Is 500W enough for a GTX 760?

Hardware PSU
1

I'm planning on buying a new GPU (Asus GTX 760 OC) and I'm wondering if I need a new PSU or not.

I currently have an 80+ certified 500W OCZ PSU. I do not plan on overclocking and I use one of the cheaper socket 1155 i5s on a Gigabyte mobo.

 

Will I have to get a new PSU or is 500W enough? And if it isn't what will happen?

It's enough.

Yup, more than enough, could probably handle two 760s, depending on the quality of your PSU.

500W is more than enough.

Gross overestimate.
