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

submitted 1 year ago by [email protected] to c/[email protected]

I'm trying to replace the jet engine fan inside the PSU of a 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.

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.

Yes you could break the connector if you're not careful. However at the end of the day, it's not like you can't replace both sides of the connector with standard hardware, and at the very worst you could solder the fan to the pins and cover each wire with heat shrink.
