Odd request but my 280x Toxic GPU decided to stop displaying and need to test my PC.

Have sent the card away and was sent back cause when tested by them it worked with no issues. Have tried everything (in my knowledge) to test and possibly find another fault, and only thing left is to try another PSU and/or same range GFX card (which I don't have spares of).

My old 560TI works fine in my PC so..doubted that it was anything else in the PC but obviously if it was working while tested, then the issue is with me. Trying to decide if I should buy a new PSU or not but it's pretty pricey and would hate to buy one and find it wasn't the issue.

Would need a quality 650w or up with the ability to supply at least 30A to the card.

Understand that I'm kinda a newbie on GZ so happy to bring my PC over to you and test it on the spot or whatnot if you're worried.
Also would be happy to test my 280x in your system just to see if it gets picture if that's preferred (providing you have enough power - don't wanna blow up your PSU :L )

Would appreciate any help~! >_<
