Bench Power Supply Atx

Atx power supplies are fixed but for almost all purposes they re very accurate they have a good selection of voltages 12 5 3 3 5 12 and they re extremely powerful the one i m using can supply 6a on the 12 rail and this is a pretty crappy old power supply.

Bench power supply atx. This instructable will show you how to make a professional looking bench power supply. Lab bench power supplies are very cost prohibitive but luckily power supplies for desktop computers can easily provide 30a for under 20. The standard computer power supply unit psu turns the incoming 110v or 220vac alternating current into various dc direct current output voltages suitable for powering the computer s internal components and with a little bit of imagination it is possible to convert atx psu to a bench power supply.

Atx workbench power supply project. A power supply that is fuse linked. Aside from the atx power supply itself we will need a few additional components to build our bench supply.
