Seasonic presents the PRIME SnowSilent power supply series featuring an all-white chassis, improved low-load efficiency and a very generous 12-year warranty on all its models. The Seasonic PRIME SnowSilent power supplies are offered in three unique models – the SnowSilent 550 Gold, SnowSilent 650 Platinum, and SnowSilent 750 Titanium.

SnowSilent 750 Titanium

This model offers the highest efficiency of 94% at 50% load with its 80 PLUS Titanium certification. The PRIME SnowSilent 750 Titanium is also the highest wattage model of the series.

SnowSilent 650 Platinum

The sweet spot in all three power supply models with its 80 PLUS Platinum certification offering 92% efficiency at 50% load.

SnowSilent 550 Gold

The PRIME SnowSilent 550 Gold offers the lowest wattage capacity with a modest 80 PLUS Gold certification offering 90% efficiency at 50% load.

Seasonic PRIME SnowSilent Features

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 make 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.

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.
