XFX is releasing a new series of power supplies with the 80 Plus Gold certification and a fully modular cabling system, with 750 W, 850 W, 1,050 W, and 1,250 W versions, dubbed the PRO Black Edition Full Modular. Be aware that the name “PRO Black Edition” has already been used by XFX for an 80 Plus Bronze power supply series, and the new series has the “Full Modular” words added to its name. (The new models have the letters “BEF” added at the end of their part numbers.) Wouldn’t it be simpler to just use a different name? Anyway, let’s see if the 750 W version deserves our recommendation.
The XFX PRO 750 W Black Edition Full Modular is 6.3” (160 mm) deep. It uses a 120 mm ball-bearing fan on its bottom (ADDA AD1212MB-A70GL; models from Seasonic and Corsair based on the same platform use a fan from Sanyo Denki). The power supply has a “hybrid/normal” switch that allows you to configure the fan to turn on only when the power supply load reaches 30% of the unit’s labeled wattage (i.e., 195 W), so the power supply won’t make any noise when the computer doesn’t demand a lot of power. Under the “hybrid” mode, between 30% and 50% load, the fan will spin at a lower speed, generating lower noise than usual.
The modular cabling system from this power supply has 13 connectors: two for the main motherboard power connector, six for video card and ATX12V/EPS12V connectors, and five for peripheral and SATA connectors. This power supply comes with the following cables:
- Main motherboard cable with a 20/24-pin connector, 23.6” (60 cm) long
- One cable with two ATX12V connectors that together form an EPS12V connector, 25.6” (65 cm) long
- One cable with one EPS12V connector, 25.6” (65 cm) long
- Two cables, each with two six/eight-pin connectors for video cards, 22” (56 cm) to the first connector, 4.3” (11 cm) between connectors
- Two cables, each with four SATA power connectors, 15.7” (40 cm) to the first connector, 4.7” (12 cm) between connectors
- One cable with two SATA power connectors, 11.8” (30 cm) to the first connector, 4.7” (12 cm) between connectors
- One cable with three peripheral power connectors, 15.7” (40 cm) to the first connector, 4.7” (12 cm) between connectors
- One cable with two peripheral power connectors, 11.8” (30 cm) to the first connector, 4.7” (12 cm) between connectors
- One adapter to convert a standard peripheral power connector into a floppy disk drive power connector
All wires are 18 AWG, which is the minimum recommended gauge.
The number of connectors is adequate for a 750 W power supply, allowing you to install up to two high-end video cards that require two auxiliary power connectors each. This is the same cable configuration found on the Seasonic X-Series KM3 650 W.
Let’s now take an in-depth look inside this power supply.
