Cooler Master Silent Pro M2 1500W PSU Conclusion
With the release of the Silent Pro M2 1500W power supply, Cooler Master entered a segment of the market where the company will not be facing much competition from other manufacturers. On the other hand however very few users actually need 1500 Watts, which is why there are very few units capable of reaching that kind of power output.
As competition is very scarce, there are very few products to compare against this particular unit. Considering the extremely long load range, the voltage regulation figures were remarkable and, even though with a ripple of 74mV the figure seems mediocre, ripple suppression also is excellent considering that the 12V line had to handle 114A at maximum load. It would be very hard to get better performance than this from a consumer-level product capable of supplying up to 1500 Watts worth of DC power. Efficiency wise, the 80Plus Silver certification is not really special nowadays but it surely is very good for a product with this kind of output.
When it comes to thermal performance and acoustics, the situation is more complex. That is because the Silent Pro M2 is being marketed as a low noise power supply; and a low noise power supply it is, until the load’s demand exceeds 1000W, after which point the fan’s speed starts increasing nearly geometrically. The end result is a power supply which is very quiet while the load remains below 60% but also excessively loud if the load exceeds 80% of the unit’s capacity. This kind of behavior is natural, considering that even though the thermal losses of the Silent Pro M2 are relatively low (it is 80Plus Silver certified anyway), even that low losses percentage translates to a huge amount of energy while the unit operates at 60%+ capacity.
Even though we imagine that aesthetics are not the first priority of someone purchasing a power supply with this kind of output, it definitely is an important factor for today’s enthusiasts. The dark, simplistic design of the Cooler Master Silent Pro M2 1500W creates a subtle appearance which should match nearly every system’s visual theme. However, we would rather every cable of the power supply to be black and flat or at least old-fashioned sleeved, since Cooler Master’s approach of making half of the wires all-black and leaving the other half colored and sleeved made the Silent Pro M2 looking worse, not better.
The price tag of $365.12 is certainly going to burn a small hole in the pocket of whoever decides to buy this power supply. Still, this price should be only a small fraction of the cost of the whole system, considering that a system which requires such a power supply is now worth several thousands of US dollars.
Legit Bottom Line: The CM Silent Pro M2 1500W Power Supply Unit is nothing short of a mini powerhouse, with a power output capable of feeding no less than six typical home PCs. Clearly, this is not a product meant for the average Joe user but reserved for those who are planning to build really extreme computers, such as Quad SLI dual CPU systems. If you do possess or plan on building such a system, you would find the overall performance of the Silent Pro M2 1500W power supply more than satisfactory.
