ASUS ROG Strix 1200W Platinum vs CORSAIR CX550 80 Plus Bronze Non Modular Low-Noise ATX 550 Watt Power Supply - N

Price Comparison

When it comes to price, the CORSAIR CX550 is significantly more affordable than the ASUS ROG Strix 1200W Platinum. The ASUS ROG Strix is priced at C$329.99, whereas the CORSAIR CX550 is only C$84.99. This stark difference of C$245.00 makes the CORSAIR an attractive option for budget-conscious consumers or those looking to build a mid-range gaming system. While the ASUS offers high-end features, the price point may deter casual gamers or users who don’t require such robust specifications.

Power Output

Power output is a crucial factor in selecting a power supply, with the ASUS ROG Strix offering a substantial 1200 watts compared to the 550 watts of the CORSAIR CX550. This means the ASUS is better suited for high-performance gaming rigs, particularly those with multiple GPUs or power-hungry components. The CORSAIR, while adequate for many standard builds, may struggle under the load of more demanding hardware. The difference in power output can directly impact system stability and performance, especially during peak usage.

Efficiency Ratings

The efficiency ratings of the two power supplies highlight significant differences in energy consumption. The ASUS ROG Strix 1200W Platinum is 80 PLUS Platinum certified, meaning it can achieve up to 92% efficiency at typical loads. In contrast, the CORSAIR CX550 is 80 PLUS Bronze certified, with operational efficiency reaching up to 88%. Although both units offer good efficiency, the ASUS unit provides an extra 4% efficiency, which can lead to reduced energy costs and lower heat generation over time.

Noise Levels

Noise levels are another important aspect when choosing a power supply. The CORSAIR CX550 features a 120mm thermally controlled low-noise cooling fan that optimally adjusts its speed based on the load, ensuring quiet operation during lighter tasks. In contrast, the ASUS ROG Strix employs 0dB technology, allowing it to operate silently during light gaming and low loads. While both units emphasize quiet performance, the ASUS is specifically designed to maintain silence under minimal stress, making it a solid choice for users prioritizing a quiet computing environment.

Build Quality and Components

Build quality can significantly affect the longevity and reliability of a power supply. The ASUS ROG Strix boasts dual ball fan bearings that can last up to twice as long as standard sleeve bearing designs, ensuring durability over time. Additionally, it uses low-ESR capacitors and premium components, contributing to its high efficiency and stability. On the other hand, the CORSAIR CX550 also delivers a robust build, guaranteed to provide its full rated wattage, but lacks the same level of high-end components seen in the ASUS. This distinction may be crucial for users looking for a power supply that can withstand heavy use and last for years.

Warranty and Support

The warranty and support offerings for these power supplies are quite different. The ASUS ROG Strix comes with a generous 10-year warranty, reflecting confidence in its durability and performance. Meanwhile, the CORSAIR CX550 includes a three-year warranty, which is standard but significantly shorter than that of its competitor. This extended warranty from ASUS could provide peace of mind for gamers and professionals investing in a high-end build, knowing that they have long-term support should any issues arise.

Compatibility and Future-Proofing

In terms of compatibility, the ASUS ROG Strix is ATX 3.1 compatible and features a native 12V-2x6 connector, making it ready for next-gen graphics cards. This future-proofing aspect is particularly relevant as gaming technology continues to evolve. The CORSAIR CX550, while suitable for many standard builds, may not support the latest hardware as effectively. Users planning to upgrade their systems frequently should consider the ASUS for its advanced compatibility features and readiness for upcoming technology.

Which should you buy?

In summary, the choice between the ASUS ROG Strix 1200W Platinum and the CORSAIR CX550 80 Plus Bronze largely depends on your specific needs and budget. If you require high power output, superior efficiency, and advanced features for a high-performance gaming rig, the ASUS ROG Strix is the clear winner, despite its higher price tag of C$329.99. However, for users with more modest setups or those looking for an economical option, the CORSAIR CX550 at C$84.99 offers solid performance and good efficiency. Ultimately, assessing your power requirements and budget will guide your decision on which power supply to purchase.
