Price Comparison
The CORSAIR RM1000x is priced at C$224.98, while the ASUS ROG Strix 1200W Platinum comes in at C$329.99. This price difference of C$105.01 reflects the varying features and performance levels offered by each power supply. The RM1000x is more budget-friendly, targeting users who require a reliable power source without breaking the bank. In contrast, the ROG Strix Platinum caters to gamers and enthusiasts seeking top-tier performance and advanced technology, justifying its higher price point.
Efficiency and Certification
The CORSAIR RM1000x boasts a Cybenetics Gold certification with an efficiency rating of up to 91%. This level of efficiency translates to lower power consumption and cooler operating temperatures, making it a solid choice for energy-conscious users. On the other hand, the ASUS ROG Strix Platinum is 80 PLUS Platinum certified, which indicates its superior power efficiency. The ROG Strix Platinum utilises low-ESR capacitors and premium components to achieve industry-leading efficiency, ensuring that it delivers power effectively while maintaining lower temperatures and noise levels.
Modular Design
Both the CORSAIR RM1000x and ASUS ROG Strix Platinum feature fully modular designs, allowing users to connect only the cables required for their specific builds. This design simplifies cable management and enhances airflow within the case. However, the RM1000x stands out with its ultra-flexible embossed cables that not only look aesthetically pleasing but also ease the installation process. In contrast, the ROG Strix Platinum's organized internal layout, aided by GaN MOSFET technology, contributes to cooler operation, further enhancing its modular design benefits.
Compatibility
The CORSAIR RM1000x is compliant with the ATX 3.1 power standard, which supports PCIe 5.1 and is resistant to transient power spikes, ensuring it can adequately power the latest hardware. It also features a native 12V-2x6 connector, making it compatible with the newest graphics cards without requiring an adapter. Similarly, the ASUS ROG Strix Platinum is also ATX 3.1 compliant and includes a native 12V-2x6 connector, ensuring it is ready for next-gen graphics cards. Both power supplies are well-equipped for future-proofing builds.
Noise Levels
The CORSAIR RM1000x is designed for low noise operation, making it an excellent choice for users who prioritise a quiet system. Its design leads to reduced noise levels, ideal for quiet computing environments. The ASUS ROG Strix Platinum takes this a step further with its 0dB technology, allowing for silent operation during light gaming sessions. This feature makes the ROG Strix Platinum particularly appealing for gamers who desire a quiet experience when not under heavy load, showing a notable advantage in terms of noise management.
Cooling Solutions
Cooling is an essential aspect of power supply performance, and both models incorporate advanced solutions. The CORSAIR RM1000x utilises its efficient design to maintain lower temperatures, while the ASUS ROG Strix Platinum features large ROG heatsinks that cover critical components, enhancing thermal performance. This robust cooling system allows the ROG Strix Platinum to operate at lower temperatures and noise levels compared to reference designs, making it a superior choice for high-performance gaming rigs that demand reliable cooling.
Warranty and Reliability
The CORSAIR RM1000x does not specify a warranty period, which can be a critical factor for buyers concerned about long-term reliability. In contrast, the ASUS ROG Strix Platinum comes with an impressive 10-year warranty, signalling confidence in its durability and performance. This extended warranty can provide peace of mind for users investing in a high-end power supply, as it suggests a commitment to quality and reliability from ASUS.
Which should you buy?
Choosing between the CORSAIR RM1000x and the ASUS ROG Strix 1200W Platinum ultimately depends on your specific needs and budget. If you are looking for a more affordable, efficient power supply that provides reliable performance and low noise, the CORSAIR RM1000x is an excellent choice. However, if you require top-tier efficiency, advanced cooling solutions, and features tailored for gaming performance—along with a longer warranty—then the ASUS ROG Strix Platinum stands out as the better option despite its higher price tag.
