Overview of the Products
The CORSAIR RM850x Fully Modular Low-Noise ATX Power Supply and the Lian Li Strimer Wireless 24-Pin RGB Motherboard Power Extension Cable serve distinctly different purposes in your PC build. The RM850x is designed to provide reliable power, while the Strimer is focused on enhancing aesthetics with RGB lighting.
The RM850x comes at a current price of $161.93, whereas the Lian Li Strimer is priced at $69.99. This means the Strimer is about 57% cheaper than the RM850x. However, comparing these products directly is not straightforward, as they cater to different needs within the realm of PC building.
Design and Aesthetics
When it comes to design, the Lian Li Strimer shines with its RGB features. It includes a wireless controller for managing lighting effects, which enhances the visual appeal of your setup. The Strimer's addressable RGB cable allows for customizable lighting and creates a more immersive effect with improved coverage on the sides.
In contrast, the RM850x focuses on functionality over flashiness. Its embossed cables with low-profile combs are designed for flexibility and ease of installation, ensuring a neat appearance inside your case. While it may not have RGB features, the RM850x’s sleek black design is classic and professional, making it suitable for any build.
Performance and Efficiency
The RM850x excels in performance and efficiency. It is Cybenetics Gold-certified, boasting up to 91% efficiency. This rating indicates lower power consumption, which translates to less heat generation and quieter operation. The power supply also includes a 140mm fan for cooling, ensuring that your system remains efficient and quiet during operation.
On the other hand, the Lian Li Strimer is not a stand-alone power supply and relies on existing power sources. Its performance is dependent on the motherboard it connects to. While it offers enhanced lighting control and visual effects via its 2.4 GHz wireless technology, it does not contribute to the overall power efficiency of the system.
Features and Functionality
The CORSAIR RM850x is packed with features aimed at providing reliable power delivery. It is fully modular, allowing users to connect only the cables they need, which simplifies installation and improves airflow within the case. Additionally, the native 12V-2x6 connector ensures compatibility with the latest graphics cards, eliminating the need for adapters.
In contrast, the Lian Li Strimer comes with a wireless controller that is essential for operating the RGB lighting. It allows for quick software setup through the L-Connect 3 software, where users can customize fan speeds and monitor system temperatures. This feature is particularly beneficial for users looking to optimize their cooling solutions while enjoying visually appealing lighting.
Compatibility
The CORSAIR RM850x is compliant with the ATX 3.1 power standard, which means it supports the latest hardware requirements, including PCIe 5.1 connections. This makes it a future-proof choice for gamers and PC builders looking to invest in high-performance components.
The Lian Li Strimer, while versatile, is limited to being compatible with standard 24-pin motherboard headers. It can work with ATX, mATX, and ITX motherboards, making it a flexible option for various builds. However, its compatibility is restricted to enhancing the visual aspects rather than influencing hardware performance.
User Experience
The RM850x is backed by a ten-year warranty, reflecting Corsair's confidence in the durability and reliability of their product. Users report a seamless installation process thanks to the fully modular design, which leads to a tidy build and excellent airflow.
Conversely, the Lian Li Strimer offers a unique user experience with its lighting capabilities. The wireless controller enhances ease of use, allowing users to change lighting effects effortlessly. However, it does require additional setup with the L-Connect 3 software, which may be a slight drawback for those who prefer straightforward plug-and-play components.
Price Comparison
The price difference between the two products is significant. The CORSAIR RM850x is priced at $161.93, while the Lian Li Strimer costs $69.99. This makes the Strimer about 57% less expensive than the RM850x. The price point of the RM850x reflects its premium features and efficiency ratings, while the Strimer’s cost is indicative of its specialization in aesthetics rather than performance.
While both products have their merits, the RM850x justifies its higher price with superior efficiency, performance, and a longer warranty period. The Strimer, although cheaper, serves a different purpose as a visual enhancement rather than a crucial component for power delivery.
Which should you buy?
Choosing between the CORSAIR RM850x and the Lian Li Strimer ultimately depends on your needs. If you are focused on building a reliable, high-performance PC, the RM850x is the clear choice due to its efficiency, modular design, and compatibility with modern hardware. However, if your priority lies in enhancing your PC's aesthetics with RGB lighting, the Lian Li Strimer offers a compelling and cost-effective solution. Consider your specific requirements and budget before making a decision.
