PCIe x1 Dual PS/2 Expansion Card, PCI Express PS2 Keyboard & Mouse Controller Card with No USB Circuit, SATA 15-Pin Power Supply, for Industrial PC, POS, Server KVM & Legacy Devices

This PCIe to PS/2 expansion card solves the pain point that new motherboards cancel native PS/2 round ports, allowing you to continue using traditional PS2 keyboards, industrial mice, cash register peripherals and server KVM equipment. The board adopts exclusive PS2 signal wiring without integrated USB circuit, eliminating cross-talk interference between USB and PS2 signals for more stable long-term operation.

It comes with two color-marked dedicated PS2 ports, keyboard and mouse work independently without mutual conflict. The reserved SATA power input supplements sufficient power from the computer power supply, effectively solving insufficient power supply issues of ordinary PCIe PS2 cards that only rely on PCIe slot power, which easily cause device dropouts under continuous heavy load.

The built-in professional main control chip processes input signals independently, occupying almost no system resources and realizing instant sensitive input feedback. It widely matches industrial control hosts, laboratory test equipment, financial POS machines and server room KVM management hosts that must use PS2 interfaces.

All port contacts are gold-plated to reduce signal attenuation and anti-oxidation, extending service life after frequent plugging and unplugging. It supports hot swapping of qualified PS2 peripherals, easy to install: insert into empty PCIe slot, connect SATA power cord, install the matching driver and restart the computer to take effect.
