Problem with my new PSU - Corsair 400W

[shadowww]

Hello everyone!
Will try to be short and concise about problem.
I bought and install PSU recently, few weeks ago.

Model: CMPSU-400CX

Problem: I everything connect and install correctly. But when I turn the PSU switch ON my front power LED starts to blink with around 2 seconds interval. In this state I can not turn on PC - power on button doesn't react at all. To fix this I have to turn PSU switch back off (then blinking of LED stops but after few more times - its not instant off) and then switch it back ON. And repeat procedure few more times until I do not get blinking of LED when PSU is switched ON.

This problem seems worsening over time (I mean, now after few weeks of using that PC and PSU) - I have to turn it on and off quite some times to get it at normal state so I can turn on PC.

So question is, is that known problem, is there anything I could do or should I go straight to the shop (Links, Croatia) where I bought PSU reporting problem and asking for new one (I have all papers of course...)?

Thanks for any assistance.

Can you test the system with a different PSU? Also, is your system stock or is it overclocked?

Was it a new psu to replace a broken one, as when my old cheap psu died it went out with a bang and took my old hard drive out with it?

I`d suggest you test it with different psu as well, you don`t wanna end up damaging other parts of the pc as well just incase something is actually wrong with the psu.
