ASUS ROG Thor 1200W Platinum III PSU vs CORSAIR RM850e Fully Modular Low-Noise ATX Power

Price Comparison

The ASUS ROG Thor 1200W Platinum III PSU is priced at $432.35, while the CORSAIR RM850e comes in at a significantly lower price of $94.99. This makes the CORSAIR model about 78% cheaper than the ASUS offering. While the price difference is substantial, it reflects the different market segments and features each power supply provides. The ROG Thor is positioned as a high-end PSU with specialized features aimed at gaming enthusiasts and power users, whereas the RM850e caters to those looking for reliable, cost-effective performance.

Efficiency Ratings

The ASUS ROG Thor boasts an impressive 80 PLUS Platinum certification, indicating exceptional power efficiency. This certification ensures that the PSU operates at up to 92% efficiency at 50% load. In contrast, the CORSAIR RM850e is rated with Cybenetics Gold efficiency, which still provides commendable performance but falls short compared to the Platinum standard. This means that while both power supplies deliver reliable performance, the ROG Thor offers superior efficiency, making it a better choice for users who prioritize energy savings and performance.

Design and Build Quality

The ASUS ROG Thor features a fully aluminum enclosure and ROG heatsinks, which contribute to superior cooling and a visually striking design. It also includes a magnetic OLED display for real-time power draw monitoring, adding a touch of high-tech flair. On the other hand, the CORSAIR RM850e is designed with practicality in mind, featuring a compact casing and a fully modular setup that enhances cable management. While both models are well-built, the ASUS ROG Thor stands out for its aesthetic and feature-rich design, appealing to gamers and PC builders looking for a premium look.

Cooling and Noise Levels

Cooling performance is a key consideration for high-performance power supplies. The ASUS ROG Thor includes dual-ball fan bearings, which can last up to twice as long as typical sleeve bearing designs, ensuring longevity and efficient cooling. Its Turbo Mode allows for extended power excursions, making it suitable for demanding gaming sessions. In contrast, the CORSAIR RM850e uses a 120mm rifle bearing fan that operates quietly even under full load, making it ideal for users looking for a low-noise solution. While both power supplies are designed to manage heat effectively, the ASUS model provides advanced cooling features that may benefit overclockers and high-performance systems.

Modular Design and Connectivity

The CORSAIR RM850e features a fully modular design, allowing users to connect only the cables necessary for their specific build. This design choice simplifies the installation process and enhances case airflow. The ASUS ROG Thor, while also modular, includes etched cables made from pliable premium materials, which ensure better safety and easier management. Both power supplies comply with the ATX 3.1 standard, but the CORSAIR model's modularity may appeal more to those working on compact builds or seeking a cleaner cable setup.

Warranty and Support

The ASUS ROG Thor comes with an impressive 10-year warranty, reflecting the brand's confidence in its product's reliability and durability. This extended warranty can be a significant factor for users who want peace of mind with their investment. The CORSAIR RM850e offers a slightly shorter, yet still respectable, seven-year warranty. Both warranties indicate a commitment to quality, but the longer warranty period of the ASUS PSU may sway long-term users who are willing to invest more upfront for enhanced support.

Target Audience

The ASUS ROG Thor is clearly designed for high-end gaming enthusiasts and power users who demand superior performance and efficiency. Its advanced features, such as the GPU-First voltage stabilizer and real-time monitoring display, cater to users who want to maximize their system's potential. Conversely, the CORSAIR RM850e is targeted towards mainstream users who require a dependable power supply for their builds without the need for extravagant features. Its lower price point and efficient performance make it an attractive option for budget-conscious gamers or those building standard systems.

Which should you buy?

Choosing between the ASUS ROG Thor 1200W Platinum III PSU and the CORSAIR RM850e ultimately depends on your specific needs and budget. If you are a gaming enthusiast or power user willing to invest in high-end features, the ASUS model offers superior efficiency, advanced cooling, and a premium design, making it worth the higher price at $432.35. However, if you are looking for a reliable, efficient PSU at a fraction of the cost, the CORSAIR RM850e at $94.99 provides excellent value without compromising on essential performance.
