ModMyMods ATX Power Supply Breakout Board (MOD-0303)

Use your computer power supply for other electronics projects. This breakout board for ATX power supplies takes the 24-pin main cable in its 2x12 socket and brings the +12V, +5V, +3.3V and -12V rails out to binding posts, each output protected by a fast-blow 5A/250V fuse. A slide switch turns the power supply on and off, and an LED shows when it is running.

Pieces in the pack

1

A bench power supply from a PC power supply

Plug the 24-pin cable of an ATX power supply into the socket and switch the board on: the power supply starts and its rails are available on the binding posts, ready for test leads, banana plugs or bare wire. It is a simple way to power 12V and 5V projects on the bench.

Fused outputs

Each output pair has its own fast-blow 5A/250V glass fuse in a clip holder, which cuts that output if a short or overload draws too much current.

Switch and indicator

The slide switch on the board replaces the power button of a PC and starts or stops the power supply. The red LED lights up when the board has power.

20-pin power supplies

If your power supply has a 20-pin main connector, insert it at the end of the socket marked with a dot and leave the four positions at the other end empty.

Technical data

Notes

• Switch the power supply off at its rear switch before you plug in or remove the 24-pin connector.
• Do not draw more current from an output than its 5A fuse allows; replace a blown fuse only with the same type.
