1300w Enough for 3x R9 290x?

[ImperialistMillitant]

Hello

If I was to Run 3x R9 290x's, would 1300w be sufficient? I plan to upgrade to X99 within a few months.
My PSU is a EVGA G2 1300w PSU. Running 6HDD's and 12 Fans with an i7 5820k.

I also used a PSU calculator and it came to 1350w.

Regards
..

RealHardTech recommend 1300W - so you'll be fine. The Supernovas are good PSUs
