ATX12V and ATX12VO PSU
Design Guide Addendum
Channel PSU Guidance
Intel’s Channel partners may have less control over motherboard and power supply design and need to follow industry standards to build their systems. Based on that premise, this chapter includes guidance using the most recent Intel CPUs and provides a table for a Power Supply characteristics to support socket compatible designs.
The table’s included in this document are used as the foundation for power supply compliance with PSUs listed on the Intel Power Supply Selector website: https://www.intel.com/content/www/us/en/collections/topics/power-supply-selector.html and https://compatibleproducts.intel.com/FeaturedLinks/psu.
Picking a power supply for any system requires planning and consideration for components used in the system. All of the information in this document provides a current that power supplies need to provide to the 12V rail for the CPU Power connectors. This information is necessary when choosing an appropriate power supply.
The following sections provide guidance for general power budgeting using the information included in this document for either a Desktop or HE-DT/Workstation based system.
Power supplies come in two standard ways to define the current provided by 12V power rails.
