DIY 4-pin to 2-pin and 3-pin adapter

The iStarUSA DIY-K150-03 converts a single small 4-pin connector into one small 2-pin and two small 3-pin outputs. It is intended for builders who need to power additional fans or LED strips from an existing 4-pin header.

Mounts with 3M tape on any surface

A plastic holder on the adapter carries 3M adhesive tape so it can be fixed inside a chassis without screws. The splitter frees up the original 4-pin header while distributing power to three smaller connectors for fan or lighting devices.

Passive splitter for continuous operation

The adapter contains no active circuitry; it simply routes the 4-pin supply to the three output connectors. It behaves the same under sustained load as in a brief test, limited only by the current rating of the source header and the attached devices.
