The Seasonic PRIME Platinum 850 watt power supply is a champion is stable and
reliable power delivery. It boasts a near-perfect voltage output which
represents Seasonics market leading engineering feat. This unit is ideal for
users who want o reduces noise levels in their work environment, as it has an
oversized, 135 mm Fluid Dynamic Bearing Fan that is controlled by Seasonics
proprietary Premium Hybrid Fan Control. An innovative Cable-free Connection
Design solution employs highly conductive copper plate to replace the
traditionally used cables for a cleaner design an to increase power
efficiency.
The higher the level of efficiency of the power supply, the less power gets
wasted in the form of excess heat . The 80 PLUSPlatinum
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
Seasonics 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
Seasonics 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
Seasonics 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.
