I have decided to hit the good 'ol full system upgrade route and I am concerned that I will not be able to move my PSU over to my new system.
FSP 350 watt blue storm psu, 30a on 12 v rail (dual 12v, 15a each)
The video card I'm looking at is the 7800gt (probably XFX) [says you need a 400 watt psu with 26a on the 12v rail)
probably - 3200+, asus A8N-E, 1 gig of mushkin ram (2x 512mb)
1 sata hd, 2 ide optical drives.
 
If you're willing to spend the money and want a PSU that is stable and more than capable of providing you the power you need, look into PC Power and Cooling. They are, in mine and many other's opinions, the best PSU's you can buy. They are rock solid, provide a tremendous amount of ripple-free current, are efficient, and are capable of giving far more than their advertised wattage ratings (my 510SLI has pushed more than 600W without flinching). YMMV.

Rail amperages are not additive, you can't take 15A and 15A and add them together. It'd be a good idea to upgrade your PSU.

What's worse, some PSU makers list neither the maximum combined +12V amperage nor the maximum combined +12V wattage. In this particular case (with Fortron units), a good ballpark rating is to add up the amperages of the two +12V rails (15A + 15A = 30A), then multiply that sum (30A) by 0.8 (or 80%). This will result in a maximum combined +12V rating of 24A.
 
Hmmm, well I'm not sure if I'll even be keeping the PSU or the entire computer.... Someone bidded $1050 for it 0.o (same computer in my sig, no monitor just the computer itself). That and I have already saved money for it. If i this buyer actually goes through I will be a happy man lol.
