PSU Issue ?

[craigmmmm]

I have a strange issue with my PC which I think may be the PSU ?

When I press the power button the pc will start to power up but 2 seconds later will switch off only to restart 2 seconds later and boot up ?

Anyone got any ideas ?

Thanks in advance

Craig

PSU is a Thermaltake ToughPower 1500W
