I've got a bunch of the small HP Vectra PSUs, from the P1 through the P3 varieties. About half the size of a normal PSU, so not common. PM if interested and need specifics.

I'm curious as to what these look like (size, capacity)? HP Vectra PSU seem to come in a lot of shapes and sizes ...

Did you ever figure out: https://forum.vcfed.org/index.php?threads/hp-psu-fan-control-lines.25164/

Yes, I did--turns out that it's connected to an on-board thermistor. I found that I was able to control the PSU fan with a simple pot across the connector lines. I'll get some dimensions. The P1 is a little interesting in that it's not an ATX type and has a separate connector for the +3.3v supply.

These are all unusual in dimensions and probably difficult to replace.
I also have a couple of the old large AT (5170 style) power supplies; function unknown, but can check. Would not be surprised if recapping was needed, given the age.

Also a few of the older standard ATX style without the +12V CPU connector and 20 pin main connector. Power ratings vary from 200, 250 and 300W.

I have a Vectra VL in storage so if these are still available by the time I get to look at it, I'll post back whether any of yours are a match

Thank you. So these are all "bricks" but a bit odd in dimension. Not the later/other (non-Vectra?) HP styles with the weird shapes.

I pretty much stuck with Vectras, right down to the C10. Just seemed to be a bit better constructed than the usual HP "home pc" stuff. Speaking of oddball, I do have a Compaq 460W PSU for the Compaq XW6000 workstation. Bigger than ATX--BTX perhaps. Has the usual 24 pin power connector but with totally different pinout. (I documented that some months ago).

I still have the vectra VL cases with more modern (AM3) motherboards. I managed to fit appropriate TFX PSUs in to provide the necessary power; it's not a perfect fit but good enough. The original HP Vectra PSUs are nobody's standard. Of course, number 1 is the real oddball, with a separate 3.3V plug. I hung onto the cases because they would fit a standard ATX motherboard and are the usual HP old-style beefy steel desktop (not minitower) cases. Gives me somewhere to put my coffee...
