Static is energy that you have in your body, due to atoms friction, and if you move your graphics card with naked hand without removing this current from your body, you may release a "spark" to the circuit that may cause dead of some components, normally this takes time to happen. it is good to always touch your computer case in a metallic part with the psu plugged in to remove your static before touching any electronic component.
if you connected the pci-e card correctly on 2 different motherboard with different psus over 400w and both did not work, the only thing you can assume is that the card is dead, may be static or no, i think you will need to change this graphics card.
depending on what you did, sometimes sweat on the board may cause a short circuit, it is good to do that kind of stuff with clean hands and avoid touching the sensible circuits. also it is good to use anti static gloves or bracelets if you don't know where you are touching.
it is very hard to see a component dead by static, but there is also the possibility that you have bought a dead card, try changing it, also what is the PSU full brand and model?
some generic psus can damage graphics card and other components while they are at full power, so better to see if that psu is really good before adding another video card there.
i don't think the power supply is less than what he needs, but there may be a problem with the psu... but since he tested the video card in another computer and same problem happened i don't think the psu is with the problem, sincerely i never heard of that psu, and i don't know how it behaves, so if you can change it would be good too, but by the looks and the 80+gold i think it is a good psu;
I don't think the warranty will be voided if you didn't dissassembly nothing, and never had it running... better to return it soon as possible and ask for a new one.
hey guys, just thought I'd say that I'm currently running this card, and about two weeks ago I had a 400W psu and this gpu ran fine and I had more power consuming things. Also whats your old video card?
some good 400w psus can handle 550w or more, and some bad 400w psu will not go over 300w, so just saying you were using a 400w psu is not much.
But i also think his psu is enough because of the 80 plus gold certified, on the other hand, i can be that hi was luck to get a defective psu, who knows... but anywais he will need to change the video card since he tested it in another computer and same problem happened.
trust me, mine wasn't the best and I've seen the amount of power mine used to use it was about 400W so I was quite lucky. Maybe he accidently bent the cards pins? I've heard of it happen before and it being a nightmare to find out what the prob was
