Making of a modding power supply. I’ve dreamt for quite some time now to get a decent laboratory power source. Now that I’ve made a few of these mods, my needs have been mainly two voltages: +5 and +12 volts. Once you get these out of the power supply, you’re going strong. Just add the most frequently used connectors that are used in PCs and the constructing and testing of new mods is eased quite a bit. One of the greatest benefits is that you don’t have to use your PC’s for testing, but you can test them with this device. This way, the poorly made connections etc. don’t danger the health of your beloved computer. So, let’s see what kind of a gadget I threw together.
