ASRock PRO 750G vs CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX 550 Watt Power Supply - N

Price Comparison

When it comes to pricing, the ASRock PRO 750G is slightly more expensive than the CORSAIR CX550. The ASRock PRO 750G is priced at C$89.94, while the CORSAIR CX550 is available for C$84.99. This C$5.00 difference may seem small, but it reflects the higher wattage and efficiency rating of the ASRock unit. The PRO 750G offers 750W of power compared to 550W for the CX550. Therefore, if your configuration requires more power, the price difference might be justified by the performance benefits of the ASRock unit.

Efficiency Ratings

Efficiency plays a crucial role in power supply performance. The ASRock PRO 750G boasts an 80 Plus Gold certification, which indicates it can achieve up to 90% energy efficiency. In contrast, the CORSAIR CX550 has an 80 Plus Bronze certification, providing up to 88% operational efficiency. This 2% difference translates into less energy waste and reduced operating costs with the ASRock power supply, making it a more economical choice in the long run for users looking to minimise energy expenses.

Power Capacity

The power capacity of a power supply is vital for ensuring stability in high-performance systems. The ASRock PRO 750G offers a robust 750W output, making it suitable for medium to high-performance configurations, especially those with demanding graphics cards. On the other hand, the CORSAIR CX550 provides a maximum of 550W. For users running more power-hungry components or planning to upgrade in the future, the ASRock’s higher capacity may provide the headroom needed for optimal performance.

Cooling Systems

Effective cooling is essential to maintain performance and longevity in power supplies. The ASRock PRO 750G features a 120mm silent cooling fan designed for low-noise operation while effectively managing heat. Similarly, the CORSAIR CX550 also includes a 120mm thermally controlled fan that spins faster under heavy loads and slows down during lighter use to ensure quiet operation. Both units prioritise noise reduction, but the ASRock’s design focuses on continuous silent operation, which may appeal to users seeking a quieter computing environment.

Compatibility

Compatibility with various components is crucial when selecting a power supply. The ASRock PRO 750G is ATX 3.1 and PCIe 5.1 compatible, ensuring it can support next-generation components and technologies. Additionally, it features a native 12V-2x6 jack that supports high-performance graphics cards with up to 450W. In contrast, while the CORSAIR CX550 is designed to fit most modern PC cases with its compact 125mm length, it does not specify compatibility with the latest ATX and PCIe standards. For users who plan on using cutting-edge hardware, the ASRock’s advanced compatibility may be a decisive factor.

Warranty and Support

Warranty and customer support can significantly impact a buyer's confidence in a power supply. Both the ASRock PRO 750G and the CORSAIR CX550 come with a three-year warranty, indicating a commitment to quality and reliability from both brands. However, the ASRock unit encourages users to contact them directly via Amazon for support, while CORSAIR offers global technical support, which may be more reassuring for users who prefer accessible customer service options.

Design and Aesthetics

The design of a power supply may influence buyer preference, especially for those concerned with the aesthetics of their build. The ASRock PRO 750G features a dual-color design that may stand out in a gaming rig, while its overall design aligns with modern aesthetics. On the other hand, the CORSAIR CX550 has black sleeved cables and a powder-coated casing that blend seamlessly into most PC builds. While both units offer appealing designs, the choice may ultimately depend on individual style preferences and the specific colour scheme of the user’s setup.

Which should you buy?

Choosing between the ASRock PRO 750G and the CORSAIR CX550 largely depends on your specific needs and system requirements. If you require higher power capacity and efficiency, the ASRock PRO 750G is the better choice, with 750W and an 80 Plus Gold certification, making it ideal for high-performance gaming or workstation setups. However, if you are looking for a more budget-friendly option that still offers reliable performance for lower-demand systems, the CORSAIR CX550 at C$84.99 is a solid choice. Ultimately, consider your current and future power needs, as well as your budget, to make the most informed decision.
