PC Power & Cooling are using the Adda AD1212HB-A71GL fan (120mm ball bearing), which we have seen used in several other quality power supply designs. They are using a partial plastic cover to specifically direct air towards the front of the power supply.
The power supply is based on a Seasonic branded design. It is exceptionally clean internally with careful attention to design detail.
The unit uses four Y capacitors, a single X capacitor and a coil. On the main board are two more ferrite coils, another X capacitor, two Y capacitors and an MOV. They are using a 105c rated Chemi Con capacitor for the primary side with the PWM/PFC controller offset to the left. We noticed other Chemi Con capacitors throughout the design, even on the modular board at the rear.
The cables are fully sleeved inside the chassis to help prevent fraying over time.PC Power & Cooling Silencer MK III 600W Power Supply Review,
