Cooler Master Silent Pro M500 500W Modular PSU Review

Let us now come from the technical data to the optical and practical criteria. The black metal chassis looks nice and is very high-quality finished. At the power supply are the ATX/ATX 2.2 power cable and a 12V cable with two plugs for the CPU power attached and protected with black mesh plastic sleeves.

Here is again a picture with a bent view, where one can recognize the label and the lower fan.

The large 135mm 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 fan is very quiet and it is nearly impossible to hear the fan.

Here one can see the back of the power supply, where only the power switch and the socket for the 115V to 230V cable can be seen. Thanks to the good cooling over the 135mm fan another fan is not necessary on the power supply back. The small bore holes beneath the tapped holes are btw. for the contained silicon rubber pads. Both silicon pads can be pressed in the tapped holes at the front and the rear power supply side to reduce somewhat the vibration to the case.

The Cooler Master SX power pack is build modular, as already mentioned on the first page and provides thanks to individually connectable cables a cleared up PC for a better aeration and/or heat dissipation from the PC case. All connections are well finished and offer a safe contact.

The removable 4-Pol plug right of the ATX plug is not for the EPS 12Volt supply, but for the current usual ATX 2.2 motherboards with 24 pole current supply. In order to save the costs of additional adapters, the 20-pin plug (up to ATX 2.1) can be converted very simply to a 24-pol ATX plug. This is for some users a bit fiddly, but it is difficult to solve this in another way. On the left of the picture, one can see both 4-pin 12 Volt plugs for the CPU power.

A look inside of the power supply shows a good processing with high-quality components. Very special are the cooling fin inside of the Cooler Master power supply, which comprises of hybrid copper alloy and aluminium heatsink. The Japanese 105°C capacitors already achieve a higher durability than conventional 85°C Elcos, but an efficient cooling increase the durability again and lowers the necessary fan noise level.
