Best PC Power Supplies Compared in 2026

These five power supplies are compared on wattage, efficiency certification where explicitly stated, connector type, form factor and price. Wattages range from 500W to 1300W, and only some listings state an explicit 80+ efficiency rating, so this should not be assumed for every unit. Connector types and form factors also vary, from standard ATX to FLEX ATX, so buyers should check compatibility with their own case and components before choosing.
