However, “This mark does not serve as a consumer information label, but rather demonstrates the performance of the EPS when tested to the internationally supported test methods.” Hmm. If the mark does not serve as a consumer information label, who is it for? Bragging mark (to other power supply manufacturers)? My power supply is marked “V.” This appears to be more stringent than “VI.” True?
