CORSAIR SF850 vs ASUS ROG Thor 1200W Platinum III PSU

Price Comparison

When it comes to price, the CORSAIR SF850 is significantly more affordable at C$279.99 compared to the ASUS ROG Thor 1200W Platinum III PSU, which costs C$552.99. This means the ASUS power supply is about 97% more expensive than the CORSAIR model. If budget is a primary concern, the CORSAIR SF850 offers a compelling option without compromising on power efficiency or performance for smaller setups.

Power Output

The ASUS ROG Thor 1200W Platinum III PSU boasts a maximum output of 1200 watts, making it ideal for high-performance systems that require significant power. In contrast, the CORSAIR SF850 provides up to 850 watts, which is sufficient for most mid-range configurations. If you are building a system with multiple high-end graphics cards or extensive peripherals, the extra power from the ASUS unit may be necessary.

Efficiency Ratings

Both power supplies are 80 PLUS Platinum rated, indicating high energy efficiency. However, the ASUS ROG Thor leverages GaN MOSFET technology, which delivers up to 30% more power efficiency than standard MOSFETs. This enhanced efficiency can lead to lower power bills and reduced heat generation over time, making the ASUS model more attractive for users focused on energy savings in the long run.

Cooling Mechanisms

Cooling is crucial for maintaining performance and longevity in power supplies. The CORSAIR SF850 features a 92mm PWM cooling fan designed for low-noise operation, while the ASUS ROG Thor incorporates premium components and a fine-tuned fan curve that unlocks support for extended power excursions. This advanced cooling design helps the ASUS unit manage higher thermal loads effectively, which is essential for power-hungry systems.

Modularity and Cabling

The CORSAIR SF850 is fully modular with Type-5 Micro-Fit PSU connectors, allowing for tidy cable management and flexibility in small cases. This modularity is a significant advantage for users looking to minimise cable clutter in compact builds. The ASUS ROG Thor also offers modularity but focuses more on premium components and internal layout. Depending on your case size and cable management preferences, either could be a suitable choice.

Special Features

The ASUS ROG Thor includes unique features such as a magnetic OLED display that shows real-time power draw, which can be swapped to accommodate various PSU installations. This feature adds a layer of convenience for users wanting to monitor their power usage directly. The CORSAIR SF850, while lacking such an innovative display, still provides a robust performance with its ATX 3.0 compliance and PCIe 5.0 readiness, making it future-proof for upcoming technologies.

Warranty and Reliability

Reliability is paramount in power supplies, and the ASUS ROG Thor stands out with a generous 10-year warranty, reflecting its build quality and durability. In contrast, the warranty period for the CORSAIR SF850 is not specified in the provided data, making the ASUS unit a potentially safer investment for long-term use. Customers seeking assurance in their purchase may gravitate towards the ASUS model due to this extensive warranty.

Which should you buy?

Choosing between the CORSAIR SF850 and the ASUS ROG Thor 1200W Platinum III PSU largely depends on your specific needs and budget. If you are looking for a cost-effective solution for a mid-range build, the CORSAIR SF850 at C$279.99 provides excellent power efficiency and modularity. However, for users planning high-performance setups with demanding power requirements, the ASUS ROG Thor at C$552.99 offers superior power output, advanced cooling, and unique features like a magnetic OLED display. Ultimately, your choice should reflect your budget and performance expectations.
