Need help with a PSU

[oakdad]

I just finished putting a computer together and it appears my PSU is to small according to the Bios monitoring software. I was have the following.

Tagan 480W PSU +3.3V@28A, +5V@48A, +12V@28A
MSI "K8N Neo2 Platinum" AMD Socket 939 CPU
AMD Socket 939 Athlon 64 FX-53
4 Sticks of Crucial Ballistix 512MB DDR PC3200 184-pin DIMM
Seagate 200GB 7200RPM Barracuda 7200.7 SATA Hard Drive
.3 amp Enermax Adjustable Speed 120mm Cooling fan
.14 amp Jamicon 120mm fan
.25 amp ZALMAN 80mm fan with Quiet Mode Adapter for CPU cooler
Thermaltake PIPE101 Model CL-P0006 for cpu cooler
Pioneer 108D 16X Dual Layer DVD+/-RW
MSI 6800GT graphic card
8 usb ports
2 1394 ports
On board audio
wireless mouse and keyboard

The Bios monitor software is telling me my I have the following. ~3.12v, ~5v, and ~11.68v. I have the exact same psu in my other computer and swapped it out and got the same results. So I am now in the market for a PSU that is larger than the 480w tagan and doesn't exceed 30dB any suggestions or ideas.

Unless you're having stability issues, I wouldn't worry too much. Although I could be wrong.

If you want to get a more accurate voltage reading, use a multimeter.

I hear Tagan is a good PSU brand anyways.

Measure the voltages with a multimeter first. Tagan is supposed to be good. You don't need more than a good 480W PSU, anyway. The only voltage I'd be really concerned about there is the 3.3V.... I'd hope you could adjust that power supply, but I don't know for sure.

Your best bet is to hope like hell the monitoring chip is way off as you reach for that multimeter but if you do get a new PSU, get a Fortron/Sparkle 530W
