Looking for a second opinion on my PSU after upgrading video card.

I purchased an AMD R9 280X today to upgrade my PC. My PSU is a Seasonic S12II 520w I purchased at the same time as my last video card(Radeon 6870). I also have an AMD 8320 with a slight overclock to 4ghz, an SSD and HDD, nothing too crazy. I know it would be pushing my power supply just about to the limit, but if possible I would like to not upgrade it. So I was just hoping for some input from some better informed people before I get my video card in so I can order a new power supply if needed. Thanks.

    Hi - You are fine - your system should have at least 30 +12v rail(s) amps, your PSU has 40 +12v amps,
    allowing you plenty of headroom for OC, etc.
