CORSAIR SF850 vs ASUS ROG Strix 1200W Platinum

Pricing

When it comes to pricing, the CORSAIR SF850 is more affordable than the ASUS ROG Strix 1200W Platinum. The SF850 is priced at C$279.99, while the ROG Strix comes in at C$329.99. This difference of C$50 makes the CORSAIR SF850 a more budget-friendly option, particularly for those who are seeking high-quality performance without breaking the bank. Both power supplies offer premium features, but the price point of the SF850 may appeal more to gamers and builders who are looking to keep costs down while still achieving high efficiency.

Power Efficiency

Both power supplies boast impressive efficiency ratings, but the ASUS ROG Strix 1200W Platinum has an edge with its advanced GaN MOSFET technology. This feature delivers superior power efficiency, improving overall performance by up to 30%. In comparison, the CORSAIR SF850 is also 80 PLUS Platinum rated, ensuring high levels of energy efficiency, but it lacks the cutting-edge technology that enhances the ROG Strix's performance. As a result, gamers prioritising efficiency in their builds might find the ASUS ROG Strix the more appealing option.

Cooling Performance

Cooling performance is critical for maintaining system stability during demanding tasks. The ASUS ROG Strix 1200W Platinum features large heatsinks and dual ball fan bearings, which ensure lower temperatures and noise levels compared to standard designs. The dual ball bearings can last up to twice as long as conventional sleeve designs, enhancing durability. Meanwhile, the CORSAIR SF850 utilises a 92mm PWM cooling fan that operates quietly while delivering effective cooling. Although both power supplies excel in cooling, the ROG Strix's design provides superior temperature management, making it a stronger choice for high-performance gaming rigs.

Compatibility

Compatibility is another crucial factor to consider. The CORSAIR SF850 is ATX 3.0 compliant and PCIe 5.0 ready, making it suitable for the latest hardware requirements. This ensures that it can handle transient power spikes effectively. On the other hand, the ASUS ROG Strix 1200W Platinum is ATX 3.1 compatible, which guarantees enhanced voltage and current regulation, alongside being PCIe 5.0 ready with a native 12V-2x6 connector. While both units support the latest technology, the ROG Strix’s compliance with the newer ATX 3.1 standard makes it a more future-proof option for gamers looking to invest in cutting-edge hardware.

Build Quality

In terms of build quality, the ASUS ROG Strix 1200W Platinum is designed to offer a more robust construction. It utilises low-ESR capacitors and premium components that contribute to its 80 PLUS Platinum certification, ensuring reliability and efficiency. Furthermore, the 10-year warranty included with the ROG Strix underscores its durability and the manufacturer's confidence in its performance. Conversely, while the CORSAIR SF850 is also well-constructed and features 105°C rated Japanese capacitors, it does not come with the same extended warranty. This distinction may influence buyers who value long-term reliability and support in their power supply choices.

Noise Levels

Noise levels are an important consideration for users who prefer a quieter computing environment. The ASUS ROG Strix 1200W Platinum incorporates 0dB technology, allowing for silent operation during light gaming sessions. This is an attractive feature for gamers who want to enjoy an immersive experience without distracting noise. The CORSAIR SF850, with its fluid dynamic bearing fan, also operates quietly but may not achieve the same level of silence under low loads as the ROG Strix. For users prioritising a noiseless experience, the ROG Strix offers a distinct advantage.

Brand Reputation

Brand reputation can play a significant role in purchasing decisions. Corsair is widely known for its high-quality components, particularly in the realm of power supplies, while Asus's ROG line is synonymous with premium gaming hardware. Both brands have established trust within the gaming community, but Asus generally caters to the higher-end market with its ROG products. This reputation for premium quality and performance might sway consumers towards the ASUS ROG Strix 1200W Platinum, especially those who are building high-performance gaming setups.

Which should you buy?

Choosing between the CORSAIR SF850 and the ASUS ROG Strix 1200W Platinum ultimately depends on your specific needs and budget. If you are looking for a more affordable option that still provides excellent performance and efficiency, the CORSAIR SF850 is a strong contender at C$279.99. However, if you require advanced features like superior power efficiency, enhanced cooling, and a longer warranty, the ASUS ROG Strix 1200W Platinum at C$329.99 may be the better investment. Consider your priorities in terms of price, performance, and future-proofing when making your decision.
