Teardown Lab – Arcade PSU
Before we use this PSU I think its a good opportunity to check that it is all sensible under the hood!

Yo, I just found the arcade manuals I bought for the cabinet. Do you want them? I think one is an original service manual for the North American variant while the other is a PDF printout for another region/variant.

there is a difference with the thermal pastes .. but in that use youd doing there would not be much difference .. but some are way more thermally conductive

You've got the knock-off one where I have the knock-off of the knock-off ;D
Mine's been ok to be fair. I did the same as you and checked it inside and out. As I put a mains fuse in I modified the board's crappy soldered in fuse (noticed yours has a clip mount – aren't we posh?) for that over-the-top switch I shared with you before.
I didn't like the shroud-less contact design either nor the "chocolate fire guard" grate they have on it. You can get proper guards for these but they cost more than half of what you pay for the PSU and don't appear to fit / mount these ones without a lot of modification. I cut some plastic to fit then used some decent thermal resistant electrical tape to create my own guard type bodge. Works fine and saves that being the cause of electrocution.

PS You've reminded me to replenish my heat-shrink supply 👍

That was a fuseable link you soldered over.

To avoid self-tapping screws stripping the threads, always, when replacing the screws, turn them anti-clockwise until you feel it drop into the existing thread. Then turn it clockwise to tighten. This makes sure you don’t cut another thread.

I once had a new Seasonic PC-PSU blew up into a blue power ball coming out of the back in the instant I switched on the power. No hardware got damaged, but since then I'm putting every power supply once under power before connecting anything to it. And I can't trust Seasonic anymore, although they are supposedly known for their quality. This was my first and last one from that company.

There was three progs near the bottom, where a trace looked like it could have been enhanced as well.
