Seasonic has achieved the first 80 Plus Ruby certification for an ATX power supply tested at 115 V with its PRIME ENTERPRISE RX-1600. This 1600-watt model is designed for high-end desktops, professional workstations, and intensive GPU or AI-driven workloads.
The Ruby tier represents the highest efficiency level in the 80 Plus program. To qualify at 115 V, units must reach 85% efficiency at 5% load and 95% at 50% load. The RX-1600 met all CLEAResult requirements, including a power factor of 0.95 at 20% capacity.
This milestone continues Seasonic's history of efficiency leadership, following its first Gold certification in 2008. While the RX-1600 sets a new benchmark for power delivery, the company has not yet released specific pricing or retail availability details.
