ASUS ROG Strix 1200W Platinum vs CORSAIR RM850x Fully Modular Low-Noise ATX Power

Overview of the ASUS ROG Strix 1200W Platinum and CORSAIR RM850x

The ASUS ROG Strix 1200W Platinum is designed for high-performance gaming, while the CORSAIR RM850x focuses on delivering quiet, dependable power. With the ASUS priced at $264.99 and the CORSAIR at $161.93, the ROG Strix is approximately 63% more expensive than the RM850x. This stark price difference sets the stage for a comparison of features, performance, and value for gamers and PC builders alike.

Power Efficiency and Certification

The ASUS ROG Strix 1200W Platinum is 80 PLUS Platinum certified, which reflects its superior energy efficiency. This certification indicates that the power supply can maintain an efficiency rate of over 90% at various loads, ensuring less energy waste and lower electricity bills. On the other hand, the CORSAIR RM850x holds a Cybenetics Gold certification, boasting up to 91% efficiency. While both units provide excellent performance, the ROG Strix's Platinum rating suggests it may offer slightly superior energy savings over time compared to the RM850x.

Modular Design and Cable Management

The ROG Strix 1200W Platinum features a fully modular design, allowing users to connect only the cables they need. This results in a cleaner build and improved airflow within the case. The RM850x also boasts a fully modular design with ultra-flexible embossed cables, facilitating easy installation. Both power supplies excel in this aspect, but the ASUS has an edge with its emphasis on organization and reduced internal heat, thanks to its GaN MOSFET technology, which can enhance power efficiency by up to 30%.

Cooling and Noise Levels

In terms of cooling, the ASUS ROG Strix is equipped with large heatsinks that cover critical components, which contribute to lower temperatures and reduced noise compared to standard designs. The dual ball fan bearings in the ROG Strix are designed to last up to twice as long as traditional sleeve bearings. Conversely, the CORSAIR RM850x employs a 140mm FDB fan that provides low noise cooling, ensuring a quiet operation. While both power supplies aim to minimize noise, the ASUS's advanced cooling solutions may provide a slight advantage for those seeking quiet operation during heavy gaming sessions.

Compatibility and Future-Proofing

The ROG Strix 1200W Platinum is compliant with the ATX 3.1 standard, which enhances voltage and current regulation. It also features a native 12V-2x6 connector, ensuring compatibility with next-gen graphics cards, making it a solid choice for future-proofing high-end gaming rigs. The RM850x also complies with the ATX 3.1 standard and supports PCIe 5.1, making it equally suited for modern hardware. Both power supplies are well-equipped for today's demanding components, but the additional power capacity of the ASUS may appeal more to those with high-performance setups.

Warranty and Reliability

The ASUS ROG Strix comes with a generous 10-year warranty, reflecting the brand's confidence in its durability and reliability. The CORSAIR RM850x also offers a solid 10-year warranty, ensuring peace of mind for users. Both warranties are comparable; however, the reputation of ASUS in the gaming community may sway some users in favor of the ROG Strix, especially if they prioritize long-term reliability.

User Experience and Installation

Both power supplies are user-friendly, with fully modular designs that simplify the installation process. The ROG Strix's emphasis on an organized layout can enhance the overall building experience, particularly for those who value aesthetics and airflow. The RM850x, with its embossed cables and low-profile combs, aims to make installation straightforward and visually pleasing as well. Users may find equal satisfaction in the ease of installation for both units, but the aesthetics of the ASUS may be more appealing to gamers who prioritize visual presentation.

Which should you buy?

Choosing between the ASUS ROG Strix 1200W Platinum and the CORSAIR RM850x largely depends on your specific needs and budget. If you're looking for top-tier performance, superior power efficiency, and advanced cooling technology, the ROG Strix may justify its higher price at $264.99. However, if you seek a reliable, cost-effective option with solid performance and a lower price of $161.93, the RM850x stands out as an excellent choice. Ultimately, either power supply will serve you well, but your decision should align with your gaming needs, system requirements, and budget constraints.
