Overview

When comparing the NZXT C850 Gold Core and the Seasonic Prime TX-1600 Noctua Edition, we see a stark contrast in pricing and specifications. The NZXT C850 is priced at £89.99, making it an affordable option for many users, while the Seasonic Prime TX-1600 commands a premium price of £429.00. This comparison will explore their features, performance, and overall value to help you decide which power supply suits your needs.

Efficiency Ratings

The NZXT C850 Gold Core boasts an 80 PLUS Gold rating, which indicates efficient energy use and reduced power draw under demanding loads. In contrast, the Seasonic Prime TX-1600 Noctua Edition elevates this efficiency with an 80 PLUS Titanium certification, achieving a remarkable 94% efficiency at 50% load. This means that while the NZXT is efficient, the Seasonic provides an even greater level of energy savings. For users concerned about their electricity bills, the Seasonic may justify its higher cost through long-term savings.

Noise Levels

When it comes to noise output, the NZXT C850 operates with a noise rating of A++ in Cybenetics certification, achieving less than 15 dBA during light workloads. This ensures a whisper-quiet operation suitable for gaming and work environments alike. On the other hand, the Seasonic Prime TX-1600 Noctua Edition features a renowned Noctua NF-A12x25 fan and is certified with Cybenetics Lambda A++ as well, but it is designed to be even quieter, operating at approximately 8-10 dB(A) lower than the regular model. This makes the Seasonic ideal for users who desire near-silent performance.

Compatibility with Modern GPUs

The NZXT C850 Gold Core is designed with future-proofing in mind, featuring ATX 3.1 certification and PCIe 5.1 readiness. It supports modern NVIDIA graphics cards with a dedicated dual-colour 12V-2x6 connector. The Seasonic Prime TX-1600 also meets ATX 3.1 and PCIe 5.1 standards, ensuring compatibility with high-end GPUs like the NVIDIA GeForce RTX 4090 series. Both power supplies are well-equipped to handle the latest graphics technology, but the Seasonic’s slightly higher wattage capacity may provide additional headroom for extreme builds.

Build Quality and Design

The NZXT C850 Gold Core features a standard design tailored for performance and efficiency, suitable for most builds. In contrast, the Seasonic Prime TX-1600 Noctua Edition is fully modular and features Noctua-themed cabling, which enhances the aesthetics and functionality of your build by reducing cable clutter. While both power supplies are well-built, the custom design of the Seasonic offers a more premium feel and the flexibility of a fully modular setup.

Operational Features

The NZXT C850 includes a 135 mm fluid dynamic bearing fan that operates quietly, with a Zero RPM mode during light loads to maintain silence. This feature is beneficial for users who prefer a quieter operation during non-intensive tasks. The Seasonic Prime TX-1600 takes this a step further with semi-passive operation, where the fan remains off until the load reaches 50%. This ensures that the power supply can operate virtually noiselessly during low workloads, making it an excellent choice for high-performance workstations that require silence.

Price Consideration

The NZXT C850 Gold Core is priced at a competitive £89.99, making it an attractive choice for budget-conscious consumers looking for reliable performance. In stark contrast, the Seasonic Prime TX-1600 Noctua Edition's price of £429.00 places it in the premium market segment. This substantial price difference may lead some users to question whether the additional features and performance of the Seasonic justify the cost, particularly for those with less demanding power needs.

Which should you buy?

Ultimately, choosing between the NZXT C850 Gold Core and the Seasonic Prime TX-1600 Noctua Edition comes down to your specific requirements and budget. If you are seeking a cost-effective, efficient power supply with good performance, the NZXT C850 at £89.99 presents a compelling option. However, if you require top-tier efficiency, ultra-quiet operation, and the ability to power high-performance components, the Seasonic Prime TX-1600 at £429.00 may be worth the investment. Consider your computing needs, desired noise levels, and budget constraints when making your final decision.
