I just built this as my first PC build. When I plug it in, it turns on for a few seconds and then turns back off. It repeats this process so I un-plug it. I try powering just the motherboard and CPU by un-plugging the usb, audio, and graphics card but it still happens.

System Specs:

PSU: Corsair 500W
CPU: Intel I5-4690K
GPU: Sapphire R7 260x
HDD: WD Blue 1TB
MB: Gigabyte B85M-D35 (Open Boxed)
RAM: G.Skill Ripjaws X 8GB
