Need PSU for Bulldozer build + any single GPU I could ever want.

post #1 of 17
Thread Starter 
I've updated this thread to reflect a more realistic outcome of the build.

Getting a rig ready for the release of AM3+. Should Bulldozer = Fail in comparison to Sandy Bridge, then things may change. So far, the build looks like this...

CM 690 II with six 120mm fans.
XSPC Rasa RS240 kit.
Enthusiast level AM3+ motherboard.
Octocore Bulldozer.
Any single video card solution.
2 SATA HDD's.
1 IDE ODD.

I want to be able to use any single video card solution available, even a dual Fermi card should I ever wish to try it. But most likely, I will never have 2 physical cards.

Right now I'm thinking 750W and looking at Corsair and Seasonic 750's.

At least 850w *high end* brand like corsair, preferably single rail (or modular multi-rail if necessary) but a 1000w would be better.

Why are you limiting your budget with the power supply when you will clearly have a system that does not appear to be on the same constraints? The PSU should always come before other components in terms of cost because of how vital it is.

Also, the most you would need for any dual Nvidia setup would be 850 watts, and that's if you'll be getting dual GTX 480's. Everything else, including dual 580's could do with 750 watts or less, depending on the GPU.

Mainly because I'm pretty sure they are out there. My last PSU was a Corsair CX400 that I bought for a little less than $60 Shipped (also had a rebate that I never claimed). That particular model was regarded by many to be absolutely the best in it's class.

Should research and community input prove that I should seriously consider increasing my budget, I may do so at that time, but until then I am investigating my options at the $100 price point.

Also depends on what graphics card you plan on getting, but 850W is way too much. 750W is way too much. 650W is still pretty high.

Bulldozer won't be that power hungry and with 1-2 video cards, you don't need that much.

Yea, so I was messing around with the eXtreme PSU Calc and I came up with ~600W.

That was with a Phenom II X6 @ 4GHz and dual GTX 460's and a ton of accessories, including water cooling and lighting.

I'm gonna start shopping PSU's in the 600-650 range.

I would recommend at least a 750 watt, preferably a 850 watt if thinking of something like dual GTX 580's. Thats what my sig rig uses while folding.

I'm seeing lots of highly recommended units in the 600-750W range for under $100. I've got some reviews to read, but I dont think it should be too hard to reach my goal here.

Now, c'mon, 850W PSU's? For real? I just dont see it.
