be quiet! Dark Power 14 1200W, ATX 3.1, 80 Plus® vs CORSAIR RM850x Fully Modular Low-Noise ATX Power

Overview of the Products

The be quiet! Dark Power 14 1200W is a high-end power supply designed for demanding systems, while the CORSAIR RM850x offers a more budget-friendly option with robust features. The Dark Power 14 is priced at $289.90, making it about 79% more expensive than the RM850x, which retails for $161.93. Both are compliant with ATX 3.1 standards and support PCIe 5.1, but they cater to different segments of the market based on price and performance needs.

Design and Build Quality

Both the be quiet! Dark Power 14 1200W and the CORSAIR RM850x feature fully modular designs, allowing users to connect only the cables necessary for their systems. The Dark Power 14, however, is engineered with enhanced cooling capabilities, including active and semi-passive cooling modes. This offers superior performance under load, which is critical for high-end systems. In contrast, the RM850x is designed for efficiency, featuring Cybenetics Gold certification with a rating of up to 91%. This translates to lower temperatures and noise, but it may not match the premium build quality of the Dark Power 14, which boasts a Titanium efficiency rating of up to 95.42%.

Efficiency and Performance

The efficiency of a power supply directly impacts its performance and operating costs. The be quiet! Dark Power 14 boasts an impressive 80 PLUS Titanium rating, indicating it is designed to deliver superior energy efficiency, especially at higher loads. This power supply ensures less power consumption and quieter operation, making it ideal for overclocked systems. On the other hand, the CORSAIR RM850x, with its Cybenetics Gold certification, offers reliable performance with a maximum efficiency of 91%. While both units provide excellent performance, the Dark Power 14 is the clear winner in terms of energy efficiency.

Cooling Solutions

Cooling is an essential factor in maintaining power supply performance, especially under heavy loads. The Dark Power 14 features a unique cooling solution with a Silent Wings fan that can operate in both active and semi-passive modes. This adaptability allows users to choose between quiet operation and consistent cooling, depending on their system's demands. The RM850x also focuses on low noise, employing a 140mm FDB fan for cooling. However, it lacks the dual cooling modes of the Dark Power 14, which provides more flexibility in managing heat.

Compatibility and Connectivity

Both power supplies feature native 12V-2x6 connectors, ensuring compatibility with the latest graphics cards without the need for adapters. The Dark Power 14 offers more extensive connectivity with four PCIe 6+2-pin connectors, accommodating a wider range of current and next-generation GPUs. This versatility makes it especially suitable for high-end gaming rigs or workstations. Conversely, the RM850x is also designed to support modern hardware but may have limitations in terms of connecting multiple high-power GPUs simultaneously compared to the Dark Power 14.

Warranty and Support

Warranty length is a crucial factor when investing in a power supply. The be quiet! Dark Power 14 comes with a standard warranty, but the exact duration is not specified in the provided data. The CORSAIR RM850x, however, is backed by an impressive ten-year warranty, providing buyers with peace of mind regarding long-term reliability. A longer warranty often indicates a manufacturer’s confidence in their product, making the RM850x a more appealing option for those concerned about potential failures over time.

Price Comparison

When it comes to pricing, the be quiet! Dark Power 14 is significantly more expensive at $289.90, while the CORSAIR RM850x is priced at $161.93. This price difference of about 79% can be a deciding factor for many consumers. While the Dark Power 14 offers advanced features and higher efficiency, those on a tighter budget or with less demanding systems may find the RM850x provides excellent value for its price, especially considering its features and the ten-year warranty.

Which should you buy?

Ultimately, your choice between the be quiet! Dark Power 14 1200W and the CORSAIR RM850x will depend on your specific needs and budget. If you are building a high-end system that requires superior efficiency, extensive connectivity, and advanced cooling solutions, the Dark Power 14 is worth the investment. However, if you are looking for a reliable, cost-effective power supply that still meets modern demands, the RM850x is an excellent option at a significantly lower price.
