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 ...

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 ...

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 ...

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 ...

Your PC needs clean power to perform at its best and remain stable. You don't skimp on your other components - don't skimp on the power supply. CPUs and GPUs may be the beating heart of a gaming PC, ...

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 ...

Hack #26 from PC Hacks by Jim Aspinwall (O’Reilly Media). Adjusting the power supply voltage to your CPU can make all the difference between an erratically performing speed-hack and a stable screaming ...

Power-supply designers frequently encounter projects where the input voltages are much higher compared to the low output voltages usually require to power the target equipment. Typical output needs ...

A power supply for electronic devices. Also called an "AC adapter" or "charger," power adapters plug into a wall outlet and convert AC to a single DC voltage. Computers use multiple DC voltages, and ...

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.
