I doubt it. Never heard of Huntkey PSUs, so they're probably junk. You could probably get away with it on a good 750w like a Corsair though.

I've never heard of huntkey before , I think it's not a good one and it doesn't provide 770 real WATS ! You need something well known like corsair , gigabyte ...etc . and get 800 WATS at least to be safe .
Good luck .
