Seasonic's Prime Titanium PSUs are the Prime family's flagships, and the 1kW model we're reviewing today is the strongest Seasonic PSU with 80 PLUS Titanium efficiency and an incredibly quiet fan.

So why even bother with digital platforms? The reason is simple. After so many years of development, and with engineers so accustomed to analog circuits, it's only natural to see masterpieces like the Prime platform. But there isn't any room left to extract better performance or higher efficiency from analog circuits; they've reached their limits. If we want to see more than 94% overall efficiency, then there is no other solution except digital circuits along with GaN FETs and Totem-pole PFC converters, which enable lower energy losses.
