ASUS ROG Strix 1200W Platinum vs CORSAIR RM Series , RM650, Fully Modular Power Supply

Overview of the ASUS ROG Strix 1200W Platinum

The ASUS ROG Strix 1200W Platinum is a high-performance power supply designed for gamers seeking top-tier stability and efficiency. Priced at $264.99, it leverages GaN MOSFET technology to deliver superior power efficiency, potentially improving performance by up to 30%. This power supply is compliant with the ATX 3.1 standard, ensuring it can handle the demands of modern gaming rigs while providing a 10-year warranty for added peace of mind. Its “GPU-FIRST” voltage sensing technology enhances delivery to graphics cards, ensuring smooth gameplay.

Overview of the CORSAIR RM Series

The CORSAIR RM Series, specifically the RM650 model, is a solid choice for users looking for a reliable power supply at a lower price point of $138.31. This model is fully modular, allowing users to connect only the necessary cables, which can help in maintaining a clean build. With an 80 PLUS Gold certification, it offers efficient power delivery, and its 140mm rifle bearing fan operates quietly, thanks to a specially calculated fan curve. The RM650 also comes with a 10-year warranty, ensuring durability over time.

Performance Comparison

When it comes to performance, the ASUS ROG Strix excels with its GaN MOSFET technology, which can increase power efficiency by up to 30%. This is particularly beneficial for high-end gaming setups that demand a steady power supply. In contrast, the CORSAIR RM650, while efficient with its 80 PLUS Gold certification, operates at a slightly lower efficiency level than the ROG Strix Platinum. Users seeking peak performance in gaming will likely prefer the ROG Strix for its advanced features, including the GPU-FIRST voltage sensing.

Design and Build Quality

The ASUS ROG Strix 1200W Platinum is designed with large heatsinks that cover critical components, leading to lower temperatures and reduced noise levels, enhancing the overall gaming experience. Its dual ball fan bearings are designed to last twice as long as conventional sleeve bearings, which is a crucial factor for longevity. On the other hand, the CORSAIR RM650 features a 140mm rifle bearing fan that minimizes noise even under load. Both power supplies are built to high standards, but the ROG Strix has an edge in cooling technology.

Compatibility and Connectivity

The ASUS ROG Strix 1200W Platinum is equipped with a native 12V-2x6 connector, making it PCIe 5.0 ready, which is ideal for future-proofing against upcoming graphics card demands. It is also compliant with the ATX 3.1 standard, ensuring enhanced voltage and current regulation. The CORSAIR RM650, while less advanced in this regard, features triple EPS12V connectors, allowing for compatibility with most modern graphics cards and motherboards. For users focused on the latest technologies, the ROG Strix provides superior connectivity options.

Noise Levels

In terms of noise levels, both power supplies offer features aimed at reducing operation noise. The ASUS ROG Strix incorporates 0dB technology, allowing for silent operation during light gaming. Meanwhile, the CORSAIR RM650 has a zero RPM fan mode, providing near-silent operation at low to medium loads. Gamers who prioritize a quiet environment during gameplay will find both options appealing, but the ROG Strix may offer a slightly quieter experience during low-demand scenarios.

Warranty and Support

Both the ASUS ROG Strix and the CORSAIR RM650 come with a 10-year warranty, reflecting the manufacturers' confidence in their products' durability and reliability. This long warranty period is a significant advantage for consumers, as it offers assurance against potential defects and failures over time. However, the support experience may vary based on user reports and brand reputation, which are important considerations when choosing between the two.

Which should you buy?

Ultimately, the choice between the ASUS ROG Strix 1200W Platinum and the CORSAIR RM650 will depend on your specific needs and budget. The ROG Strix, priced at $264.99, is about 92% more expensive than the RM650 at $138.31, but it offers advanced features such as GaN MOSFET technology, enhanced cooling, and superior power efficiency. If you are building a high-end gaming rig and require the best performance and efficiency, the ASUS ROG Strix is the way to go. Conversely, if you are looking for a cost-effective solution that still delivers reliable performance, the CORSAIR RM650 is an excellent choice.
