Seasonic Prime Ultra power supply unit 650 W 20+4 pin ATX ATX Black

Amazing Micro Tolerance Load Regulation technology ensures that the Seasonic PRIME 650 Titanium power supply will produce clean power at all times. Should there ever be a problem with the AC input power, this unit’s prolonged hold-up time will give ample buffer to prevent instabilities or, in case of a power shortage, it will allow the operating system save and store essential user data. Seasonic’s latest fan control design allows this unit to operate in fanless mode up to 45 % system load, to delight customers who are looking for a quiet power supply for their everyday usage.

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

Cybenetics ETA Efficiency Level A

The top-level Cybenetics rating badge testifies that the PRIME Titanium 650 operates between 91 % and 94 % efficiency at all times, at any load. The power supply achieves above 77 % efficiency on the 5 Vsb rail and it merely consumes less than 0.15 W when the system is idling.

Cybenetics LAMBDA Noise Level A++

The noise output of the power supply is as good as it can be; the PRIME Titanium 650 deserved the LAMBDA Noise Level A++ rating as its noise output stays below 20 dB(A) during operation.

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.

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.
