Silencer Mk II is the latest power supply series from PC Power & Cooling, featuring a synchronous design with DC-DC conversion, single +12 V rail, 80 Plus Silver certification and an amazing 7-year warranty. Let’s see if the 750 W model is a good option.
As far as we can tell this unit is manufactured by Highpower.
The PC Power & Cooling Silencer Mk II 750 W is 6 19/64” (160 mm) deep, using a 135 mm fan on its bottom. This fan is a Globe Fan RL4Z-B1352512H, which is a ball-bearing fan with a maximum rotation of 1,500 rpm and a maximum airflow of 106.86 cfm.
This unit features active PFC, of course, and following PC Power & Cooling tradition, it doesn’t come with a modular cabling system. In fact, OCZ, the owner of PC Power & Cooling, decided to keep units with a single +12 V rail and no modular cabling system under PC Power & Cooling brand, while selling power supplies with modular cabling systems and multiple +12 V rails under their own brand.
The cables included are the following:
- Main motherboard cable with a 20/24-pin connector, 19 ¾” (50 cm) long
- One cable with one ATX12V connector, 23 5/8” (60 cm) long
- One cable with one EPS12V connector, 23 5/8” (60 cm) long
- Two cables with one six-pin auxiliary power connector for video cards each, 19 ¼” (49 cm) long
- Two cables with one six/eight-pin auxiliary power connector for video cards each, 19 ¼” (49 cm) long
- Two cables with four SATA power connectors each, 20 7/8” (53 cm) to the first connector, 5 1/8” (13 cm) between connectors
- One cable with four standard peripheral power connectors, 17 ¾” (45 cm) to the first connector, 5 1/8” (13 cm) between connectors
- One cable with three standard peripheral power connectors and one floppy disk drive power connector, 17 ¾” (45 cm) to the first connector, 5 1/8” (13 cm) between connectors
All wires are 18 AWG, except the +3.3 V (orange) wire on the main motherboard cable, which is thicker (16 AWG).
The cable configuration is perfect for a 750 W product, supporting two very high-end video cards that require two power connectors each, and we liked that the cables are long and each video card power connector is installed on an individual cable.
