Hiper Type-MII 5M730 PSU, efficiency graph

The Hipergroup Type-MII 730W unit is considerably improved over the first Type-M units we reviewed. The voltage regulation circuit works quite well and adjusts quickly to swift load changes, although it is interesting to note that some lines adjust smoothly and while others adjust more quickly and abruptly. Either way, it does not affect the performance of the unit itself or of the components, as long as the lines stay within specifications.

All of the 12V lines tend to slightly overvolt, which is a good thing as it will not reduce the lifespan of the components but it will slightly enhance the overall stability of the system. The peak power output of the unit is considerably above 730W. We managed to reach 950W maximum output during our testing, however if the unit is loaded with more than a 730W load it will shut down shortly afterwards.

Despite the use of a single 80mm fan, the unit manages to stay quiet when it is moderately loaded. It only becomes audible between 40% and 70% load, and moderately noisy afterwards. The much improved efficiency over the early Type-M units seems to help very much with that.

The thermal performance of the unit is above average, but not exceptional. Until 50%-60% load the unit will barely warm up, however above 80% load the fan speeds up considerably as the unit becomes quite hot. Although it is unlikely that this unit will be running at over 70% load even in very powerful systems, doing so might reduce its lifespan.
