Modern power supplies for a personal computer are high-power devices. Old ATX-type units remain unclaimed, despite the fact that their resource has not yet been exhausted. If you have such a device idle, then you can build a laboratory power supply from it. In this case, special attention should be paid to the current limiting device, as well as the possibility of regulating its threshold. Most often, such a component is a TL494 type chip, since this is the simplest solution for remodeling.
