Honestly, the Silent Pro M isn’t the greatest power supply that we have ever tested but it is far from the worst. When running at the normal loads one would put on an 850W power supply it is actually very well behaved and exhibits passable voltage regulation and good ripple suppression. Unfortunately, things start falling apart when more is asked of it. Its fan speed profile is far too mundane which allows temperatures to rise to worrying levels and thus causes a rapid degradation of performance as load increases. Remember, this Cooler Master unit is only rated at 40°C so things can and will fall apart when internal temperatures reach 50°C+ like we saw.
There are however some resounding qualities here. It carries one of the best warranties we have seen at 5 years and also shows some of the best efficiency of all the 80Plus Bronze rated power supplies in this roundup. Performance isn’t everything and the flat cables Cooler Master used are perfect; they are done perfectly and will help you immeasurably when setting up a clean system. Pricing is also extremely good, especially if you are buying it in the United States.
If you are looking for an extremely inexpensive 850W power supply which you won’t be pushing with an ultra high end dual GPU setup, the Silent Pro M could be an option for you. Otherwise, there are better performing units out there which don’t cost all that much more.
Pros:
- Efficient
- Very well priced
- 5-year warranty
- Quiet until high loads
- Great flat cables
Cons:
- Disappointing performance at higher loads
- Gets extremely hot
