I built my computer about a month and a half ago now and everything is working great, but I got a Power Supply with the wrong CPU Power Cable. The CPU Power Cable from the PSU is a 4-Pin and my motherboard accepts an 8-Pin, the motherboard is an EVGA nVidia nforce 750i. I called EVGA and they said to just plug in the 4-Pin and you will be fine, but you shouldn't overclock. I recently heard that you can get an adapter that enables you to turn one/two of your cables into another 4-Pin CPU Cable, but is my power supply strong enough to do this? It is a Thermaltake 500w Power Supply and I have it hooked up to an EVGA nVidia Geforce 260 GTX, an Intel Core 2 Duo E8500 3.16GHz CPU, and several fans. (Obvious other things like CD-Drive and HD) With all of those things attached is there enough power to plug in another 4-PIN CPU Power Cable into the motherboard and start overclocking or should I just leave it be?

This is my power supply in a link: http://www.newegg.com/Product/Product.aspx?Item=N82E168...

Thanks in advance.

Id leave it be, i despise those converters

Your e8500 should overclock ok with just for 4pin, the 8pin is usually required for Quad and better stability.

Some motherboards ship with a 4 pin blank in that socket. Some don't. Your motherboard manual should tell you where to plug in the 4 pin cable. Generally, the 4 pin cable goes into the 4 pins nearest the CPU. It should go in only one way.
