I had a hiper 580w type R and went with an enermax liberty 620w for 'safety' and reassurance when overclocking my old opty 170 (the hiper was fine btw and coped easily). Sadly the enermax popped within 2 months taking my whole rig with it - seems trust is a hard thing to come by these days. With hindsight I wish I had stayed with the hiper. Just because a few people report it as being faulty and give horror stories about it dosn't make every one of them dodgy, you could be like me and buy a reputable brand and have that die on you instead!
