Amacrox Free Style 85PLUS 650 W is 6 ½” (16.5 cm) deep, having a 120 mm fan on its bottom, active PFC and a modular cabling system, with some cables being permanently attached to the power supply – these cables use a nylon protection that comes from inside the unit. The cables included on Free Style 85PLUS 650 W are:

• Main motherboard cable with a 20/24-pin connector (permanently attached to the power supply) (19 ¾” or 50 cm).
• One cable with two ATX12V connectors that together form an EPS12V connector (permanently attached to the power supply) (21 ½” or 55 cm).
• One cable with one six/eight-pin power connector for video cards (permanently attached to the power supply) (21 ½” or 55 cm).
• One cable with one six/eight-pin power connector for video cards (modular cabling system) (17 ½” or 44.5 cm).
• Two cables with four SATA power connectors each (modular cabling system) (17 ½” or 44.5 cm to the first connector, 5 7/8” or 15 cm between connectors).
• Two cables with three standard peripheral power connectors each (modular cabling system) (17 ½” or 44.5 cm to the first connector, 5 7/8” or 15 cm between connectors).
• Two adapters to convert any peripheral power connector into a floppy disk drive power connector.

The number of cables is adequate for a 650 W product, and having eight SATA power connectors is really good. All wires are 18 AWG, which is the correct gauge to be used.
