ModXStream Pro is a power supply series from OCZ featuring a modular cabling system and a very attractive price tag, at this moment featuring 500 W, 600 W and 700 W models, with the manufacturer promising that these units can deliver their labeled wattage at 40° C. Let’s see if the 600 W version is a good pick.

OCZ ModXStream Pro 600 W is 6 ¼” (160 mm) deep, using a 135 mm fan on its bottom and featuring active PFC circuit, of course.

The modular cabling system present on the 600 W model has six connectors, two red for the video card cables and four black for the SATA and peripheral power cables. The main motherboard cable, one ATX12V cable and one EPS12V cable are permanently attached to the power supply. They all have a nylon protection that comes from inside the unit. The cables included are:

• Main motherboard cable with a 20/24-pin connector, 17 ¾” (45 cm) long (permanently attached to the power supply).
• One cable with one ATX12V connector, 18 1/8” (46 cm) long (permanently attached to the power supply).
• One cable with one EPS12V connector, 18 1/8” (46 cm) long (permanently attached to the power supply).
• One cable with one six-pin connector for video cards, 18 1/8” (46 cm) long.
• One cable with one six/eight-pin connector for video cards, 18 1/8” (46 cm) long.
• Two cables with three SATA power connectors each, 18 1/8” (46 cm) to the first connector, 6 ¼” (160 mm) between connectors.
• Two cables with two standard peripheral power connectors and one floppy disk drive power connector, 18 1/8” (46 cm) to the first connector, 5 7/8” (15 cm) between connectors.

This configuration is satisfactory for a 600 W product.

All cables use 18 AWG wires, which is the minimum recommended, except the +3.3 V (orange) wires from the main motherboard cable, which are thicker (16 AWG).
