Yes. what is efficiency has to do with psus?? said: what is efficiency has to do with psus?? The higher the efficiency, the less electricity is wasted as heat, the lower the actual electricity drawn from the A/C outlet will be. Example: All the component in a PC will draw a total of 300w at full load. PSU #1: 70% Efficiency - Actual power draw from A/C outlet = 300w/70% = 428.5w = 128.5w wasted as heat. PSU #2: 85% Efficiency - Actual power draw from A/C outlet = 300w/85% = 352.9w = 52.9w wasted as heat. slightly lower electricity bill too. Can't find your answer ? Ask !
