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.

The power factor was maintained at or above 0.9 at all times, meeting the 80 Plus requirements, and sitting at or around 0.95 for what would be the average power consumption when installed in a PC.

Efficiency and power factor levels are satisfactory.  There is nothing out of the ordinary, but still an overal pass in this section.

 

AC Ripple On DC Outputs:

 

With no significant difference between the noise levels at 110VAC and 230VAC, the screenshots for 230VAC only are shown below.

The noise level on the 12V rail is very dissapointing, and at 130mV exceeds the maximum permissable of 120mV level in the ATX12V specification. This is very high for a power supply in this class, and unfortunately warrants a fail in this section. The noise levels on the 3V3, 5V0 and +5VSB are very good and the level on the -12V rail is satisfactory.
