It does this because during the POST the motherboard detects a problem with hardware and hits the reset button which causes the PSU to recycle and so the loop continues.

Remove all devices from the motherboard except one memory module and try powering up, if it still happens then either you have a problem with the motherboard, the CPU, or the RAM module.
