Enermax are using a 135mm ZIC Fan. This is a double ball bearing design rated at 12V, 0.45A – model number ZFB132512H. We haven't had many experiences with this particular brand. Enermax have attached a small plastic shield on one side – this forcibly redirects air flow over specific high output and heatsinks of the power supply underneath.
Enermax are using RSY as a partner for the design of this power supply. We know RSY were involved with other companies in the past such as Seasonic and Super Flower, but it is not often we see one of their designs in a unit we test. This platform is new and worth some discussion. It is delivering two standby rails at the same time. This is due to the ATX12VO and ATX12V implementations in the design. As you may have noticed earlier in the review on the power supply readout table, the unit is set up as a standard unit, but one that also outputs only 12VSB and 12V.
The internal design of this power supply is clean with plenty of space between component for good air flow and the soldering quality throughout is really very good. The 12V FETs are installed on a vertical PCB, close to the main transformer. There are DC-DC convertors which generate the minor rails in this area as well.
It is also reassuring to see high grade capacitors from Japanese companies such as Rubycon and Nippon Chemi Con throughout the design. There are some polymer caps as well, to help with ripple filtering across the secondary stage.
