CORSAIR SF850 vs Asus ROG Strix 1200W Platinum PSU

Overview of the CORSAIR SF850 and Asus ROG Strix 1200W Platinum PSU

The CORSAIR SF850 and Asus ROG Strix 1200W Platinum PSU offer distinct advantages in the power supply market. The CORSAIR SF850 is priced at £149.99, while the Asus ROG Strix 1200W Platinum PSU comes in at £179.99. While both power supplies bear the prestigious 80 PLUS Platinum rating, they cater to different user needs and system configurations.

The SF850 is particularly well-suited for small-form-factor PCs due to its compact SFX design, making it ideal for gamers looking to optimise space. In contrast, the ROG Strix 1200W, with its higher wattage, targets users requiring more power for extensive gaming rigs or workstations. Understanding these differences will help you decide which power supply aligns best with your requirements.

Design and Form Factor

The design and form factor of a power supply can significantly impact its installation and overall compatibility with your system. The CORSAIR SF850 boasts a compact SFX form factor, making it an excellent choice for power-dense small-form-factor PCs. This smaller size allows for efficient use of space within a case, making it easier to manage cables and airflow.

On the other hand, the Asus ROG Strix 1200W Platinum PSU takes up more space due to its larger ATX form factor. However, it employs advanced thermal management features, including large heatsinks that enhance cooling capabilities. This means while the ROG Strix may require more space, it offers superior thermal performance, crucial for high-demand systems.

Efficiency and Performance

Efficiency is a critical factor when evaluating power supplies, and both the CORSAIR SF850 and Asus ROG Strix 1200W Platinum PSU excel in this regard. The SF850 is 80 PLUS Platinum rated, guaranteeing that it operates with high efficiency and minimal energy loss. This makes it a reliable choice for users who prioritise energy savings and an environmentally friendly option.

Conversely, the ROG Strix 1200W goes a step further with its GaN MOSFET technology, which boasts up to 30% better power efficiency compared to traditional designs. This enhanced efficiency not only reduces electricity bills but also contributes to cooler operation. For gamers and professionals seeking peak performance without compromising on energy costs, the ROG Strix offers a notable edge.

Cooling Solutions

Cooling solutions in power supplies play a pivotal role in maintaining system stability and longevity. The CORSAIR SF850 features a 92mm PWM cooling fan designed for low-noise operation while delivering effective cooling. This fan's fluid dynamic bearing ensures reliable performance, making it an excellent option for quieter builds.

In contrast, the Asus ROG Strix 1200W integrates large heatsinks that cover critical components, promoting lower temperatures and reduced noise levels compared to standard designs. Additionally, the dual ball fan bearings used in the ROG Strix can last up to twice as long as traditional sleeve bearing designs. For users focused on sustained performance during intense gaming sessions, the ROG Strix's cooling capabilities are particularly beneficial.

Modular Cabling

Modular cabling is vital for both aesthetics and ease of installation. The CORSAIR SF850 features fully modular Type-5 Micro-Fit PSU connectors, which allow users to connect only the cables they need. This flexibility leads to tidier cable management, especially in compact cases where space is at a premium.

The Asus ROG Strix 1200W, while not explicitly stated as fully modular, incorporates intelligent voltage stabilisation and superior voltage sensing. These features enhance performance and can simplify cabling requirements indirectly. However, for those who prioritise modularity and clean setups, the SF850's design makes it a more appealing choice.

Compatibility with Modern Standards

Modern compatibility is crucial for ensuring that power supplies can support the latest hardware and technologies. The CORSAIR SF850 is ATX 3.1 compliant and PCIe 5.1 ready, making it compatible with the latest graphics cards and motherboards. This compliance ensures that users can confidently invest in future hardware without facing compatibility issues.

On the other hand, the Asus ROG Strix 1200W employs "GPU-FIRST" voltage sensing technology, enhancing voltage delivery to the graphics card by up to 45%. This feature is vital for gamers looking for smoother gameplay and improved performance under load. While both power supplies offer modern compatibility, the specific advantages of the ROG Strix's voltage stabilisation technology may appeal to high-performance users.

Pricing and Value for Money

When it comes to pricing, the CORSAIR SF850 is more budget-friendly at £149.99, offering exceptional value for those needing a powerful and efficient supply for smaller systems. In contrast, the Asus ROG Strix 1200W Platinum PSU is priced at £179.99, reflecting its higher power output and advanced features.

While the ROG Strix commands a premium, its superior efficiency, cooling solutions, and voltage delivery enhancements justify the additional cost for users with demanding setups. Ultimately, the choice between these two power supplies will hinge on your specific power needs and budget constraints.

Which should you buy?

The decision between the CORSAIR SF850 and the Asus ROG Strix 1200W Platinum PSU boils down to your specific requirements. If you're looking for a compact, efficient power supply for a small-form-factor PC, the SF850 is an excellent choice, especially given its price of £149.99. However, if you need more power and advanced features for a high-performance gaming rig, the Asus ROG Strix at £179.99 offers superior efficiency and enhanced voltage delivery. Your ideal choice depends on your system’s power demands and your budget, ensuring you select the best power supply for your needs.
