PSU dead or is there a short?

[HeavensCloud]

I recently re-ran some cables behind my mobo tray and now I have zero power or lights on anything. Its an HX620 with the rig in my sig. There is no mobo light, no PS lights but I can't remember if the PS even had any power lights on it. The PS is plugged in and the outlet is good. I can't even get a flicker of life from any component. Any suggestions to diagnose or fix this?

Really hoping it's not my mobo.

I would start by checking connections. Make sure you 24-pin and 4-pin are plugged in properly. Also make sure they're no so tight that they are pulling on the socket they're plugged into. I would also check to see if any of the cords are running near sharp edges.

Ok I just connected green wire to all the grounds(black) and no response. What the hell Corsair.
