A Closer Look – Interior
The unit is manufactured by Seasonic and OEM produced for Antec. It is based on the SeaSonic S12II 620.
The unit has an ADDA 135mm fan with dual ball bearings and the part number ADN512MB-A90.
The rear AC input has EMI/transient filtering on a small PCB with one X and four Y capacitors as well as a coil.
The PCB features additional filtering components and coils.
The main capacitor is a Nippon Chemi-Con part rated for 85°C, 560 μF, 400 V.
Black passive heatsinks are strategically placed throughout the unit for heat-disippation. We can see lots more Nippon Chemi-Con filtering capacitors dotted around these heatsinks and these are rated for 105 degrees.
There is a vertical PCB providing the PFC/PWM controls.
There is a separate PCB for the modular connectors, each block with capacitors for additional regulation and filtering.
