Label Ratings Explained
The "Rating" is the label rating of the product. It is the absolute worst case power
consumption for a
fully configured system or chassis. This means all DIMM slots, CPU sockets, PCI slots,
HDD slots etc., are fully populated and are running at maximum capacity assuming the
worst case power load across the entire system/chassis. It is calculated on assuming
the highest power consuming hardware is installed, for example: 130W CPUs, quad
rank DIMMs, 15k HDD spindles etc. It also assumes highest fan speeds.
For these reasons, if you are running a system with 95W CPUs for example, it is not
realistic to provide the rating number as an accurate guide for your systems power
load. Use the Lenovo Power Configurator tool to better define your hardware's
power draw. The tool is available for download from:
