Well...'typical' 5V rail problems that started with the Abit KT7A-RAID I had at the time, then REALLY came out when I switched to the Epox 8K3A+ I have now. 5V readings that never went above 4.8V, instability, Hard drives powering on and off at random. All of these issues went away with an Antec 350W PSU (mind you the Enermax is a 435W PSU). Just for further testing, I popped the Enermax in my fileserver and mysteriously drives started becoming corrupt, disappearing or just powering on and off. Remove the 435W Enermax and replace it with a no-name/generic 300W PSU and everything worked again.
The vendor says they won't RMA it because they don't deal wth Enermax, but rather a distributor and the distributor won't reimburse them...or something like that.
Just got an e-mail from Enermax and they said to deal with the vendor OR if that isn't possible, then to get in contact with Maxpoint and deal with them. Waiting for an e-mail from them.
