130W for 4 hard drives, a CD/DVD-RW, a Zip 100 and an AMD 900 (wasn't that back when they ran pretty hot?) doesn't seem an awful lot. Is this a typo?
I was about to say the same thing.
Many BIOS's will tell you the supply voltage; the 5V line is the most critical and must be over 5v (5.1 is typical); anything around 5.0 or below will cause problems. 12v is less critical in my experience but should obviously still be around 12v.
If in doubt a multimeter will tell you roughly what's going on. Also, try a decent power supply; it's always worth having one you can trust to test against.
But at 130W I'd expect problems, to be honest.
