Atx Bench Power Supply Wiring Diagram Circuit Diagram Step 1: the plan. an atx power supply can deliver different voltages with high currents. the plan is to modify the power supply to make it easier to use it for your electronic projects. the different colour wires coming out of the power supply have different functions: black = ground. orange = 3.3 vdc. red = 5 vdc. yellow = 12 vdc. Hello friends!in this episode i will show you how i converted an old atx psu into a bench power supply with fixed and variable outputs. some of you asked me.
How To Build A Bench Power Supply From Atx Part I Do what [maker y] did— grab an atx supply and get building! atx power supplies work as a great basis for a bench power supply. they have 12 volt, 3.3 volt, and 5 volt rails, and they can supply. I needed a bench power supply for testing, fixing, and building my electronics and iot projects. despite the fact that i could buy one, i decided to recycle an atx power source i had stored, and create a new bench power source from it. for that, i started defining my requirements. i would need: one 3.3v output; two 5v output ; one 12v output. Step 1: background. first, a bit of background on a typical atx power supply: computer power supplies are switch mode power supplies (smps), which use high frequency switching circuit elements to provide a high quality output voltage, with good energy efficiency. one side effect of this technology is the minimum load requirement that each power. Step 1: 3d printing the frame. before diving into the circuit assembly, start 3d printing the frame to house and support the psu and other components. while you work on the electronics, your 3d printer can be creating the necessary parts for your lab bench power supply. download the 3d printable files from my printables page.

A computer atx power supply can be easily converted into a versatile and powerful power supply for your workbench. in this video, i’ll show you how easy it. There are a number of ways to convert a standard computer atx power supply unit into a usable bench top power supply. you can keep the 20 pin molex connector attached and connect directly into it or cut it off completely and group together the individual wires keeping the same colours together, reds to reds, blacks to blacks etc.
