Price Comparison

When comparing the price of the MEAN WELL LRS-350-24 and the SAMA White 650W Power Supply, the MEAN WELL is significantly cheaper at $26.00, making it about 59% less expensive than the SAMA, which retails for $62.99. This price difference is substantial, especially for budget-conscious consumers looking for a reliable power supply. While both products serve different purposes, the cost is a critical factor for many buyers, highlighting the MEAN WELL as a more economical choice for those needing a straightforward power solution without advanced features.

Power Output

The SAMA White 650W Power Supply offers a maximum output power of 650 watts, providing significantly more power than the MEAN WELL LRS-350-24, which has a maximum output of 350 watts. This difference of 300 watts makes the SAMA a better option for high-performance setups, particularly for gaming rigs that require more power for the latest GPUs like the RTX 30/40 series. The MEAN WELL, while lower in power output, is still suitable for various industrial applications, showcasing its versatility despite being less powerful.

Efficiency Ratings

The SAMA White Power Supply boasts an impressive 80 PLUS Gold certification, achieving up to 91.15% efficiency at 50% load. This high efficiency reduces energy waste and heat output, enhancing overall system stability and component longevity. In contrast, the MEAN WELL LRS-350-24 does not have an efficiency rating mentioned, which may indicate lower energy efficiency. For users who prioritize energy savings and performance, the SAMA stands out as the superior choice due to its efficiency credentials.

Design and Modularity

The SAMA White Power Supply features a fully modular design that simplifies cable management, allowing users to connect only the necessary cables for their setup. This design not only improves airflow but also helps maintain a clean and organized build. The MEAN WELL LRS-350-24, however, does not emphasize modularity and utilizes a standard output setup. For builders who appreciate aesthetics and ease of installation, the SAMA clearly offers advantages with its streamlined design.

Cooling System

In terms of cooling, the SAMA White Power Supply is equipped with a 120mm ECO fan that operates quietly, with noise levels as low as 20dB-A. This is particularly beneficial for users who desire a quiet operation during heavy loads. The MEAN WELL LRS-350-24 includes a built-in cooling fan with ON-OFF control, but specific noise levels are not provided, making it less clear how it compares in quiet operation. For users sensitive to noise, the SAMA is likely the better option due to its focus on low-noise performance.

Durability and Warranty

The SAMA White Power Supply is built with premium Japanese capacitors and comes with a 5-year warranty, underscoring its reliability and long-term performance. The MEAN WELL LRS-350-24 also emphasizes durability with features such as a 300 VAC surge input withstand capability and a 3-year warranty. While both power supplies are designed for longevity, the SAMA’s longer warranty period may provide additional peace of mind for consumers looking for assurance in their purchase.

Applications and Use Cases

The MEAN WELL LRS-350-24 is tailored for industrial applications, making it ideal for automation machinery and electronic instruments. In contrast, the SAMA White Power Supply is designed for modern gaming rigs and workstations, supporting high-end components such as the RTX 30/40 series GPUs. Depending on the intended use, consumers will find that their choice aligns with the specific needs of their systems, whether for industrial setups or gaming.

Which should you buy?

Choosing between the MEAN WELL LRS-350-24 and the SAMA White 650W Power Supply ultimately depends on your specific requirements. If you're looking for a budget-friendly option for basic industrial applications, the MEAN WELL at $26.00 offers excellent value and reliability. However, for gamers or those needing a high-performance power supply, the SAMA at $62.99 provides more power, efficiency, and a modular design, making it a worthy investment. Assess your power needs and application to determine the best fit for your setup.
