PC Power & Cooling Silencer 610: A legend reviewed

Viewing page 2 of 4 pages. Previous 1 2 3 4 Next


The Silencer 610 is painted matte black; no fancy gimmicks here. There are very few markings on the exterior; only the necessary stickers are visible. Aside from the fan exhaust and intake vents, there are some slots on one side through which air could flow. A large coil and power components on a small heatsink are visible through the six slots on the side. It's to help cool these components that this extra intake is here. The intake slots opposite the fan look like they would not impede airflow.

Matte black finish, slot intakes on the back and a small one on the side.

It's interesting to note that the unit is somewhat longer than normal. Opening up the PSU shows why: There's extra space between the fan and other components, ostensibly to reduce turbulence noise from having impedances too close to the fan blades. There's some merit to this approach, but much depends on fan speed. If it's spinning madly, any 80mm fan will still make a lot of noise. Most of the smaller capacitors visible in the photo below are rated at 105°C. The main capacitor in between the two big heatsinks is rated for 85°C, which is probably fine as it is smack in the middle of the airflow path.

Additional space between the fan and any impedance on its intake side helps reduce turbulence noise.

From another angle, the big heatsinks look quite familiar. In fact, the entire circuit board and its components look extremely familiar. They look almost identical to the innards of another PSU line of the same name, now long discontinued: The Seasonic Super Silencer models, produced in 2003 and 2004. Follow the provided link to our review of the Super Silencer 400, and you'll see heatsinks of the same design and size. In examining the details of the transformers, coils and capacitor types used, it is impossible to ignore the similarities. There seems little doubt that this product does indeed come from one of Seasonic's factories, and that the design owes something to the Super Silencers. That this should be the case is hardly a surprise. The number of relationships between the various PSU brands and the companies that manufacture the PSUs is as complex and convoluted as in any other industry.

Large, heavy looking... and familiar heatsinks.

The small heatsink on this side holds a FET or voltage regular that obviously gets hot.
It's where the small vent slots on the side is located.

The ADDA fan is a high speed ball-bearing model rated for 55CFM at 12V.
Not ideal for low noise, but the fan controller also plays a big part in acoustics.


The Silencer 610 has many long output cables. They may pose a challenge to manage well in a medium or smaller case.

  • 19" cable for the main 20+4-pin ATX connector
  • 21" cable for the 4-pin AUX12V connector
  • 22" cable for the 8-pin AUX12V connector
  • 22" cable with one 16X 6-pin PCI-e connector
  • 22" cable with one 16X 6/8-pin PCI-e connector
  • 25" cable with two 4-pin IDE drive connectors and one floppy drive connector
  • 31" cable with three 4-pin IDE drive connectors
  • 37" cable with three 4-pin IDE drive connectors
  • 37" cable with three SATA drive connectors
  • 31" cable with three SATA drive connectors
