Wife's pc psu died so i got a HX850 psu to replace it. However it would reboot after shuting down. Tested with a cheap £30 600w psu and it works. OCUK tested it in 2 systems and said it ok. So i now have a very expensive doorstop. Rant over.
if a 300 watt psu kept it happy, I would say that you paid for a very expensive psu to power a doorstop.
