XHM229 ATX Desktop Chassis Power Breakout Module Key benefits and why you need it Simplifies bench power for PC troubleshooting and DIY builds: connects a standard ATX or partial BTX power supply to clearly labeled outputs so you can quickly power and test components without a full chassis. Safer, controlled testing: each rail has a replaceable fuse and supports up to 5 A, reducing risk from overcurrent events; an onboard power switch and LED indicators let you confirm active voltages at a glance. Compact and easy to integrate: a small breakout board that fits on workbenches or inside test enclosures so you can add stable power distribution without taking up much space. What it does and how it stands out 24pin power simulation: the XHM229 includes a 24pin connector that simulates motherboard power input, enabling correct sequencing and stable operation of ATX/partial BTX power supplies during bench tests. Four regulated rails: delivers 12 V, +12 V, +5 V, and +3.3 V via clearly labeled binding posts for convenient access to common supply voltages. Replaceable fuses and 5 A perrail capability: each output is protected and rated up to 5 A, making the module suitable for most componentlevel tests and lowpower peripherals. Visual status and control: an onboard switch controls output and LEDs indicate which voltage rails are active so you can operate and diagnose quickly. Technical and physical details Model: XHM229 Outputs: 12 V, +12 V, +5 V, +3.3 V Current: up to 5 A per output (with replaceable fuses) Connector: 24pin ATXstyle connector for PSU connection Controls/Indicators: onboard power switch and LED indicators Form factor: compact breakout PCB, 128 x 48 x 30 mm (5.04 x 1.89 x 1.18 in) Mounting: general mounting compatibility for most workbenches and enclosures Connections: clearly labeled binding posts for each rail Typical use scenarios Bench testing an ATX power supply: connect the PSU to the XHM229 to verify rail voltages and stability before installing into a system. diagnostics and component testing: power and test motherboards, drives, fans, and other peripherals individually without a full chassis. DIY PC builds and prototyping: provide convenient access to standard PC voltages during assembly, troubleshooting, or when evaluating parts on a test bench. The XHM229 provides a compact, practical, and safe way to access ATX/partial BTX power rails for , testing, and DIY projects while keeping control and visibility over outputs.
