PSU for Asus Direct CUII OC Gtx 660

I'm looking to upgrade my PSU because my current one doesn't seem to support my new GPU. After a few minutes of running a game my PC shuts off, it will sometimes restart with a power surge warning and other times it just powers off and wont power back on unless I kill the power to the motherboard then power on.

Also my PSU doesn't have a 6 pin PCI-e cable i have to use a 4 pin molex to 6 pin PCI-e connector. Could this be causing the problem?

What would be the cheapest PSU I can get that will support my setup? I have looked at some corsair PSU's but wouldn't really know where to start.

My specs are:

ATX P4 500W PSU (not sure of the make)
Asus M5A78L-M/USB3 Motherboard
AMD FX 6100 6-core black edition CPU
Asus Direct CUII OC Gtx 660

    This is a good PSU:

    and has Two PCI-E (6-pin / 8-pin) cables so it is compatible with your GTX 660.

    You wont need more than 500w unless you are thinking of overclocking or adding a second GPU.
