MEIRIYFA External PC Power Button Extension Cable 2M Black

External Power Switch for Desktop Computers

The MEIRIYFA extension cable adds a remote power button with a two‑metre lead, letting you turn a desktop on or off without reaching the chassis. It connects to the motherboard front‑panel headers using a ten‑connector adapter that carries power switch, reset switch and both LED signals. The compact button unit weighs 30 g and measures 6.5 cm by 3 cm, so it sits unobtrusively on a desk or can be fixed with the supplied adhesive pads.

Replacing a Broken or Inaccessible Front‑Panel

This cable replaces a faulty case power button or solves the problem of a tower hidden under a desk, inside a cabinet or built into a custom water‑cooled chassis. The mechanical key‑switch is rated for five million actuations, giving a crisp click and long service life compared with standard membrane switches. Installation only requires plugging the labelled leads onto the motherboard pins and routing the cable through a rear opening, secured with the included ties.

Limits of the Front‑Panel Header Interface

Functionality depends entirely on the motherboard’s front‑panel pin layout; the adapter cannot add features the board does not expose, such as additional USB or audio ports. Cable length is fixed at two metres, so the button must remain within that radius of the chassis. The lightweight shielding is adequate for the low‑voltage signalling involved but offers no protection against high‑current power conductors.
