I just rebuilt a Pentium III machine. I use my bench ATX power supply whenever I work on a system, and then I turn my attention to the build's PSU before integrating it. This is an Enlight HPC-250-101 as mentioned in the build quality pictorial thread here - https://www.badcaps.net/forum/showpo...postcount=1644, but it appears to be a different revision.
I have some interesting findings here. I have only tested with the tester. I have a scope, but I haven't use it with a PSU. I also don't own an ESR meter.
I know that the PSU tester is a bit of a "well, at least I've got something to use for testing" device - but the +12V reads 11.5 with basically/almost no load. -12V only showed LL. Adding a peripheral molex connector got 11 to show under the -12V (pic below). I don't know how trustworthy the PG is on this device. I will say that this power supply is basically an AT power supply with an ATX connector. -5V is available, and there is no on/off switch on the back.
My knee-jerk reaction upon seeing these numbers on the tester and the TEAPO and G-Luxon caps inside is "aah. whatever. Re-cap it."
What is more interesting is the glue. You can see instances of the glue starting to turn brown in places - check out the primary side as well as the coil in the center of "capacitor city" on the output side.
I am tempted to re-cap and DE-glue (and re-glue?). I would probably leave the two primary caps (Rubycon CE 470uf) but still remove the glue around them. What are your thoughts? Also - any other components worth replacing/upgrading? Tough to get numbers on the components - there is glue everywhere.
