The MEAN WELL LRS-100-24 is priced at C$32.95, offering a compact design suitable for industrial applications, while the CORSAIR CX750M is a more powerful unit retailing at C$124.99, designed primarily for gaming and high-performance PCs.

Design and Build Quality

The MEAN WELL LRS-100-24 features a slim 30mm profile and a metal mesh housing, which ensures excellent heat dissipation, allowing for fanless operation. This rugged design is suited for harsh environments and can operate at high altitudes up to 5,000 meters. In contrast, the CORSAIR CX750M boasts a semi-modular design, where the main power cables are attached, and the rest are modular, allowing users to customise their setup. This design simplifies cable management, making it an appealing choice for gamers looking to optimise airflow within their systems.

Power Output and Efficiency

The MEAN WELL LRS-100-24 provides a stable output of 24V at 4.5A, delivering a maximum of 108W of power. It boasts an impressive energy efficiency rating of 90%, minimising power loss during operation. On the other hand, the CORSAIR CX750M offers a significantly higher power output of 750W, making it capable of supporting high-end graphics cards, including the latest Nvidia RTX 50-series and older 40-series models. This makes it ideal for users who require substantial power for demanding applications or gaming setups.

Application Suitability

The MEAN WELL LRS-100-24 is designed specifically for industrial and commercial applications, such as control panels and electronic instruments. Its ability to withstand a surge input of 300VAC for up to five seconds without damage further emphasises its industrial focus. Conversely, the CORSAIR CX750M is tailored for gaming and performance PCs, providing ample power for modern GPUs. Users looking to build or upgrade a gaming rig will find the CX750M’s power delivery capabilities particularly advantageous.

Protection Features

In terms of safety, the MEAN WELL LRS-100-24 includes multiple protection features such as overvoltage protection, overload protection, and short circuit protection. It is safety-certified to CE, IEC/EN 62368-1, and EN 61558 standards, ensuring reliable operation even in challenging conditions. The CORSAIR CX750M, while not detailed in its product description, also adheres to modern safety standards for power supplies, including ATX 3.1 and PCIe 5.1 specifications, ensuring safe and reliable power delivery.

Noise Levels

The MEAN WELL LRS-100-24 operates fanless, which means it produces no noise, making it an excellent choice for environments where silence is paramount, such as laboratories or studios. The CORSAIR CX750M, equipped with a 120mm low-noise fan, operates quietly under low and medium loads. However, it may produce some noise under heavy load conditions. For users prioritising silent performance, the MEAN WELL LRS-100-24 has a distinct advantage.

Price Comparison

The MEAN WELL LRS-100-24 is priced at C$32.95, making it an affordable option for those who need a reliable power supply for industrial use. In contrast, the CORSAIR CX750M is significantly more expensive at C$124.99. While the higher price reflects its increased power output and gaming capabilities, it may be considered overkill for users with simpler power needs.
