My Power Supply Does Not Have A PCI-E Connector On It.

I'm buying the GTX 660 but that needs the PCI-E connector but the PSU doesn't have one. I don't really want to buy another PSU. Any Options?

Thanks

  1. they have atx to pci-e connectors in the box when you buy your gtx660. It would not be a problem and you'll see when you open the box nvidia will provide you with the necessary adapters. Make sure your PSU can handle the gfx card btw.

    That's not a good sign for your PSU.

    How many watts is your power supply? I would recommend getting a better PSU or risk frying your board and GPU.
  3. U will need about 650W BRANDED PSU, not generic crap.
    Usually those psu comes with the 2-6 6 pin connect cause they need to support crossfire/sli
    my psu ranking
    Seasonic(extinct in ca)->Antec(made by seasonic huhuhu)->corsair(anything except cx series)->evga. The rest brands arent top psu tiers.
    Generic psu are usually hit or miss. Most would do well at 40-50% of advertised load
    So if you would test your luck, go get a two 4pin to 6 pin connector at your local store or ebay, they come at around 3$

  4. watts doesn't tell you anything either. what is the exact PSU and model?
  5. GTX660? A good 500W+ PSU will suffice. Link in my sig.

    Toss your current one; chances are that it's not powerful enough.

    For a system using a single GeForce GTX 660 (non-Ti) graphics card NVIDIA specifies a minimum of a 450 Watt or greater system power supply that has a maximum combined +12 Volt continuous current rating of 24 Amps or greater and that has at least one 6-pin PCI Express supplementary power connector.

    An exception is the MSI GeForce GTX 660 HAWK 2 GB. It requires two 6-pin PCI Express supplementary power connectors.

    Total Power Supply Wattage is NOT the crucial factor in power supply selection!!! Sufficient Total Combined Continuous Power/Current Available on the +12V Rail(s) is the most critical factor.

    A Seasonic G-360 (SSR-360GP Active PFC F3) is sufficient to do the job.
