Diy Convert Old Atx Pc Power Supply To Bench Power Supply Youtube Construction. unscrew and remove the top half of the power supply case. you may need to pull a plug out of the main circuitry to fully separate the covers. these are nasty capacitors which hold huge amounts of electricity: strip the plugs and pull the wires through the hole in the case. A computer atx power supply can cost around $30, and can be salvaged from an old computer. save money by converting a cheap atx power supply that can be found in any discarded computer. this diy project will give you a power supply that produces a 3.3v, 5v, and 12v current, as well as some practice assembling basic electronics.
Diy Lab Bench Power Supply From Atx Psu Youtube 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. 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. 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 4: wiring the psu for bench power supply use. with the unnecessary wires and connectors removed, it’s time to wire the power supply unit (psu) for bench power supply use. this step involves connecting the essential wires and configuring the outputs for your desired voltage ranges.
