    Visual inspection aka seeing if there are noticeably blown capacitors? Sorry I don't have any experience with testing

    Yes, just looking for Physical distress; even a slightly domed top is a bad sign.

    Alright I'll do that. Thank you very much. By any chance do you know how to test for voltages using the multimeter?

    You can test the voltages but it's really unlikely that there is something wrong. Same goes for checking caps, it's really unlikely that they have failed.

    I agree, but it is a little like the story of losing ones car keys at night... one looks under each street lamp, not because it is most likely to be there but because that is where one could most easily find it. If one already has a voltmeter it is a low cost, low effort, check; bit like the pilot who makes a quick visual before setting off.

    Concerning capacitors, I've seen so many fail that while you are probably right, I'd still check. I have a PC that had problems booting when I added a video card; turned out a capacitor in the power supply was gone and the extra load from the video card was enough to show the problem. Initially it was very natural for me to wrongly blame the video card.

    Hi, I replaced the old PSU with this one: SeaSonic - FOCUS Plus Gold 550 W. I Tested it out using the tool that came with the box. Unfortunately, the Motherbaord won't evens tart. Tried removing everything except the CPU, no response. What could be the case?

    How exactly do you try to turn on the computer when laid out like that? Do you short the case header pins or does your motherboard have a button for that?

    Sorry for being a little vague. I shorted the pins from the motherboard using a screw driver. I'll provide a photo:
