When OCZ bought PC Power & Cooling, the company said that PC Power & Cooling power supplies wouldn’t have modular cabling systems. Well, scratch that. The latest release from the brand, the Silencer Mk III, features a modular cabling system and carries the 80 Plus Bronze certification, coming in 400 W, 500 W, and 600 W versions. Let’s test the 600 W version and see if it is a good choice.

The Silencer Mk III units are manufactured by Seasonic, and their internal design is different from the Silencer Mk II models.

The PC Power & Cooling Silencer Mk III 600 W is 6.3” (160 mm) deep, using a 120 mm ball bearing fan on its bottom (ADDA AD1212HB-A71GL).

As mentioned, this unit has a modular cabling system with six connectors, two for video cards or ATX12V/EPS12V power cables and four for peripheral and SATA power cables. Three cables are permanently attached to the power supply. This power supply comes with the following cables:

• Main motherboard cable with a 20/24-pin connector, 21.6” (55 cm) long, permanently attached to the power supply
• One cable with two ATX12V connectors that together form an EPS12V connector, 23.2” (59 cm) long, permanently attached to the power supply
• One cable with two ATX12V connectors that together form an EPS12V connector, 23.6” (60 cm) long, modular cabling system
• One cable with one six/eight-pin connector for video cards, 22” (56 cm) long, permanently attached to the power supply
• One cable with one six/eight-pin connector for video cards, 22.4” (57 cm) long, modular cabling system
• Two cables, each with three SATA power connectors, 16.5” (42 cm) to the first connector, 5.5” (14 cm) between connectors, modular cabling system
• One cable with three standard peripheral power connectors and one floppy disk drive power connector, 22.4” (57 cm) to the first connector, 5.1” (13 cm) between connectors, modular cabling system

All wires are 18 AWG, which is the minimum recommended gauge.

The cable configuration is fair for a 600 W power supply, with two video card power connectors and six SATA power connectors.
