How to know if Power Supply is okay?

The computer doesn't power on. It only shows a solid green light in LED#1

The power supply makes tick noises and the noises change when I press the power button.

I would like to know how can I test it with a multimeter? I'm planning on buying a new MB because this one has a blown part but I don't want to buy a new MB and have a bad PSU kill it.

Here is a video to check out the sounds and the burned part: https://www.youtube.com/watch?v=LK7_qJPd...

A ticking noise is a coil or transformer in the power supply.

I would first replace the power supply before trying a new logic board.

I will record a video of the sound and post it on YouTube. I'll post the link here. Give me about an hour or two.

@pigoath - No need, I've had a few tickers across my bench ;-}

I will be uploading the video anyways. I would really appreciate if you could check it out. I want to know how to test the PSU with a multimeter to know if it's giving me proper voltage or if the problem is the MB.

By the way, is it normal for a PSU to make ticking sounds? I guess not?

No, the power supply doesn't tick! You have a bad coil or transformer within the power supply assembly.
