Something like pops, probably psu, (Update:Did i find the problem ?).

Hello, so yesterday when i was playing, my pc shut off with loud popping sound, and started normally again. Today i was watching video and it did the same thing, but twice about 1-2 seconds after it tried to restart, i turned my psu off as fast as possible, there was also burning smell, and then i recorded it. But pc still runs fine.
PSU : LEPA MX-F1 500W ATX

Get rid of it before something else burns up !!

It feels like something switches off to prevent maybe overvoltage, or something like that. May it be because my ram is in slot b1, or should it be in slot a1? And before i used to have problem with pc starting each time i moved it, but it feels like it got fixed when i removed my motherboard battery and put it back there.

PC specs are:
Motherboard: Asrock h170 pro4s
CPU: Intel I5 6500
GPU: MSI Radeon RX480 4Gb
RAM: Crucial 8GB DDR4-2400 UDIMM
Power supply: LEPA MX-F1 500W ATX

Should i try to record inside of the pc to see what might cause it ? And if so, should i record PSU or Motherboard side ?

I still think it's in the PSU, input side, there are no high voltages after that.

So I looked into PSU and it seems like i found the problem.

And under the PSU was like the cap of that part:

Can anyone tell me what electrical compounment is that ?
And what might have caused it.

It's electrolithic capacitor with the top blown off. There's an X etched on the top so it opens up easy and doesn't explode. Something like safety valve.
Do not use !!!
