Computer power supplies convert the alternating current (AC) electricity from your wall outlet into direct current (DC), which is the kind of power your PC uses. They power all the other PC components with dedicated connectors that limit the need for additional outlets. ATX power supplies have a 20-pin connector, while the ATX12V versions have a 24-pin power connector to fit compatible motherboards. ATX12V motherboards have dual 12V rails that split amperage for added safety. Smaller power supplies take up little space in small laptop cases. Many power supply unit (PSU) models have an 80 PLUS® certification to ensure optimal energy efficiency.

The Right PSU Improves Your Computer's Performance

Whens putting together server power supplies, consider the needs of the PCs connected to the system. The computer wattage should be equal or greater than the amount of power required by all the components of your PC, and you can use simple online tools to calculate this value. You only need to input the model of your CPU, GPU, motherboard and other computer accessories, and these tools automatically calculate the minimum wattage you need. Using a computer power supply with a slightly higher wattage than needed provides protection for your components. The PSU runs at less than its maximum capacity, which could prevent overheating inside the computer case. Higher wattage computer power supplies let you upgrade your CPU or GPU in the future without worrying about power consumption. A PSU only consumes the amount of electricity your computer components use, so you won't have to worry about electric bills, even if you choose a model with a higher wattage. If you have a limited budget, choose a refurbished power supply that provides the same performance of a brand-new one at a lower price point.

80 PLUS Power Supplies Provide Optimal Energy Efficiency 

Many power supplies have an 80 PLUS certification that classifies their energy efficiency. PSUs with the standard 80 PLUS certification offer 80% efficiency at 20%, 50% and 100% loads. There are also Bronze, Silver, Gold, Platinum and Titanium 80 PLUS power supplies with higher energy efficiency than the standard 80 PLUS options. This helps maximize efficiency even in high-load situations.

ATX Power Supplies Connect Storage Drives

ATX computer power supplies feature a 20-pin main power connector and SATA connectors for storage drives that require an outside power source. ATX12V PSUs have a 24-pin main connector, and do not require the auxiliary power connector. This PSU standard supports dual 12V rails to power modern computer components safely and effectively. EPS12V power supplies use an 8-pin power connector for plugging directly into the processor. Many servers or high-end desktop computers use these power supplies for efficient energy options. There are also smaller power supplies that fit easily into laptop cases.

Modular Power Supplies Offer Flexibility

Many PSUs feature hardwired cables to power all the CPU accessories. Modular computer power supplies offer flexibility, as they let you add or remove cables as needed. Removing unneeded cables allows optimal airflow inside the computer case for protection against overheating.
