My disk drives are rated to use 19.1 watts while active. My disk drives also get very hot without forced air movement. 14 such disks use 267.4 watts. That would give you 152.6 watts for everything else. I bet your disks use less power than mine. I agree with Michael, you may be exceeding the power rating of your power supply. Also, I would not want to push a power supply to the max rating. It should be sized 50 watts or more beyond what you need.

And yes, they are on a single 420w PSU along with the motherboard, Athlon XP 2600+. and 5 80mm fans. Not much else though. I'm working my way towards a 15 drive box now. Just waiting for the new enclosures to arrive. -- Brad /"\ Save the Forests \ / ASCII RIBBON CAMPAIGN Burn a Greenie.
