Asus ROG Strix 1200W Platinum PSU vs Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply - ATX 3.1 & PCIe

Introduction to Power Supplies

When it comes to building or upgrading a PC, selecting the right power supply unit (PSU) is crucial for ensuring stable performance. In this comparison, we will evaluate the Asus ROG Strix 1200W Platinum PSU and the Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply. Both units aim to deliver high efficiency and reliability, but they do so with different features and specifications that may appeal to various users.

Pricing Comparison

The Asus ROG Strix 1200W Platinum PSU is priced at £179.99, making it one of the higher-end options in the market. In contrast, the Corsair HX1000i is slightly more affordable at £169.99. While the price difference of £10 may seem minor, it is worth considering the performance and features each unit offers for that price. Users on a budget might find the Corsair model more appealing, particularly if they are looking for high-quality performance without a significant investment.

Efficiency and Performance

The Asus ROG Strix 1200W Platinum PSU boasts GaN MOSFET technology, which enhances power efficiency by up to 30%. This remarkable efficiency can lead to reduced energy costs and improved system stability. On the other hand, the Corsair HX1000i is Intel ATX 3.1 certified, ensuring compliance with modern power standards and the ability to handle transient power spikes. While both units prioritise efficiency, the Asus model offers a notable advantage in terms of energy savings, making it a strong contender for those focused on performance.

Cooling Solutions

Cooling is a vital aspect of PSU performance, and both units employ advanced fan technologies. The Asus ROG Strix features large heatsinks designed to maintain lower temperatures and noise levels than standard designs. It also includes dual ball fan bearings that can last up to twice as long as traditional sleeve bearings. The Corsair HX1000i, however, utilises a 140mm Fluid Dynamic Bearing fan that promises extremely quiet operation. Additionally, its Zero RPM Fan Mode allows the fan to switch off entirely under low and medium loads for near-silent performance. While both models excel in cooling, the Asus PSU may offer a slight edge in longevity and temperature management.

Modularity

Modularity is an important consideration for builders seeking tidy installations. The Corsair HX1000i is fully modular, allowing users to connect only the cables they need, which simplifies cable management and enhances airflow within the case. In contrast, the Asus ROG Strix does not specify its modularity in the provided features, which may imply a less flexible installation process. For users prioritising a clean and organised build, the Corsair model's fully modular design is a significant advantage.

Noise Levels

When it comes to noise levels, both power supplies are designed with quiet operation in mind. The Asus ROG Strix features 0dB technology, enabling silent operation during light gaming sessions. Meanwhile, the Corsair HX1000i's 140mm fan is designed for ultra-low noise and can also operate in a Zero RPM mode during low loads for complete silence. While both units aim to reduce noise, the specific technologies employed may appeal to different users, with the Asus model offering silent gaming capabilities and the Corsair focusing on fan control through software.

Software Integration

The Corsair HX1000i comes equipped with powerful iCUE software, allowing users to create custom fan curves and monitor power settings in real-time. This software also provides the ability to toggle between single and multi-rail overcurrent protection, which can enhance safety and performance. The Asus ROG Strix, however, does not mention any software integration. For tech-savvy users or those who appreciate detailed monitoring and control of their system, the Corsair's software capabilities are a noteworthy feature that adds value to its offering.

Brand Reputation

Both ASUS and Corsair are well-respected brands within the PC hardware industry, known for their quality and innovation. ASUS's ROG (Republic of Gamers) line is particularly esteemed among gamers and PC enthusiasts for its high performance and reliability. Corsair, on the other hand, is renowned for its extensive range of components and peripherals, including power supplies. Choosing between these brands often comes down to personal preference and past experiences, but both units are backed by solid reputations.

Which should you buy?

Ultimately, the choice between the Asus ROG Strix 1200W Platinum PSU and the Corsair HX1000i Fully Modular Ultra-Low Noise ATX Power Supply depends on your specific needs and preferences. If you prioritise efficiency, cooling performance, and gaming capabilities, the Asus model may be the better option for you. However, if modularity, software integration, and a slightly lower price are more important, the Corsair HX1000i stands out as an excellent choice. Both power supplies offer exceptional performance, so your decision will hinge on which features align best with your build and usage scenario.
