Seasonic Prime TX-1600 Noctua Edition (2024)

Launched November 25, 2024, the Prime TX-1600 Noctua Edition is a co-developed variant of Seasonic’s flagship PRIME TX family, updated for ATX 3.1/PCIe 5.1 with native 12V‑2×6 cabling.Sourceseasonic.com↗

This is a flagship-tier, 1600 W, fully modular ATX unit that exists to quietly power extreme GPUs and workstation-class rigs with ample headroom. It’s well-suited to high-end GPU builds and overclocked systems that need native next‑gen GPU connectors, Titanium efficiency, and a long 12‑year warranty; note the 210 mm length requires a roomy ATX case. Notable: it uses Noctua’s NF‑A12x25 fan plus a custom grille and carries a Cybenetics Lambda A++ noise rating; Seasonic lists it as sold exclusively by Noctua. Not discontinued as of September 28, 2026.Sourceseasonic.com↗
