Its 80 PLUS Gold efficiency and active PFC describe its power conversion features. Fully modular cables let you connect the lines a build needs, and the 135 mm FDB fan provides cooling. The housing measures 160 × 150 × 86 mm (D × W × H).
Inside, an LLC half-bridge converter works with DC-to-DC technology and Japanese main capacitors. The listed cable connections are one 16-pin PCIe Gen 5, two 8-pin EPS (4+4), two 8-pin PCIe (6+2), 12 SATA and four MOLEX connectors. This range supports desktop builds that need modular connections and PCIe Gen 5 support.
