UC391 6-Pin Male Connector – Without Wire (Plug-Type DC / CPU Connector)

Description

The UC391 6-Pin Male Power Connector—widely recognized in the industry as the Molex Mini-Fit Jr. or standard ATX/PCIe 6-pin connector—is a highly durable plug designed for secure, high-current power distribution. Commonly utilized in Switched-Mode Power Supply (SMPS) units, PC motherboards, and industrial control boards, this connector guarantees stable electrical contact and reliable long-term performance.

Built with sturdy, heat-resistant plastic housing, this connector features standard "keying" (specific pin shapes) to prevent accidental mismating and ensure proper polarity. Because it comes without pre-attached wires, it offers complete flexibility for building custom wiring harnesses, doing hardware repairs, or creating bespoke DIY electronic assemblies, allowing you to crimp and use the exact wire gauge your project demands.

Frequently Asked Questions (FAQ)

Q: Does this connector come with the metal crimp terminals?
A: This listing is for the bare plastic connector housing only. You will need compatible metal crimp pins and a suitable crimping tool to secure your wires into the housing.

Q: Is this compatible with standard ATX CPU or PCIe graphics card power cables?
A: Yes, this footprint is heavily utilized in standard computer power supplies. However, always double-check the specific "keying" (the square vs. rounded shapes of the individual pin slots) of the component you are connecting to, as CPU and PCIe keys differ slightly to prevent cross-plugging.

Q: How do I assemble this?
A: Strip your wire, crimp the appropriate metal terminal onto the bare copper, and push the crimped terminal firmly into the back of the plastic housing until you feel it "click" and lock into place.
