Apevia ATX-GX650W Galaxy 650W 80+ Gold Certified vs CORSAIR RM850x Fully Modular Low-Noise ATX Power

Overview of the Products

When it comes to power supplies, the Apevia ATX-GX650W Galaxy 650W and the CORSAIR RM850x stand out in their respective categories. The Apevia model is priced at $54.99, making it a budget-friendly option, while the CORSAIR unit is more premium at $161.93. The key difference in price is about 194%, which reflects variations in features and power capabilities.

Power Output Comparison

The Apevia ATX-GX650W Galaxy provides a total output of 650W, sufficient for most gaming PCs and high-performance builds. In contrast, the CORSAIR RM850x offers a higher output of 850W, catering to more demanding setups, particularly those with powerful graphics cards. This additional power can be crucial for gamers and professionals running multiple high-performance components simultaneously.

Efficiency Ratings

Efficiency is crucial for reducing energy consumption and maintaining cooler temperatures. The Apevia unit is certified 80+ Gold, which indicates it operates with high efficiency. On the other hand, the CORSAIR RM850x boasts a Cybenetics Gold certification, rated for up to 91% efficiency. This higher efficiency can lead to lower electricity bills and better overall system performance over time.

Modularity and Cable Management

The Apevia ATX-GX650W features a semi-modular design, allowing users to connect only the necessary cables for their setups. This can improve airflow and cable management. Conversely, the CORSAIR RM850x is fully modular, meaning every cable can be detached, providing even greater flexibility and a cleaner build. Users looking for optimal cable management may find the fully modular design of the CORSAIR unit preferable.

Noise Levels

Noise is a significant concern for many PC builders. The Apevia power supply is equipped with a quiet 135mm thermally controlled fan that adjusts its speed according to the temperature, ensuring minimal noise during operation. The CORSAIR RM850x, with its 140mm FDB fan, is also designed for low noise, but it emphasizes quiet operation even more thanks to its fully modular design, which reduces cable clutter and improves airflow.

Compatibility and Connectivity

The Apevia ATX-GX650W is compatible with various components, including dual and quad-core CPUs, and supports SLI/Crossfire configurations. It includes multiple connectors, such as 1 x 20/24 pin Main Power and 4 x SATA, which cater to diverse system requirements. The CORSAIR RM850x excels in this area by being ATX 3.1 compliant and offering a native 12V-2x6 connector, ensuring it is future-proof and compatible with the latest graphics cards without requiring adapters.

Build Quality and Durability

While both power supplies are constructed for reliability, they differ in their components. The Apevia model incorporates a double forward converter design and large Japanese capacitors, which contribute to its stability. In contrast, the CORSAIR RM850x utilizes 100% Japanese 105°C-rated electrolytic capacitors, known for their longevity and performance. This could make the CORSAIR unit a more durable option in the long run.

Warranty and Support

Warranty coverage is another important factor to consider. The Apevia ATX-GX650W does not specify a warranty period in the available data, which could be a drawback for potential buyers seeking assurance. In contrast, the CORSAIR RM850x comes with a ten-year warranty, reflecting the brand's confidence in its product's durability and performance. This extended warranty may provide peace of mind for users investing in a more expensive power supply.

Which should you buy?

Choosing between the Apevia ATX-GX650W Galaxy and the CORSAIR RM850x ultimately depends on your specific needs and budget. If you're looking for a cost-effective power supply that still offers solid performance for a gaming PC, the Apevia model at $54.99 is a reasonable choice. However, if you require higher wattage, superior efficiency, and durability, the CORSAIR RM850x at $161.93 is worth the investment, especially with its extended warranty and fully modular design.
