Research: PSU [Day 24/25]

Power Supply Unit(PSU) is one of the most important hardware for the PC as it is what makes everything run. What the PSU does is converts AC into low-voltage regulated DC power for the components of the computer to utilize. Most PC's PSU are in the form of a square metal box with a large bundle of wires on one side, an airvent and a C13/14 inlet connector.  There is another type called Modular. The modular PSU provides a detachable cable system which reduces the clutter and removes the risk of interfering with other components as well as better air flow for the case. The life span of a PSU depends on the quality of it. The better the quality, the longer it last and it helps with a larger or higher speed fan because overheating is the major cause of PSU failure. The MTBF(Lifespan measurement for PSU) value of 100,000 hours(approximately 11 years) is common with most units.
