External Desktop Power Switch

The XMSJSIY BU54 adds a panel-mounted mechanical push button to a desktop computer. It extends the motherboard power and reset functions to a convenient location using a 2M cable. The unit operates at 5 volts and draws 1 amps, targeting builders who want front-panel access without opening the case.

RGB Illumination and Dual Switch Headroom

A built-in seven-colour self-cycling LED provides constant status lighting that cannot be customised or disabled per colour. The splitter adapter lets the original front-panel button and the external switch work simultaneously. The plastic housing is rated IP00, so it offers no ingress protection and suits dry indoor use only.

Motherboard Header Constraints

The adapter is designed for 2.54 mm pitch, 9-pin F_PANEL headers; boards with different pin spacing or layouts will not mate directly. Installation requires matching POWER LED, POWER SW, HDD LED and RESET SW leads to the correct pins. No wireless, software or addressable-RGB control is provided.

Questions about this item

Will the BU54 external power switch work alongside my existing front-panel power button on a standard ATX motherboard?

Yes, the included 1-to-2 splitter adapter connects to the 2.54 mm spaced 9-pin F_PANEL header so both the original button and the BU54 operate simultaneously.

How can I verify the BU54 is functioning correctly after I connect it to the motherboard?

Press the power button — the system should start and the built-in RGB LEDs will cycle through seven colours automatically, confirming power and LED circuits are active.

What comes in the box with the BU54 and what must I source separately?

The package supplies the external switch unit with 2 m cable, a 1-to-2 splitter adapter, and double-sided adhesive pads for mounting; no additional parts are required for installation.
