New PSU crashes when playing games or running benchmark tests.

Today a received a new Corsair TX850M and a EVGA 4GB GTX770 in the mail. After installing both of the pieces of hardware my computer would boot up perfectly with no problem. I installed the latest nVidia drivers. Surfing the internet and doing non-graphic intensive tasks would work very well, but as soon as a launched Final Fantasy 14 I got a very low Frame Rate (average around 18fps) and then the whole system shut down.

I checked the cables connected to the graphic card to the PSU and they were connected fine so I rebooted thinking it might be a fluke. When I rebooted I checked MSI afterburner for gpu temps and ran kombuster. During the short time the benchmark ran the temp of the card never went about 47 and the gpu load never went above 86%, but within a minute of running it the system would shut down again. I'm assuming this is a PSU problem, but I have no idea why it's causing a shutdown, it has more than enough power to run my system. I can provide pictures of my setup if needed.

I took the card out, cleaned the pcie slot with canned air, and cleaned the card itself. When I rebooted and ran Kombuster again my computer crashed instantly. The gpu load and temps are very low and normal still.

The load during the Benchmark now reaches in the mid 80's

I already used display driver uninstaller and reinstalled the graphic drivers for the new card and that did not help. I will check the power connectors in the morning and get back.

I used different cables to power the Graphics Card and the same problem persisted. I decided to unistall the GTX770 and reinstall my old gtx 480 which I had never had a problem with in the past. After cleaning out the old drivers and reinstalling the 480 drivers the same crashing occurred while running any sort of graphic intensive app or benchmark. This further leads me to believe that the problem is the power supply. I may have screwed up the wiring for other parts (i.e fans, but those are running fine) but the graphic card wiring is absolutely fine.

i honestly think you may have got a faulty psu do you have another psu you can use in your setup, if the alternate psu works fine with the 480 then it is the psu and you should rma, the series you got is a reputable one and i recommend that psu but bad things do occur no matter how reliable a part is
