The power supply unit inside of an ASUS computer is responsible for providing power to all of the components inside of the PC. Some of these components are integrated into the motherboard – including ...

If you want to easily control the power in a circuit, you’ll probably reach for the classic toggle switch. While there’s certainly nothing wrong with that, physical toggles are a bit dated at this ...

I'd guess you are looking at a cap failure in the original PSU. 386 era is what, early 90s. 30+ years is a good run. If a replacement PSU doesn't have a switch, you could always hook it to a surge ...

A load switch is an electronic switch. It works like a relay to power supply rails in systems, but it has no moving parts. Load switches are increasingly found in today’s portable electronic devices, ...

A previous Design Idea outlined a relatively simple circuit in which a momentary pushbutton could be made to function like a latching, mechanical switch. The article generated a good deal of reader ...

Learn more about integrating GaN power FETs into switch-mode power supplies and what you must change when upgrading from silicon MOSFETs. The power-handling properties of GaN. The unique challenges of ...
