Hcg 520 doa

[Goobley]

I just purchased a new HCG 520, and a new case. I spent a while installing it into my case, plugged to power cord in, pressed the switch on the top and nothing happened. I checked the cables, they all looked fine and tried again. I changed the kettle lead in the hope of it being duff, no luck.
I then got my old corsair psu that I just took out, connected the 24pin, 8 in, GPU, and HDD. Hey presto it powered on first time. I turned off the old psu, disconnected it, and put the 520 back, once again, nothing, nada, zero, zilch. I did however notice that the led in my usb mouse was flashing (don't know if it of interest though).
I have also tried the paperclip test
Please advise as to the recommended course of action.
Thanks
Chris
