I recently built a PC with Dual PIII 1 Ghz processors. The customer requested a 300W power supply, so I built the machine and didn't think much about it. But the system came back the next day with a bad power supply (the system wouldn't even POST.) Do I need to install a higher wattage power supply, or was this probably just a bad unit to begin with? Or could it be another problem entirely? Any thoughts are appreciated.

The specs are:
Dual PIII 1 Ghz
ASUS CUV4X-D
2 GB ECC RAM
30 GB IBM HD
Floppy/CD-ROM
Creative Labs GeForce 2 256
Yamaha DS-XG Sound
D-Link 10/100 Ethernet
