First of all, sorry for the large pictures..
Alright, opened it up and I am a bit shocked about build quality...
Spare (sharp) aluminium parts lyhing around in middle of the cables...

So I did some messuring, definately an issue with the PSU. I opened it up and and it was clear why it's not working...

I mean, really!?
Fixed the cable, no it's working... Actually things like that can be dangerous...
