Cooler Master Silent Pro Hybrid 1050 PSU Review

Let us now come from the technical data to the optical and practical criteria. The black metal chassis has a good finish and makes a very good impression.

Here is a picture with a bent view of the Silent Pro Hybrid power supply without any cable-clew, because it’s fully modular:

The large 135 mm thermal regulated fan attached at the lower surface sucks the air flow into the power supply and blows the warmed up air without another fan through the small holes out of the power supply. The power supply power off the fan until up to approx. 200W load (fan control set to auto) and is also above this load very silent, so it’s nearly impossible to recognize the sound of the fan inside of a PC.

Thanks to the good cooling over the 135mm fan, another fan is not necessary on the power supply back. Here one can see the back of the power supply, where one can see only the power switch and the socket for the 90V to 264V cable:

As mentioned on the first page, the Cooler Master Silent Pro Hybrid PSU is build fully modular, so it’s possible to connect only necessary cables inside of the PC case to get a cleared up PC. This provides the best aeration and/or heat dissipation from the PC case to increase the hardware durability.

The angled SATA connector is as seen on some other PSUs unfavorably designed, since the rear cap can get off easily, whereby the contacts on the back of the plug are opened. Coolermaster showed with the plugs of their Silent Pro M500 PSU, how to solve this in a better way.

Anyway, the processing of the plug is still good, as you can see on the SATA plug.

The 24-pol ATX cable is protected with a black mesh plastic sleeve and can’t be anymore converted to a 20-pin plug (up to ATX 2.1) connector.

A look inside of the power supply shows a good processing and offers high-quality components. Very special designed are the heatsink fins inside of the Cooler Master power supply.

The high-quality 105°C capacitors achieve a higher durability than conventional 85°C Elcos and the efficient cooling increases the durability again and lowers the necessary fan noise level.

This small fan control is also included, which allows in manual mode to control the internal 135 mm PSU fan with the left poti and up to three fans in the PC chassis can be adjusted with the right poti.

Here you can see the back of the fan control, where the outputs of the 3-pin or 4-pin (3/4-pin adapter cable supplied) at our test sample of 3.5 volts up to a maximum of only 9.95 Volt can be regulated. Instead of using the relatively simple LM317T voltage regulator, Cooler Master could use for example a poti with swith at the end point to switch from 10 volts up to the full 12 volts. But the fan control rather can be seen as an additional addon, so you can survive the low voltage selection range.

The processing of the simple fan control was overall well except the two soldering points of the two LEDs.
