It could very well also be your controller, by the way...I've only heard of a controller doing that once before (680i), but I supposed it could happen again.

Not much. I had a 750was PCpower running more then that at one time without a fuss. System is running so far, Primed for 12 hours without a problem but you never know.

I had all three harddrives on one of the single 3 prong outputs of the powersupply so maybe it was too much for that rail?...hmm..wonder how I could figure this out?
