Mean Well LRS-150-24 Switching Power Supply vs Lian Li Edge Series-850W Full Modular Power Supply-80 Plus Platinum-ATX 3.0

Overview of the Mean Well LRS-150-24 and Lian Li Edge Series-850W

The Mean Well LRS-150-24 Switching Power Supply is priced at C$41.29, while the Lian Li Edge Series-850W Full Modular Power Supply retails for C$195.95. Both power supplies cater to different needs, with distinct differences in power output, efficiency, and design features. The Mean Well unit is designed primarily for lower power applications, while the Lian Li model supports high-end systems with substantial power requirements.

Design and Build Quality

The Mean Well LRS-150-24 is characterised by its miniature size and low-profile design, making it suitable for compact spaces. It features a selectable AC input range and can withstand a surge input of up to 300Vac for five seconds. On the other hand, the Lian Li Edge Series-850W boasts an L-Shape design tailored for dual chamber cases, ensuring optimal airflow and cooling. With a robust steel material construction, the Lian Li unit promises durability, especially under heavy load conditions, making it a better choice for high-performance builds.

Power Output and Efficiency

When it comes to power output, the Mean Well LRS-150-24 provides a maximum of 150W, which is adequate for basic applications like powering single-board computers or low-power devices. In contrast, the Lian Li Edge Series-850W offers a significantly higher output of 850W, making it suitable for high-end gaming rigs and workstations. Additionally, the Lian Li power supply boasts an 80 PLUS Platinum efficiency rating, ensuring that it operates more efficiently compared to the Mean Well unit, which does not specify an efficiency rating but is known for low power consumption.

Features and Connectivity

The Mean Well LRS-150-24 includes features such as low power consumption of less than 0.5W when not under load, supporting energy savings. However, it lacks modularity, which may limit cable management options. Conversely, the Lian Li Edge Series-850W is fully modular, allowing users to connect only the cables they need, enhancing cable management and airflow within the case. It also features a built-in USB expansion hub with four internal USB 2.0 headers, a significant advantage for users requiring multiple USB connections.

Cooling and Noise Levels

The Mean Well LRS-150-24 operates at a high temperature rating, capable of functioning up to 70 degrees Celsius, but does not include any active cooling features. This could lead to potential thermal issues under continuous high-load conditions. In comparison, the Lian Li Edge Series-850W is equipped with a 120mm FDB fan and offers a fanless mode, allowing for silent operation under low loads. This feature is particularly beneficial for users who prioritise a quiet computing environment, especially in gaming or media production setups.

Compatibility and Installation

The Mean Well LRS-150-24 is simple to install due to its straightforward design, making it ideal for DIYers and basic setups. However, its lack of modularity may present challenges for cable management in more complex systems. The Lian Li Edge Series-850W, while requiring more careful consideration regarding case dimensions (especially in non-dual chamber cases), provides extensive compatibility with modern components, including being PCIe 5.1 ready. This makes it a future-proof option for those looking to build high-performance systems.

Price Consideration

The Mean Well LRS-150-24 is priced at C$41.29, which makes it an economical choice for users with basic power needs. This low price point is attractive for budget-conscious consumers seeking reliable power solutions. In contrast, the Lian Li Edge Series-850W is significantly more expensive at C$195.95, reflecting its higher power output and advanced features. For those investing in high-performance builds or seeking efficiency, the cost may be justified, but it represents a substantial investment compared to the Mean Well unit.

Which should you buy?

Choosing between the Mean Well LRS-150-24 and the Lian Li Edge Series-850W depends largely on your specific power needs and system requirements. If you are looking for a cost-effective power supply for basic applications, the Mean Well unit is a solid choice. However, for users building high-performance systems who require substantial power output, modularity, and efficiency, the Lian Li Edge Series-850W is undoubtedly the better option. With its advanced features and higher efficiency rating, it provides long-term value for more demanding computing environments.
