ASUS ROG Strix 1200W Platinum vs Seasonic Focus GX 850W Power Supply ATX 3.1 PCIe

Price Comparison

The ASUS ROG Strix 1200W Platinum is priced at $264.99, making it about 89% more expensive than the Seasonic Focus GX 850W, which costs $139.99. This significant price difference reflects the distinct features and specifications each power supply offers. While some users may prioritize the premium features of the ROG Strix, others may find the Seasonic provides sufficient power and efficiency for less cost, making it a compelling choice for budget-conscious consumers.

Power Output

In terms of wattage, the ASUS ROG Strix provides a robust 1200W, while the Seasonic Focus GX delivers 850W. This 35% difference indicates that the ROG Strix is suited for high-performance gaming rigs and systems with multiple graphics cards. Gamers looking to power demanding setups will benefit from the additional headroom offered by the ROG Strix. Conversely, the Seasonic, with its 850W output, caters well to mid-range builds or users who do not require extreme power for their applications.

Efficiency Ratings

The ASUS ROG Strix boasts an 80 PLUS Platinum certification, highlighting its superior efficiency and lower energy waste compared to the Seasonic Focus GX's 80 PLUS Gold rating. The ROG Strix offers up to 30% greater power efficiency, which can translate to significant cost savings over time, particularly for users who run their systems for extended periods. The Seasonic, while still efficient with its Gold rating, does not match the high standards set by the Platinum certification that the ROG Strix provides.

Build Quality and Design

The ROG Strix features GaN MOSFET technology, which not only enhances efficiency but also contributes to a cooler internal layout. The use of dual ball fan bearings in the ROG Strix promises longer lifespan and quieter operation compared to the Seasonic’s hybrid fan control. While both power supplies are fully modular, the superior cooling design in the ROG Strix can lead to better performance under load, making it particularly appealing to gamers concerned about thermal management.

Warranty and Support

The ASUS ROG Strix comes with an impressive 10-year warranty, which speaks volumes about its build quality and reliability. The Seasonic Focus GX also offers a 10-year warranty, ensuring both products are backed by strong manufacturer support. This parity in warranty length indicates that both brands have confidence in the longevity of their products, giving consumers peace of mind regardless of their choice.

Compatibility and Features

Both power supplies are designed for modern systems, with the ASUS ROG Strix supporting ATX 3.1 standards and featuring a native 12V-2x6 connector for next-gen graphics cards. The Seasonic Focus GX is also ATX 3.1 and PCIe 5.1 ready, making it compatible with the latest hardware. However, the ROG Strix's "GPU-First" voltage sensing technology enhances voltage delivery to the graphics card, which could provide a performance boost in gaming scenarios, especially at higher resolutions.

Noise Levels

The ROG Strix features 0dB technology, allowing for silent operation during light gaming, which is a significant advantage for users who prefer a quiet environment. In comparison, the Seasonic's hybrid fan control with a 135 mm FDB fan provides effective cooling but may not achieve the same level of silent performance under low loads. For gamers who prioritize a quieter gaming experience, the ROG Strix might be the more appealing option.

Which should you buy?

Deciding between the ASUS ROG Strix 1200W Platinum and the Seasonic Focus GX 850W boils down to your specific needs and budget. If you require high wattage, superior efficiency, and additional features like advanced cooling technology, the ROG Strix is the clear choice, albeit at a higher price of $264.99. On the other hand, if you’re looking for a more economical option with solid performance and efficiency for a mid-range system, the Seasonic at $139.99 is an excellent value. Ultimately, your decision should align with your gaming requirements, power needs, and budget constraints.
