NZXT C850 SFX Gold - 850W SFX ATX 3.1 Power Supply - 80 Plus Gold - Cybenetics P vs GameMax 750W Rampage Power Supply

Price Comparison

The NZXT C850 SFX Gold is priced at £129.98, whereas the GameMax 750W Rampage is significantly cheaper at £45.80. This represents a difference of £84.18, making the GameMax a more budget-friendly option for users looking to save on their power supply purchase. While the lower price point of the GameMax may attract first-time builders or those on a tight budget, it raises questions about performance and efficiency compared to the more premium NZXT offering.

Efficiency Ratings

In terms of efficiency, the NZXT C850 SFX Gold boasts an 80 PLUS Gold rating, indicating it achieves at least 87% efficiency at a 20% load and up to 90% at a 50% load. On the other hand, the GameMax 750W Rampage carries an 80 PLUS Bronze certification, which means it achieves an efficiency of up to 88% at a 50% load. This signifies that while both power supplies are efficient, the NZXT model offers slightly better performance in terms of energy savings and heat output, making it a more suitable choice for users looking to optimise their systems for lower power consumption.

Build Quality and Reliability

The NZXT C850 SFX Gold is designed for compact builds and delivers full power capabilities in a size optimised for small form factor cases. It features a Cybenetics Platinum efficiency rating, which often correlates with higher reliability and performance. In contrast, the GameMax 750W Rampage, while built with quality components including a Japanese TK main capacitor for reliability, is described as suitable for basic systems and gaming rigs. The added assurance of premium components in the NZXT power supply may appeal to those prioritising longevity and stability in their builds.

Cooling Solutions

When it comes to cooling, the NZXT C850 SFX Gold utilises a 92 mm fluid dynamic bearing (FDB) fan that provides efficient cooling and includes a Zero RPM mode for silent operation. This feature is particularly valuable for users who seek a quieter system. The GameMax 750W Rampage, however, employs a larger 14 cm cooling fan that ensures silent operation while effectively managing heat. Although both options aim for quiet performance, the NZXT’s advanced cooling technology may provide an edge in maintaining optimal temperatures over extended periods.

Power Delivery

The NZXT C850 SFX Gold supports modern graphics cards with its ATX 3.1 certification and includes a 600W 12V-2x6 connector for reliable GPU power delivery. This makes it an excellent choice for gamers and professionals who require stable and robust power for high-performance components. Conversely, the GameMax 750W Rampage features a single 12V rail which offers high compatibility and extreme current output. While both power supplies deliver adequate power for gaming and demanding applications, the NZXT’s certification offers an extra layer of assurance for users with high-end setups.

Cable Management

The GameMax 750W Rampage features a semi-modular design, which simplifies cable management and allows for a cleaner build. This is particularly beneficial for users who value aesthetics and airflow within their PC cases. In comparison, the NZXT C850 SFX Gold does not specify a modular design, which may lead to more cluttered cable arrangements. For builders who prioritise a clean and organised setup, the semi-modular aspect of the GameMax could be a decisive factor.

Target Audience

The NZXT C850 SFX Gold is ideal for compact builds and users who demand high performance and reliability, making it a suitable choice for enthusiasts and professional gamers. Its price reflects its premium features and efficiency, catering to those who are willing to invest in quality. On the other hand, the GameMax 750W Rampage targets budget-conscious users, first-time builders, and those looking for a reliable power supply without the premium price tag. Its semi-modular design and decent performance make it an attractive option for basic systems and gaming rigs.

Which should you buy?

In summary, the choice between the NZXT C850 SFX Gold and the GameMax 750W Rampage largely depends on your specific needs and budget. If you are looking for a high-efficiency power supply with superior build quality and advanced cooling features, the NZXT C850 SFX Gold is worth the investment at £129.98. However, if you are on a budget and need a reliable power supply for basic or gaming systems without compromising too much on performance, the GameMax 750W Rampage at £45.80 presents an excellent value. Ultimately, both power supplies cater to different segments of the market, ensuring that there are options available for a variety of users.
