5V ARGB extension cable for JST SM devices

This two-pack provides a 1-to-1 connection between a motherboard 5V 3-pin addressable RGB header and a device fitted with a JST SM 3-pin female connector. Each cable measures 11.8 inches, adding reach for strip lights or fans without changing the signal. The black sheath keeps the wiring tidy inside the case.

One-to-one mapping with 11.8-inch reach

A single motherboard header drives exactly one ARGB device per cable, so the pair supports two independent strips or fans. The 30 cm length bridges typical gaps between header and component, but it will not span full-tower distances or daisy-chain multiple devices. Builders needing longer runs or one-to-many splits must choose a different cable.

5V 3-pin addressable RGB header only

The cables accept only a +5V 3-pin digital addressable RGB motherboard header and will not work with 12V 4-pin non-addressable RGB headers. Connector B is a JST SM 3-pin female, so the attached LED strip or fan must present the matching male plug. No other voltage or pin layout is supported.

Questions about this item

Will the 5 V 3-pin female header on this cable fit the ARGB header on my older motherboard?

Yes, the cable connects to a standard +5 V 3-pin digital addressable RGB motherboard header and is not compatible with 12 V 4-pin RGB headers.

How can I confirm the ARGB extension is working after I plug it in?

The connected addressable RGB LED strips or ARGB fans should light up and respond to motherboard RGB software once the 5 V 3-pin and JST SM 3-pin ends are seated.

What comes in the 2-pack and do I need any extra connectors?

The pack includes two 11.8-inch 1-to-1 ARGB extension cables and two 3-pin male connectors; no additional parts are required for a single-source ARGB connection.
