I'm wanting to throw a mATX botherboard into an HTPC case. The only thing holding me back is this:

The PSU pins are standard pin-outs on the board (same ATX connections). The problem is, the motherboard pins/connector is smaller than the standard ATX/PSU pin connector that I need to hook it up to (need this standard sized connector in order for the case VFD panel to work).

Are there adapters available for this (I don't need a 24-20 pin adapter, the connectors are already 24-pin - I need something to connect to that smaller mobo pinout). I want to leave the soldering mods as a last option, as I'm sure there must be an adapter for this somewhere.

If you need photos to compare the motherboard pinouts, I will post if needed.

Thanks if you can help!

so the PSU power plug is a 20+4 pin connector?? if you only need 20 of them, most will have a detachable +4 you do not have to plug in.

Some info on a 20-Pin PSU connector:

The motherboard takes the 24-pin connector? Then that part's done. Plug it in.

The VFD isn't off the ATX plug. It's usually off a Floppy type plug. It's just confusing when we read that the ATX plug is fine, it works, but then it's smaller and doesn't work.

Photo's of any type sure would help I think...

I've got a Thermaltake Mozart SX case, the VFD does too go off the ATX plug.

It's 24 pin on the mobo, but I'm saying its connectors are smaller.

I finally decided to dig out and dust off the cam to take a shot...

Left: Standard ATX connector to ATX motherboard. If I want to use the VFD I have to run the PSU pins into this, then run this into the motherboard.

Right: The 24 pinout arrangement that the smaller motherboard has. The pinouts are the exact same as the standard ATX, just smaller connector.

As you can see, I cannot "just plug it in". What to do? Any ideas?

(don't get confused about the wiring: the cables had to be flipped around so it would stay in place for the shot)

Geez, the one and only place that actually has them, I was looking everywhere but there :shock:

This should suffice.

Thanks a lot for that pointer!

Hmm yes looking at that again, it sort of does appear to be the same size on both ends, now (I don't have depth perception, hard to tell)...
So it looks like I'm still looking for an adapter; though I thought I had it for a moment. What I need is that same type (small male) into the mobo, but female (standard ATX) on the other end for PSU+VFD.

Worst comes to it (only if absolutely necessary) I could always find someone to solder the connections right?

thats one possibility.

another one (maybe) is the actual pins in the connector are removable, they slide out with a special tool. if the actual pins are the same size you just swap the shells.

What motherboard is this? matx should have the same sized connector as atx, i'm guessing you have an old board from like dell or gateway you are trying to use?

The motherboard is an Irvine-GL6E, made for HP. It's using 1-2 year old hardware, so it's not too old :P
