I mean, you don't even have to go Chinese to find reasonably priced but reliable good capacitors. There are Koeran brands like Samyoung, Samwha etc. that I don't mind using for any of my repair jobs..

It's not like Japanese caps are that expensive either, unless you are buying them in small quantities from Digikey. Prices for small quantities are there often more than three times what you would pay per piece if you were buying them by the thousands. LCSC is a much more affordable place to buy a small number of caps.

Greetings. I just want to thank and congratulate everyone involved in this highly interesting and informative thread. Kudos to you gentlemen!

Hi Momaka!

Regarding the use of modern PSUs with DC-DC for the minor rails on classic "+5V heavy" retrocomps ...

What if we DIY attach heatsinks to the OEM naked FETs ...

^ Before.

^ After (crude photoshop just to get the idea).

And rig or swap the PSU fan to make sure it will always blow a healthy amount of cooling air on them?

The QM3054M FETs in the pic are rated (provided proper heatsinking) @ 97A .
