Asus ROG Strix 1200W Platinum PSU vs CORSAIR RM650e

Overview of the Products

In this comparison, we will examine the Asus ROG Strix 1200W Platinum PSU and the Corsair RM650e, focusing on their performance, efficiency, and overall value. The Asus ROG Strix is priced at £179.99, while the Corsair RM650e is significantly more affordable at £79.99. This price difference sets the stage for a deeper evaluation of their features and capabilities.

Power Output and Efficiency

The Asus ROG Strix 1200W Platinum boasts a powerful 1200W output, making it an excellent choice for high-performance gaming rigs and demanding workloads. Its GaN MOSFET technology enhances power efficiency by up to 30%, providing a cooler operational environment. In contrast, the Corsair RM650e offers a 650W output, which is suitable for mid-range systems. While the RM650e is Intel ATX 3.1 Certified and supports the PCIe 5.1 platform, it cannot match the sheer power output of the Asus unit.

Cooling Technologies

Cooling is crucial for maintaining system stability and performance. The Asus ROG Strix is equipped with large ROG heatsinks that effectively manage temperatures, ensuring lower noise levels compared to reference designs. Its dual ball fan bearings extend the lifespan of the cooling fan, lasting up to twice as long as traditional sleeve bearing designs. Conversely, the Corsair RM650e features a 120mm artic bearing fan designed to keep noise to a minimum, even under full load. While both power supplies implement effective cooling mechanisms, the Asus offers a more robust solution for high-demand scenarios.

Modularity and Installation

Modularity simplifies installation and cable management, a strong point for the Corsair RM650e. Its fully modular design allows users to connect only the cables necessary for their specific configuration, reducing clutter and improving airflow. This feature is particularly advantageous for those building custom PCs. The Asus ROG Strix, while not explicitly stated as fully modular, does offer a well-organised internal layout that contributes to efficient cooling. However, it may not provide the same level of ease in cable management as the Corsair.

Noise Levels

Noise levels are an essential consideration for many users, particularly in quiet environments. The Asus ROG Strix features 0dB technology, which allows for virtually silent operation during light gaming sessions. This capability is appealing for gamers who prefer a quieter experience. Meanwhile, the Corsair RM650e utilises its specially calculated fan curve to maintain low noise levels even at full load. Despite the robust performance of both units, the Asus ROG Strix has the edge in silent operation during less demanding tasks.

Component Quality and Durability

Durability is an essential factor when selecting a power supply. The Asus ROG Strix utilises premium components, including GaN MOSFETs and large heatsinks, which contribute to its longevity and reliability. The dual ball fan bearings also enhance durability, making it a solid investment for long-term use. On the other hand, the Corsair RM650e features 105°C rated capacitors that ensure reliable electrical performance. With a seven-year warranty backing its durability, the RM650e also represents a dependable choice, albeit with potentially lower longevity when compared to the high-end components of the Asus.

Price and Value Proposition

The price difference between the two power supplies is significant, with the Asus ROG Strix retailing at £179.99 and the Corsair RM650e at £79.99. This disparity raises questions about value for money. The Asus ROG Strix offers advanced features and higher power output, making it a suitable option for enthusiasts and gamers requiring top-tier performance. Conversely, the Corsair RM650e presents a compelling choice for users on a budget or those with mid-range systems, providing essential features at a fraction of the cost.

Target Audience

The Asus ROG Strix is designed for gamers and PC builders who demand high power and efficiency, making it ideal for those with high-performance graphics cards and processors. Its advanced features are tailored to meet the needs of demanding users. In contrast, the Corsair RM650e is perfect for casual gamers and everyday users who need a reliable power supply without breaking the bank. Its certification and modular design cater to users who value efficiency and ease of installation.

Which should you buy?

Ultimately, choosing between the Asus ROG Strix 1200W Platinum PSU and the Corsair RM650e depends on your specific needs and budget. If you require a robust, high-performance power supply capable of handling demanding tasks, the Asus ROG Strix justifies its higher price with superior efficiency and features. However, if you are looking for a cost-effective, reliable power supply for a mid-range system, the Corsair RM650e offers excellent value with its modular design and quiet operation.
