Video Card Dead, PSU at fault?

So I was mid playing FFXIV, and all of a sudden my computer screen went black and then it shut down. As I proceeded to turn it back on, my screen just said lost connection, check source/power etc... I just recently changed my power supply and started to think if my power supply was bad so I proceeded to open it and check everything in the system. Seemed fine, so I went through these following checks

1) Reseat the Graphic Card
2) Switch the hdmi cable and try different port
3) Switch the power supply
4) change the pci express lane
5) check if it booted if removed graphic card
6) switch the graphic card

Normally I would come to a conclusion that the card is dead, but the weird part is, when I plug in the 670 and boot it up, it shows the bios and then goes to windows starting but then loses connection. If I try to access bios before window starting, it loses connection. The power seems to be fine, since both lights are green, and nothing smells burnt anywhere. So is this a dead card? Or is there something I haven't tried?

Also I found a thread which kinda sounds similar to what happened with me except his video card was fine. Think it could've been related? Same model PSU too. Filing a damage claim with Corsair atm but not sure how it will go considering I didn't smell anything burning when I checked it.

More about video card dead psu fault
  1. Bios runs on default VGA drivers that are 2d but windows on the card manufacturers 3d drivers so looks like the card is a at fault. It is hard to say that the PSU since it would simply die itself without killing the card and still no display swapping the PSU.

    Well I know the graphic card is dead. I just think that the possibility that it was the Power Supplies fault that the card is dead is viable. Else wise it must've been really weird timing for my graphic card to die the instant I put a new power supply in.

    It can be coincidence but can be the PSU's fault. That PSU has all the internal protection so it should not happen but everything can be broken.
