How are your measuring the voltage? If you are using the system, it might be that it is not correctly reading it. The best way is to use a meter to ensure that the voltage matches.
Are you sure that a 480w power supply is enough? You might have too high of a load still and that is drawing the voltage down. There could also be a problem with something such that it is taking too much power.

I am measuring the voltage with Asus Probe, a program that came with my Asus motherboard. I doubt that 480 is not enough. I have a 2.2 Athlon 64 and a GeForce 7800GS (AGP). 480 sounds like plenty to me, but I might be wrong.

Was it ever at 12v? It may be that it is just reporting it lower than it really is. You won't know that it is accurate unless you test it with a good voltage meter.
To see if your power supply is enough you need to add up the power requirements for all devices in the system, including disks and USB powered devices without external power.
Other might have a better idea if the power supply is enough based on just the names you mentioned.
