Seasonic Debuts First Power Supply With Stringent 80 Plus Ruby Rating
Seasonic has officially launched its first power supply unit to carry the stringent 80 PLUS Ruby certification. Introduced by CLEAResult last May, the 80 PLUS Ruby tier sets the most demanding efficiency requirements in the industry. While no units were available at launch, Seasonic PRIME ENTERPRISE RX-1600 is now confirmed as the first to meet these exacting standards.
What Changed and Why It Matters
The new unit, the Seasonic PRIME ENTERPRISE RX-1600, is described by the manufacturer as a high-wattage ATX power supply designed for demanding desktop, workstation, and AI systems. As the name suggests, it delivers 1600 watts of power, though full specifications remain unreleased.

The defining feature of the 80 PLUS Ruby standard is its requirement for specific efficiency ratings at a mere 5% load level. This is notable because low-load scenarios are notoriously difficult to optimize compared to high-load conditions. By mandating efficiency even when the system is barely drawing power, the new standard pushes manufacturers to improve performance across the entire load spectrum.
Seasonic's RX-1600 reportedly exceeds 80 PLUS Ruby specifications by a significant margin at every load level. However, detailed technical data sheets and independent benchmark results are not yet available for public review.
Pricing and Availability
At this stage, there is no confirmed pricing or release date for the Seasonic PRIME ENTERPRISE RX-1600. The official product page currently lists technical specifications as "Arriving Shortly." We will update this report if Seasonic releases further details regarding cost or regional availability.

The introduction of the 80 PLUS Ruby certification marks a significant step forward in power supply efficiency standards, moving beyond the traditional Bronze, Silver, Gold, and Platinum tiers. This development highlights the growing industry focus on energy optimization for high-performance computing platforms.
