The Hiper Type-M 670W unit provided us with rather surprising results. We did not expect it to perform so flawlessly even under 100% load, neither deliver such efficiency results. All voltage lines are very strong and stay above spec even if the unit is loaded 100%. The voltage regulation circuit of the Type-M appears to be working quite well, effectively reducing large voltage fluctuations when there are aggressive power changes. The strongest voltage lines appear to be the 5V and 12V3 lines, which show the smallest difference between the lowest and highest voltage readings, while the weakest appears to be the 12V2 line, although with a mere 0.1V difference between the lowest and highest reading we simply cannot call it weak at all. Unfortunately for us, the overload protection of the unit works extremely well and shut down the unit instantly when placing more than 700W load on its lines, so it did not allow us to test the unit overloaded at all.

Unfortunately the sole 80mm fan used for the cooling of the unit also creates one of its drawbacks, which is noise. The Type-M is practically inaudible at 30% load, becomes audible between 50% and 75% load but when the unit is heavily loaded then noise becomes a problem. It won’t become annoying and perhaps it won’t bother anybody who doesn’t mind fan noise, but for those with sensitive ears it could be a nuisance. The thermal performance is very good too, proof of the efficiency that it provides. The chassis stays barely warm under all load conditions, because of the fan which speeds up to maintain a proper operating temperature.
