CORSAIR RM850x Fully Modular Low-Noise ATX Power Supply vs CORSAIR RM1000x SHIFT

Overview of the Power Supplies

The CORSAIR RM850x and CORSAIR RM1000x SHIFT are both high-quality power supplies designed for PC enthusiasts, but they cater to slightly different needs. The RM850x is priced at £124.40, while the RM1000x SHIFT comes in at £164.99. This price difference of £40.59 reflects the additional features and capabilities of the RM1000x SHIFT, making it essential to understand what each model offers.

Efficiency and Certification

When it comes to efficiency, the CORSAIR RM850x boasts a Cybenetics Gold certification, achieving up to 91% efficiency. This is crucial for users looking to reduce power consumption and maintain cooler temperatures. On the other hand, the RM1000x SHIFT, while not explicitly rated in the data, typically targets a high-efficiency standard that would be expected of a premium PSU. Users can expect both units to perform well, but the RM850x has a clear metric for its efficiency.

Modular Design

The fully modular design of the CORSAIR RM850x allows users to connect only the cables they need, reducing clutter and improving airflow within the case. In contrast, the RM1000x SHIFT takes modularity a step further with its innovative side-mounted connections, which simplify cable management. This additional convenience can be particularly advantageous for users who frequently upgrade or change their components. Both units excel in modularity, but the RM1000x SHIFT provides a unique angle on ease of access.

Compatibility with Modern Hardware

Both the CORSAIR RM850x and RM1000x SHIFT are equipped with native 12V-2x6 GPU cables, ensuring compatibility with the latest graphics cards, including those from NVIDIA's 50 Series. This ensures that users can build high-performance systems without needing adapters. The RM850x also supports the latest ATX 3.1 power standard, which is vital for future-proofing, especially as new hardware comes to market. While both supplies cater to modern needs, the RM850x’s ATX compliance is a noteworthy feature for those looking to stay ahead.

Noise Levels and Cooling

Noise levels can significantly impact the overall user experience, especially in high-performance builds. The CORSAIR RM850x is designed with low-noise operation in mind, making it an excellent choice for quiet systems. Meanwhile, the RM1000x SHIFT features a 140mm fluid dynamic bearing fan that is engineered for high performance and low noise, ensuring a quiet operation even under load. Both units aim for quiet performance, but the RM1000x SHIFT's specific fan design may provide superior cooling efficiency.

Aesthetic Appeal

The aesthetic design of a power supply can influence the overall look of a build. The CORSAIR RM850x comes with sleek embossed cables that are ultra-flexible, making installation and routing a breeze. The RM1000x SHIFT, however, elevates aesthetics with its debossed PVC cable kit, which not only looks clean but also enhances cable management with included low-profile combs. Both models cater to aesthetic considerations, but the RM1000x SHIFT may appeal more to users who prioritise visual coherence in their builds.

Price Consideration

The price difference between the two models cannot be overlooked. The CORSAIR RM850x is available for £124.40, while the RM1000x SHIFT is priced at £164.99. This £40.59 difference reflects the RM1000x SHIFT's additional features, such as improved cable management and potentially better cooling capabilities. For users on a budget, the RM850x offers excellent value without sacrificing essential features, while those willing to invest more may find the enhancements of the RM1000x SHIFT worth the extra cost.

Which should you buy?

Choosing between the CORSAIR RM850x and the RM1000x SHIFT largely depends on your specific needs and budget. If you're looking for a reliable, efficient power supply that meets modern standards without breaking the bank, the RM850x is an outstanding choice at £124.40. However, if you desire advanced features like easier cable management and superior cooling with a price tag of £164.99, the RM1000x SHIFT is likely the better option. Ultimately, both power supplies deliver quality, but your choice should align with your preferences for performance, aesthetics, and budget.
