we show you how to kickstart and reuse a ATX PC computer Power Supply Unit (PSU) WITHOUT a computer. Old PC computer power supplies Make great power supplies for projects! They come with good overload and overheat protection built-in, and commonly offer out of the box 3 output voltages: 3.3 volts, 5 volts and 12 volts. But, getting them to work outside of a computer can be however a little tricky since when taken out of a PC, they may not even start at all! So, if you have never seen it, let me show you why and how to fix it / make it work.
Several IDE and floppy drives connectors, a 20-pin P1 molex, a 4-pin P4 molex to support Pentium 4 power and a 6-Pin P2 connector, no doubt we are dealing here with an ATX power supply version ATX12V1.0.
I'm using three 12-volts halogen light bulbs to test if we get power on the 3.3 volts, 5 volts and 12 volts rails.
Different power supplies may have other requirements for a stable voltage supply: minimal load required on 3.3V, 5v or 12V rail, "" voltage sense function, ... so, check out the documentation of your ATX power supply.
