NZXT C850 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 850 Wa vs CORSAIR RM1000e

Overview

In the realm of power supplies, both the NZXT C850 Gold and CORSAIR RM1000e stand out for their efficiency and build quality. The NZXT C850 Gold is priced at £84.90, while the CORSAIR RM1000e comes in at a higher £149.88. This price difference reflects variances in features and capabilities that are crucial for discerning gamers and PC builders.

Power Output

The NZXT C850 Gold offers a robust 850 watts of power, making it suitable for high-performance gaming setups that might require significant energy, especially with the latest GPUs. In contrast, the CORSAIR RM1000e provides 1000 watts, giving it an edge for more demanding systems or multi-GPU configurations. The choice between these two will largely depend on your specific power requirements, with the NZXT supporting up to 600 watts for NVIDIA GeForce RTX 50 Series graphics cards, which is quite impressive for its price range.

Efficiency and Standards

Both power supplies are compliant with the ATX 3.1 standard, ensuring they meet modern efficiency and performance benchmarks. However, the CORSAIR RM1000e supports PCIe 5.1 and can handle 2x transient power excursions from the GPU, which is particularly beneficial for cutting-edge graphics cards. The NZXT C850 Gold, while efficient, does not specifically mention support for PCIe 5.1, potentially limiting its compatibility with the very latest components.

Noise Level

When it comes to noise production, the NZXT C850 Gold excels with its ultra-low noise 135mm fluid dynamic bearing fan that operates silently under 50% load. This feature makes it an excellent choice for gamers seeking a quiet environment. The CORSAIR RM1000e, equipped with a 120mm rifle bearing fan, also prioritises low noise levels but may not achieve the same silent operation as the NZXT under lighter loads. The fan curve of the CORSAIR is specially calculated to minimise noise, even under full load, but the NZXT’s approach may appeal more to those who value silence during low-demand scenarios.

Build Quality

The build quality of both power supplies is commendable, but they differ in their construction materials. The NZXT C850 Gold boasts 100% premium Japanese capacitors, which enhance its hold-up time and reduce ripple noise, ensuring stable power delivery. The CORSAIR RM1000e features 105°C-rated capacitors, which are also designed for reliable performance but may not match the premium designation of the components found in the NZXT. Thus, while both brands focus on quality, the materials used in the NZXT could provide slight advantages in longevity and efficiency over time.

Modular Design

Modularity is a significant feature for modern power supplies, and both the NZXT C850 Gold and CORSAIR RM1000e are fully modular. This means you can connect only the cables necessary for your build, reducing clutter and improving airflow within the case. However, the NZXT’s focus on simplicity and the ease of installation may appeal to novice builders, while the CORSAIR’s slightly more complex modularity is designed for those who may have more demanding cabling needs. This aspect might sway users depending on their familiarity with PC building.

Compatibility and Future-Proofing

The CORSAIR RM1000e's support for PCIe 5.1 and its ability to withstand transient power surges make it a more future-proof choice for those looking to invest in cutting-edge technology. The NZXT C850 Gold, while powerful, lacks specific mentions of such advanced support, which could limit its adaptability as new standards emerge. For users planning to upgrade their systems frequently or utilise the latest GPU technology, the CORSAIR may be the safer option in terms of long-term compatibility.

Price Consideration

At £84.90, the NZXT C850 Gold presents an attractive option for those on a budget who still require quality and efficiency. The CORSAIR RM1000e's higher price of £149.88 may be justified by its additional features and higher wattage, appealing to serious gamers and enthusiasts who need that extra power. Ultimately, the decision may boil down to what features are most important to the user and whether the additional cost of the CORSAIR aligns with their specific needs and future plans.

Which should you buy?

Choosing between the NZXT C850 Gold and the CORSAIR RM1000e hinges on your specific requirements and budget. If you seek an affordable, quiet power supply with solid performance for standard gaming setups, the NZXT C850 Gold is an outstanding choice. Conversely, if your needs include higher wattage, future-proofing, and the latest compatibility standards, the CORSAIR RM1000e may be worth the investment. Assessing your power demands and how you plan to utilise your system will ultimately guide your decision.
