I was setting up my pc in my room n I pushed it too hard against the desk and when it hit the desk it just suddenly powered off and died. I tried to power on again but it wouldnt.

I tried replugging all the main power cables and the cable for the front panel power switch, nothing.

I took the psu out and tried to power it on using a staple (I didnt have paper clips) and it did nothing. So, im thinking the psu is dead. But I've only had it for around 4 weeks so I'm very confused.
