PSU (Power Supply) Advice for the ~500W to ~600W Range

[PClark99]

It takes more than a little trolling to blow me up, anyway, JEDIyoda had some valid points in what he tried to convey.

:beer: for everyone, now buy a blasted PSU so we can all move onto the next customer. 😉

The Corsair HX620.......5 years warranty, rails that won't budge and are clean, very quiet power supply....and its output is rated at 50C. That's impressive as most are rated at 40C, so you won't get heat devolting form the Corsair. Got one powering my C2D rig...and a water cooling setup, too. Hasn't stumbled once. Love the modular cables, too.

You wish, lol. I'm not buying until late May. That gives me a month and half of asking PSU questions.

To make things clear, I wasn't invalidating JEDIyoda's points. They were good and helpful. Just the methodology.

Anyways. Thanks for the info guys, keep it coming.


EDIT: Just when I think I have this forum software figured out and don't need to use the buttons, it doesn't work right. Argh!

Will the HX620 power say two 8800GTX a handful of harddrives and an optical drive, as well as various USB device?

Yes, Corsair did a test w/ two 8800GTX's in SLI along w/ a water cooling system off the HX620, its pretty much good enough for anything except quad SLI or a stupid number of hard drives, and it may even work w/ quad sli but thats pushing it 🙂 Any modern normal system even a SLI or Crossfire system can be powered just fine w/ the HX620

I'm finding results, per 8800 GTX of:

• 150W @ ocworkbench
• 200W (peak) @ PCWorld
• 155W @ atomicmpc (interesting to note, they list 2 GTXs in SLI taking 378W combined, hmm, 155 * 2= 310, whats eating the extra 68 watts?)

So, it looks like I could handle 2 GTXs, say 4-5 harddrives, a DVD-Burner, 4GBs of DDR2 1200 Ram, and various USB devices without taxing the Corsair HX620?

Anyone know where to find reviews on memory power requirements? I heard somewhere that the really fast ram, like DDR2 1200 can really draw a lot of power.

As for the harddrives, 15W is a good estimate from what I've read. The Seagate 7200.10 SATA use 13.2W peak.

Granted, most of this is hypothetical as I won't be buying two GTXs anytime soon, maybe within the next year to 18 months. I just don't want to end replacing my PSU because its to small in the future, but don't want to go crazy buying more than I really need. The budget is a bit tight, but I'm aiming to be as future proof as possible.
