High-Quality PC Power Supplies | Reliable ATX/SFX PSUs for Gaming & Office PCs | 80 PLUS Certified

To pick the best power supply for your PC, there are some specific parameters you have to consider. You should begin by estimating the total wattage used by the major components of the PC, which are the CPU, graphics card, motherboard, hard disks, peripherals, and other items. There are specialized tools that can compute the total wattage. After getting the estimate, select a power supply unit that has at least 20% more wattage than what you calculated to leave room for future additions, and heavy usage. The form factor, such as the shape and design of the unit, should also be considered to ensure that it fits the PC case, together with the other components like the connectors and ports. Along with all that, consider the level of efficiency, protection features, and modularity that you require.
