Will my 500w PSU (w/ ONE +12v rail) support my X1950 XT?

the label on the side of the PSU says the +12v rail is rated for 34A. Here are the rest of my specs:

Pentium 4 3.2 GHz (w/ HT)
Asus P5RD1-V Motherboard
Geil 2GB DDR (PC3200) RAM
Soundblaster Audigy
80GB Serial ATA HDD

What do you guys think?

this link to common PSU myths might answer your question. #8 of the list deals with your situation. Whether your 500W PSU can do the job I dont know, you didnt list enough specs. This information might be handy though.

well a x1950xt pci-e will use like a bit over 100w for a single card,and that p4 around erm well 75-90 somewhere around that ... prehaps, yea if that 500 is not 'PEAK' yes it will, also depending how many hard drives you have.

so for cpu and gpu it would add like around 200w,ive read about gpu power useage and the x1950xt is rather power hungry and i saw how much basicly it took, so if that 500 watt is not peak then yes the power requirements will be fully supplyed depending if you put the card in properly and have experiance because that pci-e slot won't fully supply it with power, and thats how i am thinking it.

the rest of the system is not power hungry as that processer and graphics card, i can tell you that , they both = 200w, the rest well that 500w will handle it, if its not peak..

That should work well, a quick run through the psu calc shows it is under 340w so ideally anything over 12v@26A is recommended.

Should be easily enough.

I've got 2 hard drives, a DVD writer, X1800XT overclocked, 1gb RAM, an overclocked Opteron and the PC runs with no problems from a 400w PSU.
