Psu problem or graphics card problem?

post #1 of 5
Thread Starter 
My brother bought a computer from the second hand store I work at which we intended to turn into a budget gaming computer (computer was bought used but for extremely cheap). It's a gateway, 6gb (i think?) of ram, some sandy bridge i5, 1tb hard drive and other stuff that doesent matter. It had a lowend graphics card in it (like a 6650 i think?) which I took out and a 300w power supply which I also removed. Anyways I installed the graphics card and the power supply (which i've done 100 times on my own computer and ones ive built for friends and family) and he played a game of dota2 no problem then went onto the internet and the computer made a very loud pop sound and he described it as a burning smell. And the computer shut itself off. He left it alone until the next day when I came to take a look at it.

Computer turned on but would turn off after a little bit (around 30 min) upon further investigation the fan on the graphics card was not spinning. But here's where it gets weird. I plugged his graphics card into my computer and the fan spun right up with no issues. HOWEVER I plugged in my GTX580 into his computer and the fans both worked. What could be at fault? The psu or the graphics card. Both are brand new. I'm really stumped. And who do I call about warranty service? The manufacturer or the place I bought the part from? I only bought it (and just received it yesterday) a week ago.

Was it that PSU you like or the 730 watts in the same series?

That's the power supply I bought for him that I installed.

Check all connections properly. Try putting the Radeon 6650 back in his mobo since your GTX 580 worked with his mobo.

I just did this morning (with the thermaltake psu) and the computer seems to be doing fine. I got him to run 4 instances of heaven benchmark and play some games for a bit and all seems normal so far.
