Is it worth going big?

post #1 of 10
Thread Starter 
So my next build will be running an octocore bulldozer, crosshair V, 570 and two 9800GTX+ cards. I planned to get an AX1200 to leave room to grow, but what would I have to run to actually need all that power? And does anyone have any 80+ Gold certified PSUs they think would be a better price/usefulness ratio? Assume a bit more power draw than an 1100T for the processor, I know we can only guess there.

Thanks guys!

1200w WAY too overkill. 1200w is only needed for Quad-SLI rigs and the like.
If you are intent on upgrading your PSU, look for a good quality 750w for extra headroom, such as the AX750 or you could cut it closer by getting a 650w unit from XFX or SeaSonic

A good 650-750w would be plenty. 1200w would be a pure waste of money.

AX1200 would be way to much psu for that rig, that psu is made to handle tri sli type rigs. The 2 9800s just wouldn't put much of a dent in power consumption.

I can't really make any suggestions, there are a lot of good psu's available now.

CPU magazine had a decent psu roundup, http://www.computerpoweruser.com/Dig.../CP____1103__/

Starts on page 50

And more reviews starting on page 16, http://www.computerpoweruser.com/Dig.../CP____1105__/

Would a 750W be able to handle two 570s as well? Like I said, I'll probably expand and want to keep this PSU around for a few builds.

Don't get 570's, they are very prone to blowing up in your face. I would just rather get a single 580 and call it a day. It will easily be able to max games for a long time to come, and SLI 580's can be done on 800-850w good unit (XFX, SeaSonic, Antec, Corsair, Cougar).

Duly noted, will adjust according to new budget space. I'll drop it to an AX850, any qualms?

No, this sounds pretty much perfect.

It's always good to get it a bit bigger to allow for some breathing room.

/inb4 that's what she said.

750w is fine for two GTX 570's (650w minimum), and 850w is fine for two GTX 580's (750w minimum).

CPU couldn't review their way out of a paper bag. Did you really look at that list? They listed the Thermaltake TRX 1200W as a high end PSU--a mediocre Compucase/HEC unit that shouldn't be on ANY recommended list. Yeah, that belongs next to the HCP-1200. And they have the Diablotek PHD350 in there as well. Seriously? And a Logisys piece of crap from Keerda too. And no SeaSonic X on that list. That magazine just failed the fail test and now it has to work at Fail Burger serving fail with extra fail sauce to this guy:



Derpa durrr, TRX-1200M has 99% PFC just like every other APFC PSU made in the last 20 years! On the recommended list it goes! Durrr.




No offense to you or anything, but I'd prefer if you didn't refer people to that. OCN has a Recommended PSU thread of its own at the top of the PSU section which has much better recommendations than CPU does.
