I currently have a HD 6870 with a 700W power supply and I plan on getting a R9 280X which adds on another 250W according to PCPartPicker, will I need to update my PSU to run both of the cards at once or is it fine?

I dont want any information on card compatibility since mining doesn't require SLI/Crossfire it's fine.

So this PSU is basically 525W?

Anyway, thanks for your help if you could recommend any that would be nice :)
