I think that give you like 15 Amps, not positive though. It's OK for a rig like that, but if you upgrade anything, especially the video card, you will need a new PSU to go with it.

Well ya, but if you aren't getting random reboots or the like, then your current PSU is good enough for your current needs. Now, if you play games and get system crashes, freezes, etc, then it's time for a new PSU.

The way it works: If +12V1 rail is equal to 20A and +12V2 rail equal to 20A and combined they give you a wattage of around 360, then that means 360/12 = 30A total for V1 and V2 rails.
