SAMA B850 850W ATX Power Supply vs Lian Li Edge Series-850W Full Modular Power Supply-80 Plus Platinum-ATX 3.0

Overview of the SAMA B850 and Lian Li Edge Series

The SAMA B850 850W ATX Power Supply is priced at C$74.99, making it a budget-friendly option compared to the Lian Li Edge Series, which retails for C$195.95. Both power supplies are designed for high-performance systems, but they cater to different needs and budgets. The SAMA B850 is suitable for gamers and users looking for an affordable yet efficient power solution, while the Lian Li Edge Series offers premium features with higher efficiency and modularity.

Efficiency and Certification

The SAMA B850 boasts an 80 PLUS Bronze certification, indicating an efficiency of over 85% at typical loads. This level of efficiency helps save on energy costs, making it appealing for those conscious of power consumption. In contrast, the Lian Li Edge Series is certified at 80 PLUS Platinum, which signifies even higher efficiency. The Platinum rating indicates that it can achieve efficiencies above 90%, making it an excellent choice for users prioritizing energy savings and performance.

Modular Design and Cable Management

The SAMA B850 features sleek black flat cables that enhance cable management while improving airflow within the case. This design is particularly beneficial for those who want a clean and organized build. On the other hand, the Lian Li Edge Series is fully modular, allowing users to connect only the cables they need, thereby reducing clutter and improving airflow even further. This modular capability is a significant advantage for advanced users who appreciate customizability and optimal case management.

Cooling Solutions

The SAMA B850 is equipped with a temperature-controlled fan that ensures quiet operation while providing adequate cooling performance. This feature is essential for users who want a silent experience during gaming or intensive tasks. The Lian Li Edge Series, while not explicitly mentioning fan noise, is designed with a 120mm FDB fan and includes a fanless mode. This suggests that it can operate silently during low loads, catering to those who require a quiet environment for their PC operations.

Compatibility and Future-Proofing

Both power supplies are ATX 3.1 compliant and support PCIe 5.1, making them ready for the latest motherboards and high-end graphics cards, including the RTX 4090/50 series. The SAMA B850 specifically mentions 450W power delivery for PCIe 5.1, which ensures it can effectively power cutting-edge components. The Lian Li Edge Series also supports PCIe 5.1 with in-house R&D 12V-2x6 alloy copper soldered terminals, which may enhance reliability and performance. Users looking to build or upgrade to the latest hardware will find both units capable in this aspect.

Warranty and Protection Features

The SAMA B850 comes with a 3-year warranty and includes multiple protection features such as Over Voltage Protection (OVP), Over Current Protection (OCP), and Short Circuit Protection (SCP). This comprehensive protection ensures peace of mind for users, particularly those installing their first power supply. In contrast, the Lian Li Edge Series also includes extensive protections like Over Voltage Protection, Over Temperature Protection (OTP), and Under Voltage Protection (UVP), but it does not specify a warranty term. The lack of a clear warranty may be a consideration for potential buyers looking for long-term reliability.

Design Aesthetics

The aesthetic appeal of power supplies can be a deciding factor for many builders. The SAMA B850 features a sleek black design that fits well within most builds. In comparison, the Lian Li Edge Series offers a unique L-shape design that is specifically tailored for dual chamber cases. However, it is essential to note that users with non-dual chamber cases should ensure compatibility, as it requires a case height of no more than 400mm. The distinct design of the Lian Li may attract users looking for innovative aesthetics, but it could limit its versatility in certain setups.

Which should you buy?

When deciding between the SAMA B850 and the Lian Li Edge Series, consider your specific needs and budget. The SAMA B850 is an excellent choice for budget-conscious users who still want a reliable and efficient power supply. Its lower price point and adequate features make it suitable for mainstream gaming and general use. However, if you require higher efficiency, superior modularity, and premium features for a high-performance build, the Lian Li Edge Series justifies its higher price with its 80 PLUS Platinum certification and advanced design. Ultimately, the best choice depends on whether you prioritise cost-effectiveness or cutting-edge performance and efficiency.
