PFE1100-12-054NA White Paper Issue 6
Conclusions
This paper demonstrates the bene?ts of implementing the PFE1100-12-054NA in the server environment.
Table 16 shows the data for Climate Savers Silver, Gold and Platinum. It demonstrates the PFE1100-12-
054NA’s
achievement in exceeding the Platinum speci?cation. The ef?ciency data in Table 16 is the actual data re-
corded by EPRI when this power supply was submitted for 80 Plus, Energy Star and CSCI compliance.
The design is optimized where the load really counts, between 10% and 50% of the load. As the majority of
servers operate in this area this is the most sensible load range to optimize a power supply. Having said that,
the difference in ef?ciency across the entire load range from 20% to 100% load is within 1.12%, and from 10%
load to 100% is just over 4%.

The bene?ts of the 54mm dimension have been shown to increase system I/O capabilities , (the limit in that
form factor, has up to now, been down to the maximum power density that could be achieved), as the
motherboard width can increase to 12 inches.
54mm wide designs have been in the marketplace at power ranges from 500W to 850W, but that remained
the limit, as the primary drive in designing for higher power was the ef?ciency. Server power supplies as
narrow as 54mm require optimum ef?ciency as the air?ow will never be optimum. Typically the PSU fan has
to draw air from the output connector toward the AC inlet connector, with heat sinks, electrolytics, and
magnetics restricting that air?ow throughout the enclosure.
OEM’s embracing this design, can, in turn develop energy ef?cient hardware, and with expected models
being available in 600W, 850W and 1100W outputs, with identical connectors and pinouts, the ability to scale
up and down in power levels while retaining form ?t and function is invaluable.
The implementation of this power supply is a good solution for the entire supply chain, from the
manufacturers, to the OEM’s and in turn the end users. The ef?ciency of the unit enables utility and C02 re-
ductions to be realized, the mechanical dimensions allow for more ?exibility with the motherboard design,
and the data center managers can realize improvements towards system performance and feature sets while
achieving invaluable PUE reductions.
