The new ENERGY STAR 4.0® guideline effective on July 20,
2007 has as one of its primary requirements an 80% efficient power
supply. In anticipation of this new requirement, HP has led the
industry in bringing the 80% efficient power supply to customers
months in advance as a great solution towards energy efficiency. HP
business desktops can be upgraded with an 80% efficient power supply
option.
What are the benefits of an 80% efficient power
supply?
The 80% efficient power supply offers a range of
potential rewards which benefit you financially while helping
the environment by reducing power consumption:
•
Increased power supply reliability
due to greater efficiency
•
Decreased system maintenance due to
increased reliability
•
Lower TCO due to reduced maintenance
and longer equipment life
•
Improved worker environment with less
noise from the PC
•
Potential reduction in cooling bill
due to less heat being generated by PCs
How is an 80% efficient power supply different
from a traditional power supply?
An 80% efficient power supply is at least 80%
efficient at 20%, 50%, and 100% loads whereas current power
supplies range from 65-75% efficiency.
80% efficient power supplies are designed
with active power factor correction (PFC). Active power
factor correction uses an active circuit to help current and
voltage correlate with each other. When this happens, apparent
power and real power approach each other. Apparent power is
the current drawn by a system, whereas real power is the
current actually available for use by the system. If they are
equal, then the power factor is 1.
A .9 PFC means that 90% of apparent power is
actually transferred to available real power. Power supplies
that aren't power factor corrected tend to cause unpleasant
variations in AC voltage that can affect or even damage other
equipment on the same circuit.
What makes an 80 Plus power supply
HP's 80% efficient power supplies carry the 80
Plus logo. This logo means that they were 3rd party tested
through the 80 Plus program to meet the 80% efficient
standard. For more information on the 80 Plus program, visit http://www.80plus.org/ website.
HP is the first PC manufacturer to sponsor the
80 Plus program. The 80 Plus program is a joint endeavor by
electric utilities, computer manufacturers and consumers
designed to promote the use of 80% energy efficient power
supplies to ensure a standard of energy efficiency in power
supplies.
In fact, the 80 Plus Program has been
instrumental in working with the Environmental Protection
Agency (EPA) to make 80% efficient power supplies part of the
new ENERGY STAR 4.0 specification, which goes into effect on
July 20, 2007.
HP Business Desktop PCs - 80 Plus, available
today
The 80 Plus power supply is available today as
an option on select models of the 5,000 and 7000 Series
Business Desktop PCs What is great about this solution is that
it can be configured into any combination of modules to
deliver improved energy efficiency over our standard power
supply.
Take advantage of incentives from public
utility companies
Another benefit of buying HP business desktop
PCs with an 80 Plus power supplies is that your organization
can potentially collect incentives from the public utility
companies involved in the 80 Plus initiative. Please check
with your public utility to see if they are a sponsor of the
80 Plus program or if they have other energy efficient
incentive programs.
Don't wait to start taking advantage of the many
benefits of desktops with 80 Plus power supplies - get started
today in helping your bottom line while helping the
environment at the same time.
