Fujitsu ATX Motherboard connector, proprietary format?
Discussion
Work was selling some of the oldish computers, so got one of the little Fujitsu desktops, Core i3, DDR3 6GB RAM etc. probably can't match my Althon X2 6000+ for processing power but ought to be more efficient. Anyway, I'm moving the internals from the small Fujitsu case to my fancy large Antec case, which seemed okay apart from the motherboard power supply connector...
Firstly, it's 16-pin, rather than 20/24-pin. This is the connector for the Fujitsu
And comparison with the 20 pin connector from my Antec PSU
Now... while the 16 leftmost pins on my PSU matches that of the Fujitsu connector (both the shape of the connectors and location of the missing pin - so it fits the motherboard albeit with 4 pins hanging off), the voltages from the Fujitsu's connector, taking the rightmost pin as ground, seems to be all -12V asides from the pin to the immediate left of ground, which is -5V, while the standard ATX connector has a mix of voltages/grounds for each pin.
Would I be correct in thinking that the Fujitsu has some weird PSU connector format (I noticed the SATA power comes out the motherboard from another connector, rather than from the Fujitsu PSU directly), and that trying to connect the Antec PSU up and trying to power it up would be a really bad idea?

Did consider that, although I'd ideally want some official reference, or at least someone whos tried it before.
Only things I could find online were these, second link seems to go with something similar to your idea but not sure if it worked or not.

Think I'll just stick it back in it's original case, was hoping to stick in a 3TB drive for NAS/backups etc. but think I'll just have to find a way of attaching it to my Raspberry Pi.

Can't you get the motherboard reference manual from the Fujitsu TS web site? I bought a cheapo C2D machine earlier in the year as a replacement for my now 10-year-old desktop PC, and you can just enter the machine serial number to get to the various BIOS and motherboard references. http://support.ts.fujitsu.com/index.asp?lng=en
That said, my mainboard ref doesn't give power connector pinouts, but then mine might be more standard.
Cheers, I'll check that out later on There's a few odd serial numbers here and there but none seem to stand out.That said, my mainboard ref doesn't give power connector pinouts, but then mine might be more standard.

Isn't the Fujitsu connector the standard AMD connector? I have vague memories from building my AMD machine that the connector from the PSU doesn't use all the pins and hangs off the end a bit.
Think it's the Intel motherboards that use all the pins, could this be it?
No idea, it's an Intel board I've got though, quick google online doesn't seem to throw anything up about a 16 pin AMD connector. Could have 24 pin PSU connector into a 20 pin on your AMD machine?Think it's the Intel motherboards that use all the pins, could this be it?

Nice one, found this (it's a 'D3171')http://support.ts.fujitsu.com/Download/ShowDescrip...
However, it states " not supported by standard Power Supplies" and doesn't give any details of the pinouts looks like I'm stuck unless I'm willing to hack together a connector. I'll just use the original case, no big deal.
Might need to get a low profile graphics card though...

This page ( http://www.sp-it.net/index.php/articles/257-mainbo... ) suggests that it's a 12v-only motherboard, which might imply that it uses the 16-pin connector on Wikipedia ( http://en.wikipedia.org/wiki/Power_supply_unit_%28... ) :
Bah, missed that bit when skimming over the PSU wikipedia page earlier, clears it up then, cheers I ended up just using the Fujitsu case, including the original power supply with it's funny 16-pin connector.
FWIW despite it being a small case (low profile) I've had it running for a while with two hard drives and a GTX 750Ti graphics card - running for months at time with Folding @ home, playing GTA5, Skyrim and more recently the new Tomb Raider game. So the Fujitsu power supply is probably a bit over specified probably helps having a modest i3 processor which doesn't pump out much heat even when running under full load.
