XP motherboard - what is this power board?

Posted by LifeguardGlobal952@reddit | vintagecomputing | View on Reddit | 7 comments

I’m looking to replace the power board on my xp machine. Any ideas what this does or what I can purchase to replace?

Motherboard DG41RQ or DG41AN

Motherboard bios boots when power comes on.

Thanks in advance.

Running from DC. Note how it makes 3.3V rails and seems to be fed only by 12V.

That's an earlier equivalent of the picoPSU (google it! Might be usable as a replacement). Allows you to run a normal PC mainboard from a single voltage power supply.

I loved picoPSU for things like DIY NAS and similar no-fan, no noise machines.

Yeah, you can't run your gaming rig on a picoPSU, but for some applications they are great.

This is the correct answer. It's just a DC->DC power supply, probably 12v 3amp input.

Many small computers do not need a ton of power so they can use a laptop power brick or similar to power the PC and it simply needs a converter board like yours to get all the needed voltages for the motherboard and accessories. Boards like that are cheap on Ebay or elsewhere. The board probably can use a normal PSU if the case has room for one.
