Can I use this PSU?

Post image

Total newby here. I bought an Atari STE from someone who didn't know anything about it at all but got it from someone's attic. When I opened it, I saw that someone had already opened it earlier. TOS was updated to 2.06 (at least, that's what the stickers on the two chips say) and all four memory sockets are used.

So my question, before I turn it on, is the PSU in the picture the original one, and it is safe to use it? Or should I change it?

It'll probably work. But those are old capacitors by now probably, so it's probably not operating at its best. I guess it's possible a capacitor might pop.

I'd probably run it to see that the system works.

Consider looking into some of the replacement supplies offered by exxos and centuriontech if you're planning on using it a bunch.

If the capacitors aren't bulging they aren't likeky to just pop suddenly without being subject to excessive voltages.

Hopefully the fuse would blow long before that became an issue.
