On the consumer front, Seasonic has new Focus SFX-L power supplies, offering modular cables, up to 1300W capacity and 80Plus Gold efficiency, along with ATX 3.1 and PCIe 5.1 compliancy. There are also full-sized ATX versions of the Focus power supply, offering capacities up to 1000W with 80Plus Platinum efficiency.

The Seasonic Core series is where gamers will go for a cheaper full-sized option while keeping 80Plus Gold efficiency. If you need a bit more power than that, then a Seasonic Vertex is your point of call, offering the same efficiency rating, but bumping capacities up to 1200W.

If you want something that looks a bit different, there is a limited edition ‘Sakura' version of the Focus GX-1000, although we don't know exactly how globally available these units will be.

Seasonic Prime has always been the flagship and that continues to be true today. The new Prime Enterprise models promise capacities all the way up to 3200W, intended to power high-end workstations and AI systems, although you will have to deal with only having two native 12V-2×6 connectors on most models.

The Seasonic Prime Enterprise series also stands out for its EDPP protection features. Essentially, in AI-ready multi-GPU systems, there can be sudden and repeated power changes. EDPP creates stricter dynamic load validation to ensure power delivery remains stable during scenarios like this.

Moving further into the enterprise segment, Seasonic also has a 5200W PSU here for AI systems, including an extremely rare 80Plus Ruby efficiency rating.

Following on from a preview last year, Seasonic has also showed the latest improvements to its new OptiGuard technology. These are new ‘smart' cables for 12V-2×6 equipped graphics cards, allowing per-pin monitoring for load and giving warnings if there is an issue, so you can power down the system safely and check that the connector is seated properly to avoid disaster.
