eXtreme Power Supply Calculator Lite v2.5

ATTENTION: ONLY FOR PERSONAL, NON-COMMERCIAL USE ONLY

The recommended total Power Supply Wattage gives you a general idea on what to look for BUT it is NOT a crucial factor in power supply selection! Total Amperage Available on the +12V Rail(s) is the most important, followed by the +5V amperage and then the +3.3V amperage.

eXtreme Power Supply Calculator Pro version contains Amperage per +12V, +5V and +3.3V power supply rails, recommended UPS rating, multiple video cards and more. See the Features Comparison table here.

System Type: ¹

Attention: Dual or Quad Sockets means you have more than one
physical CPU (AMD 4x4 for example, or server board with 2 or more processors).
