I thought about this as well - I have an Enermax 450 in there right now... I'll have to look for 
a higher watt power supply next I guess.

Also look at how your feeds are balanced. Some PSUs have two rails, putting all drives on a single 
rail causes your load handling capacity to go down significantly. I recommend getting a single 
rail PSU as well, well above the capacity you think you need.

I made the move to a beefy single rail supply a few years ago. Wished I'd done it sooner.

I'm using two of these :

Both machines have 6 core Phenoms with 16GB of ram.
Machine A has 15 7200RPM drives
Machine B has 10 7200RPM and 4 15000RPM Drives

The power supplies are well within limits, run cool and I've not had an issue since I upgraded to 
them a couple of years ago.

I do staggered spin-ups on machine B, but Machine A fires all drives at boot. They've been running 
in this configuration for about 4 years on these PSU's.
