Hey Dominik,
I've got to say I'm having a nightmare with my PSU. I posted earlier in this thread about my 1300 G2 blowing up? Well, after a fortnight I received a replacement unit (without any cables, kettle lead, just the bare PSU). It wasn't cross shipped (as promised on your website, nor did I receive my t-shirt as an apology, also on your site).
After installing it into the PC, the replacement is also Dead! My old Enermax Evo works perfectly when I put that back in. I've tried different kettle leads, checked it's connected properly etc and it's not even lighting up the motherboard.
As I've received no new cables or leads with it I can't check to see if they are to blame either. When talking to your support dept I've been told that it must have been ok when it left as they are checked and that i'll have to start another RMA from scratch.
I'm not happy at all to be honest. Another fortnight without the PSU and more hassle shipping to Germany.
