Computer PSU's provide constant electricity to the computer allowing it to work properly and these units are considered crucial if you own a computer. There are many facts about PSU's that not many people know about and this article is going to elaborate on some facts about computer power supply units.
The life span of the device is measured in mean time between failures. Higher mean time between failures is always preferred since they ensure a long life span. Power supplies often last lesser then what the manufactures suggest. While an ordinary computer PSU has a life span of 100,000 operating house, some PSU's have a life span of 200,000 operating house. These numbers are rough estimates of the life of these units and due to various factors the life span of a power supply unit can be reduced by 50%.
A computer power supply that has sleeved cable looks aesthetically pleasing. Sleeved cables are easier to clean and maintain hence they are preferred by many people. These sleeved cables also prevent detrimental effects on air flow hence they are often recommended over normal cables.
A greater power capacity that is greater output wattage is not always good and ideally a computer power supply unit should have a wattage that is not too low or too high. Extremely high output is usually of no use and extremely low wattage units do not function optimally. Greater output wattage does not ensure that the extra electricity is used for high end graphic cards.
A good computer PSU should supply adequate electricity to all the parts of the computer and not to just one specific part. A good power supply unit should have added features like short circuit protection, under voltage protection, over voltage protection, over temperature protection and over current protection.
