have ordered a 750W power supply and there was a 780W power supply with me ^^ first time not bad but as the power supply is not been adequate for my purposes and then have it brought me NEN BeQuit. This power supply is spinning so so rum that did not get along with spikes and every now and then just shuts down and you're afraid to its hardware. PSU is jetz for test systems and try rum on the workbench
My advice = prefer to invest a little more and get something sensible
