Power Supply Efficiency Explained: Everything You Need to …
This is also a power supply efficiency rating, and it simply means that the PSU is at least 80 percent efficient at different workloads (which could be 20, 50, and 100 percent). However, most 80 plus power supplies are most efficient at 50 percent workloads (which we call the peak), as compared to very high or low workloads.
Power Supply Efficiency Rating Explained
A simple example would be if you have a 600W power supply with an efficiency rating of 50%. This would mean that to output the full 600W of power to the PC components the power supply would have to draw 1200W of power from the socket (50% efficiency). That is the simplest explanation of what an efficiency rating for power …
