The Fractal Design Tesla R2 650 W proved to be a very good mainstream power supply with the 80 Plus certification, with an excellent price tag and, therefore, a recommended unit.
It is based on the same platform as the Rosewill FORTRESS-650. Rosewill’s version, however, uses slightly different components inside. Of note for the average user is the use of better capacitors, manufactured in Japan by Chemi-Con, and a total of four video card power connectors instead of only two. The model from Rosewill is also USD 10 cheaper.
