Help identifying a (proprietary?) PSU fan connector

Help identifying a (proprietary?) PSU fan connector - Lemmy.world

I’m trying to replace the jet engine fan inside the PSU of a Nu 1.1 [https://segaretro.org/Nu_1.1] with a Noctua equivalent and am having trouble identifying the connector. The PSU is a Delta Electronics Model EDPS-250AB A, Part Number 400-5494-91. I have taken several pictures of the fan connector and its header in the hopes of identifying the connection. I originally thought it was a JST-EH 2.0, but it is not, and the only means of comparison that I currently have. Photos here: https://imgur.com/a/JQVahV3 [https://imgur.com/a/JQVahV3] Please help!

See if you can swap the connector, those pins can be released if you gently lift the locking tabs and pull the wire away from the connector. The metal connectors from your replacement fan might not fit into the original, but it’s worth a try.

Thanks for this suggestion! Is there any chance of breaking the connector by doing this? I replied to another commenter, but to emphasize, I am only looking to modify the fan and connector as a last resort because of how rare this equipment is.

Breaking the plastic would be tough so long as you’re not hammering it. The connectors crimped to the wires it’s another issue and if you pull too hard you could get the wire to come off the connector if it isn’t soldered.
