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?
