ATX Power Supply Module

This ATX power supply module provides a 24-pin connector compatible with 20, 20+4 and 24-pin headers. It is built for bench testing and arcade panel builds where a standard PSU must be broken out to screw terminals. The compact 52 by 87mm board weighs approximately 50g and fits tight spaces. It is not suited for builders who need a fully enclosed power supply unit with integrated cables.

Lock Switch and Status Indicator

A lock button switch allows direct power on and off control without a motherboard header. An onboard indicator shows the module status at a glance. Two external button connectors let you mount a remote switch when the adapter sits inside an arcade panel. No software or drivers are required; the hardware controls are entirely self-contained.

Screw Terminal Breakout

High-quality screw terminals rated at 16A per position distribute six +5V, ten ground, one -5V, one -12V, four +12V and three +3.3V connections. The -5V rail only functions if the host PSU supplies it. Terminals accept stripped wire for custom looms, removing the need for pre-crimped harnesses. The open board design demands careful insulation in metal enclosures.

Questions about this item

Will the screw-terminal block need periodic re-tightening or replacement after extended use?

The terminal block is rated at 24A per position with 16A connectors; no scheduled re-tightening or replacement interval is specified.

Under continuous load, which rail reaches its 16A limit first?

The +5V rail has six 16A connectors, the +12V rail four, the +3.3V rail three, and the -12V and -5V rails one each; the rail with fewest connectors will saturate first.

Does the module generate noticeable heat or noise when powering a system all day?

The board has no fan; heat depends on total current drawn through the 16A connectors, and the on-board indicator shows power status without audible noise.
