Is this Power Suppy(PSU) Good?

yeah king win is a very good power supply company. also cosair is the best rated for their reputation but i have a king win 1000w and have been using it ever since works perfect. that power is good for gaming so if you plan to game yes its good. but crossfire might be to much for that power supply even sli if you using high end graphic card. if your gonna get high end make sure you get 1000w or greater supporting sli or crossfire. the 12 volt railing is what is important, cant give the graphic card what it needs then will not work to how you want it.
