I will talk about why many friends like to DIY using old power supplies from computers. Use them as a power supply for the load, such as connecting to car power amplifiers or mini amps. The main thing is that the Powersupply can convert AC or house electricity to DC power at the Output. It also provides multiple sets of output voltages, such as 3.3V, 5V, 12V, which is the 12V voltage. It is the voltage that most devices tend to use and it meets the load needs just right. Most importantly, its 12V output voltage usually provides more than 10A of current. This one provides the maximum current of 18A. This is one of the reasons why it is so popular. Which wire is 12V? Normally, the +12 wire is the yellow wire, the ground wire is the black wire, and the green wire is the switch-on wire. If you jump to the ground, it will turn on the device. If you want the current to flow easily, I usually pull all the yellow wires together, such as this one that I left, I cut it, leaving only the yellow and black wires, and then jump to the ground wire. I connect it like this to switch it on. I think switching power supplies are much better than transformers. For example, large, heavy transformers like this, when we adjust it to DC current, the current is not even half of this switching power supply. If you don't like the wires that are too many and cluttered, you can solder them and disassemble them. I will change the wires to real copper wires for cars that have small wires inside to use instead. Here, if I solder it out, it will be a hole, a hole like this. I will divide the copper wire into 2 bunches, dip it in solder, and insert it into the 12V positive terminal. After that, solder it, put the solder, and make it stick together tightly. After that, cut it short. The ground terminal is done the same way. We will get two thick wires. Use it like this. And then assemble it, tighten the nuts back like before. Put the iron frame in, put the nuts in. We will get beautiful wires that come straight from the Power Supply. Let me check and see how strong the current is. I will use the positive terminal and the ground terminal to short-circuit this spring. Here, the spring wire is hot and the light is bright red. Let me check and see how much current is flowing. Here, 11.06 A at once. And another thing that I like is that we have an automatic power cut-off system. In case the two terminals touch each other, it will help save us from the dangers of short circuits and save our circuits as well. Notice that the fan will stop spinning and the light will go out immediately. It can be considered that it has excellent efficiency. I removed it from an old computer that I have. If my friends want a higher amp, such as 20A, 30A, second-hand ones, I have seen some for sale on Shopee and Lazada. I will put the link under this clip. For this clip, I will explain only this much for now.
