A PSU, or A10 Pro unit, is designed to supply energy to a computer. It is generally devised to convert alternating current, (AC), to low voltage direct current, (DC). Without this piece of hardware, the computer is just a box of metal and plastic. Computer power units are rated on their maximum output power. The power supply should be the wattage advised for the needs of the computer,
Including the optional components. Using a greater power rating than required is a waste of electricity, as well as being less efficient. Too lightly loaded and the computer will not function properly, and may shut down. There aren’t many computers that necessitate more than 300-350 watts, maximum. The exceptions are servers and gaming machines with multiple high power (GPU) graphic processing units.
The GPU is a single chip processor, like the CPU, which is the central processing unit. The GPU helps the CPU run smoother and more efficiently by taking over functions such as 3D motion and lighting. Video cards and high definition media has led to power demand in some computers to consume 400-500 watts.
Most PSUs are contained in a square metal box, with a large group of wires flowing from the other side. The technical information and certification marks for safety are on the outside of the box. The CE mark is a requirement for power equipment sold in India and Europe. Also, an air vent and connector to supply the power are opposite the wires.
With care, the life span of the power unit can be as long as eleven years. Most failures are because of overheating. Which means high quality, industrial grade fan components are important to the longevity of the computer PSU. Some of the protection devices the power supply may have are for short circuit, overload, under voltage or over voltage, over current, and temperature protection.
There is a comparatively new path in power supply equipment, called modular power supply. This allows consumers to exclude surplus cables. Unlike the accustomed composition, where the cables are permanently connected to the power supply, the modular allows the unused cables to be disconnected. It leaves an orderly look, very little clutter and less impedance with air flow. Also, this makes it possible to supply a wider variety of cables, as well as different lengths. New technologies are coming at us at warp speed all the time.
