What's the Difference Between the 1.8 m and 1.85 m Versions?
The 1.8 m version features a single-color blue LED. The 1.85 m version adds RGB seven-color lighting and a one-to-two splitter line, so both the external switch and the original chassis power button can be used simultaneously.

Frequently Asked Questions
Q: Will this external PC power switch work with my motherboard?
A: Yes — the switch uses the standard 4-pin Power SW and Power LED header connections found on virtually all desktop ATX and Micro-ATX motherboards. Simply match the wires to your board's Power SW, Power LED+, and Power LED− pins as described in your motherboard manual.
Q: Does this replace or disable my existing case power button?
A: The 1.8 m single-color model replaces the case button connection on the motherboard header. If you want to use both simultaneously, choose the 1.85 m version, which includes a one-to-two splitter so both the external switch and your original chassis button remain functional.

A: The switch features a built-in double-sided adhesive suction cup. Simply peel off the backing and press it firmly onto any smooth, clean desktop surface. It holds securely and can be removed and repositioned without leaving marks.
Q: What does the LED indicate?
A: The blue LED lights up when your PC is powered on, giving you a clear at-a-glance status indicator right on your desktop — ideal for setups where the PC tower is out of direct sight.
