ASRock PRO-650G Power Supply - 650W 80 Plus Gold vs CORSAIR RM850e Fully Modular Low-Noise ATX Power

Overview of Power Supplies

When considering power supplies for your PC, the ASRock PRO-650G and the CORSAIR RM850e present two solid options, each catering to different needs. The ASRock PRO-650G is priced at $49.99, making it about 17% cheaper than the CORSAIR RM850e, which retails for $94.99. Both power supplies are ATX 3.1 certified, which means they are compatible with modern components, but they offer distinct features tailored to varying user requirements.

Efficiency Ratings

The ASRock PRO-650G boasts an 80 PLUS Gold certification, delivering up to 90% energy efficiency. This level of efficiency can significantly reduce power consumption and heat output, making it ideal for cost-effective operation. On the other hand, the CORSAIR RM850e also holds a Cybenetics Gold efficiency rating, ensuring reliable power delivery with minimal waste. Both power supplies promise energy-efficient performance, but the ASRock's rating may appeal more to budget-conscious users looking for operational savings.

Power Output and Stability

In terms of power output, the ASRock PRO-650G provides a stable 650W with a +12V rail delivering 54.1A, which is sufficient for most mid-range gaming and productivity setups. Alternatively, the CORSAIR RM850e offers a higher total power output of 850W, making it suitable for high-performance systems that may include demanding graphics cards and processors. Users planning to build or upgrade to high-end systems may find the extra power capacity of the CORSAIR appealing.

Design and Modularity

The design of the ASRock PRO-650G features a flat cable layout that simplifies cable management and enhances airflow within the case. While this is beneficial for overall aesthetics and cooling, it lacks modular cabling. In contrast, the CORSAIR RM850e is fully modular, allowing users to connect only the cables necessary for their builds. This modularity not only streamlines installation but also reduces clutter, which can be a significant advantage for users who prioritize a clean build.

Noise Levels

Noise levels are a critical factor for many PC builders, especially those who prefer quieter operations. The ASRock PRO-650G includes a quiet 120mm fan that maintains low noise levels during operation, making it a good choice for silent builds. The CORSAIR RM850e also features a 120mm rifle bearing fan that is designed to minimize noise, even under full load. Both models strive for quiet operation, but the specific fan designs may yield varying results in real-world scenarios.

Build Quality and Components

The ASRock PRO-650G is constructed with all-Taiwanese capacitors, which typically signify quality and durability. This is complemented by comprehensive protection features, including over-voltage and short-circuit protections. The CORSAIR RM850e, on the other hand, utilizes industrial-grade, 105°C-rated capacitors which further enhance its reliability and longevity. Users looking for robust build quality may lean towards the CORSAIR, particularly due to its higher rated components and longer warranty period of seven years compared to the three years offered by ASRock.

Warranty and Support

Warranty and manufacturer support play a significant role in the overall value of a power supply. The ASRock PRO-650G is backed by a three-year warranty, providing reasonable assurance for users. However, the CORSAIR RM850e offers a more extensive seven-year warranty, which can be a deciding factor for those seeking long-term reliability and peace of mind. The longer warranty period demonstrates confidence in the product’s durability, making it more appealing for users planning on long-term use.

Which should you buy?

Ultimately, the decision between the ASRock PRO-650G and the CORSAIR RM850e depends on your specific needs and budget. If you require a cost-effective power supply for a mid-range setup, the ASRock PRO-650G at $49.99 offers great value with reliable performance and efficiency. However, if you are building a high-performance system and want the benefits of higher power output, modular cabling, and extended warranty, the CORSAIR RM850e at $94.99 is the superior choice. Each power supply has its strengths, so consider your specific requirements to make the best decision.
