Likely power surge required new PSU. Now graphics card doesnt work.

Using this build: http://pcpartpicker.com/p/MbGkP6

I bought a 600W corsair bronze PSU to replace the broken one.

The lights and fans turn on the graphics card. But 'display adapter' shows no evidence of card, nor can i get an image from the card. Only when i connect HDMI to the motherboard.

I manhandled the graphics card in frustration when dismantling the computer. There are no obvious physical defects.

I have tried a different PCI port. It is correctly connected.

So my question is: Whats my next step identifying the problem. Do i just have to shell out for a new one?
