like I mentioned, with an ~850w PSU, I would be cutting it really close. Most of the reviews have shown the load power consumption to be almost ~800w. Like I said, I want some breathing room (more than ~50w), and I really don't want to constantly be stressing the PSU whenever I'm playing a game or something (I'd like for my PSU to live for a couple years). This is why I'm looking to get a PSU at around ~1k-1.2k. If I could find a solid 1k PSU, then I would get it, but like I mentioned, the majority of them are really mediocre.

If anyone here has some recommendations for a good 1k PSU though, that would be great. For instance, I was reading through some johnnyguru reviews and noticed that Thortec 1.2k PSU review. It looked like a pretty solid unit, and so I looked it up on newegg only to find that there is also a 1k version of that Thortec PSU. Does anyone have any opinions on this PSU? It doesn't seem to have too many reviews out, so I can't really say for sure if it would be worth getting.

Less in bulk.

The newer Silverstone ST series is pretty good with their 80+ gold rating...just throwing my 2 cents in.

Definitely go for a quality 850W. Here's a proof you don't need any more than that : [ame]http://www.youtube.com/watch?v=QHReC2yAmMc[/ame] He's running SLI GTX 580s and an i7 950 off a TX850.

i have 2x asus 570 DCII SLI on my asus rampage III with a 980x stock and a antec cp 850 psu.

When i play battlefield bc2 the power usage goes to 680-7... and after 20 min or less the game crashes or it all ends with a blue screen.

So i took one DCII off and now i play with 500W power usage without OC my 980x everything is working great with prime and other tests for gpu.

Bottom line: If u want to OC your SLI 580 cards and OC your 2600 to 4.8 or so... u will need at least 1000W PSU with 80+gold... just to be sure

I was worried when I recently bought a second 480 whether my Seasonic 750 watt would provide enough power for both cards and the system.
As in my listed specs., the cards are at 800/2000 24/7, with a moderate overclock of 3800MHz on the cpu.
It's been a couple months now and the Seasonic 750 hasn't missed a beat in any gaming or benchmarking I do.
That's not to say that any brand of 750 watt psu would be as reliable, but a good quality unit can do the job.

Yet there are naysayers that insist you should have a 1000, 1200 watt, etc.
Nvidia being one of them.
I do intend to eventually upgrade to a higher wattage psu, but for now it isn't needed.
