  • Thanks for the tips [USER="15329"]stj[/USER] and [USER="59111"]ChaosLegionnaire[/USER] - I may possibly run an ISA sound card in the rig so that's good to know.

    [USER="6996"]momaka[/USER] thoroughly enjoyed reading your post where you recapped and modified a similar PSU, very informative and I'm learning a lot (which is why i'm here) 😀

    I've compiled a list of what i've found so far in terms of replacements - i'm struggling with the 220uF and 470uF caps as there's only two options I can find, although i'm not sure if a voltage of 350v is...

  • Incredible information as always, thanks so much!

    I'll see if I can make an order (and collect) some caps from RS at some point this week before they close for Christmas. I've got a few things sat on the desk i'd like to recap now (and some other soldering work to do on a few other bits and bobs) so that would be a nice little project to keep me busy next week.

    Just need to find some time to sit down and research all the caps I need and get them ordered..! Will report back once i've got some caps 😀

  • A little update for you all, since I found a little time this evening to remove the caps on the output side.

    Firstly, I can confirm it does indeed have a 'PowerLogic' fan. It was pretty grim, i've given it a good clean and it feels smooth as silk. It was very quiet when I briefly tested the PSU as well, so i'll oil her up as suggested before that goes back in.

    Whilst I've got the PCB to hand, I thought it would be a good idea to share the model number for reference.

    MPT-98068-P
    Rev. A3

    Now, on to the caps. I've removed them and looked at...

  • Thanks all,

    Hopefully, ~200W will be enough for the rig I intend to build with this. I have a Supermicro P6DBE board with two Slot 1 350Mhz PII's ([url]https://theretroweb.com/motherboards/s/supermicro-p6dbe[/url]). I already own a 3dfx Voodoo 1, and a 3dfx Voodoo 3 3000 AGP, so I think picking up a couple of Voodoo 2's and running them in SLI on this dual CPU board would be the ultimate retro build 😎

    I'm torn on whether to replace the rest of the caps, on visual inspection, I can't see any evidence of bulging or leakage and I don't have the means to test them. Looking...

  • Hi,

    Thanks for your replies, I really appreciate each and every one of them - very informative. Regarding the popped fuse, in my original post I forgot to mention. On one of the 'floppy' style power connectors, two of the conductors have been cut (it looks like something else had been hard wired in and snipped on removal). I can only imagine this was cut when the power supply was connected/on, causing a short.

    Power supply model is: Advance MPT-300 'Thermo-Control and Noise Killer' - 300W max.

    The caps appear to be 10x20mm. I guess I was just trying to figure...

  • Hi friends,

    I recently acquired an old PC power supply (along with several vintage motherboards from late 90s/early 2000s). The PSU was dead upon first test, but quickly identified the internal fuse had blown. I fixed that, re-tested and i'm pleased to report it seemed to work great after that - no obvious issues or reasons for the fuse to blow.

    Afterwards, I inspected the capacitors more closely and noticed one pair required replacement. They weren't in bad shape by any stretch of imagination, but one was slightly bulged, and I wanted to swap them out for good measure....

  • Hi fellow capacitor enthusiasts!

    New here, joined today after discovering this incredible resource. I haven't registered for a forum in many years, so that just goes to show how thrilled I was to find this place.

    I'm a software engineer by trade, however I've always had a keen interest in electronics since I was young and have been keenly repairing/learning as I go. I'm pretty good with a soldering iron, recently discovered flux (after years of soldering without it!), and have a digital scope on my wish list for Christmas from the big man!

    Located in the...
