Thanks, looks like Mini-fit Jr could be a match. Plugs look like this: https://www.dropbox.com/s/oieq24xtb6mtyb6/2014-05-28%2022.51.00.jpg Distance between pins is a li-i-itle more than 4mm, and they were used as internal power connections in (mostly) HP servers. I do not have an ATX supply handy to compare, but dimensions could be about the same. Those extended housings around the pins were because these particular parts were mounted on hot-pluggable modules, and slanted sides of housing were used to guide connectors together. I did not have a chance to rip out those opposite parts unfortunately, just got several excellent quality PSUs, radial and axial fans, etc. On 28 May 2014 14:22, Denny Esterline wrote: > I'm not sure.
