Just want to double check:

- I am planning to add a Sapphire R9 280X Toxic to my desktop, Crossfire with my 7970 Vapor-X.
- PSU upgrade required (currently 650W)

QUESTION === Would SeaSonic X-850 be enough, with a good margin of adding two more 3TB HDD (around 20W each?). [Part list enclosed below]

Thanks a lot :)
