CORSAIR SF850 vs GameMax 800W Rampage Power Supply

Price Comparison

The CORSAIR SF850 is significantly more expensive than the GameMax 800W Rampage Power Supply. Priced at £149.99, the CORSAIR SF850 is positioned as a premium offering in the power supply market. In contrast, the GameMax 800W Rampage is available at a much more accessible price of £45.94. This price difference of £104.05 reflects the varying target audiences and performance expectations of these products. While the CORSAIR model may appeal to high-end users looking for top-notch efficiency and features, the GameMax option provides a budget-friendly choice for those who need reliable power without the frills.

Efficiency Ratings

Efficiency ratings are crucial when considering a power supply, and here the two products differ significantly. The CORSAIR SF850 boasts an impressive 80 PLUS Platinum rating, which indicates it achieves high efficiency levels, particularly under load. This rating means that the SF850 maintains efficiency levels above 90% at 50% load, making it an excellent choice for energy-conscious users. In comparison, the GameMax 800W Rampage holds an 80 PLUS Bronze certification, achieving an efficiency of up to 88% at a similar load. While the GameMax offers decent efficiency, the CORSAIR model is more suited for users prioritising energy efficiency and long-term savings on electricity bills.

Form Factor and Compatibility

The form factor and compatibility of these power supplies highlight their intended use cases. The CORSAIR SF850 is designed in a compact SFX form-factor, making it ideal for small-form-factor PCs or for users aiming to save space in larger cases. This is particularly advantageous for builders focusing on aesthetics and efficient use of space. Conversely, the GameMax 800W Rampage is a standard ATX power supply, which provides high compatibility with a broader range of cases. While the GameMax's larger size may limit its placement options, it is a solid choice for traditional builds where space constraints are not a priority.

Cooling Solutions

Cooling performance is a vital aspect of any power supply, and both products incorporate effective cooling mechanisms. The CORSAIR SF850 features a 92mm PWM cooling fan, which is designed for low-noise operation while delivering powerful cooling performance. This is particularly beneficial for high-performance systems where heat generation can be a concern. On the other hand, the GameMax 800W Rampage utilises a larger 14cm cooling fan that promises ultra-silent operation alongside effective cooling. While both fans aim to minimise noise, the larger fan of the GameMax may provide better airflow, making it a suitable option for users who prefer quieter systems during intensive tasks.

Cable Management

Effective cable management can enhance the build quality and airflow of a PC. The CORSAIR SF850 features fully modular Type-5 Micro-Fit PSU connectors, allowing users to connect only the cables they need. This modularity not only simplifies installation but also contributes to a tidier case, particularly in compact builds. In contrast, the GameMax 800W Rampage utilises flat black cables, which are designed to improve aesthetics and ease of management. While the GameMax does not offer modular cabling, the flat design helps in maintaining clean cable routing, making it easier to optimise airflow in the case.

Build Quality and Components

Build quality is an essential consideration when selecting a power supply, and here the CORSAIR SF850 stands out with its use of 105°C rated Japanese capacitors, which are known for their reliability and longevity. This high-quality construction aids in delivering stable power and enhances the durability of the unit. The GameMax 800W Rampage also incorporates a Japanese TK main capacitor, providing a reliable life expectancy and quality assurance. However, the premium components in the CORSAIR SF850 suggest a longer lifespan and better performance under demanding conditions, making it a more robust option for high-performance gaming rigs.

Target Audience

The target audiences for these power supplies are markedly different. The CORSAIR SF850 is clearly aimed at enthusiasts and gamers who demand the best performance, efficiency, and build quality. Its premium features, such as the 80 PLUS Platinum rating and compact form factor, cater to users who are likely to invest significantly in their systems. Conversely, the GameMax 800W Rampage is designed for budget-conscious users or those building entry-level to mid-range systems. Its lower price point and adequate performance make it an appealing choice for first-time builders or casual gamers who need reliable power without breaking the bank.

Which should you buy?

Ultimately, the decision between the CORSAIR SF850 and the GameMax 800W Rampage Power Supply hinges on your specific needs and budget. If you are seeking superior efficiency, compact design, and high build quality, the CORSAIR SF850 is the clear choice, albeit at a higher price of £149.99. However, if you are looking for a cost-effective solution that offers decent performance for everyday use, the GameMax 800W Rampage at £45.94 could be the better option. Consider your usage scenario and priorities to make the best choice for your build.
