PC Power & Cooling Silencer 910 Power Supply Review

Introduction
Hardware Secrets Golden Award

PC Power & Cooling Silencer 910 uses internally the same design as Seasonic M12D, thus being manufactured by Seasonic. This design is based on a DC-DC converter on the secondary, i.e., Silencer 910 is basically a +12 V power supply with two small power supplies in charging of converting the +12 V output into +5 V and +3,3 V. This is the same concept used on power supplies series like Signature and TruePower New from Antec, M12D from Seasonic, UCP from Cooler Master and HX (750 W and above) from Corsair. These other models proved to have an above-the-average efficiency. It is important to keep in mind that other models from PC Power & Cooling Silencer series use a different internal design. Let’s see how the performance from PC Power & Cooling Silencer 910 is.

Silencer 910 is 80 Plus Silver certified, meaning it has a minimum efficiency of 85% under light load (20% load, i.e., 182 W) and under full load (910 W) and a minimum efficiency of 88% under typical load (50% load, i.e., 455 W).

PC Power & Cooling Silencer 910 is 7 1/8” (180 mm) deep, using a small 80 mm fan on its rear instead of a big 120 mm or bigger fan on its bottom, and featuring active PFC, of course. It doesn’t have a modular cabling system, being the main difference between Silencer 910 and Seasonic M12D series.

The cables that come with Silencer 910 are the following:

  • Main motherboard cable with a 20/24-pin connector (18 ½” or 47 cm in length).
  • One cable with two ATX12V connectors that together form an EPS12V connector (22 1/2” or 57 cm in length).
  • One cable with one EPS12V connector (23 5/8” or 60 cm in length).
  • Two auxiliary power cables for video cards with one six-pin connector each (22 1/2” or 57 cm in length).
  • Two auxiliary power cables for video cards with one six/eight-pin connector each (22 1/2” or 57 cm in length).
  • One SATA power cable with four connectors measuring 14 ½” (37 cm) between the power supply and the first connector and 6” (15 cm) between connectors.
  • One SATA power cable with four connectors measuring 19 3/4” (50 cm) between the power supply and the first connector and 6” (15 cm) between connectors.
  • One SATA power cable with four connectors measuring 24 7/8” (63 cm) between the power supply and the first connector and 6” (15 cm) between connectors.
  • One cable with three standard peripheral power connectors and one floppy disk drive power connector measuring 17” (43 cm) between the power supply and the first connector and 5 1/8” (13 cm) between connectors.
  • One cable with four standard peripheral power connectors measuring 24” (61 cm) between the power supply and the first connector and 5 1/8” (13 cm) between connectors.

Usually on power supplies all cables have the same length, what doesn’t happen with Silencer 910. All wires are 18 WG, with the wires used on the main motherboard cable being thicker (16 AWG), which is great to see.

We think this power supply could have at least two extra cables for video cards. Since it is clearly targeted to high-end systems, it should bring direct support for SLI and CrossFire configurations using three high-end video cards, which is not the case. With only four video card connectors you can install up to two high-end video cards, since each video card requires two power connectors. You can install more than two video cards converting standard peripheral power plugs into video card auxiliary power connectors, though.

Now let’s take an in-depth look inside this power supply.
