bombledmonk...Duro power supplies in my opinion arent the the worst Power supplies out there but also not the greatest...I've had one that was good...good specs and worked fine...the next one was VERY poor...way off specs, caused power-up problems and eventually died...
They are iffy at best.

Urban_Squrill...... have you used Aida 32 or something similar to check what your voltages are actually running?
You may be surorised at how far they are off.
Ive teated 3 of those "Power Magic/By Xcase" PSU's and they have all been way off. Just something to check...
