Useful for electronics hobbyists, this linear workbench desktop power supply circuit converts a high input voltage (12V) from the SMPS of a PC into low output voltage (1.25 to 9 volts). An adjustable ...

We’ve often heard you should do everything twice. The first time is to learn what you need to do, and the second time is to do it right. We bet [Ian Carey] would agree after taking his old linear ...

The circuit of power supply for PC works with a mains voltage of 230VAC to produce an output of 13.8V at 5A due to rectification. This project came upon the modification of a PC switch mode power ...

The power supply unit (PSU) is one of the PC components that we tend to take for granted. It sits in the case with a bunch of wires sticking out of it, and maybe once in a while we blow some air blown ...

Antec is arguably the most well-known name in the computer power supply industry and rightfully so. They've been around since 1986 and have provided quality power supplies, cases, cooling products and ...

Economy of scale is a wonderful thing, take the switch-mode power supply as an example. Before the rise of the PC, a decent multi-voltage, high current power supply would be pretty expensive. But PCs ...

Power supplies are a frequently misunderstood—and overlooked—PC component. Many users choose a PC power supply based on total wattage alone, assuming that higher is always synonymous with better.

A system that converts AC current from the wall outlet into the DC currents required by electronic circuits. A computer power supply converts AC into multiple DC voltages. For example, 12 volts is ...
