Why you need this module Supplies the four common ATX voltages (+12V, 5V, 3.3V, 12V) from a standard 24pin PSU so you can quickly power and test desktop components or bench electronics without rewiring or soldering. Builtin safety and clear connections reduce risk and save time when diagnosing power issues or running repeated tests. Key benefits Versatile power delivery: One compact module provides all four voltage rails used in PCs and many electronics projects, simplifying bench setups. Safer testing: Each rail uses a 5A replaceable fuse for overcurrent protection and an integrated power switch lets you disable all outputs instantly during work. Clear, reliable connections: Binding posts for every voltage output and ground give straightforward hookup and support the PSU's maximum current capacity. Visible power indicators show which rails are active, avoiding guesswork. Compact and compatible: Small 128x48x30 mm footprint with a 24pin ATX compatible interface that works with most desktop chassis power supplies for consistent, repeatable performance. What makes it stand out Combines full ATX rail access, replaceable fusing per rail, a master switch, and labeled binding posts in a single breakout module designed specifically for testing and troubleshooting. Durable, compact design suited to repeated bench use without occupying much space. Typical applications PC and diagnostics: Quickly isolate and power test motherboards, drives, fans, and other PC components during troubleshooting. Electronics prototyping and lab work: Power microcontroller boards, sensors, and peripherals with the specific ATX rails they require. Power supply verification and maintenance: Confirm PSU rail voltages and behavior under load safely, or swap PSU units without reconfiguring wiring.
