XHM229 ATX Power Supply Breakout Board Why this product helps you Quickly convert an ATX (and partial BTX) PC power supply into a reliable benchtop power source for testing, repairs, and prototyping. Provides the four regulated rails you need (12V, +12V, 5V, 3.3V) with individual 5A replaceable fuses so faults are isolated and easy to fix. Saves time and reduces risk when diagnosing motherboards, drives, or other components without installing the supply in a full system. Key features and benefits Four regulated outputs: 12V, +12V, 5V, and 3.3V delivered clearly and stably for componentlevel testing. Perrail protection: Each voltage output is protected by a 5A replaceable fuse to prevent damage and enable quick fuse replacement on the bench. 24pin motherboard connector: Directly powers motherboards and provides stable rails for standard PC diagnostics and component testing. Ground terminals and binding posts: Dedicated grounds and easyaccess binding posts simplify safe connections to external devices and test equipment. Power indicators and switch: LED indicators confirm which rails are active; an integrated module switch lets you turn outputs on or off without touching the supply. Durable construction: Built PCB with quality components and a robust 128 x 48 x 30 mm (5.04 x 1.89 x 1.18 in) frame for consistent performance in workshop or industrial use. Compatibility and performance Compatible with standard ATX power supplies and partial BTX variants that use the 24pin interface. Designed for benchtop and diagnostic use where stable multiple voltage rails and individual fuse protection are required. Compact footprint makes it easy to integrate into a workbench setup or a small station. Practical applications System diagnostics and : Power an ATX motherboard outside the case to isolate boot problems, test RAM and CPU, or update firmware. Component testing and data recovery: Run hard drives, optical drives, and other 12V/5V devices directly from the breakout board while monitoring power rails. Electronics bench work and prototyping: Supply multiple regulated voltages to DIY projects or lab experiments without building a dedicated multirail supply. What you get XHM229 breakout board with 24pin connector, binding posts, ground terminals, LED indicators, integrated switch, and four replaceable 5A fuses. Compact, durable PCB assembly sized 128 x 48 x 30 mm (5.04 x 1.89 x 1.18 in) for stable, longlasting use. Safe, clear, and reliable power for bench testing, repairs, and prototyping with ATX/partial BTX power supplies.
