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
 
Solution
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...

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.

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$

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