Auto Power-On Module for Desktop PCs & Servers (ATX PWR_SW Trigger, 5V Standby Detection) is a hardware-based solution designed to automatically start a computer system when AC power is restored. The module interfaces directly with the motherboard’s power switch (PWR_SW) header and simulates a momentary button press using the 5V standby (5VSB) rail, ensuring reliable boot without BIOS dependency.

Features:

1. Automatic Power-On via 5V Standby (5VSB) Detection
2. Simulates ATX Power Button (PWR_SW) Signal
3. Works Independently of BIOS Settings (No AC Recovery Required)
4. Microcontroller-Based Timing for Stable Trigger Pulse
5. Inline Installation with Existing Power Switch Cable
6. Ultra-Low Power Consumption (<20mA)
7. Compact PCB Design for Easy Integration Inside Cabinet
8. Reliable Operation for Servers, IoT, and Industrial Systems
