Price Comparison
The ARESGAME AGV Series 650W Power Supply is priced at $44.99, while the CORSAIR RM850e costs $94.99, making the ARESGAME model about 53% cheaper. This significant price difference may appeal to budget-conscious consumers looking for a reliable power supply without breaking the bank. However, it's essential to consider not just the price but also what each power supply offers in terms of features and performance. The lower price of the ARESGAME power supply may suggest fewer advanced features compared to the CORSAIR model, which could be a deciding factor for some users.
Build Quality and Design
In terms of build quality, the ARESGAME AGV Series 650W features a simple yet sturdy design with a SECC black coating casing and black cables. The design aims to provide a high-tech appearance while ensuring stable power output. In contrast, the CORSAIR RM850e boasts a fully modular design, allowing for more flexible cable management and a cleaner system setup. The CORSAIR also employs industrial-grade, 105°C-rated capacitors, which enhance its durability and reliability over time. While both power supplies are designed to deliver stable performance, the modularity and higher-rated components in the CORSAIR model may make it more appealing to users seeking long-lasting reliability.
Efficiency Ratings
The ARESGAME AGV Series holds an 80 PLUS Bronze certification, indicating it operates with about 85% efficiency under typical loads. This certification assures consumers of its energy-saving capabilities, but it does not match the efficiency of the CORSAIR RM850e, which is compliant with Cybenetics Gold efficiency standards. The CORSAIR's superior efficiency rating ensures that it delivers even better performance and lower energy costs over time. For users who prioritize energy savings and efficiency, the CORSAIR model is the superior choice.
Noise Levels
When it comes to noise levels, the ARESGAME AGV Series utilizes a 120mm fan designed for quiet operation, but it may not be as refined as the cooling system in the CORSAIR RM850e. The CORSAIR features a specially calculated fan curve that helps keep noise to a minimum, even under full load. This design consideration makes it a better option for those who value a quieter PC experience, particularly for gaming or professional use where noise levels can be distracting.
Modular Design
The modular design of the CORSAIR RM850e allows users to connect only the cables they need, which significantly simplifies installation and improves airflow within the case. This feature can also lead to a cleaner build, reducing clutter from unused cables. In contrast, the ARESGAME AGV Series is a non-modular power supply, meaning all cables are fixed, which can make cable management more challenging. For users who appreciate a tidy setup and want greater control over their cable management, the CORSAIR's fully modular design is a clear advantage.
Compatibility and Future-Proofing
The CORSAIR RM850e is designed to meet the latest standards with its ATX 3.1 certification and PCIe 5.1 compliance, ensuring compatibility with next-generation hardware. It includes a native 12V-2x6 connector, which is essential for modern GPUs that demand higher power. On the other hand, the ARESGAME AGV Series, while suitable for many existing setups, may not offer the same level of future-proofing. For gamers and PC enthusiasts looking to build or upgrade their systems with the latest components, the CORSAIR's advanced compatibility features make it a more viable long-term investment.
Warranty and Support
The ARESGAME AGV Series comes with a five-year warranty, providing a decent assurance of quality and support. However, the CORSAIR RM850e offers a more robust seven-year warranty, reflecting the manufacturer’s confidence in its product. Longer warranties can be indicative of superior build quality and reliability, which is an essential consideration for consumers who plan to use their power supply for many years. This extended warranty may sway buyers towards the CORSAIR model, particularly those investing in high-performance systems.
Which should you buy?
Deciding between the ARESGAME AGV Series 650W Power Supply and the CORSAIR RM850e ultimately hinges on your specific needs and budget. The ARESGAME is an excellent choice for those seeking a cost-effective and reliable power supply with a solid efficiency rating. However, if you prioritize features like modularity, superior noise control, and future-proofing through compliance with the latest standards, the CORSAIR RM850e emerges as the better option despite its higher price tag. The investment in the CORSAIR may pay off in the long run, particularly for gamers and PC builders who want the best performance and reliability from their components.
