Gigabyte superb 550 enough for 7850 2g/gtx660

Hello,
i am wondering if my powersupply will handle a 7850 or a gtx 660

current running a 1035t x6 with a gts 450 ftw, with 6 gigs of ddr3 1333 and a 1tb harddrive

So you have a 550watts PSU right?
A 550watt PSU can handle both the cards, if it is a good PSU. If it is 80 plus certified you are good to go. If not you have to take a chance.

its actually a 450w branded with the 550w max power draw. i wanna upgrade my graphics card which is a gts 450 and i'm running at a 1680x1050 res. i just want to know whats the best i can hope for in an upgrade for my graphics as this is my backup computer and would like to obviously upgrade the graphics.

I think it should work then but better provide the PSU make and model number
