## Overview

This dual-pack ATX Power Supply Breakout Adapter Module offers quick, safe access to standard voltages (3.3V, 5V, 12V, -12V) via a 24-pin ATX interface. Designed for embedded system developers and DIYers, it features replaceable 5A fuses on each output, a compact footprint, and integrated power switch with LED indicator, making it an essential benchtop tool for efficient and protected power delivery.

## Description

Specifications: Product name: ATX power supply board Model: XH - M229 Compatible with the port: ATX (compatible with partial BTX type) The PIN number: 24 pin Switch: Yes Number of sets of output: Four sets of different voltage Size: 12.8x4.8cm/5.04x1.89" Quantity: 2 Pcs Package Included: 2 x Power Supply Test Module

Review: Works like expected - My only concern is they added the -12v as well as the 12,5,3.3v rails. -12v is for very low current(0.6A on a 350w) but they put a 10A fuse on it.
Review: Wish I would have ordered these a long time ago. - They work with 20 or 24 pin ATX plugs. My old home made breakout just not as neat. And I never fused my outputs so that's definitely a plus for these boards. I put stand offs on top of a ATX case and mounted one of them directly to the case. I will be a little fancier on using the other one. They work. There's definitely a small room for improvement as they would be far better if the board was thicker, stiffer, however that's me as I'm rough on my bench areas and things tend to bump and fall on things. Restricted room for working on projects. And these will be used when I don't need precision voltage from a larger dedicated bench supply placed out harms way. I mounted the one on a small 200 watt micro ATX, Babey ATX or whatever a person calls it. It fits in my palm. The board is basically the same size as the supply case. 10 amps at 11.98 volts, plenty for what it'll be used for.

### ⭐⭐⭐⭐ It works
*by G***S on November 20, 2022*

It works extremely well as a glorified power switch for a PC power supply. Don't try to attach high drain devices directly to it. The binding posts are weak and the traces on the board are thin.
