I have a 500W Antec Earthwatt PSU with a combined 408W max load on its two 12V rails.

I'm looking to run a Radeon HD 7950 and a GTX 760 for hashing (no, not cryptomining).
The 7950 draws 200W while the GTX 760 draws 170W.

Is my power supply enough to keep these cards running at 100% for several weeks at a time?

Thanks!
