Collectors of low-noise PC knows that a radical solution to the problem of high noise level in the cooling system is getting rid of the fans. In the case of power supply, this approach is in conflict with the nature of the component, designed to provide energy for the rest of computer.
As can be seen in photographs from Enermax, generously perforated section of blocks, and the most power-full components are attached to the massive heat sink.
Judging from the images in the PSU are used modular cable system.
Range of power supply units Enermax with passive cooling includes models up to 650 watts. This power will be enough not only for the computer, which acts as a central component of home theater , but for a gaming system.
