One thing that might give a hint of a PS issue is to have the system idle, with machdep.cpu_idle_hlt=1 and run mbmon or healthd or similar, look at the voltages. Then do machdep.cpu_idle_hlt=0 and look at the voltages again. Add disk activity if you have enough disks to make a difference. If your voltages change, you have a problem. Many power supplies do not live up to their ratings. Pete > The Supermicro dual board I just purchased needed 400W minimum.
