The eXtreme Power Supply Calculator contains 1300+ CPUs including latest processors from Intel and AMD, latest graphics cards from NVIDIA, AMD and more!
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.
System Type: Based on physical processor(s) or # of sockets. Multicore CPU counts as a single processor. For example: for a single Core 2 Duo you should select 'Single Socket' as System Type.
Electrolytic capacitor aging. When used heavily or over an extended period of time (1+ years) a power supply will slowly lose some of its initial wattage capacity. We recommend you add 10-20% if you plan to keep your PSU for more than 1 year, or 20-30% for 24/7 usage and 1+ years.
Recommended UPS rating is based on the selected components only and does not include monitor, printer or any other electronic devices that are not a part of the eXtreme Power Supply Calculator.
