Yep, it should run the card fine as long as you have 18+amps on the +12v line, when mine was a single it ran fine with a powmax 480watt with 18amps on the +12v line.

As for it being a good upgrade, it depends what games you play, if they are all titles from 2006 and before, then your probably good to go, Even with SLI 7800GT's its looking like they are quickly being outpaced for 2007 games, example is cellfactor revolutions free game, i have a avg framerate of 15fps, i haven't checked to see if its actually using both cards though. I'd have to say it might be a good deal for 100$ or less, i bought my 2nd one shipped for 105$

I was looking into downloading lost planet demo for the benchmark but looks like a vista only title.

The link you supplied for the PSU shows a spec of:
+12V1@20A, +12V2@20A

Thats way more than enough for a 7800GT!!

Yours and my rig are very close. I use an overclocked 4200+ X2 with SLi'd XFX 7800GT Extreme Edition cards and games still run at a very respectable frame rate 30+ @ 1680X1050 res with nice levels of AA and AF. This includes Stalker and Supreme Commander.




To the OP. Yes your 400w PSU will be fine, however if you want to go SLi with them, you'd need to upgrade.

good to hear with SLI 7800GT's but a single will be a drag to play even 1600x1200 no AF/AA i'm sure.

I finished downloading lost planet through steam, and loaded it up, running at 1280x720 and all defaults, it isn't the greatest but this is only a demo, not a finished product, the results are:

I tried to enable multi-GPU but when i tried to play test again it was the same frame rates and even my Tt PurePower was only showing load on the 12v1 line mean it definitely wasn't using SLI power, guess i'll have to play around with it now

EDIT EDIT EDIT:
I got SLI to work with AFR1 so far, did a quick test with my 7800GT's with default game settings, so without further adu:
 
Looks like a very respectable increase in frames and all around visual acuity. Super nice. 7800 GT's definately still have life in them, at least another solid year. Remember, factory overclocked 7800GT's were only 4-7% slower than a non overclocked 7800GTX. SLi'd 7800GT's are about 10% faster than a single 7900GTX or x1950XTX at resolutions below 1920x1200.
