Seasonic Brings its Latest PC and Server PSUs to Computex 2026

Seasonic is a major OEM of switching power supplies for computers of nearly every shape and size. The company showed off its OEM-channel PSUs targeting servers and workstations; reference PSUs, and some of the more premium PSU models that retail under its own channel brand. We begin our tour with the SIC-NRX522-22A63GT, a CRPS 54 V server PSU that meets 80 Plus Ruby efficiency standards, and offers 5200 W of continuous output for AI GPU servers.

Over in the client side, the company showed off its new smart PSU software, the Seasonic OptiGuard Dashboard. Some of the newer smart PSUs from Seasonic have Bluetooth connections. They pair with your machine as just another Bluetooth IoT device. The dashboard lets you monitor the PSU’s various parameters, including real-time output on the 12V-2×6, current per pin, and connector temperature. You don’t need a PC to use the OptiGuard app, Seasonic even released Android versions that you can use on smartphones and tablets. Seasonic managed to cram a whopping 1300 W of power into an SFX-L PSU, with the Focus SFX-L 1300 W.

The Prime Enterprise Opti line of PSUs target AI inferencing server builds. The series includes 1600 W and 1300 W variants. These offer 80 Plus Titanium and Cybenetics Titanium-rated switching efficiency, use SiC MOSFETs, and have active micro-tolerance load regulation. Both models offer two 12V-2×6 connectors.The company also showcased the Prime Enterprise Platinum series. These lack OptiGuard smart features, and are aimed more at AI inferencing builds with multiple GPUs. Variants in the series include 2800 W, 3000 W, and 3200 W; all four offer four 600 W 12V-2×6 connectors, 80 Plus Platinum and Cybenetics Platinum switching efficiency, and feature a Delta Electronics-sourced high-airflow 120 mm fan. There is a sub-series of Prime Enterprise Platinum targeting desktop builds; this comes in 1000 W and 1200 W variants.We spotted the company’s 2026 Core GX line of mainstream PSUs, which come in 850 W, 1000 W, and 1200 W variants, featuring a low depth of 14 cm, and an enhanced 7-year product warranty. You get 80 Plus Gold switching efficiency, ATX 3.1 + PCIe 5.1 CEM standards.
