NZXT C850 SFX Gold - 850W SFX ATX 3.1 Power Supply - 80 Plus Gold - Cybenetics P vs Be Quiet! Pure Power 13M ATX 3.1-850w - 80 Plus Gold

Overview of Product Offerings

The NZXT C850 SFX Gold and Be Quiet! Pure Power 13M ATX 3.1 both offer users high-quality power supplies at competitive prices of £129.98 and £108.79, respectively. While both models provide 850W of power, they differ significantly in design, efficiency ratings, and features aimed at enhancing the user experience.

Design and Form Factor

The NZXT C850 SFX Gold is designed specifically for compact builds, utilising the SFX form factor to maximise space efficiency in small form factor (SFF) cases. This tailored design allows the power supply to deliver full-power capabilities without occupying excessive space. In contrast, the Be Quiet! Pure Power 13M adopts a standard ATX form factor, which is suitable for larger cases but may not fit as seamlessly in compact builds. Therefore, if space is a critical factor in your setup, the NZXT C850 SFX Gold is the more suitable choice.

Power Delivery and Connectivity

When it comes to power delivery, the NZXT C850 SFX Gold boasts ATX 3.1 certification and includes a 600W 12V-2x6 connector, ensuring reliable and safe power for modern graphics cards. The Be Quiet! Pure Power 13M, while also providing 850W, lacks specific details about its connectivity options, making it less clear how it caters to high-performance components. This distinction suggests that the NZXT C850 SFX Gold may offer more robust support for advanced gaming and computing needs.

Efficiency Ratings

The NZXT C850 SFX Gold is rated 80 PLUS Gold and boasts a Cybenetics Platinum efficiency rating, indicating a premium level of energy efficiency and lower heat output. In comparison, the Be Quiet! Pure Power 13M also holds an 80 PLUS Gold rating but does not provide further efficiency details, which could mean it is less efficient than the NZXT model. The enhanced efficiency of the NZXT C850 SFX Gold could result in reduced energy costs and a cooler-running system, making it a potentially better investment in the long term.

Noise Levels and Cooling

One of the standout features of the NZXT C850 SFX Gold is its quiet operation, highlighted by a Cybenetics A- noise rating. It employs a 92 mm fluid dynamic bearing fan that includes a Zero RPM mode for silent operation during low loads. The Be Quiet! Pure Power 13M, as implied by its name, suggests a focus on quietness but lacks specific noise ratings or descriptions of its cooling mechanism. For users prioritising a silent computing experience, the NZXT C850 SFX Gold clearly presents a better option, as it is designed to minimise noise without sacrificing performance.

Component Protection and Reliability

The NZXT C850 SFX Gold features low ripple noise, tight voltage regulation, and a long hold-up time, all of which contribute to uninterrupted system performance and enhanced component protection. These features are essential for maintaining system stability and longevity, particularly for high-performance builds. In contrast, the Be Quiet! Pure Power 13M does not provide any detailed information regarding its component protection capabilities. This lack of information may lead to concerns about reliability, making the NZXT C850 SFX Gold a more reassuring choice for discerning users.

Price Comparison

With a current price of £129.98, the NZXT C850 SFX Gold is positioned as a premium option in the market, reflecting its advanced design and efficiency features. The Be Quiet! Pure Power 13M, priced at £108.79, presents a more budget-friendly alternative while still offering the essential 850W power. However, the additional features and superior performance of the NZXT model may justify the higher price for users seeking optimal performance and reliability. Ultimately, your choice may hinge on whether you value the premium features of the NZXT or prefer the cost-effective solution of the Be Quiet! model.

Which should you buy?

In conclusion, the NZXT C850 SFX Gold stands out as the superior choice for users seeking a compact, efficient, and quiet power supply with robust performance and protection features, despite its higher price of £129.98. On the other hand, the Be Quiet! Pure Power 13M offers a more affordable option at £108.79, but it lacks the detailed performance and reliability assurances found in the NZXT model. If you're building a high-performance system and prioritising efficiency and noise reduction, the NZXT C850 SFX Gold is the clear winner. However, for general usage and budget-conscious consumers, the Be Quiet! Pure Power 13M may still be a viable option.
