myVolts
A desktop power and reset switch with two USB 2.0 ports, audio and microphone jacks on a 1.2 m cable
The myVolts Desktop PC Switch Button extends the computer power and reset controls to the desk surface with a 1.2 metre cable. It adds two USB 2.0 ports, an audio output and a microphone input for convenient front-panel access. The compact unit measures 6 x 6 x 3 cm and weighs 170 g. It suits home, office or internet-cafe setups where the tower is out of reach.
The device draws power only for the LED indicator and the USB ports, so heat output and noise are negligible in normal use. No fan or active cooling is present. Power consumption scales with whatever peripherals are plugged into the two USB 2.0 sockets. The switch itself adds no measurable thermal load to the system.
The package includes only the switch button unit with its integrated 1.2 m cable; no driver disc, software or mounting hardware is supplied. Audio and microphone ports require correct header connection on the motherboard to function. The USB 2.0 ports work immediately once the internal header is attached. No configuration utility is needed or provided.

Plug the two-pin power-switch header onto the motherboard's PWR_SW pins and the reset header onto the RST_SW pins, matching the positive and negative markings on each connector.
Keep the ports free of dust and avoid yanking cables; if a USB port stops recognising devices or the audio jack crackles, the internal header cables can be reseated or the whole switch unit replaced.
The mechanical life of the push buttons is the first wear point; repeated pressing will eventually degrade the contact springs before the 1.2 m cable or the USB 2.0 interfaces show any signal loss.
