PC External Power Button, Desktop ON/OFF Reset SW Splitter with HDD LED, Computer Motherboard External Power Switch Extension Cable

This PC external power button extension module is a practical accessory for computer hardware debugging and bare machine testing. It integrates power ON/OFF switch, reset switch and HDD activity indicator light, allowing users to control the startup and restart of the computer outside the chassis without installing the original case front panel.

The terminals follow standard motherboard front panel pin assignment. You can directly connect the cable plug to the motherboard F_PANEL header. The built-in HDD LED clearly displays hard disk read and write status in real time, helping you observe whether the storage device works normally during hardware testing.

With extended wire design, you can place the control button outside the test bench, cabinet or equipment rack. It greatly facilitates repeated testing of motherboards, CPUs, graphics cards and other hardware during maintenance and assembly.

Simple plug-and-play operation, no extra driver or power supply needed. Widely used for computer repair shops, DIY overclocking testing, industrial equipment integrated hosts and barebone workstation setup.

Important Reminder: Please check the positive and negative polarity of the LED pins during wiring. Wrong polarity will cause the hard disk indicator light to fail to light up. Do not short-circuit the pins to avoid motherboard damage.
