100% modular power supply 750W ATX/EPS 12V - 80PLUS Gold

Overview

Seasonic PRIME GX : High quality 80+ Gold third generation power supply

The Seasonic PRIME GX features 80+ Gold certification, a 100% modular design and allows fanless operation below 40% load. It features a quiet 135mm fan and rich connectivity to power the most powerful components with reliable and stable voltage.

Featuring the latest technological advances, the PRIME GX maintains the output voltage within a very tight range, achieving load regulation of less than 0.5% (MTLR). This impressive power performance and stability make this power supply an ideal choice for high performance systems.

FDB Fan

The 135mm high performance fan in this power supply is designed to take advantage of the impact absorption effects of oil. It is extremely reliable and generates much less operating noise and heat than ball-bearing fans. Lubrication of the bearing surface reduces friction and vibration, thus reducing overall energy consumption. Due to the effortless and quieter rotations and the robust construction, this proven fan technology also increases the life of the fan.

Hybrid cooling

This Seasonic PRIME power supply features the Premium Hybrid Fan Control system, which minimises the noise generated by the fan. Below 40% load, the unit is in 0dB (fanless) mode and then the fan turns on in proportion to the load of the configuration.

Internal cable-free design

Seasonic engineers have implemented a new internal design, where instead of cables, the back panel and the PCB (Printed Circuit Board) are connected by a copper plate. This solution not only reduces the risks during assembly, but also improves the quality and reliability of the power output.

    Very good product

    Obviously it's not cheap... but when you see the box and especially its contents, you understand! Very quiet power supply with a very complete set of connectors, including fasteners to have something very clean. I'm very happy with this product.
    The package is very well packaged and the delivery is fast.
