Price Comparison
The ARESGAME AGV Series 650W Power Supply is priced at $44.99, while the NZXT C850 Gold Core comes in at $99.99. This makes the ARESGAME about 55% cheaper than the NZXT. For budget-conscious consumers, the lower price point of the ARESGAME may be appealing, especially for those who need a reliable power supply without breaking the bank. However, the higher price of the NZXT reflects its premium features and certifications, which may justify the investment for those looking for advanced performance and efficiency.
Efficiency Ratings
Efficiency is a critical factor in power supplies, and here the ARESGAME holds an 80 Plus Bronze certification, achieving 85% efficiency or higher under typical loads. In contrast, the NZXT boasts an 80 Plus Gold rating, which signifies even better energy efficiency, and is backed by a Cybenetics Platinum certification. This means that the NZXT not only delivers stable performance but also reduces heat and power draw more effectively than the ARESGAME. For users focused on long-term energy savings and reduced electricity bills, the NZXT’s superior efficiency could present a compelling reason to choose it.
Modular Design
The ARESGAME AGV Series is a non-modular power supply, meaning all cables are permanently attached. This can lead to a cluttered build if not managed properly. On the other hand, the NZXT C850 Gold Core is fully modular, allowing users to connect only the cables they need. This modularity provides a cleaner look and better airflow within the PC case. For those who prioritize aesthetics and ease of installation, the modular design of the NZXT could be a significant advantage.
Cooling Performance
Cooling performance is crucial for maintaining optimal operation. The ARESGAME features a silent 120mm fan that provides excellent cooling performance, while the NZXT utilizes a 135mm fluid dynamic bearing fan with a Zero RPM mode. This means the NZXT fan operates silently during light workloads, which is particularly beneficial for users who want a quiet system. The superior cooling capabilities of the NZXT, combined with its noise ratings, make it a better choice for those seeking a quiet yet powerful power supply.
Compatibility with Modern GPUs
When it comes to compatibility, the NZXT C850 is designed to support next-gen GPUs with a dual-color 12V-2x6 connector, making it ideal for modern NVIDIA graphics cards. It also accommodates up to three 8-pin PCIe cables for additional flexibility. In contrast, while the ARESGAME supports high-end VGA cards with a PCI-E 6+2 pin connector, it lacks the advanced features and compatibility that the NZXT offers for the latest graphics technologies. Gamers looking to future-proof their systems may find the NZXT to be the superior option.
Warranty and Reliability
The ARESGAME comes with a 5-year warranty, which is respectable for a power supply in its price range. However, the NZXT ups the ante with a 7-year warranty, reflecting its confidence in the product’s longevity and reliability. This extended warranty can provide peace of mind for users who are investing in a more expensive unit. The premium components used in the NZXT are also rated for 105°C, ensuring stable performance under demanding conditions, making it a potentially more reliable choice over time.
User Experience
Both power supplies aim to enhance user experience but do so in different ways. The ARESGAME provides a straightforward installation process with long cable lengths to support high-end cases and includes cable ties for organization. The NZXT, however, focuses on a clean and compact design with embossed cables, allowing for easier routing and less clutter. Users who value organization and aesthetics in their builds may prefer the user-friendly design of the NZXT, while those looking for simplicity might appreciate the ARESGAME.
Which should you buy?
Choosing between the ARESGAME AGV Series 650W Power Supply and the NZXT C850 Gold Core largely depends on your specific needs and budget. The ARESGAME is an excellent choice for those seeking a cost-effective solution with solid performance for basic gaming setups. However, if you prioritize efficiency, modularity, and future compatibility with advanced GPUs, the NZXT offers superior features that may justify its higher price. Ultimately, your decision should weigh the importance of these factors against your budget and performance requirements.
