Energy Usage Research on Desktop Computers

Information

Although there are many articles and published papers on energy consumption related to computer equipment and electronic devices, it’s almost impossible to find detailed or exact energy usage profiles based on environment, type of use and specifications. Here, you will find both: actual measurements (not averages or estimates) and also the specifications of the devices, which can help with comparison and identification.

Why these measurements are Useful and Important

For IT / Engineers – They can assist with Wattage or energy calculations for complex or basic systems, where battery backups (UPS), heat dissipation / cooling, and purchasing considerations can be made by using the observed energy profiles.
Off-The-Grid Enthusiasts – For those who love to play around with Generators, Inverters, Solar panels and batteries. Knowing the energy consumption will help you with calculations.
Homeowners – Learn and understand what your devices are doing and how it will affect your power bill. In the energy profiles for desktop computers page, you can clearly see how some devices that are off use quite a bit of energy. Also, a computer infected with a Virus will use almost 2.5 times as much energy when the CPU runs at 100%.
Environmentalists – Being conscious about how we use our devices and making small adjustments to our behaviors, such as the electronics we buy, how we use them, how we maintain them, or being aware of the different technologies that are environmentally friendly and have low energy usage, can have a great impact on the environment.

Please note: More devices are added monthly, so please make sure to keep tuning in.

Parameters

List of Research Articles:
– Desktop Towers or CPUs (Slim, Full, Gaming, OEM, Mini PC, iMac, etc.)
– Laptops, Netbooks, Chromebooks, Surface Pro, Macbook, etc.
– LCD and CRT monitors, TVs and other types of display
– Networking Equipment: Switches, Routers, Firewalls, Access Points, Modems, etc.
– Power Supplies: Measured by themselves
– Other: IoT, External Hard Drives, Printers, Cable Boxes, Gaming Consoles, Phones, Cellphones charging, UPS battery Backups, etc.

Power meters used:
– P3 P4400 Kill A Watt
– Poniie PN200
– Seasonic Power Angel SSM-1508RA
* All meters confirmed to be within 1 Watt of each other

Testing Procedures:
– Devices with an Operating System (Desktops, Laptops, etc) were monitored in different states as the Operating System is able to use technology such as SpeedStep and Cool’N’Quiet. These modes in particular were measured:
* Within BIOS: No power saving technology implemented – Computer was left at BIOS screen
* Within OS – Balanced, Power Saver, or Degrade (XP): Windows is allowed to manage the processor speed as required by the OS – These are the names of power profiles as used by older and newer versions of Windows. The frequency may also be noted next to the power reading.
Note: When no power profile is specified, it is assumed Balanced or Power Saver is in use by default
* Within OS – None (XP) or High Performance: Windows applies no power saving technology and allows CPU to run at full speed
* Stand by or Hibernate – Computer set to sleep or standby typically using S3/S4 states
* Off: The computer has been completely shut down but still plugged into the wall
* Live CD – Helps to see a comparison between Windows and Linux Live CDs power consumption
* Benchmark – Performed with applications such as Prime95, HeavyLoad or CPU Stability Test; as a stress test is performed, this raises energy consumption of the computer to maximum
– For other Devices with no Operating System with power saving technology capabilities (TVs, Modems, Routers, etc), these were allowed to run and operate normally as the power measurement was taken
