## Description

# USBridge ATX Power Control Board

**USBridge ATX Power Control Board** is an external hardware expansion module designed for complete, out-of-band remote power management of the target PC or server at the motherboard header level.

It provides hardware-level Power On/Off, Hard Reset, and real-time Power/HDD LED status sensing directly through your USBridge KVM interface—allowing you to power cycle or recover a completely frozen server even during a total OS kernel panic.

> ⚠️ **IMPORTANT COMPATIBILITY NOTE:** 
> **Screen Module Required!** This ATX board routes its power and control signals directly through the 8-pin connector on the **USBridge Screen Module (Status Display)**. It will **NOT** function as a standalone accessory without the Screen Module installed on your board.
