That faulty capacitor looks like Teapo SEK. I see more of those in the rest of the PSU. Definitely replace them too.

Replace all of them, I usually get these units with bloated SB output caps, often also others.

Replace _ALL_ Caps that are not the main bulk caps.
ie every 5mm/6.3mm one, every one on the secondary side.

For that you might have to desolder either the primary or the secondary heatsink and components connected to it.
