Pricing Comparison
When comparing the prices of the CORSAIR RM850e and the ASUS ROG Strix 1200W Platinum, there is a significant difference. The RM850e is priced at C$184.99, while the ROG Strix Platinum is considerably higher at C$329.99. This C$145 price gap indicates that the ASUS power supply targets high-end users who may require additional features and capabilities, while the Corsair model appeals to those seeking a reliable and efficient choice at a more affordable price point.
Power Efficiency
Power efficiency is a crucial factor for many users, particularly gamers and PC builders. The ASUS ROG Strix Platinum stands out with its GaN MOSFET technology, delivering up to 30% superior power efficiency compared to traditional designs. This feature, combined with its 80 PLUS Platinum certification, ensures that the power supply operates efficiently under load. In contrast, while the CORSAIR RM850e does not specify its efficiency rating, it is also compliant with the ATX 3.1 standard, indicating respectable performance. However, the explicit efficiency metrics of the ROG Strix Platinum make it the more appealing choice for efficiency-conscious users.
Modular Design
Both the CORSAIR RM850e and the ASUS ROG Strix Platinum feature modular designs, which allow users to connect only the cables necessary for their builds. The fully modular cabling of the RM850e promotes a cleaner installation and better airflow, which is essential for optimal cooling. On the other hand, the ROG Strix Platinum not only offers a modular design but also comes equipped with a native 12V-2x6 connector specifically for next-gen graphics cards. This added compatibility can be particularly advantageous for users planning to build high-performance gaming rigs.
Noise Levels
Noise levels are a common concern when selecting a power supply. The CORSAIR RM850e is designed with a 120mm rifle bearing fan that keeps noise levels down, even under full load, thanks to a specially calculated fan curve. In comparison, the ASUS ROG Strix Platinum features a dual ball fan bearing design that can last up to twice as long as traditional sleeve bearings and incorporates 0dB technology, enabling silent operation during light gaming. Therefore, while both models aim for low noise, the ASUS power supply offers advanced features that cater to users who prioritize silent performance.
Cooling Solutions
Effective cooling solutions are vital for maintaining performance and longevity in power supplies. The ASUS ROG Strix Platinum is equipped with large heatsinks that cover critical components, providing lower temperatures and reduced noise compared to reference designs. This is complemented by its dual fan bearing system. The CORSAIR RM850e, while it does incorporate a well-designed fan, does not highlight the extent of its cooling capabilities as prominently as the ROG Strix Platinum does. For users looking for exceptional cooling, the ASUS model may offer more reassurance.
Warranty and Support
When it comes to warranty, the ASUS ROG Strix Platinum boasts an impressive 10-year warranty, a testament to its build quality and reliability. This extended warranty provides peace of mind for users investing in a high-performance power supply. In contrast, the warranty details for the CORSAIR RM850e are not specified in the provided data. This lack of information could be a deciding factor for potential buyers who value strong warranty support when making their purchase.
Compatibility with Next-Gen Hardware
For those building systems with the latest technology, compatibility is critical. The ASUS ROG Strix Platinum is ATX 3.1 compatible and features a PCIe 5.0 ready connector, making it an excellent choice for users planning to utilize next-gen graphics cards. The CORSAIR RM850e is also ATX 3.1 certified, meaning it can support PCIe 5.1 platforms, but it does not explicitly mention a readiness for the latest connectors. Users looking to future-proof their builds may find the ASUS option more appealing due to its emphasis on compatibility with cutting-edge hardware.
Which should you buy?
In conclusion, the choice between the CORSAIR RM850e and the ASUS ROG Strix 1200W Platinum ultimately depends on your specific needs and budget. The CORSAIR RM850e is a cost-effective option for those seeking reliable performance without breaking the bank. However, for users demanding superior efficiency, advanced cooling, and exceptional warranty support, the ASUS ROG Strix Platinum justifies its higher price with a range of premium features. If you are building a high-performance gaming setup that requires the latest technology, the ASUS model may be the better investment. Conversely, if you’re looking for a solid and efficient power supply at a lower price point, the CORSAIR RM850e is an excellent choice.
