NZXT C850 Gold ATX 3.1 - Fully Modular Low-Noise PC Gaming Power Supply - 850 Wa vs GameMax 750W Rampage Power Supply

Price Comparison

The NZXT C850 Gold is priced at £84.90, while the GameMax 750W Rampage is significantly cheaper at £45.80. This represents a difference of £39.10, making the GameMax a more budget-friendly option for those looking to save on their power supply purchase. While the NZXT offers higher wattage and advanced features, the disparity in price might appeal to gamers or PC builders who are looking to manage costs without compromising too heavily on quality.

Power Output

The NZXT C850 Gold boasts an impressive power output of 850 watts, making it suitable for high-performance gaming rigs and demanding components. In comparison, the GameMax 750W Rampage offers a lower output of 750 watts. This 100-watt difference could matter for users with particularly power-hungry setups, especially if they plan to run high-end graphics cards or multiple components. The NZXT's higher capacity provides extra headroom for future upgrades, while the GameMax may suffice for mid-range builds.

Efficiency Ratings

The NZXT C850 Gold is designed with compliance to the ATX 3.1 standard, ensuring stability and efficiency under heavy loads. However, the GameMax 750W Rampage holds an 80 Plus Bronze certification, achieving up to 88% efficiency at 50% load. While both power supplies focus on delivering efficient performance, the NZXT's higher wattage and modern compliance may offer better long-term reliability for heavier usage scenarios, although the GameMax provides adequate efficiency for its price point.

Noise Levels

The NZXT C850 Gold features a 135mm fluid dynamic bearing fan with a Zero Fan Mode, ensuring that it operates silently when under 50% load. This could be particularly appealing for gamers who prioritise a quiet gaming environment. In contrast, the GameMax 750W Rampage is equipped with a 14cm cooling fan that also promises effective cooling while maintaining silence. However, the specific mention of Zero Fan Mode in the NZXT may give it an edge for users seeking near-silent operation during lighter workloads.

Build Quality and Components

The NZXT C850 Gold prides itself on high-quality construction, using 100% premium Japanese capacitors, which enhance hold-up time and minimise ripple noise. This suggests a robustness suited for long-term use and reliability under heavy loads. Meanwhile, the GameMax 750W Rampage also utilises a Japanese TK main capacitor, indicating a focus on quality assurance and lifespan. While both units aim for reliability, the premium components in the NZXT may offer a slight advantage in terms of performance stability over time.

Cable Management

The GameMax 750W Rampage incorporates a semi-modular cable management design, which facilitates a cleaner and more efficient build process. This is particularly beneficial for users who value neatness in their PC case. The NZXT C850 Gold, being fully modular, allows for even greater flexibility in cable management, enabling builders to use only the cables they require. This aspect can significantly improve airflow within the case and enhance overall aesthetics, making the NZXT a better choice for those who seek a meticulous build.

Compatibility

The NZXT C850 Gold is specifically noted for its compatibility with the NVIDIA GeForce RTX 50 Series graphics cards, delivering up to 600 watts through its durable 12V-2x6 connector. This makes it an excellent choice for users planning to invest in the latest high-performance graphics technology. On the other hand, the GameMax 750W Rampage offers a single 12V rail for compatibility with high-end components, making it suitable for various builds. However, the targeted design of the NZXT for cutting-edge graphics cards may appeal more to gamers anticipating future upgrades.

Which should you buy?

When deciding between the NZXT C850 Gold and the GameMax 750W Rampage, it ultimately comes down to individual needs and budget. The NZXT C850 Gold offers higher wattage, fully modular cable management, and premium components, making it ideal for serious gamers and high-performance builds at £84.90. Conversely, the GameMax 750W Rampage stands out as a more economical choice at £45.80, providing solid performance for mid-range systems with efficient cooling and adequate reliability. If budget constraints are significant, the GameMax is a commendable choice, but for those seeking long-term performance and the best features, the NZXT is worth the investment.
