Power supplies
Power supply units
Compare wattage, efficiency ratings, and modular cabling before you choose a PSU. Check your system's total power draw first, then match the unit's rating and connectors to your build.
Find the right wattage
Each unit is listed with its rated wattage, efficiency certification, and cable configuration so you can match it to your components and cabinet clearance.
Wattage
Calculate your system's total power draw, then add headroom for future upgrades and stable rail performance.
Efficiency
Review efficiency ratings and certification levels to understand how much power is lost as heat during conversion.
Cabling
Check modular cable configurations and physical dimensions to confirm clearance inside your cabinet or chassis.
