XFX may be a newcomer on the power supply market, but so far the other two models from them we reviewed, 650 W XXX Edition and 850 W Black Edition proved to be outstanding products. Let’s see if their latest model, 750 W Black Edition, follows the same path.

Like 850 W Black Edition, the 750 W version is manufactured by Seasonic and, in fact, it is a relabeled Seasonic M12D, which proved to be one of the best 750 W power supplies on the market today. Therefore XFX 750 W Black Edition enters the market to fight against this model from Seasonic and Corsair HX750W, as they all use a DC-DC design, i.e., the power supply is basically a +12 V model, with +5 V and +3.3 V outputs being produced by two smaller power supplies attached to the power supply main +12 V rail.

XFX 750 W Black Edition isn’t a long power supply, being 6 19/64” (160 mm) deep, using a 135 mm fan on its bottom and featuring active PFC, of course.

The reviewed power supply has a modular cabling system with eight connectors (two for video cards and six for SATA/peripheral cables) and it comes with five cables permanently attached to the unit. This cables included are the following:

• Main motherboard cable with a 20/24-pin connector, 20 ½” (52 cm) long (permanently attached to the power supply).
• One cable with two ATX12V connectors that together form an EPS12V connector, 20 7/8” (53 cm) long (permanently attached to the power supply).
• One cable with one EPS12V connector, 20 7/8” (53 cm) long (permanently attached to the power supply).
• Four cables with one six/eight-pin auxiliary power connector for video cards each, 22 7/8” (58 cm) long (two permanently attached to the power supply and two on the modular cabling system).
• Three cables with three SATA power connectors each, 14 ¼” (36 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• One cable with two SATA power connectors, 14 ¼” (36 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• Two cables with three standard peripheral power connectors each, 14 ¼” (36 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• One cable with two standard peripheral power connectors, 14 ¼” (36 cm) to the first connector, 5 7/8” (15 cm) between connectors (modular cabling system).
• One adapter for converting one standard peripheral power connector into two floppy disk drive power connectors.

The main motherboard cable, the CPU cable (ATX12V/EPS12V) and the video card cables use thicker 16 AWG wires, which is excellent. SATA and peripheral cables use 18 AWG wires.

The number of cables is terrific for the high-end user, supporting two very high-end video cards that require two power connectors each.

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