Here are the official power requirements for the new ATI Radeon HD 5850 and HD 5870 video cards.


ATI Radeon™ HD5850 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard

500 Watt or greater power supply with two 75 watt, 6-pin, PCI Express® power connectors.

600 Watt or greater power supply with four 75 watt, 6-pin, PCI Express® power connectors for ATI CrossFireX™ technology in dual mode.


ATI Radeon™ HD5870 System Requirements:

PCI Express® based PC is required with one X16 lane graphics slot available on the motherboard.

500 Watt or greater power supply with two, 75 watt, 6-pin, PCI Express® power connectors.

600 Watt or greater power supply with four, 75 watt, 6-pin, PCI Express® connectors for ATI CrossFireX™ technology in dual mode.

The power supply recommendations are for an entire pc system.


Corsair has a reputation for high quality power supplies that consistently earn high marks in technical reviews. They are reliable, stable, and come with a 5 year warranty. Some of the newer models come with a 7 year warranty.


If you are positive you will only be installing one video card, then the Corsair HX520 would be an appropriate choice.

You'll want the F3 not the older F1 or the 7200.12 HD's.

NZXT Sentry 2 for the fan controller.

Stick w/ the on board audio until you've at least decided whether it satisfies your needs.

As for PSU, you considering Xfire (2nd GFX card) as a future upgrade ? I am going to assume no based upon your MoBo selection. This will get you twin GFX at x8 x8

this will get it at x16 x16
http://www.newegg.com/Product/Product.aspx?Item=N82E16813131594

PSU - For single GFX and moderate OC'ing you'll want a 500 - 650 watter w/ a 9.0 - 9.5 performance rating at jonnyguru.com or better; for twin GFX and moderate OC'ing you'll want a 650 - 850 watter w/ a 9.5 - 10.0 rating.

I usually start here:

Of the ones you listed, I'd limit your choices to the HX series.

Ok thank you.
As for the fan controller and the sound card and hdd i already have them.

as for the PSU i was just worried because when i did a calculation here http://www.thermaltake.outervision.com/Power of the Watts needed it came out to almost 500W and something.
so i thought it might be too tight and with no space for aging, as i intend to keep the system for atleast 3 years, aging is something to take into consideration i think.
as for the second GFX card yeah most probably won't be adding it.

I happen to have a Corsair HX620 that I purchased when the psu was first introduced. I used it constantly for almost 5 years. I still use it in my emergency back-up system. A few weeks ago I conducted a couple of torture and temperature tests in response to questions about fans mounted on a case side panel. The voltage was still well within specifications and rock steady. I normally would have installed that psu in my new system but I decided it was time I had an emergancy back-up so I did not pull it out of my old system.
