Power supply

Supplies power throughout the computer. Power supplies convert potentially lethal 110-115 or 220-230 volt alternating current (AC) into a steady low-voltage direct current (DC) usable by the computer. A power supply is rated by the number of watts it generates.
WARNING: Do not open the power supply, it contains capacitors which can hold Electricity (WHICH CAN KILL) even if the computer is power off for a week, if not longer. If you do open it, WHICH IS NOT RECOMMENDED, take all precautions and ensure you work with one arm behind your back to direct the electricity away from the heart. Also ensure that you have no jewelry on (such as a watch or rings). However, again, THIS IS NOT RECOMMENDED, and still cannot protect you 100% and is still potentially dangerous. Because of these precautions, no extensive information will be found on this page about opening power supplies.
