Price Comparison

The CORSAIR HX1500i is significantly more expensive than the GameMax 800W Rampage Power Supply, priced at £229.00 compared to £45.94. This substantial price difference reflects the varying target markets and specifications of these two power supplies. The GameMax model is aimed at budget-conscious consumers or those building entry-level systems, while the CORSAIR unit targets high-performance builds with its advanced features. The cost of the HX1500i is over five times that of the GameMax, making it crucial for buyers to consider their needs and budget when choosing between the two.

Power Output

The CORSAIR HX1500i boasts an impressive 1500W capacity, making it suitable for high-end gaming rigs and demanding setups. In contrast, the GameMax 800W Rampage offers a maximum output of 800W, which is adequate for most standard gaming and basic systems. This difference in wattage indicates that the CORSAIR model can support more power-hungry components, such as multi-GPU configurations or high-performance CPUs. For users looking for extreme power and future-proofing, the HX1500i is the clear choice, while the GameMax model is more suited for moderate power needs.

Efficiency Ratings

The GameMax 800W Rampage features an 80 Plus Bronze certification, ensuring an efficiency of up to 88% at a 50% load. This certification indicates that the Rampage is designed to save energy and reduce electricity costs, making it a sensible choice for budget-oriented users. The CORSAIR HX1500i, while not explicitly mentioned, is Intel ATX 3.1 certified, suggesting it meets high standards for efficiency and performance. Both power supplies aim to provide reliable performance, but the GameMax's efficiency rating gives it an edge in energy savings for everyday use.

Build Quality and Components

The CORSAIR HX1500i is equipped with premium components, including a 140mm Fluid Dynamic Bearing (FDB) fan that offers quiet operation and longevity. This indicates a focus on durability and performance, appealing to users who prioritise high-quality parts. On the other hand, the GameMax 800W Rampage utilises Japanese TK main capacitors, which are known for their reliability and life expectancy. While both power supplies are constructed with quality materials, the CORSAIR model may provide a more robust performance in demanding environments due to its advanced cooling solution.

Cooling Solutions

The cooling solutions differ significantly between these two power supplies. The CORSAIR HX1500i features a Zero RPM Fan Mode, which allows the fan to switch off entirely at low and medium loads, resulting in near-silent operation. This feature is ideal for users seeking a quiet computing experience. In comparison, the GameMax Rampage is equipped with a 14cm cooling fan designed for silent and effective cooling. While both units aim to manage heat efficiently, the advanced fan control of the HX1500i provides an added benefit for users in noise-sensitive environments.

Modular Design

The CORSAIR HX1500i offers fully modular cabling, enabling users to connect only the cables necessary for their build. This helps keep cable management tidy and improves airflow within the case. Conversely, the GameMax 800W Rampage is a non-modular power supply, which means all cables are permanently attached. Although this may simplify installation for some users, it can lead to cluttered builds and potentially obstruct airflow. The modular design of the HX1500i offers a significant advantage for those who prioritise aesthetics and airflow in their PC builds.

Software Integration

One of the standout features of the CORSAIR HX1500i is its compatibility with powerful CORSAIR iCUE software. This allows users to create custom fan curves, monitor power settings, and toggle between single to multi-rail overcurrent protection (OCP) on-the-fly. This level of control and monitoring is absent in the GameMax 800W Rampage, which does not include any software integration. For tech enthusiasts or gamers who appreciate granular control over their system, the HX1500i’s software capabilities provide a considerable advantage.

Which should you buy?

Choosing between the CORSAIR HX1500i and the GameMax 800W Rampage Power Supply ultimately depends on your specific needs and budget. If you’re building a high-performance gaming rig that demands exceptional power, efficiency, and features, the HX1500i is the superior choice at £229.00. However, for those with a tighter budget or less demanding power requirements, the GameMax 800W Rampage at £45.94 offers solid performance and reliability for basic systems. Consider your power needs, system requirements, and budget constraints carefully before making a decision.
