I have an 850W PSU...and I have my drives split across rails. My drives are raided and the problem I have is that on boot, about 25-45% of the time one drive will be missing, so I have to reboot again, hoping that it appears and rebuild my RAID. It's quite annoying. I don't think it's a montherboard issue since the Windows drive never seems to be missing when Windows boots.... .... ....
