GTX 670 And GTX 660Ti PSU Question

[DekuHD]

Hey, i'm wondering if i can either run a 660ti OC'd or a 670 OC'd on my current psu. I only have the cash to buy a graphics card, and not a psu, or at least a decent one.

Here's my specs, can anyone help me out?


CPU
Intel Core i7 950 @ 3.07GHz

RAM
6.00 GB Triple-Channel DDR3

Motherboard

Gigabyte Technology Co., Ltd. X58-USB3

Graphics

ATI Radeon HD 5770

PSU

500w Corsair


Thanks!

Yes EASY.

Cheers for the quick replay man, it's been bugging me all day. I thought everything was down to the cards wattage draw, as my current card takes 108w max, and it says a 670 takes 170w.

Thanks

What you want to consider is the PSUs +12v rail max wattage and Amperage rating. If you have the Corsair CX 500 PSU you have available 34amps and 408watts max on the +12v rail which will run any single GPU on the market.
Always use this site to find out if you're PSU will run it and remember the +12v rail watts and amps are what counts for the GPU. http://www.realhardtechx.com/index_archivos/Page447.htm
