The lower overall system-level power draw is a result of the breakthrough system design developed by Dell EMC. The system aims to
maximize performance-per-watt through a combination of energy efficient technologies, optimized thermal designs and intelligent fan
control algorithms. System fan control algorithms use an extensive array of sensors that automatically monitor power and thermal activity
to minimize fan speeds based on system cooling requirements, reducing the power required for cooling.

Description
Dell EMC PSU portfolio includes intelligent features such as
dynamically optimizing efficiency while maintaining availability and
redundancy. For more information, see, the Power supply units
section.
The Dell Enterprise Infrastructure Planning Tool (EIPT) is a tool that
helps you plan and tune your computer and infrastructure
equipment for maximum efficiency by calculating hardware power
consumption, power infrastructure and storage. Learn more at
Dell.com/calc.
PSU power monitoring improvements include:
•
Power monitoring accuracy of 1%, whereas the industry
standard is 5%
•
More accurate reporting of power
•
Better performance under a power cap
Use Dell EMC systems management to set the power cap limit for
your systems to limit the output of a PSU and reduce system power
consumption. Dell EMC is the first hardware vendor to leverage
Intel Node Manager for circuit-breaker fast capping.
