Overview 
NEW IN PRIME ULTRA 

Seasonic has included a PSU tester in the box that will let consumers perform 
a quick and easy jump start on the power supply. Each PRIME Ultra Series power 
supply will also ship with a SATA 3.3 adapter to support the “Power Disable” 
(PWDIS) feature of the newer, high-capacity hard drives. The inline capacitors 
on the cables were removed, which takes away the bulkiness inside the system. To 
maximize flexibility, the 180-degree SATA connectors ensuring more flexibility 
and easier installation.
80 PLUS® GOLD

The PRIME Gold Series achieves 80 PLUS Gold certification with its 90 % 
efficiency at 50 % system load.
MICRO TOLERANCE LOAD REGULATION

Seasonic’s latest design keeps the output voltage within a very tight range, 
achieving under 0.5 % load regulation. This impressive electrical performance 
and stability makes this power supply an ideal choice for high-performance 
systems.

PREMIUM HYBRID FAN CONTROL

Seasonic’s vast experience in designing the most silent and efficient power 
supplies on the market was translated into the development of Hybrid Mode; a 
state-of-the-art fan control that enables users to keep the overall fan noise at 
the lowest possible level.
FLUID DYNAMIC FAN BEARING
High performance Fluid Dynamic Bearing (FDB) fans are designed to take 
advantage of the impact absorbance effects of oil. They are extremely reliable 
and generate considerably less operating noise and heat than ball bearing fans. 
The lubrication of the bearing surface reduces friction and vibration and 
therefore lowers overall power consumption. Due to the effortless, quieter 
rotations and its robust construction, this reliable fan technology also greatly 
increases the lifespan of the fan.
HOW IT WORKS
When the fan shaft rotates, high pressure oil drifts along the grooves of the 
bearing sleeve to generate a thin layer of lubrication between the bearing 
faces. As the speed increases, so does dynamic oil pressure and the shaft is 
lifted from the bearing to create smooth, effortless rotations. The herringbone 
shape of the groves helps to efficiently channel the lubricant and avert 
leakage.

CABLE-FREE CONNECTION DESIGN

Seasonic’s engineers have implemented a new design feature, where instead of 
cables; the back panel and the PCB (Printed Circuit Board) are connected by a 
copper plate. This breakthrough solution not only lowers the chance of 
production errors during manual insertion but it also improves output power 
quality.
