You may not give much thought to the power supply in your computer, but the quality of its power conversion output is an important consideration when it comes to energy efficiency. ENERGY STAR® guidelines are instrumental in driving requirements for energy efficiency. The ENERGY STAR® 4.0 specification requires a minimum power supply efficiency rating of 80%, which means you need to give your power supply a second look. HP currently offers outstanding flexibility on the 5000 and 7000 series Business Desktops – you can upgrade any configuration to an energy efficient power supply with ratings ranging from 80% up to 87% efficiency.
What are the benefits of an energy efficient power supply?
An HP energy efficient power supply offers a range of potential rewards which benefit you financially while helping the environment by reducing your overall 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 energy efficient power supply different from a standard power supply?
HP standard PC power supplies are rated between 65% - 75% in terms of their energy efficiency. This means that between 25% and 35% of the electrical energy which goes into the power supply is lost in the power conversion process. You still pay for this lost energy, but it never finds its way to your PC components. HP energy efficient power supplies are designed specifically to be more efficient at converting the power needed by your PC into usable energy.**
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 have variations in AC voltage that can affect other equipment on the same circuit.
HP Business Desktop PCs - Energy efficient power supplies, available today
HP offers a range of high energy efficient power supply options across our current 5000 and 7000 series Business Desktop PCs and select HP Workstations with efficiency ratings from 80% efficient up to 87% efficient. This translates into as much as a 34% increase in usable energy which saves you money and takes a small load off the environment.
Don't wait to start taking advantage of the many benefits of desktops with 80% efficient power supplies - get started today in helping your bottom line while helping the environment at the same time.
HP energy efficient power supplies have efficiency rating of 80%-87%.
**
Energy 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.
