A 450W power supply is enough for mid-range to high-end gaming systems. Despite its name, it is a bit shallow. It is only 6 19/64″ deep, and features a 140 mm fan on the bottom. It doesn’t have an active PFC circuit, but it does come with a voltage selection switch. It includes a main motherboard cable with a 20/24-pin connector, two ATX12V connectors, four SATA power connectors, a peripheral power cable with three standard peripheral power connectors, and a floppy disk drive power connector.
A power supply is an essential part of a PC. It supplies electricity to the components installed in a PC. It is your first line of defense against power problems externally, so a low-quality power supply can cause damage to your computer’s components. We recommend a 550W or higher power supply for the best performance. For best results, get a high-quality unit that is able to handle the added workload.
If you live in an area with high ambient temperatures, you’ll benefit from a higher-rated power supply. The higher the power supply, the more money you’ll save. In a hotter climate, a higher-rated power source will help your computer run more efficiently. A low-heat power supply also means less noise from your fan and less work for you to keep your PC cool.
