With a new R9 280X arriving soon I think now is prime time to get that new PSU I've been in dire need of. It's been 5 or 6 years since I bought my most recent PSU. This poor Antect Earthwatts 650w PSU has been through 3 major overhauls and many thousands of hours of games over that time (I can promise MechWarrior Online accounts for a few thousand alone). I think now is the time to retire the best PSU I've ever had the pleasure of owning. So now we come to the good bits.
I originally was not expecting a new addition to my computing family so I had picked out a Corsair HX650. http://www.newegg.com/Product/Product.aspx?Item=N82E16817139012
But now I think I'll need a bit more oomph to push my overclocked CPU /and/ 2x R9 280Xs So I've altered the list to these 3 PSUs.
Seasonic S12G-750 http://www.newegg.com/Product/Product.aspx?Item=N82E16817151138
Seasonic G-750 SSR-750RM http://www.newegg.com/Product/Product.aspx?Item=N82E16817151132
Corsair HX750 http://www.newegg.com/Product/Product.aspx?Item=N82E16817139010
I've never owned a Seasonic PSU so I don't know their model scheme too well and I'm open to any other suggestions you guys have.
