What are the 1950x pro power requirment

i have a 450wat thermaltake TR2 430w PSU. Will it be able to run the card.

I have, 2 sata hdd, 1 dvd rom, the power savin version of the AMD 4200 x2 cpu, and a regular asus matx motherboard.

Other then that there are 3-5 usb devices that run.

You wont have any probs whatsoever with the x1950pro and your rig.

I estimate your MAX power consumption on the 12v rail to be as follows:

AMD 4200+ 65w @4600+ speed....................................48w
X1950Pro....................................................................66w
2 SATA 320GB Hard Drives...........................................32w
1 DVD ROM.................................................................16w
2 120mm Fans.............................................................12w

Total Estimate Power Consumption on 12v rail................174w
Total Estimated Amps Consumption on 12v rail...............14.5a

All other components will draw power from the 3.3v and 5v rail.

The above assumes you are overclocking your 4200+ to the speed of the 4600+. Actual power consumption will be less when playing games 'cause your HDDs and DVD will not always be spinning. Figure around 154w or less.

The Thermaltake TR2 430w has 18 amps on the 12v rail and therefore should be sufficient:

You don't need a 550W power supply, and 30 AMP is what they say for the X1950XT assuming a fully loaded system. I'd say you would be fine with much less, but that said your PSU has a wimpier 12v rail than most quality 350w PSU's. I would not expect that 18 AMP 12v rail to be enough for the X1950 pro. I also hate the lack of info on that PSU label. Where's the combine max output specs? I had one and sold it in a non gaming rig.

ATI claims the following power requirements for the x1950 pro, as found at: http://ati.amd.com/products/radeonx1950/radeonx1950pro/...

single card: 450W with 30 amps on the 12v rail (fully loaded)
crossfire: 550W with 38 amps on the 12v rail

(It's either a mistake, or ATI just named the page incorrectly. In any case, these are the same requirements as the xt & xtx, as a previous poster indicated, so they could be overstated).

That being said, I'm running the following without a problem.

Asrock Dual Sata2
Opteron 146 (@ 2.4Ghz)
sata300 hd
ata133 hd
dvd burner
cd-rom
x1950 pro pci-e

And it all runs just fine on my 350W Antec Smart Power (SP350) which has a total of 25A across the 12v rails.
