When buying a used power supply (PSU), you have no idea of the part's history, including its age, how it's been used, and how well it has been maintained.

Switching transistors from silicon carbide are to increase the efficiency of voltage converters; MSI is installing them in a 1.6-kilowatt power supply unit.

A true pW-power operation is enabled thanks to the adoption of an architecture leveraging transistor operation in super-cutoff, the elimination of voltage regulation, and current reference. Indeed, ...

For example, the LTM4655 is a 40 V IN, dual 4 A inverting μModule regulator, with two fully independent output channels, each configurable for positive or negative output, and is already EN550222 ...

A non-modular power supply has all of its interior cables hardwired into the side. Whether you need them or not, you'll get every single cable in a tight bundle attached to the side permanently.

Unregulated, privately built lines that power many oil and gas sites have been blamed for sparking two recent Panhandle fires. San Antonio Express-News Hearst Newspapers Logo.

Most power supplies weigh less today but a closer look at their ratings will tell you they are capable of handling more power. ... The clue was the control voltage that should have read closer to 28 ...

After we last saw [David Lovett] of [Usagi Electric], he was knee-deep in trying to fix a DEC PDP-11/03 power supply, which fortunately led to a fixed PSU and a very happy PDP-11/23 system installe… ...

Still, the power supply should never be an afterthought when you’re building a PC or buying a new one. There are a few important rules to follow when you’re picking out your PSU, ...
