350W PSU enough for 6800?

[impemonk]

I posted this earlier but need more opinions...

- - - Hey, I am a bit new to this forum and AnandTech.com but from what I have seen many people in this community are helpful. So, with that in mind I ask a question concerning my PSU on my full sized Centurion 5 tower. Is my Cooler Master 350w PSU enough to handle a geforce fx6800?

My system specs:
ASUStek P8P800S w/ Pentium 4 2.8Ghz w/ Hyper-Threading technology (800FSB)
512MB of Geil PC3200 (DDR400Mhz)
80 gig MAXTOR 7200 RPM HDD
1 CDRW drive
1 floppy drive
4 80mm LED fans
One 120mm fan
1 blue cathode light
Cooler Master 350w PSU can be found here:

I was browsing and I found a good deal for the 6800 which was up for like 250 bucks. For my PSU, the specs are +3.3v = 18A, +5v = 25A, +12v = 16A. If I cannot handle the 6800 would I be able to use
the fx5900xt? That is my fallback vid card in case my current PSU cannot handle the 6800. I am hoping to get the 6800 non GT/ULTRA because I want to be able to play games like Rome Total War, Doom 3, HL2, and Battlefield Vietnam without blowing up my wallet.

anyways, thanks to anyone who helps.

i'm going to say that you'd be pushing your PSU to the edge if you install a 6800.

I think it might be pushing the psu a little too far as well. I wouldn't revert to a fx5900 though. At the very least get a 9800 pro or wait for a 6600 gt. 6600 gt's perform better than the fx5900s and the 9800 pros and will not push the psu as hard as a 6800 would.

what brand is the PSU? i'm leaning toward recommending a new PSU

I was running a GT on a 320w PSU up it until about a month ago and it gave me no problems.

That should be fine. I don't hear very many opinions cooler master PSUs, but CM usually makes solid products.

That being said, the 6800 would have a better chance of working in your system than a 5900XT. That's because the FX 59XX line sucks down a lot more power than a vanilla 6800.
