Overview of the Products
In this comparison, we will examine the Apevia ATX-GX650W Galaxy and the CORSAIR RM850e power supplies. The Apevia is priced at $54.99, making it about 42% cheaper than the CORSAIR RM850e, which retails for $94.99. Both power supplies cater to gamers and high-performance builds, but they have different features and certifications that may influence your buying decision.
Power Output and Efficiency
The Apevia ATX-GX650W Galaxy offers a robust output of 650W with an 80+ Gold certification, ensuring efficient power delivery for gaming PCs. The efficiency rating means that it is designed to waste less energy in the form of heat, translating to lower electricity bills and a more environmentally friendly operation. In contrast, the CORSAIR RM850e boasts an even greater output of 850W, also with a Cybenetics Gold efficiency rating. This higher wattage allows for more headroom in power-hungry systems, making it a better option for users planning on utilizing multiple high-performance components.
Modular Design
The Apevia features a semi-modular design, which allows users to connect only the cables they need. This can improve airflow and cable management within the case. However, the CORSAIR RM850e takes this a step further with its fully modular design, meaning every cable can be detached. This full modularity allows for even cleaner builds and makes it easier to upgrade or replace components in the future. For those prioritizing aesthetics and convenience, the fully modular design of the CORSAIR might be more appealing.
Cooling and Noise Levels
The Apevia is equipped with a quiet 135mm thermally controlled fan that adjusts its speed based on temperature, helping to keep noise levels down while maintaining optimal cooling. On the other hand, the CORSAIR RM850e features a 120mm rifle bearing fan designed to keep noise to a minimum, even under full load. Both power supplies aim to operate quietly, but the CORSAIR’s specialized fan curve may provide a more consistent low-noise operation, especially in demanding situations.
Protection Features
When it comes to safety, the Apevia ATX-GX650W Galaxy incorporates several heavy-duty protections, including safeguards against short-circuits, over-voltage, over-power, and under-voltage. This ensures that your components remain safe during operation. Similarly, the CORSAIR RM850e also emphasizes reliability with 105°C-rated capacitors, which contribute to steady electrical performance and longevity. Both units provide robust protection, but the CORSAIR's higher quality capacitors may offer enhanced durability over time.
Connectivity Options
The Apevia supports a variety of connectors, including 1 x 20/24pin Main Power, 2 x P8(4+4P) ESP 12V, and multiple PCI-E and SATA connectors. Its ability to split connectors, such as the 8-pin CPU and PCI-E options, adds versatility for different motherboard and GPU configurations. In contrast, the CORSAIR RM850e comes with an extensive set of cables designed to support modern hardware, including a native 12V-2x6 connector for PCIe 5.1 compliance. This forward-thinking design ensures compatibility with the latest technology, making it a more suitable option for those building cutting-edge systems.
Warranty and Longevity
The CORSAIR RM850e comes with a seven-year warranty, reflecting the brand’s confidence in the product's durability and reliability. In contrast, the warranty details for the Apevia ATX-GX650W Galaxy are not specified, which may raise some questions regarding its longevity. A longer warranty can provide peace of mind, especially for high-investment components like power supplies, making the CORSAIR a more secure option in this regard.
User Experience and Aesthetics
Both the Apevia and the CORSAIR are designed with user experience in mind, offering features that facilitate easy installation and maintenance. The semi-modular design of the Apevia can appeal to budget-conscious users looking for a straightforward solution, while the fully modular design of the CORSAIR enhances flexibility and customization. Additionally, the aesthetic appeal of the units may differ; while both brands have a sleek design, the CORSAIR's modern look may be more attractive to gamers and PC builders who prioritize visual appeal in their setups.
Which should you buy?
Choosing between the Apevia ATX-GX650W Galaxy and the CORSAIR RM850e ultimately depends on your specific needs and budget. The Apevia is about 42% cheaper at $54.99, making it an attractive option for gamers on a budget or those with less demanding power requirements. However, if you’re building a high-performance system and require more power, better modularity, and longer warranty coverage, the CORSAIR RM850e at $94.99 offers superior features that may justify the higher price tag. Consider your system requirements, budget, and future upgrade plans when making your decision.
