Manw 20/24 Pin ATX Benchtop Power Adapter with USB 5V Port (Blue)
Converts an ATX supply into a benchtop unit with 3.3V, 5V, 12V and -12V outputs, each protected by a replaceable 5A fuse
- Converts an ATX supply into a 4-channel benchtop source with 3.3V, 5V, 12V and -12V rails
- Each output channel protected by a replaceable 5A fuse with dedicated ground binding post
- On-board 24-pin ATX connector, power indicator and switch simplify bench control
- PCB plastic spacer design prevents short circuits during prototyping
- Supports both 20-pin and 24-pin ATX power supplies for flexible compatibility
Benchtop ATX Power Adapter
This Manw adapter converts a standard ATX power supply into a benchtop unit for embedded electronics development. It provides four voltage channels including 3.3V, 5V, 12V and -12V through binding posts for easy connection. Each channel includes a replaceable 5A fuse and a dedicated ground connection. The board features an on-board 24pin ATX port, power indicator and power switch for convenient control.
Compatibility Check
Verify that your ATX power supply uses a standard 20 or 24 pin main connector to match the on-board port. Ensure your project voltage requirements align with the fixed 3.3V, 5V, 12V and -12V outputs provided. Confirm the 5A per channel fuse rating is sufficient for your intended load current. The PCB includes plastic spacers to prevent short circuits during bench use.
Included Accessories
The package contains two identical adapter boards, allowing simultaneous use in separate projects or a redundant setup. Each board delivers the same four regulated voltage channels with independent fuse protection. The blue PCB colour aids visual identification on a crowded workbench. No additional cables or software are included with the adapters.

Questions about this item
What connectors and accessories come with the adapter, and does it include an ATX power supply?
The package contains two 20/24-pin ATX benchtop adapter boards in blue. Each board has a standard 24-pin ATX input, four voltage output channels with binding posts, replaceable 5 A fuses, a power switch and an indicator LED. An ATX power supply is not included and must be supplied separately.
The title mentions 20/24-pin — which ATX connector versions does the on-board port actually accept?
The on-board connector is a standard 24-pin ATX socket that mates with both 20-pin and 24-pin plugs from the power supply, so either version can be used without an extra adapter.
What do the 3.3 V, 5 V, 12 V and -12 V outputs mean for powering a typical embedded project?
The board breaks out four regulated rails — 3.3 V, 5 V, 12 V and -12 V — each protected by a replaceable 5 A fuse and provided with a binding-post ground, giving direct access to the voltages most microcontroller and sensor circuits require.
