Already touched upon how in another review: The ATX plug did not fit on the motherboard, somewhere stuck a mechanical resistance. The PCI-E cable has, interestingly, a "false" plug so that it does not fit into the really excellent for PCI-E connector on the PSU. Because of these teething problems, I can not say anything about the operation, because I did not come so far.
So rather play it safe and take up a similar power supply other brand.
