Tacens announced the sixth-generation of its Radix series power supplies. The series includes 550W, 650W, 750W, and 850W models; all of which feature single +12V rail designs, and over 85% efficiency (according to the company), making them 80 Plus Bronze eligible. The 550W variant features a single 6+2 pin PCIe power connector, the 650W and 750W models feature two, and the 850W model features four. All four are cooled by 140 mm Aura Pro fans. In addition to the four standard Radix ATX v2.3 PSUs, Tacens also introduced two Radix Eco series PSU models, 500W and 400W. The Radix Eco 500W sticks to the standard ATX form-factor, while the 400W model is built in the SFF ATX form-factor. Both Eco models lack PCIe power connectors.
