Seasonic Prime Ultra GX-1000 1000W 80+ Gold ATX Fully-Modular Power Supply V2

Description

80 PLUS® Titanium Certified

The PRIME Titanium Series achieves the highest level of 80 PLUS® Titanium certification on the market with its 94 % efficiency at 50 % system load. (The feature only applies to PRIME Titanium Series.)

MTLR

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.

Extended Hold-up Time (30 ms)

Improved circuit design and high-quality components have greatly increased the hold-up time measured under 100 % load, from an industry standard of 16 ms to above 30 ms. This substantial improvement means that even under unstable input current conditions the power supply will continue to output stable and precise current to ensure smooth operations. (The feature only applies to PRIME Titanium Series.)

Super Low Ripple Noise (20 mV)

Seasonic’s continued commitment to excellent analog power supply design has suppressed ripple noise to fall well below the current industry average of 20 mV. (The feature only applies to PRIME Titanium Series.)

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.

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.

135 mm FDB Fan

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 FDB 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.
