Price Comparison

When comparing the prices of the 90W 65W Power Supply and the CORSAIR CX550, the difference is significant. The 90W 65W Power Supply is priced at $16.99, making it approximately 74% cheaper than the CORSAIR CX550, which is available for $65.99. This stark contrast in pricing positions the NATNO power supply as an attractive option for budget-conscious consumers, particularly those using compatible HP models. However, the price is just one aspect to consider; the features and performance also play vital roles in determining the best choice for your needs.

Compatibility

The 90W 65W Power Supply stands out for its extensive compatibility with various HP products. It is designed to work seamlessly with models like the HP ProDesk 600 G1 through G6, EliteDesk 800, and Omni All-in-One series, among others. In contrast, the CORSAIR CX550 is a more universal power supply option, catering to a wide range of PC builds but lacking the specific compatibility with HP devices. If you own an HP system, the NATNO power supply is the clear winner in this category, as it ensures you have a reliable power source tailored for your hardware.

Power Efficiency

The CORSAIR CX550 offers 80 PLUS Bronze certification, signifying operational efficiency of up to 88%. This means that it generates less heat and reduces energy costs over time, making it an excellent choice for users looking to save on electricity bills. The 90W 65W Power Supply does not specify its efficiency ratings, which is a notable omission. For users prioritizing energy efficiency and long-term savings, the CORSAIR CX550 is the superior option, demonstrating that sometimes investing in quality can lead to greater overall savings.

Performance

In terms of performance, the CORSAIR CX550 guarantees full continuous power delivery at 550 watts, ensuring stable operation even under heavy loads. This is particularly beneficial for gamers or users with high-performance PCs. Conversely, the 90W 65W Power Supply provides 90 watts of output, sufficient for low to moderate usage scenarios typical of HP Mini desktops. If your computing needs lean towards demanding applications, the CORSAIR CX550 is a more reliable choice, delivering the power required for performance-intensive tasks.

Noise Levels

The CORSAIR CX550 features a 120mm thermally controlled low-noise cooling fan, which minimizes noise during operation. This fan only ramps up when the power supply is under considerable stress, resulting in quieter performance during regular use. The 90W 65W Power Supply does not mention any noise control features, which could lead to a noisier experience during operation. For users who prioritize a quiet computing environment, the CORSAIR CX550 is the better option with its noise-reduction technology.

Build Quality and Design

In terms of build quality, the CORSAIR CX550 boasts a compact casing of 125mm, designed to fit easily in most modern PC cases, while also featuring black sleeving and a powder-coated casing that complements various builds. The aesthetic and functional design is appealing to many users. The 90W 65W Power Supply, however, does not provide any information about its design or build quality, leaving its aesthetics and fit in question. For those who value a sleek design and compatibility with their PC case, the CORSAIR CX550 is likely to be more satisfying.

Warranty and Support

The CORSAIR CX550 comes with a three-year warranty, providing peace of mind for users regarding reliability and support. Additionally, customers benefit from the backing of CORSAIR's global technical team, which can assist in troubleshooting and ensuring dependable power. The 90W 65W Power Supply does not specify any warranty information, which could be a concern for potential buyers. Therefore, the warranty and support offered by the CORSAIR CX550 are crucial factors that enhance its overall value proposition.

Which should you buy?

Choosing between the 90W 65W Power Supply and the CORSAIR CX550 ultimately depends on your specific needs and system requirements. If you are seeking a budget-friendly power supply for an HP Mini desktop, the 90W 65W Power Supply at $16.99 is an excellent choice due to its compatibility with various HP models. However, if you need a more robust power supply for high-performance computing with a focus on efficiency, noise control, and support, the CORSAIR CX550 at $65.99 is worth the investment. Consider your priorities—whether it's cost, compatibility, or performance—when making your decision.
