ASUS ROG Strix 1200W Platinum vs Rosewill VMG 850W 80+ Gold, ATX 3.0 & 3.1

Pricing Comparison

The ASUS ROG Strix 1200W Platinum is priced at $264.99, while the Rosewill VMG 850W 80+ Gold is significantly cheaper at $74.97, making it about 72% less expensive. This substantial price difference can be a decisive factor for many buyers. While the ASUS power supply offers higher wattage and advanced features, the Rosewill provides solid performance at a considerably lower cost. For budget-conscious consumers or those with less demanding power needs, the Rosewill may present a more attractive option without sacrificing quality.

Power Output and Efficiency

The ASUS ROG Strix 1200W Platinum delivers 1200 watts of power, making it ideal for high-performance gaming rigs and demanding setups. Its 80 PLUS Platinum certification indicates superior efficiency, utilizing low-ESR capacitors and premium components to achieve this. In contrast, the Rosewill VMG 850W 80+ Gold, while still efficient, has a lower maximum output of 850 watts and is certified as 80 PLUS Gold. This means it is slightly less efficient than the ASUS model but still provides good performance for most gaming and professional applications, especially at its lower price point.

Modular Design

Both the ASUS ROG Strix 1200W Platinum and the Rosewill VMG 850W feature full modular designs, allowing users to connect only the cables they need for their setup. This not only helps with cable management but also improves airflow within the case. However, the ASUS power supply utilizes GaN MOSFET technology, which enhances power efficiency by up to 30% and contributes to a more organized internal layout. This advanced design can lead to cooler operation compared to traditional designs. The Rosewill, while also modular, does not specify such advanced technology, which may result in a less efficient setup.

Thermal Management

The ASUS ROG Strix is equipped with large heatsinks and dual ball fan bearings, ensuring lower temperatures and reduced noise levels compared to standard designs. Its 0dB technology allows for silent operation during light gaming sessions. On the other hand, the Rosewill VMG features a 120mm FDB silent fan and optimized thermal control with a steel shell and large vents for enhanced cooling. While both power supplies focus on minimizing noise and managing heat effectively, the ASUS model appears to have a slight edge in overall thermal efficiency due to its advanced cooling technologies.

Compatibility and Future-Proofing

The ASUS ROG Strix 1200W is ATX 3.1 compatible and features a native PCIe 5.0 12V-2x6 connector, making it well-suited for next-gen graphics cards and ensuring high performance for future builds. The Rosewill VMG, while also compatible with ATX 3.0 and 3.1, features a PCIe 5.1 12V-2x6 cable that delivers up to 600W directly to new graphics cards. Although both power supplies support the latest standards, the ASUS model’s higher wattage and advanced voltage regulation technology may provide more stable performance under heavy loads, particularly for gamers and enthusiasts looking to push their setups to the limit.

Warranty and Reliability

The ASUS ROG Strix comes with an impressive 10-year warranty, reflecting the manufacturer's confidence in its durability and performance. This is significantly longer than the Rosewill VMG's 5-year warranty, which, while still commendable, may not offer the same level of assurance over the long term. A longer warranty can be an essential factor for users investing in high-end components, as it indicates a commitment to quality and reliability from the manufacturer.

Customer Support and Brand Reputation

ASUS is a well-established brand known for its high-quality gaming components and reliable customer support. The company has built a strong reputation among gamers and PC builders for delivering performance-driven products. Rosewill, while respected in the industry, does not have the same level of recognition as ASUS. This difference in brand reputation may influence potential buyers who prioritize customer service and overall brand reliability, especially when making a significant investment in their system's power supply.

Which should you buy?

Choosing between the ASUS ROG Strix 1200W Platinum and the Rosewill VMG 850W 80+ Gold ultimately depends on your specific needs and budget. If you require a high-output power supply with excellent efficiency, advanced cooling technology, and a long warranty, the ASUS model is the clear winner, albeit at a higher price of $264.99. However, if you are looking for a more affordable option that still meets modern standards and offers solid performance for mid-range systems, the Rosewill at $74.97 is a compelling choice.
