I have a amd 64x2 3800 a 7900gt 2 7200 rpm hard drives a cd burner, a dvd burner, a memory card reader. I overclocked my cpu to 2.44ghz and my card to 540mhz and memory to 1600mhz. My computer came with a generic 300w power supply, from what I hear I might want to upgrade. Any suggestions?

I have used a FSP Group epsilon PSU for awhile, and it is a damned good one. A Epsilon is probably overkill for you, so check out a generic FSP Group on newegg, they have some good deals. Seasonic is also another good choice.

NewEgg has teh Antec TruePower 550 watt PSU for $89...
That is a good price for quality power...

btw this is my PC being powered by that PSU...

Measurements and Analysis of Power Draw consumed from this Opteron PC using Kill-a-Watt meter.
Based on a brief quick test, and several follow-ups, I preclude that my AMD Opteron rig when over-clocked at 2420MHz from 2200MHz consumes:
≤ 200 Watts at Idle
≤ 250 Watts during Boot Up
and
≤ 350 Watts at maximum load when benchmarking using 3DMark06 (at 75% efficiency, my PC is requiring ≈ 265 watts of true power from my power supply)
Note: This is only the PC measured at outlet from the Power Supply; my LCD Monitor was not measured per these results.
