CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX 550 Watt Power Supply - N vs ESGAMING 650W Non Modular Power Supply with Low-Noise 120mm Fan ATX PSU

Price Comparison

When it comes to price, the ESGAMING 650W Non Modular Power Supply offers a significant advantage at C$55.99, making it a budget-friendly choice compared to the CORSAIR CX550, which retails for C$84.99. This price difference of C$29.00 is notable, especially for consumers on a tight budget. While the CORSAIR brand is well-known for its quality, the ESGAMING model presents a more economical option, appealing to those who may not require the additional features associated with higher-priced products.

Power Output

The power output is a crucial factor when choosing a power supply, and here the ESGAMING 650W leads with a higher wattage capacity of 650 watts, compared to the CORSAIR CX550's 550 watts. This 100-watt difference can provide better support for high-performance components, especially in gaming or intensive workloads. While both power supplies are designed to deliver continuous power, the additional wattage of the ESGAMING unit allows for more flexibility in hardware configurations, making it a compelling option for those looking to future-proof their systems.

Efficiency Ratings

Efficiency ratings are essential for reducing energy costs and heat generation. The CORSAIR CX550 boasts an 80 PLUS Bronze certification, which indicates it can provide up to 88% operational efficiency. This means it generates less heat and lowers energy costs during operation. On the other hand, the ESGAMING 650W does not specify an efficiency rating, which could imply less assurance in energy performance. For users concerned about energy efficiency and long-term costs, the CORSAIR's certification is a notable advantage.

Noise Levels

Noise levels can significantly affect the overall user experience, particularly in quiet environments. The CORSAIR CX550 features a low-noise cooling fan that operates with minimal sound, spinning faster only under heavy loads. This design ensures quieter operation during lighter usage. Meanwhile, the ESGAMING 650W also includes a 120mm fan designed for virtually silent operation at low loads. While both power supplies aim for low noise, the specific thermally controlled feature of the CORSAIR may provide an edge for users prioritising a silent computing experience.

Build Quality and Design

Build quality often correlates with longevity and reliability. The CORSAIR CX550's compact 125mm casing is designed to fit easily in modern PC cases, and its black sleeved cables contribute to a clean aesthetic. The ESGAMING 650W features a standard ATX form factor, measuring 16015086mm, which is compatible with various setups. However, the lack of detailed information on the materials used in the ESGAMING unit raises questions about its overall durability. In terms of design, the CORSAIR's black powder-coated casing may appeal more to users looking for a sleek, professional appearance in their builds.

Cooling Solutions

Effective cooling is critical for maintaining system performance and longevity. The CORSAIR CX550 is equipped with a 120mm thermally controlled fan that adjusts its speed based on the system's temperature, providing efficient cooling while minimising noise. The ESGAMING 650W also includes a 120mm fan and is designed for virtually silent operation at low loads. While both power supplies feature cooling solutions aimed at maintaining quiet operation, the adaptive cooling capability of the CORSAIR could offer better thermal management under varying loads, which is advantageous for high-performance systems.

Safety Features

Safety features are paramount in power supply units to protect sensitive components. The ESGAMING 650W includes a comprehensive protection system with features like Over Voltage Protection (OVP), Under Voltage Protection (UVP), and more. This ensures maximum safety for the connected components. In contrast, the CORSAIR CX550 does not explicitly list its safety features, though it is backed by a three-year warranty, indicating confidence in its reliability. Users prioritising safety may find the ESGAMING's extensive protections to be reassuring, particularly for high-stakes builds.

Which should you buy?

Choosing between the CORSAIR CX550 and the ESGAMING 650W ultimately depends on your specific needs and budget. If you are looking for an affordable option with higher power output, the ESGAMING 650W at C$55.99 is an excellent choice. However, if energy efficiency, quieter operation, and brand reliability are priorities for you, the CORSAIR CX550 at C$84.99 offers compelling advantages with its 80 PLUS Bronze certification and low-noise cooling feature. Each power supply has its strengths, making it essential to align your choice with your personal requirements and system demands.
