I just put my computer together using a m5a99fx pro 2.0 mobo, an fx8320 cpu, 2 geforce gtx970s, a corsair 600w psu, a seagate HD, and a kingston SSD. When i plug the power cable in, I get a green power light on the mobo, but when I turn the computer on, the red CPU light flashes, the fans briefly spin, and it cuts back off. Any thoughts?
