Energy Usage Research on Computer Power Supplies

Although there are many articles and published papers on energy consumption related to computer equipment, it’s almost impossible to find detailed specifications of this equipment. 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.
Please note: More devices are added monthly, so please make sure to keep tuning in.
