There not particularly rumours....
I could have gone for that
PSU in my build but I dont really trust it, there isnt these kind of 'rumours' with a lot of other
PSU manufacturers.
Just do a search on forums.overclockers.co.uk and you will find plenty of info of failing Hiper PSUs.
Chances are you could be fine - but I wouldnt take the risk. I recommend if you can afford it getting a Corsair HX 520W
PSU, very stable and one of the best PSUs around at the moment, I think i heard somewhere they are based on the Seasonic M12 aswell which is very good - but more expensive.
