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 ...

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 ...

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 ...

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 ...

Which side of a PC case power or reset switch is positive or negative? (and can I damage my motherboard by connecting it incorrectly?) No, you won't damage a motherboard by connecting the power and ...

The venerable Stephen Woodward recently published the design idea (DI) “Flip ON flop OFF” that converts a momentary push button to a classic push-on, push-off switch. Figure 1 is an attempt to go ...

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 ...
