Hi everyone!
Recently, I've decided to take a look inside my two old AT PSUs (see attached photos). The reasons for that were: (i) I blew up my NOS Startech PS2POWER230 AT PSU 🙁 (see my other post if interested: I blew up my AT PSU, is it worth to repair it?), (ii) I have still two other retro rigs that I want to resurrect (my 386 DX-40 and some 486). In other word I am short on AT PSUs and start thinking about refurbishing these two. They both still work, and only the first one (by EMITER) gives some buzz on the screen while connected (see photo below).
However, before starting my refurb-project, I hope for your opinion on these two PSUs. Are they look to be a decent quality PSUs? I notice that some parts of both boards are unpopulated, that may suggest cost-cutting. Is it therefore worth to refurb them? If so, recapping and changing fans should be enough, or should I replace some other parts as well? Maybe I should just give up on them and go with the ATX + ATXtoAT converter combo? What are your thoughts?
#1 EMITER PSU
Screen buzz due to the EMITER PSU (kind of a wavy vertical buzz)
#2 JNC PSU
