CORSAIR RM750e vs GameMax 800W Rampage Power Supply

Price Comparison

The CORSAIR RM750e is priced at £81.99, while the GameMax 800W Rampage Power Supply is significantly cheaper at £45.94. This difference of £36.05 makes the GameMax a more budget-friendly option, appealing to those who are looking for a cost-effective power supply without compromising too much on performance. However, the higher price of the RM750e reflects its advanced features and reliability, which may justify the investment for serious gamers or users with high-performance components. In essence, the choice between these two products largely depends on your budget and the importance of premium features in your build.

Efficiency Ratings

When it comes to efficiency, the GameMax 800W Rampage Power Supply boasts an 80 Plus Bronze certification, achieving an efficiency of up to 88% at a load of 50%. This ensures that users can expect reliable power delivery and reduced energy waste during operation. On the other hand, the CORSAIR RM750e is compliant with the modern ATX 3.1 standard, which supports PCIe 5.1 and ensures improved power efficiency, particularly during high-load scenarios. While both power supplies offer decent efficiency, the RM750e's certification aligns with the latest standards, potentially offering better performance for demanding systems.

Build Quality

The build quality of the CORSAIR RM750e is underscored by its use of 105°C-rated capacitors, which enhance its reliability and electrical performance. In contrast, the GameMax 800W Rampage features a Japanese TK main capacitor, which is also known for its durability and quality assurance. Both power supplies utilise high-quality components; however, the RM750e explicitly highlights its capability to deliver steady power under various conditions. This might make it a more appealing choice for users who prioritise long-term reliability in high-performance builds.

Cooling Solutions

Cooling capabilities are an essential aspect of power supply performance. The CORSAIR RM750e is equipped with a 120mm rifle bearing fan designed to maintain low noise levels, even under full load. This feature is crucial for users who prefer a quiet computing environment. Meanwhile, the GameMax 800W Rampage utilises a larger 14cm cooling fan, which promises ultra-silent operation while delivering effective cooling. While both products aim for low noise, the choice may come down to personal preference regarding fan size and noise levels during operation.

Modular Design

One of the key features of the CORSAIR RM750e is its fully modular design, allowing users to connect only the cables that their system requires. This not only simplifies installation but also enhances cable management and airflow within the PC case. In contrast, the GameMax 800W Rampage is a non-modular design, which means all cables are fixed and cannot be removed. This could lead to excess cables cluttering the build, making the RM750e a more appealing option for those who value neatness and optimal airflow in their setups.

Performance Under Load

The performance of a power supply under load is critical for gamers and high-performance PC users. The CORSAIR RM750e is designed to withstand transient power excursions from the GPU, thanks to its compliance with the ATX 3.1 standard. This feature is particularly beneficial during intense gaming sessions or heavy computational tasks. The GameMax 800W Rampage, with its single 12V rail, also offers high compatibility and can handle extreme current output, making it suitable for gaming rigs. While both supplies can perform well, the RM750e may provide an edge in high-demand scenarios due to its advanced design.

Aesthetics and Cable Management

Aesthetically, the GameMax 800W Rampage features flat black cables that enhance the overall look of the PC build while improving cable management. This design can help save space and promote better airflow within the case. On the other hand, the CORSAIR RM750e's fully modular design not only aids in aesthetics but also allows builders to eliminate unnecessary cables completely, resulting in a cleaner build. If visual appeal and neatness are priorities for your build, the RM750e may have a slight advantage, although the Rampage also caters to those who appreciate a tidy setup.

Which should you buy?

Choosing between the CORSAIR RM750e and the GameMax 800W Rampage Power Supply ultimately depends on your specific needs and budget. The RM750e, at £81.99, offers advanced features such as full modularity, high efficiency, and superior cooling capabilities, making it ideal for high-performance systems. Conversely, the GameMax 800W Rampage, priced at £45.94, provides solid performance for budget-conscious users, particularly those who are building basic systems or gaming rigs without demanding power requirements. If you prioritise reliability and modern features, the RM750e is the clear choice; however, for those seeking a cost-effective solution without needing the latest advancements, the GameMax is a commendable option.
