Perfect Size and Compatibility
These perfectly fit the 12v CPU output of an ATX PSU. The plastic is high quality. The pins themselves are very thin metal, and you have to be pretty careful when crimping them to the wire to make sure it holds right. Overall, easy to use, helped me add some fan headers to an old system. Definitely good value for the price.

Great Quality at a Great Price
I ordered these connectors to use in some wiring in a 3D printer I'm rebuilding, and they're perfect for my needs. They work great on 22 AWG wire and fit the connectors on the boards I'm using perfectly. Crimping the pins onto the wires can be a bit finicky, but there are plenty of extras if you mess up. The pins fit securely into the connector body, making for a solid, durable plug.
