Mean Well EDR-120-24 Single Output DIN Rail Power Supply 24V 5 Amp 120W vs Lian Li Edge Series-850W Full Modular Power Supply-80 Plus Platinum-ATX 3.0

Overview

In this comparison, we will explore two distinct power supplies: the Mean Well EDR-120-24 Single Output DIN Rail Power Supply and the Lian Li Edge Series-850W Full Modular Power Supply. While both products serve the purpose of delivering electrical power, they cater to different needs and applications. The Mean Well power supply is priced at C$42.99 and offers 120 watts of power output, whereas the Lian Li model is a more powerful option at C$195.95, providing up to 850 watts.

Design and Build Quality

The design of the Mean Well EDR-120-24 is straightforward, tailored for DIN rail installation, which is ideal for industrial applications. It is compact and efficient, with a focus on delivering reliable power. In contrast, the Lian Li Edge Series features an L-shaped design, optimized for dual chamber cases, ensuring better airflow and aesthetics in a custom PC build. This design consideration is crucial for users aiming for a clean and efficient internal layout in their setups.

Power Output and Efficiency

The Mean Well EDR-120-24 provides a primary output voltage of 24V and a maximum output power of 120 watts. This makes it suitable for smaller applications or devices that require consistent and reliable power without the need for extensive wattage. On the other hand, the Lian Li Edge Series boasts an impressive output of 850 watts with 80 PLUS Platinum efficiency. This high efficiency translates to less wasted energy and lower electricity bills, making it a better option for demanding systems that require substantial power for multiple components.

Features and Functionality

The Mean Well EDR-120-24 is a functional power supply that delivers 5 amps of output current, making it reliable for specific applications that do not require high power levels. However, it lacks advanced features that modern power supplies boast. In contrast, the Lian Li Edge Series comes equipped with a built-in USB expansion hub, offering four internal USB 2.0 headers. This feature is particularly beneficial for users needing additional connectivity options. Additionally, Lian Li’s model is PCIe 5.1 ready, which ensures future compatibility with the latest graphics cards and components.

Compatibility and Installation

The Mean Well EDR-120-24 is designed for straightforward installation on a DIN rail, making it an excellent choice for industrial or commercial environments. Its simple setup process allows for easy integration into existing systems. Conversely, the Lian Li Edge Series is designed with specific case compatibility in mind, particularly for dual chamber cases. Users with non-dual chamber cases must ensure their case height does not exceed 400mm for proper installation. This specificity can be a limitation for some users who might not have the optimal case setup.

Cooling and Noise Levels

Cooling is a crucial factor in power supply performance. The Mean Well EDR-120-24 does not provide detailed information on its cooling system; however, it is generally designed for stable operation under normal conditions. In contrast, the Lian Li Edge Series features a 120mm FDB fan and also offers a fanless mode. This allows the power supply to operate silently during low load conditions, making it an attractive option for users seeking a quiet computing environment. The advanced cooling design ensures that the Lian Li can handle high loads without excessive noise.

Price and Value

The Mean Well EDR-120-24 is priced at C$42.99, making it an economical choice for users who require a reliable power supply for lower power applications. In contrast, the Lian Li Edge Series is priced at C$195.95, reflecting its advanced features, higher wattage, and efficiency rating. While the Lian Li may seem significantly more expensive, its capabilities justify the price for users who need a robust power supply for high-performance systems.

Which should you buy?

When deciding between the Mean Well EDR-120-24 and the Lian Li Edge Series, it ultimately comes down to your specific needs. If you require a low-cost, reliable power supply for basic applications, the Mean Well EDR-120-24 is an excellent choice. However, for users building high-performance systems that demand more power and efficiency, the Lian Li Edge Series is the superior option. Its advanced features, higher output, and enhanced cooling capabilities make it well worth the investment for those who need the best performance from their power supply.
