Seasonic Prime Ultra 550 Platinum Power
Supply
Overview
PRIME Ultra 550 Platinum
The Seasonic PRIME 80 PLUS® Platinum certified power supply is rated to
achieve 92 % efficiency at 50 % system load. This high efficiency ensures that
there is less heat wasted during operation, which in turn not only reduces the
strain on the system components but it also lowers the costs of electricity for
users. An ultra-quiet, 135 mm Fluid Dynamic Bearing Fan (regulated by Seasonic’s
proprietary Premium Hybrid Fan Control) delivers excellent airflow with
exceptionally low noise levels. This unit is an ideal companion to an office
computer or an environment where noise levels need to be at the minimum.
Features
80 PLUS®Platinum
The higher the level of efficiency of the power supply, the less power gets
wasted in the form of excess heat . The 80 PLUS® Platinum certification
guarantees greater than 90 %, 92 % and 89 % efficiency at 20 %, 50 % and 100 %
operating loads, respectively. The Seasonic Platinum Series represents the
highest level of technology and efficiency achievement of Sea Sonic during its
40 years of commitment to engineering excellence.
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. The following illustration depicts the main characteristics of the FDB
fans:
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.
Power Supply Sound
The Seasonic PRIME Series is designed with very favorable level of acoustics
and it uses carefully selected components and innovative circuit design to
minimize sound output. Beyond our rigorous internal tests, the power supply also
went through external testing with the most popular graphics cards to ensure
that the sound at all loads would be kept at the lowest possible level. The
chart compares the sound level of the Seasonic PRIME power supply to other
ambient sounds.
Micro Tolerance Load Regulation
Seasonic’s latest design keeps the output voltage within a very tight range,
achieving under 0.5 % (1 % for 1000 W and above) load regulation. This
impressive electrical performance and stability makes this power supply an ideal
choice for high-performance systems.
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.
Multi-GPU Setup
Our power supplies are equipped with 6-pin and 8-pin PCI-E connectors to
support all GPU platforms.
Gold Plated Connectors
Gold plating critical connector pins (motherboard, CPU and PCIe cables)
extends the lifetime of the connectors and greatly increases the efficiency of
current transmission.
12 Years Warranty
Our commitment to superior Seasonic quality.
