Hmmm...my mail filter must be malfunctioning... 8-)
Bryan is right. Your machine doesn't have nearly a large enough power
supply. Between the drives/processors/fans/fancy mood lighting/etc I'm
surprised that it even boots. As Bryan mentioned, PC Power and Cooling
(also my preferred vendor for power supplies) has what you need. The
turbocool 850SSI will probably solve your problem. PCPC tends to be
very conservative when rating their supplies unlike most of the bottom
feeder Taiwanese/Chinese suppliers (which is undoubtedly where the
supply in your supermicro case came from).
Also, if that machine is doing anything remotely important, do yourself
a favor and buy some spare drives now and run it in RAID5 with some hot
spares. You WILL lose drives. The Hitachi/IBM drives have reliability
issues. Going forward, I'd recommend you stick with the equivalent
Seagate parts if that's an option for you.
Cheers,
