hi guys,this is my first post and i wasn't sure where else to turn. i recently bought a new XFX AMD HD 7870 graphics card for my pc and it installed fine and everything and after about ten mins of gaming there was a loud crack and the pc turned off. When i turned it back on again, there was some sparks in the case and the whole house shorted. i do not know what to do, i have a (peak) 550W psu and a healthy fan that has worked for over a year with no problem. can anyone help? cheers, YarManYak ps. i have checked the capacitors and they are not blown and there is a strong smell of burning

If it actually says it was peak rated for 550 W it is a bad brand, and doesn't have the actual capacity to run a 7870. Peak ratings are deceptive marking, most units that can do 550 W peak can only do it for a few seconds and have continuous ratings closer to 450 W.

If something smells burnt, open up the case and use your noise to find what went, the upside of catastrophic electronic failures is that they are easy to sniff out, the downside is that they tend to be rather expensive.

Get the new psu, install, and you'll find out. That's all you can do unless you visibly see some blown capacitors or burnt chips on the card.
