Solved

Bought new EVGA GTX 660 and it seems like it crashes PC when pushed.

I recently purchased a new EVGA GTX 660 and a new power OCX 600 watt power supply for my old Dell XPS 8000(don't have a ton of money to build a new system so buying what I can when I can)

Whenever I play a game 1 of 2 things happen. Either the PC crashes or the Nvidia drivers crash. Running GPU-Z I see temps are around 70 and TDP is between 70 -80%.

Not sure if it's the power supply or video card. Any help for the PC gaming noob would be greatly appreciated.

    OCZ is not famous for their quality PSUs, I only buy Seasonic, XFX, Corsair (except CX series) and Antec.

    edit: although your system with a GTX 660 should only need around 450W, so it is possible that either the PSU is garbage/faulty or the GPU could have issues. What cpu does your machine have? and how much RAM?
  2. you need to post the exact model. and specs
  3. looks like your problem is that you only have pci express 1.0 instead of 2.0 which would be a a serious bottle neck. not to mention the XPS 8000 model is a low profile version

    I know I know upgrading this old Dell might not have been the best idea but I'm on a budget.
    CPU a Core i5 750 @ 2.67Ghz and according to what GPU-Z is telling me it's PCI-E 2.0
    It has 8GB of ram.

    It's running Windows 8.1 but just to be sure that wasn't it I reverting back to Windows 7 but still had the same problem.

    To be honest I only with OCZ because it seemed like it decent reviews on newegg and it was modular. I went with the 600 because it had 25A and EVGA said the card required 450W with 24A.

    It's this power supply http://www.newegg.com/Product/Product.aspx?Item=N82E16817341016
