Review CORSAIR White 850 Watt Gold Certified Power Supply Unit Psu Only

Introducing the Corsair RM850x, an 850-watt 80 Gold certified power supply unit (PSU) engineered for high performance and exceptional efficiency. This fully modular power supply allows you to use only the cables you need, reducing clutter in your case and simplifying installation.

The RM850x is built with a single 12V rail design, delivering a stable and consistent power output to all components. It employs a quiet 140mm hydrodynamic fan for efficient cooling and almost inaudible operation, even under heavy load. This fan utilizes a magnetic bearing design that minimizes friction and wear, ensuring long-lasting performance and reliability.

Corsair's proprietary Zero RPM fan technology is another standout feature. When the PSU is operating below a specific load threshold, the fan remains off, completely eliminating fan noise in these situations. This technology not only enhances the overall silence of your system but also contributes to the PSU's impressive efficiency.

The RM850x is constructed with 105 C 105 C Japanese capacitors and a multitude of protection features, including over-voltage protection, under-voltage protection, over-current protection, over-power protection, and short-circuit protection. These safeguards ensure that your components are always protected from potential power-related issues.

This PSU also includes a universal AC input and a 20 4 4 2 PCIe connector configuration, ensuring compatibility with a wide range of systems and providing ample connectivity for high-end graphics cards and additional storage devices.

In summary, the Corsair RM850x is a high-performance, efficient, and quiet power supply unit that is perfect for building or upgrading a modern system. Its fully modular design, single 12V rail, Zero RPM fan technology, and robust protection features make it a reliable and intelligent choice for any enthusiast or professional user.

The Corsair RM850x (CP-9020156) is a high-performance 850-watt 80 Gold certified power supply unit (PSU). Here are some pros and cons that may help you decide if this PSU is the right choice for your build.

1. High efficiency: The 80 Gold certification ensures that the PSU converts at least 87% of the input power into output power under typical loads.

2. Quiet operation: The RM850x utilizes a fully modular design, which allows users to only connect the cables they need, reducing fan noise and heat output.

3. High-quality components: Corsair uses Japanese capacitors and a single 12V rail to ensure stable and reliable power output.

4. Compact size: Despite delivering 850 watts, the RM850x has a relatively small form factor, making it a good choice for compact builds.

5. Active PFC: The PSU has an active power factor correction (PFC) circuit, which ensures that it complies with the power requirements of modern systems and reduces power loss.

1. Price: The RM850x is more expensive than some other 850-watt PSUs on the market.

2. Limited connectors: The PSU only comes with eight SATA connectors, which may not be enough for some users with multiple hard drives or SSDs.

3. No DC output: The RM850x does not have a DC output for peripherals, which may be a drawback for some users who prefer using DC power for their accessories.

In conclusion, the Corsair RM850x (CP-9020156) is a high-quality, reliable, and efficient power supply unit that is well-suited for high-performance systems. Its fully modular design, quiet operation, and high-quality components make it a great choice for users who demand the best from their components. However, its higher price point and limited number of connectors may be a drawback for some users. Ultimately, if you're looking for a high-performance, quiet, and reliable power supply unit, the Corsair RM850x is a great option to consider.
