Interestingly, PC Power & Cooling did not implement any type of seals on the Silencer 610W power supply. This means that, when we opened our particular unit up, we only unscrewed the necessary screws without breaking any particular warranty seals. It's quite a rare thing to see in power supplies.
Anyways, let's take a look at the insides of the PC Power & Cooling Silencer 610W power supply.
A shot at the back of the power supply -- the AC power input as well as the on/off switch is located on the other side. A ferrite bead (Black) can be seen above in the main power cable lead-in. A single ceramic capacitor, iron ferrite coil, as well as a metalized polyester capacitor are all packed behind the board. The PC Power & Cooling Silencer 610W automatically selects voltage, as mentioned earlier.
The parallel alignment of two aluminum heatsinks in the same direction of power supply orientation are one of the most prominent components inside the Silencer 610W. Many have observed the remarkable similarities with Seasonic power supplies with its interior -- including Seasonic built Corsair units with placement of internal components, such as the heatsink -- but there's no real confirmation whether the Silencer 610W is a Seasonic built unit, or a true PC Power & Cooling power supply.
In the above photo, we can see multiple iron ferrite coils covering the power supply's transient filtering stage in addition to the initial segment described earlier. Multiple ceramic capacitors can be seen above, as colored blue; as well as a metalized polyester capacitor located behind the ferrite coils on the right.
The main capacitor in the Silencer 610W is a Nippon Chemicon electrolyte unit located between the two heatsinks; rated for up to 85 degrees Celsius.
The metal oxide varistor (Orange-yellow) is located behind the metalized polyester capacitor (Yellow), and a fuse behind fireproof rubber -- located on the right of the metalized polyester capacitor.
Generally, the primary filtering stage is done very nicely with three ferrite coils and one located in with two sides in contact with a heatsink. The bracket design of the heatsink are designed with gaps at the top to strike a balance between heat dissipation and airflow.
The smaller OST capacitors are rated for usage up to 105 degrees Celsius, as juxtaposed to the Japanese Nippon Chemicon capacitor designed for usage at up to 85 degrees Celsius.
What about the date again? ;)
One of the biggest design aspects when it comes to the PCP&C Silencer 610W power supply is the gap left between the internal components and the fan itself. At the back is a single 80mm ADDA fan we've seen used in many Seasonic power supplies; where we measured four centimeters of room between the fan inlet and the closest of the two parallel aluminum heatsink. This is why the PC Power & Cooling Silencer 610W is longer than majority of PSUs.
The primary cause of system noise affected by airflow of fan is air turbulence caused by close range fan airflow obstructions regarding on the intake side. With power supplies, this effect is typically a result of lessened airflow due to complex and tight interior design with components such as heatsinks (Especially large solid ones as seen in the Silencer 610W); but are also affected by other components such as capacitors. The company also makes the claim that "the impact on the blades creates a discrete, high frequency tone that’s particularly annoying and up to 10dB louder than non-turbulent air".
