    Minimum 550W or greater system power supply (with a minimum 12V current rating of 38A)*

    That is the important bit on the same link you provided.

    How old is your PSU? remember PSU's degrade overtime, so yours may not be delivering enough power because of this.

    Hmm, well it says minimum 450W on the side of the box. My PSU is 3 years old roughly. I did not know that they degraded over time, interesting!

    Good getting that card from novatech, they are a fantastic company in my experience. If a new psu is required I would consider getting one with more wattage than you need, so that if you decide to upgrade any components you know you have enough power.Just make sure you get a premium one, Ive been though five cheap ones this year.

    Is there any way i can check whether my PSU is the problem? Because i don't want to spend more money to find it does not solve the problem!

    It is not just watts ACE99, you also need make sure that your PSU is delivering enough/required ampage on the 12V rails. That card needs at least 38A. So please do check your PSU for that as well.

    The label on the side of your PSU has the stats on it. Look at the 12V+ rails(s) Amp ratings

    Am I the only one who thinks the OCZ 600w is fine for the 460?

    oh maybe i'm reading it wrong where should i be looking for these stats?
    I just assumed it was the PSU as it was working fine before and now it crashes and the PSU temp is about 92 degrees C
    Am i wrong?

    Uh, you have four 12v rails at 18 each.
    You did uninstall your NVIdia drivers first?

    Its not a big difference, but I think single rails are a lot better.
    Anyway, the 460 has two 6 pins right? Make sure they are from different rails, as each can only support 18.

    I wouldn't be jumping to conclusions immediately, ocz 600w isn't a bad powersupply. Someone else help me out here D:.

    As far as i can tell i only have 2 x 6pin from my PSU. How do i tell if they are from different rails one says "PCI-E1" and the other "PCI-E2" do the one and two mean they are from different rails?
    Just read a whole article on rails and one rail is better

    hmm, i don't think i did uninstall my old Nvidia drivers i just installed the new ones. Could this be whats causing the problem. I will uninstall all my nvidia drivers now and start again

    It can certainly cause issues, you should have uninstalled the drivers. Anyway, you can do it now, uninstall the old drivers, reboot and run Driver Sweeper (you can find it in Techspot download section) to eliminate any older nVidia files.

    Then install the latest WHQL nVidia driver.

    Ok i reinstalled the drivers after using driver sweeper and it still has the same problem as before. I also borrowed a power supply from a friend which vastly exceeds my own one as it is rated at 900W and has about 80A and i still have the same problem crashes during a game. (Have changed back to old PSU now)
    Could it be something to do with me now using a HDMI cable to connect to my monitor?

    If you are not playing games does the system stays stable?

    Please download OCCT, and thoroughly stress test your graphic card (including vRAM), just to ensure that you haven't gotten yourself a bad graphic card.
