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.

What's In the Box

• ATX Breakout Board with Status LEDs
• DuPont Jumper Cable Harness (8-pin) for direct target motherboard front-panel connection
• Connecting Cable to plug directly into the USBridge Screen Module

Key Features & Specs

• Complete Bare-Metal Power Control: Remote power-on, graceful shutdown, forced hard power-off, and hardware reset (Hard Reset).
• Optocoupler Hardware Isolation: Built-in optical isolation circuitry ensures strict galvanic separation, protecting your target motherboard and KVM host from ground loops or high-voltage spikes.
• Real-time Status Telemetry: Reads Power LED and HDD Activity LED signals directly from the motherboard front panel, providing live system status feedback inside the KVM interface.
• Universal Motherboard Support: Fully compatible with standard front-panel header pins on ATX, Micro-ATX, and Mini-ITX motherboards.
