Users frequently appreciate the near silent operation thanks to the Smart Zero Fan feature, which keeps the system quiet during typical use. The perceived build quality, supported by high-grade components and a substantial 10-year warranty, instills strong confidence in its longevity and reliability. While the included cables can sometimes be stiff, the overall consensus celebrates this power supply for its strong performance and quiet efficiency, positioning it as a highly recommended choice.
Know before you buy
The 80 PLUS Gold rating indicates that this power supply is at least 90% efficient at typical loads. This means it wastes less energy as heat, which can lead to lower electricity consumption compared to less efficient units.
This unit is non-modular, meaning all cables are permanently attached to the power supply. While this requires a bit more cable management during your build, the included sleeved cables are designed to be flexible and easy to route.
Smart Zero Fan technology keeps the 120mm fan completely still when the power supply is under low loads, such as when you are browsing the web or working in documents. The fan only begins to spin once the unit reaches a certain temperature threshold, ensuring silent operation during light tasks.
850W is generally sufficient for most high-end single-GPU gaming builds. With a powerful single +12V rail and 6 PCIe connectors, it provides stable, consistent power for demanding components.
The unit includes a full suite of industrial-grade protections, including Over Voltage, Under Voltage, Over Power, Short Circuit, Over Current, and Over Temperature protection. These features are designed to shut down the unit automatically if an electrical fault is detected, helping to prevent damage to your other components.
Yes, the 140mm depth is quite compact for an 850W power supply. It is designed to fit standard ATX cases, offering plenty of clearance for cable management even in smaller mid-tower chassis.
