I have an xfx ts 550w power supply, I have a gigabyte ud3p 970a motherboard, an fx 8350 1 hard drive, and one ssd. I am on the final part of my build and I want to buy the r9 280 (' Please no other suggestions') and I want to know if my power supply can handle it all. My original plan was to buy the 270x but that was before the prices dropped so much. I'm not buying another power supply, I bought this one for $26 after rebate a month ago, I tested my system with my old video card, and it worked so I cable manged everything but I left the pci-e connectors hanging while I wait another week to get paid. I don't really care to hear about anything else
