XFX is releasing their Pro series of power supplies, with single +12 V rail, DC-DC secondary design, and 80 Plus Bronze certification. So far three models were released: 650 W, 750 W, and 850 W. Let’s see how the 650 W model fared in our tests.
Like other power supplies from XFX, members of the Pro series are manufactured by Seasonic.
The XFX PRO 650 W is 6.7” (170 mm) deep, with a 135 mm dual ball bearing fan (ADDA ADN512UB-A90) on its bottom part.
The new XFX PRO 650 W doesn’t have a modular cabling system. All cables are protected with nylon sleeves. The power supply comes with the following cables:
- Main motherboard cable with a 20/24-pin connector, 22.4” (57 cm) long
- One cable with two ATX12V connectors that together form an EPS12V connector, 23.6” (60 cm) long
- Two cables with one six-pin connector for video cards each, 22.4” (57 cm) long
- Two cables with one six/eight-pin connector for video cards each, 22.4” (57 cm) long
- Two cables with four SATA power connectors each, 14.2” (36 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with four standard peripheral power connectors, 15” (38 cm) to the first connector, 5.9” (15 cm) between connectors
- One cable with three standard peripheral power connectors and one floppy disk drive power connector, 15” (38 cm) to the first connector, 5.9” (15 cm) between connectors
All wires are 18 AWG, which is the minimum recommended gauge.
The number of cables and connectors is simply fantastic for a 650 W product, since many manufacturers don’t add four video card power cables or a high number of SATA connectors on 650 W units.
