20/24-Pin ATX Power Breakout Board, Case Options

Bring compatible ATX power-supply rails to accessible terminals with a breakout board. Choose the bare-board option or the pictured package with an acrylic case.

• ✅ Access several supply rails - terminals expose the listed ATX outputs.
• ✅ See a voltage indication - the board includes a display.
• ✅ Choose the enclosure package - with-case and without-case selections differ.
• ✅ Connect supported USB loads - listed USB outputs add connection points.

Plan a Protected Bench-Power Arrangement

Check the PSU connector and pinout before connecting; not every 20/24-pin computer supply is standard ATX. Available current and minimum-load behaviour depend on the PSU, not the breakout board alone.

Provide suitable fusing, insulation and an enclosure. The DC barrel socket can have different roles, so follow the actual board diagram and do not connect conflicting sources. This is not a certified standalone bench supply.
