NZXT C850 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 850 Wa vs CORSAIR RM1200x SHIFT Fully Modular ATX Power Supply - 80 PLUS Gold - ATX 3.1 -

Price Comparison

When it comes to pricing, the NZXT C850 Gold is significantly more affordable than the CORSAIR RM1200x SHIFT. The NZXT C850 Gold is priced at £84.90, while the CORSAIR RM1200x SHIFT comes with a price tag of £174.98. This price difference of £90.08 may be a crucial factor for budget-conscious gamers or PC builders. Despite its lower cost, the NZXT C850 Gold offers essential features that cater to high-performance gaming, making it an attractive option for those looking to save while still getting quality power supply.

Power Efficiency

Both power supplies are compliant with the ATX 3.1 standard, ensuring high efficiency and stability for demanding PC components. The NZXT C850 Gold is designed to provide up to 850 watts, which is adequate for most gaming setups, while the CORSAIR RM1200x SHIFT offers a more robust output of 1200 watts. The 80 PLUS Gold certification for both products indicates that they maintain high efficiency levels, but the CORSAIR model's higher wattage capacity allows for more extensive systems or future upgrades. This makes the CORSAIR RM1200x SHIFT a better choice for users planning to run multiple high-performance components or considering future expansions.

Noise Levels

Noise output is a critical aspect for gamers and PC users who desire a quieter environment. The NZXT C850 Gold features a 135mm fluid dynamic bearing fan with a Zero Fan Mode, which operates silently under 50% load. This is particularly beneficial for those who prefer a quiet gaming experience. In contrast, the CORSAIR RM1200x SHIFT utilises a 140mm fluid dynamic bearing fan, which is engineered for low noise while maintaining high performance. Although both power supplies are designed with noise reduction in mind, the NZXT C850 Gold specifically targets silent operation at lower loads, potentially making it the better option for quiet builds.

Build Quality

The build quality of both power supplies is impressive, but they differ in their internal components. The NZXT C850 Gold boasts 100% premium Japanese capacitors, which enhance hold-up time and minimise ripple noise, ensuring a stable power delivery. The CORSAIR RM1200x SHIFT, on the other hand, also features 100% 105°C-rated Japanese electrolytic capacitors, which promise unwavering power delivery and long-term reliability. While both products utilise high-quality components, the CORSAIR model's focus on reliability and performance under high loads may appeal more to users who push their systems to the limit.

Cable Management

In terms of cable management, the CORSAIR RM1200x SHIFT offers innovative side-mounted modular connections, making it easier to access and manage cables. This design promotes cleaner builds and simplifies the installation process, which can be a significant advantage for users who value aesthetics and organisation in their setups. The NZXT C850 Gold is fully modular as well but does not highlight any specific cable management features in its design. Thus, for users who prioritise ease of installation and cable management, the CORSAIR model may be the more appealing choice.

Compatibility

Both power supplies are ATX 3.1 compliant, ensuring compatibility with modern components. The NZXT C850 Gold is specifically noted to support NVIDIA GeForce RTX 50 Series graphics cards with a durable 12V-2x6 connector, allowing for a stable power supply to these high-performance GPUs. Meanwhile, the CORSAIR RM1200x SHIFT is certified for Intel ATX 3.1 and supports the PCIe Gen 5.1 platform. This makes the CORSAIR model particularly future-proof for users investing in the latest technology. For those looking to build systems with cutting-edge components, the CORSAIR RM1200x SHIFT may offer a slight edge in compatibility.

User Experience

User experience can often hinge on the ease of installation and overall performance during operation. The NZXT C850 Gold's emphasis on low noise and stable power delivery creates a positive experience for gamers who desire reliability without disruptive sounds. The CORSAIR RM1200x SHIFT enhances user experience through its thoughtful design, allowing for simplified cable management and easier access to connections. While both products are designed with user satisfaction in mind, the CORSAIR model's focus on modularity and performance could provide a more seamless experience for high-end builds.

Which should you buy?

In conclusion, the choice between the NZXT C850 Gold and the CORSAIR RM1200x SHIFT largely depends on your specific needs and budget. If you are seeking a cost-effective solution with excellent noise control and sufficient power for most gaming setups, the NZXT C850 Gold at £84.90 is a commendable option. However, if you require a higher wattage capacity for a more demanding system, or if cable management and future-proofing are your priorities, the CORSAIR RM1200x SHIFT at £174.98 is worth the investment. Ultimately, both power supplies have their strengths, making either a solid choice depending on your individual requirements.
