CORSAIR HX1500i vs Asus ROG Strix 1200W Platinum PSU

Price Comparison

When evaluating power supplies, price can often be a decisive factor. The CORSAIR HX1500i is priced at £229.00, while the Asus ROG Strix 1200W Platinum PSU comes in at a more budget-friendly £179.99. This presents a clear £49.01 difference, making the Asus option significantly cheaper. For users seeking high performance without a hefty price tag, the Asus unit offers a compelling alternative, positioning itself as a value-for-money choice in the premium power supply market.

Power Efficiency

Power efficiency is a critical consideration for any power supply, especially for gamers and high-performance PC builders. The Asus ROG Strix 1200W Platinum PSU boasts GaN MOSFET technology, which enhances power efficiency by up to 30%. This innovation not only improves performance but also contributes to a cooler internal layout, which can extend the lifespan of the unit. On the other hand, the CORSAIR HX1500i, while also efficient, does not specify a comparable efficiency enhancement. Users prioritising energy efficiency may find the Asus PSU to be the superior option.

Cooling Solutions

Effective cooling is essential for maintaining optimal performance in power supplies. The CORSAIR HX1500i features a 140mm Fluid Dynamic Bearing fan, designed for quiet operation and longevity. Moreover, its Zero RPM Fan Mode ensures that the fan remains off at low and medium loads, contributing to a near-silent user experience. In contrast, the Asus ROG Strix 1200W Platinum PSU employs large ROG heatsinks and dual ball fan bearings, which are noted to last up to twice as long as traditional sleeve bearings. This results in lower temperatures and noise levels. Both options offer advanced cooling features, but the CORSAIR model may provide a quieter operation under certain conditions.

Modular Design

The modular design of a power supply can greatly influence the ease of installation and cable management. The CORSAIR HX1500i is fully modular, allowing users to connect only the cables necessary for their specific system. This feature facilitates cleaner builds and reduces clutter. Similarly, the Asus ROG Strix 1200W Platinum PSU also supports an organised internal layout, attributed to its advanced GaN technology. While both models offer modular designs, the CORSAIR’s fully modular approach can be particularly appealing for users who prioritise a tidy build.

Performance Features

Performance features can significantly enhance the functionality of a power supply. The CORSAIR HX1500i supports Intel's ATX 3.1 standard, which is essential for compatibility with the latest PCIe Gen 5 platforms and offers resilience against transient power spikes. Additionally, its powerful iCUE software allows for custom fan curves and on-the-fly adjustments between single and multi-rail overcurrent protection. In contrast, the Asus ROG Strix 1200W Platinum PSU features a unique "GPU-FIRST" voltage sensing technology that can improve voltage delivery to graphics cards by up to 45%. This enhancement can lead to smoother gameplay and better overall performance. Both units have strong performance features, but the specific benefits may appeal to different user priorities.

Longevity and Durability

The longevity and durability of a power supply are paramount for long-term investments. The CORSAIR HX1500i is built with a focus on quiet operation through its high-quality fan, while the Asus ROG Strix 1200W Platinum PSU incorporates dual ball fan bearings, which are designed to last up to twice as long as standard bearings. This can be a significant consideration for users aiming for a stable and reliable power supply over time. Both brands are respected for their reliability, but the Asus unit’s construction may offer a slight advantage in terms of durability.

Brand Reputation

Brand reputation can play a crucial role in the decision-making process for power supplies. Corsair is widely known for its premium components and has a strong following within the gaming community. The CORSAIR HX1500i, with its advanced features and robust performance, aligns well with this reputation. Meanwhile, ASUS has established itself as a leader in gaming hardware, and the Asus ROG Strix 1200W Platinum PSU fits within their well-regarded ROG (Republic of Gamers) line. Both brands offer quality products, but user loyalty and brand perception can influence purchasing decisions.

Which should you buy?

Deciding between the CORSAIR HX1500i and the Asus ROG Strix 1200W Platinum PSU ultimately depends on individual needs and preferences. If budget is a primary concern, the Asus model at £179.99 presents a more economical option with innovative features like GaN MOSFET technology for enhanced efficiency. However, for those who prioritise modular design, advanced software integration, and the assurance of Intel ATX 3.1 certification, the CORSAIR HX1500i may justify its higher price of £229.00. Both power supplies offer excellent performance, but understanding your specific requirements will help determine the right choice for your build.
