The Power Supply Unit (PSU) is the only thing that stands between your precious CPU and 220/110 volts of jolting electric power. In some ways, it’s like a farm mill, converting alternating current (AC) to a more PC-consumable juice called direct current (DC); the same juice that flows to your motherboard, video card, hard drive and PC monitor. A good PSU can actually prolong your PC’s lifespan and will prevent your CPU from not sounding like an airplane engine from hell.
