Resurrecting this thread instead of making a new one, got a few questions.
I inspected the PSUs at the time of the last post and didn't see any visible issues with the caps. Since then, the Compaq has begun to develop a dull but very high pitch whine that I haven't yet pinpointed from where it's coming. Decided to do another inspection of both systems and get some photos / videos this time. Would anyone be so kind as to glance over what I took? To me, everything still looks good, but I understand looks can be deceiving. Photos and videos can be found at this Dropbox link here.
Also, I've got a new EVGA 650 B5 that has good amperage on all rails for my ATX builds, but no -5V rail. I was considering using an ATX-to-AT adapter and transplanting it into the Packard Bell just to play it safe, but since that PSU has a -5V rail, I'm concerned about doing damage. I'm not familiar with what all utilizes -5V rails or even what happens if there's a lack of voltage on said rail in the presence of such devices. Would there be a risk / would there even be any such devices in that rig? See sig for details - it's the PB M.
Lastly, I've been slowly practicing basic soldering over the past five years (recapping an LCD mainboard, etc. - nothing to do with a PSU) and am planning to invest in a proper solder station, hot air station, preheater, etc. so that I can maintain my stuff over the coming years. In cases like my Packard Bell and Compaq, where the former has that -5V rail and the latter has a proprietary form-factor, would it make more sense to recap the OEM PSUs than to try installing new ones?
