Without a power supply, your computer is basically a pile of organized metal and plastic. Power supplies are no doubt the most important component because it is what gives life to the individual parts.
Power supplies like this one from AcBel, have the responsibility of converting Alternating Current (AC) to Direct Current (DC) which is what your computer requires. Power has to get to the motherboard, as well as other components of your computer. The original ATX main connector was a 20-pin connector.
As technology has progressed, more modern boards use a 24-pin connector. This computer power supply from provides a 20 + 4 pin connector making it compatible with both 20-pin and 24-pin connection types since both are still used.
Most computers use power supplies between 200W and 500 Watts. The AcBel API5PC17 Computer Power Supply provides a maximum output of 390 Watts. Power supplies also commonly get hot while converting all that energy into DC current. Provided in the power supply is an Intelligent-Thermal Fan to keep it cool and provides a high quality performance.
