Recently I replaced fan in the PSU, The fan molex pressed the green pcb card and made it move.
My suspicion is either soldering got loose on powerplug or a component on that green PCB got damaged.

I have a soldering Iron + multimeter, I'm going to disassemble the PSU.

Now I need suggestions what to look for, can I make some multimeter measurements to figure out if a soldering is broken or some component on that PCB card?
From wall using the Black/Green power on Trick I get following:
Power OFF: 0.0watt, Power ON: around 0.6 - 0.7 watt, I live in Sweden and we have 230volt system here.

If a component is damaged my guess would be it's one of the ones on top right corner on this picture, this image is from jonnyguru review of this PSU:

These 2 images are on my PSU and show the molex fan.

i'd check for cracked solder joints all over the small board, but especially near that upper right corner and at the base where it connects to the main pcb.
 
Resolder the pins for the fan connector and the pins that attach the small PCB to the large PCB (resolder at both PCBs)
