Hiper Power Type M 780W Review
 

The packaging and literature included with the Hiper Power Type M 780W make no mention of the 80 Plus Bronze certification claimed on the Hiper Group website. The only claim made is an efficiency of up to 85%. You will see from the figures given above that the power supply efficiency at no time exceeds 82%, and the claims of 85% on the Hiper Group website are not reached. A maximum efficiency of only 79% on 110VAC and 82% on 230VAC is a little dissapointing taken in context with the claimed 80 Plus Bronze certification, but they are still quite good and easily meet the requirements of the ATX12V specification.
