  • Converts ATX 24-pin supply to bench binding posts
  • Delivers +3.3V, +5V, +12V, -12V for lab circuits
  • Independent replaceable fuse per channel protects against shorts
  • Onboard power switch and LED show status instantly
  • No soldering required — secure wires to posts for stable output

ATX breakout board for bench power

The SMUGDESK XHM229 converts a standard desktop ATX power supply into a multivoltage bench source for electronic debugging and DIY hardware projects. It connects via the 24-pin ATX mainboard connector and exposes four DC rails through color-coded binding posts. No soldering is required, allowing quick wiring for lab testing and small-device power.

Per-channel replaceable glass fuses

Each output channel — +3.3V, +5V, +12V and -12V — is protected by an independent, replaceable glass fuse that guards against short circuits and overcurrent. An onboard physical power switch cuts output without unplugging the PSU, and an LED indicator shows working status at a glance.

Suits hobbyists and technicians needing quick

Builders who require adjustable voltage regulation, higher current than the module can pass, or isolated outputs should look at a dedicated programmable bench supply instead.

Questions about this item

What can I actually power with the +12 V and +5 V outputs once the adapter is plugged into my ATX supply?

You get direct access to the ATX supply's +12 V, +5 V, +3.3 V and -12 V rails through binding posts, so any bench load within the PSU's rated wattage on those rails can be driven.

Does the 24-pin ATX connector limit the current I can draw from each voltage rail?

The 24-pin ATX input passes whatever current your power supply can deliver on each rail; the board adds per-channel glass fuses for protection but does not impose its own current ceiling.

How much space does the board need inside a chassis or on a bench, and how is it mounted?

The bare FR4 PCB has no mounting holes; it sits on a work surface or shelf and connects via the 24-pin plug and binding posts, so allow room for cables and wire leads.
