The Fractal Design Tesla R2 is available in 500 W, 650 W, 800 W, and 1,000 W versions, all with the 80 Plus Gold certification. Let’s take a look at the 650 W model, which comes with a very nice price tag.
The 650 W model (and only this model) has two color options: black or white. We reviewed the black model.
This power supply is manufactured by ATNG, using the same platform used by the Rosewill FORTRESS-650. (They are not identical; we will point out the differences between the two throughout the review.)
The Fractal Design Tesla R2 650 W is 6.3” (160 mm) deep, using a 135 mm fan on its bottom. There is no technical information available. It is a ball-bearing model, according to Fractal Design.
This unit doesn’t have a modular cabling system. All cables use nylon sleeves that come from inside the unit. This power supply comes with the following cables:
- Main motherboard cable with a 20/24-pin connector, 21.6” (55 cm) long
- One cable with two ATX12V connectors that together form an EPS12V connector, 26.4” (67 cm) long
- One cable with two six/eight-pin connectors for video cards, 21.3” (54 cm) to the first connector, 3.9” (10 cm) between connectors
- One cable with three SATA power connectors, 21.3” (54 cm) to the first connector, 5.1” (13 cm) between connectors
- One cable with three SATA power connectors, 16.5” (42 cm) to the first connector, 5.1” (13 cm) between connectors
- One cable with two standard peripheral power connectors and one floppy disk drive power connector, 22.8” (58 cm) to the first connector, 4.7” (12 cm) between connectors
All wires are 18 AWG, which is the correct gauge to be used.
The cable configuration is compatible with a mainstream 650 W unit; however, some competing products have four video card power connectors instead of only two, including the Rosewill FORTRESS-650.
