Vszerda 2-Pin Power Switch Cable 20" 2 Pack

Replacement power-switch cable

The Vszerda 2-Pin Power Switch Cable connects directly to a motherboard’s 2-pin Power SW header and acts as a momentary on/off or reset button. Each pack contains two cables, making it convenient for a primary build and a spare or test bench. No soldering is needed; the connectors press onto the header pins for a secure fit. The 20-inch length gives enough reach for most case layouts or open-air test setups.

Thermals noise and power

This cable carries only a low-voltage switching signal, so it generates no measurable heat and draws negligible current from the motherboard. There are no active components, fans or electronics that could produce audible noise during normal operation. The wiring is fully passive and does not affect system thermals or power consumption in any way. Installation adds no load to the power supply or voltage regulators.

Behaviour under sustained load

Because the cable is a simple momentary-contact switch, its behaviour does not change no matter how long the system runs under heavy load. The contacts remain stable whether the button is pressed once a day or repeatedly during extended troubleshooting sessions. No thermal throttling, signal degradation or latency increase occurs over time. The mechanical switch rating is unchanged by continuous system operation.
