soon i'll be getting a new GeForce 7900GS upgrade to replace my currently fairly weak 6600 card. Fairly cheap now, eh =]. i have only a 350W PSU though, and its years old, I believe it to be failing (wierd smell when my PC is left on for hours at a time, the machine even refuses to power up if i leave it off with still plugged into the mains..)

I presume my 350W PSU marked as "max 22A on the +12 rail" isnt powerful enough as the 7900GS states 22A at a minimum. what should I aim for? 400W? 450? as i'm a student I cant afford much, but ah well. in terms of amps on the +12, how many is recommended?

my system (currently): 1 stick, 512mb DDR2 ram (i run Linux so its enough ;) ) 1 160GB sata HDD amd athlon x2 4200 asus motherboard (A8N-E i believe)

please dont tell me i dont need a 7900 card to game on linux, I have plenty thats running 20-40fps, and its annoying >.<.

does it _need_ a 6pin connector?

forgot to mention I'm a student so, well Extra Value 550W ATX Silent Neon PSU - 12cm Fan/PPFC (no power cord) - Ebuyer more watts, has 30A on the +12v, any good?

i would stay away from any extra value psu as there more likely to go bang, as for the 6 pin connector im not sure but i would expect it would need more power than the pcie slot could provide on it own, also if you where looking for some thing a bit cheaper this should be enough to power it Antec EarthWatts 380W 80%+ Efficiency PSU - 80mm Fan 4x SATA PCI-E - Ebuyer

it not all about the wattage its also about how many amps are on the 12v rails, coz that antec is 380 sustained watts with 26 amps on the 12v rails where as the ez is 600 watts peek power and around 300-400 watts sustained output with about 15-18 amps on the 12v rails, also the antec is manufactured to a high standard where as the ez is just cobbled together with cheap parts
