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.
