Seasonic has become the first manufacturer to earn 80 Plus Ruby certification for an ATX power supply tested at 115 V. The Seasonic PRIME ENTERPRISE RX-1600, a high-wattage ATX power supply designed for demanding desktop, workstation, and AI systems, meets the program's highest efficiency tier.

Seasonic has a long history of firsts in the 80 Plus program. In 2005, Seasonic became the first power supply manufacturer to certify products under the program's rigorous criteria with the Seasonic SS-400HT, and the first to bring a complete family of four certified products to market that same year. In 2008, Seasonic was again the first to achieve 80 Plus Gold certification.

"Seasonic has been involved with 80 Plus since the program's launch, so this result is significant for us," said Walter Sun, CEO of Seasonic. "Our first certified PC power supply appeared in 2005, followed by the first Gold certification in 2008."

Ruby is the newest and most demanding tier in the 80 Plus program, which is administered by CLEAResult. To earn Ruby certification, a power supply tested at 115 V must achieve 85% efficiency at 5% load, 91% efficiency at 10% load, 93% efficiency at 20% load, 95% efficiency at 50% load, and 91% efficiency at 100% load. The inclusion of 5% and 10% load points is significant, requiring advances across the full platform including switching control, thermal design, component selection, and validation.
