PC power supplies convert AC power into the correct voltage regulated DC power found in the internal components of a computer.
Modern computers use a universal switch-mode power supply. Some may have a manual switch to select your input voltage while newer models have automatic switches that adapt to the right voltage of the main component.
As computer parts and components become more energy-efficient, the need for a higher wattage PC is decreasing. As such, modern PC power supplies are also more efficient.
Whether you’re building a new desktop computer or you need a replacement, picking the right PC power supply will give you the best possible performance and reliability.
Energy-efficient PC Power Supplies
Efficiency is important to look at when buying a PC power supply, as it will affect how much you spend running your computer. A PC power supply with a higher energy efficiency rating will also help your PC to run cooler.
PC power supplies are rated using the “80 Plus” certification. This is the global standard adopted by most manufacturers. In general, the higher the rating – the higher the energy efficiency.
When you’re shopping for a PC power supply at Shopping Express, you can buy a true rated energy supply. The order of energy efficiency preference is:
