CORSAIR SF850 vs Lian Li Edge Series-850W Full Modular Power Supply-80 Plus Platinum-ATX 3.0

Price Comparison

The CORSAIR SF850 is priced at C$279.99, while the Lian Li Edge Series-850W is significantly cheaper at C$195.95. This represents a difference of C$84.04, making the Lian Li a more budget-friendly option. For users looking for an efficient power supply without breaking the bank, the Lian Li provides excellent value, especially considering it still boasts an 80 PLUS Platinum rating. However, the higher price of the CORSAIR may be justified for those who prioritize brand reputation and specific features that may enhance performance.

Power Efficiency

Both the CORSAIR SF850 and the Lian Li Edge Series are rated at 80 PLUS Platinum, signifying high energy efficiency. This means that both power supplies operate at least 90% efficiency at 50% load, which is crucial for reducing electricity consumption and heat output. The focus on efficiency can lead to long-term savings in energy costs. However, the CORSAIR SF850 stands out with its additional features like ATX 3.0 compliance, indicating it is designed to support the latest hardware demands more effectively.

Form Factor and Compatibility

The CORSAIR SF850 is designed as a compact SFX power supply, making it ideal for small-form-factor builds. This design allows it to fit into tight spaces within cases, thus catering to users who are constrained by size. On the other hand, the Lian Li Edge Series is an ATX power supply that requires a case with sufficient height, specifically noting that the case height should not exceed 400mm if not using a dual chamber. Therefore, while both power supplies are modular, the choice of form factor could significantly impact compatibility based on your PC case.

Cable Management

The CORSAIR SF850 features fully modular Type-5 Micro-Fit PSU connectors, allowing for flexible cabling and tidy cable management. This is particularly beneficial in smaller cases where space is at a premium, as it helps reduce clutter. The Lian Li Edge Series is also fully modular but lacks the specific mention of micro-fit connectors, which might make cable management slightly less efficient. However, it still offers a comprehensive set of connectors to accommodate various components, making it versatile for many builds.

Cooling Solutions

Cooling performance is critical in high-demand systems, and both power supplies are equipped with effective cooling solutions. The CORSAIR SF850 features a 92mm PWM cooling fan, engineered for powerful yet quiet operation. This is advantageous for users who are sensitive to noise levels in their systems. Meanwhile, the Lian Li Edge Series uses a 120mm FDB fan and offers a fanless mode, allowing for silent operation under low loads. This feature can be particularly appealing to gamers and professionals who prefer a quieter environment during operation.

Reliability and Build Quality

Reliability is a key consideration when selecting a power supply. The CORSAIR SF850 is built with 105°C rated Japanese capacitors, ensuring robust performance and longevity. This quality is often associated with high-end components, making it a reliable choice for users who demand stability. On the other hand, the Lian Li Edge Series also emphasizes reliability with its active PFC and various protection features, including OCP, OVP, and OTP. Both products promise durability, but the specific use of high-grade capacitors in the CORSAIR may give it an edge in long-term reliability.

Additional Features

The Lian Li Edge Series includes a built-in USB expansion hub with four internal USB 2.0 headers, a feature absent in the CORSAIR SF850. This addition can be particularly useful for users who require more connectivity options within their systems. In contrast, the CORSAIR SF850 focuses primarily on efficiency and performance, offering features that cater to those who may prioritize power management and cooling. The choice between these two will depend on whether additional connectivity is a priority for the user.

Which should you buy?

In summary, the choice between the CORSAIR SF850 and the Lian Li Edge Series-850W largely depends on your specific needs and budget. If you are looking for a high-performance, compact power supply with superior build quality and cooling efficiency, the CORSAIR SF850 is worth the investment at C$279.99. However, if you are more budget-conscious and still want a reliable, efficient power supply with additional connectivity options, the Lian Li Edge Series at C$195.95 offers excellent value. Ultimately, both power supplies have their strengths, making them suitable for different types of users and builds.
