I found a dead HIPRO Psu in one of the many NetVista A40s I'm reworking that had Teapo and blown G-Luxons inside. (Another damn shortcut from Big Blue- Just Damn!) They're on the low voltage output side. Appear to be 2200uF 10V (G-Luxon) and 1000uF 10V (Teapo). These Psus are proprietary units to IBM. Sucks! I have a new HIPRO tower Psu from IBM repair parts that has the same shit in it. Though new it'll go one day.......

Hi folks,
I have a couple of IBM NetVista desktop computers from around 2000-2001. They have Universal Scientific Industrial (USI) Pro286i motherboards, 733MHz Pentium III processors, and a whole bunch of bad Teapo capacitors. One board has visibly bad and venting capacitors, while the other doesn't look too bad so far.
The board with venting caps works fine, while the good looking board occasionally refuses to power on unless it's left for about 30 seconds after connecting the power - even with a known good power supply. (I am however aware I'll need to check the PSU... -
Thought that it would be worth rescuing this one, but it's got one bulged Teapo that is in front of the big coil.
Would it be perfectly OK to replace this 4700uf SC (which currently measures 600uf and 1.2ohm ESR) 5V output cap with XYJ 3300uf? More specifically, was the original 4700uf Teapo cap overkill?
i also (inline) tested the 3300uf SC (which is parallel with a 2200uf SC cap, that is right next to it) on the 12V rail, and get a measurement of 5500uf and around 0.1 ohms ESR - So those caps look like they are still healthy? -
Back in 2020 i bought a (2nd hand) compact ATX psu to replace my current one. My PC case only fits very short ATX power supplies so i didn't really have the choice of buying a decent 80Plus unit. The current unit is a modded YoungYear unit that i made a thread about a while ago:
A "nice" YoungYear unit? - Badcaps
The "new" unit is a KDM-M6480 480W psu, the 480W number is a typical KDM bullshit claim of course, but the 24A rating on the 12V rail seemed reasonable and the "Active PFC" claim gave me a bit of hope that this was going to be decent-ish.... -
Normally, I never post repairs this quick after I do them, because… I am usually very slow.
But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...

PSU Recapping time!
This is the same HiPro model HP-P3017F3 PSU detailed here . Only created this thread to make the information easier to find… and to show the slightly different capacitors used in this second PSU.
