Review CORSAIR Rmx Shift Series 850 Watt Atx 3.1 Pcie 5.1 Cybenetics Gol
Introducing the Corsair RM850x (CP-9020299) 850W 80 Gold Certified Fully Modular ATX Power Supply, a high-performance and efficient solution for powering your modern PC systems. This power supply unit (PSU) is part of Corsair's renowned RMx series, which combines a sleek design, quiet operation, and reliable power delivery.
The RM850x delivers an impressive 850 watts of power at an 80 Gold efficiency level. This means that it converts up to 90% of the electrical energy it consumes into usable power for your components, minimizing energy waste and reducing your carbon footprint. The Gold certification also ensures stable voltage levels under various loads and temperatures, ensuring optimal system performance.
This PSU is fully modular, allowing you to connect only the cables that you need, simplifying cable management within your PC case. Each cable is independently sleeved, giving your build a clean and organized appearance. The RM850x comes with a rich set of connectors, including 1 x 24-pin ATX, 1 x 4 4-pin EPS12V, 6 x 6 2-pin Peripheral, and 12 x SATA and 4 x 6 2-pin Molex connectors.
Corsair's 0 RPM fan technology is integrated into the RM850x, ensuring quiet operation under typical loads. The fan only spins up when necessary, further reducing noise levels and providing a more enjoyable PC experience. The fan's hydraulic dynamic bearings also ensure long-lasting performance and reduce the risk of failure.
The Cybenetics Gol certification further validates the RM850x's high-quality design and performance. This certification is based on strict testing criteria, ensuring that the PSU can handle extreme loads and temperature conditions without compromising its stability.
The RM850x's compact size, measuring 150mm in depth, makes it a great choice for most ATX cases. It also supports the latest PCIe 5.1 standard, providing ample power for high-end graphics cards and other power-hungry components.
In summary, the Corsair RM850x (CP-9020299) is a top-tier, fully modular, 850-watt power supply that offers exceptional efficiency, quiet operation, and reliable power delivery. Its Gold certification, 0 RPM fan technology, and Cybenetics Gol validation make it an excellent choice for powering modern PC systems, whether for gaming, content creation, or professional use.
The Corsair RM850x (CP-9020299-NA) is a high-performance, 850-watt, fully modular ATX power supply unit (PSU) with 80 Gold certification. Here are some pros and cons that might help you decide whether or not to purchase this PSU:
Pros:1. High efficiency: The 80 Gold certification ensures that the PSU converts at least 90% of the input power into output power under typical loads.
2. Fully modular design: This allows users to connect only the cables they need, reducing clutter and improving airflow within the case.
3. Quiet operation: The RM850x uses a Zero RPM fan mode, which means the fan doesn't spin unless the PSU is under heavy load or the temperature reaches a certain threshold.
4. High-quality components: Corsair uses Japanese capacitors and a low-ripple design to minimize voltage fluctuations and ensure reliability.
5. Compatibility with modern components: The PSU supports PCIe 5.1 and has a dedicated 12VHPWR connector for high-end graphics cards.
Cons:1. Price: The RM850x is more expensive than some other 850-watt power supplies from competing brands.
2. Size and weight: This PSU is larger and heavier than some other options in its class, which could be a concern for those with limited space in their cases.
3. No DC-DC converter: Unlike some high-end PSUs, the RM850x does not have a DC-DC converter for the 12V rails. This means that it may not be able to deliver the full 850 watts on the 12V rails simultaneously.
In conclusion, the Corsair RM850x (CP-9020299-NA) is a high-quality, efficient, and quiet power supply unit that offers excellent compatibility with modern components. However, its price, size, and weight may be drawbacks for some users. If you're looking for a reliable and efficient power supply for a high-performance system and don't mind the higher cost, the RM850x could be a good choice.
Recommendation:If you're looking for a high-performance, fully modular ATX power supply with a quiet operation and excellent compatibility with modern components, the Corsair RM850x (CP-9020299-NA) is a solid option. However, if you're on a tighter budget or have space constraints, you may want to consider other options such as the EVGA 850W QUQO or the Seasonic Focus Gold 850W.
