micro fit atx power connector

Specs: xp, turion

hi all. i posted here a couple days ago about building a wooden case machine, and i got lucky: a friend of ming sold me his hp slimline machine for super cheap (cheaper than a decent via board), and it's itx!!! :D

but there was a catch, the power supply doesn't work. it will not power on its own and won't boot the machine. i need a new psu. problem is, i don't feel like spending hp's price on another pitiful 180watt psu. i have a good spare psu right here, but the atx connector is different!


i need a converter (not that good at splicing wires). the small hp connector is called a micro-fit atx connector, and the standard one is a mini-fit. the pinout is the same, and are both made by molex, but i can't find anything on their site.

i need a converter for micro-fit atx 24 pin to standard atx 24 pin. help!

Right you are if you think you are

The picture shows a 20-pin and a 24-pin connector, not two 24-pin. So you may need to clear that up first.

There are adapters for 20-to-24 and 24-to-20 conversion but I'm not sure one would work for you as the plastic around the pins appears to be shaped differently.

You can check my #2 here for links to those generic adapters:


Again, that may not be what you need.

this picture is off of some website. i actually have a 24 pin atx power supply here, but the atx connector on this motherboard is the same size as the smaller one in this picture. damn. knew i should've cleared that up

OK, you've got a 24-pin 'mini fit' from the good power supply but your motherboard needs a 24-pin 'micro fit'. So the adapters I mentioned aren't going to work.

I looked at the other adapters on that site and couldn't find what you needed. If someone knows of one hopefully they'll post the link. Otherwise the only alternative may be to cut the wires and swap the connectors.
