Price Comparison
The Apevia ATX-GX650W Galaxy is priced at $54.99, while the NZXT C850 Gold Core costs $99.99. This makes the Apevia about 45% cheaper than the NZXT. For budget-conscious gamers and PC builders, the lower price of the Apevia power supply may be attractive, particularly for those who do not require the higher wattage offered by the NZXT. However, the price gap reflects the differences in features and performance capabilities between the two products, which can be crucial for high-performance builds.
Power Output
In terms of power output, the NZXT C850 Gold Core offers 850W, significantly more than the 650W provided by the Apevia ATX-GX650W Galaxy. This difference in wattage is vital for users with high-performance setups, particularly those using the latest GPUs that demand more power. The increased capacity of the NZXT not only supports higher-end components but also provides more headroom for future upgrades. If you plan to build a powerful gaming rig or workstation, the extra wattage of the NZXT could be a deciding factor.
Efficiency Ratings
Both power supplies boast an 80 PLUS Gold certification, indicating high efficiency in their power delivery. However, the NZXT also holds a Cybenetics Platinum rating, which signifies even greater efficiency and performance stability under load. This distinction means that the NZXT C850 minimizes heat and power draw more effectively than the Apevia, particularly during demanding tasks. For users focused on energy conservation and optimal system performance, the NZXT's superior efficiency rating is a compelling reason to consider it despite the higher price.
Design and Modularity
The Apevia features a semi-modular design, allowing users to connect only the necessary cables, which aids in airflow and cable management. In contrast, the NZXT is fully modular, providing even greater flexibility in cable management and a cleaner build aesthetic. This full modularity allows users to use only the cables they need without excess clutter, making it easier to achieve an organized setup. For those who prioritize neatness and easy accessibility within their PC builds, the fully modular design of the NZXT may be the preferred choice.
Cooling Solutions
Cooling performance is another area where the two power supplies differ. The Apevia is equipped with a quiet 135mm thermally controlled fan that adjusts speed based on temperature, providing efficient cooling while minimizing noise. On the other hand, the NZXT features a fluid dynamic bearing fan with a Zero RPM mode, which operates silently during light workloads. This means the NZXT can offer near-silent operation under low stress, making it particularly appealing for users who are sensitive to noise. For gamers and professionals who want a quiet environment, the NZXT's cooling solution is a significant advantage.
Component Quality
When it comes to component quality, the NZXT C850 Gold Core is built with premium 105°C-rated capacitors, ensuring stable performance and longevity across various system loads. While the Apevia does not specify the quality of its capacitors, the mention of heavy-duty protections such as short-circuit and over-voltage safeguards suggests a solid build. However, the explicit use of high-quality components in the NZXT gives it an edge in durability and reliability, making it a better long-term investment for serious users.
Compatibility and Future-Proofing
The NZXT C850 is designed with modern GPUs in mind, featuring a dual-color 12V-2x6 connector for safe and efficient power delivery to the latest NVIDIA graphics cards. Its ATX 3.1 certification ensures compatibility with next-gen components, making it a future-proof choice for those looking to upgrade their systems. In contrast, while the Apevia supports various connectors and setups, it may not offer the same level of preparedness for emerging technology. Users planning to invest in cutting-edge hardware should consider the NZXT's advanced compatibility features as a critical factor in their decision.
Which should you buy?
Choosing between the Apevia ATX-GX650W Galaxy and the NZXT C850 Gold Core ultimately depends on your specific needs and budget. If you are looking for a budget-friendly option for a basic gaming or performance PC, the Apevia offers solid efficiency and essential features at a lower price point. However, for those who require higher wattage, advanced efficiency, and superior component quality, the NZXT is worth the investment despite its higher price tag. It provides the necessary support for modern hardware and offers greater long-term reliability, making it the better choice for serious gamers and PC builders.
