Dimension comparison
Pricing and Value
When it comes to pricing, the be quiet! Power Zone 2 850W is significantly more budget-friendly, retailing at C$187.50, compared to the ASUS ROG Strix 1200W Platinum, which costs C$329.99. This makes the Power Zone 2 a compelling option for those looking for a high-quality power supply without breaking the bank. While the ASUS model offers higher wattage at 1200W, the be quiet! Power Zone 2 delivers excellent performance for a lower price point, making it an attractive choice for mid-range systems or budget-conscious gamers.
Efficiency and Certification
The ASUS ROG Strix 1200W Platinum is 80 PLUS Platinum certified, ensuring high energy efficiency. It utilises low-ESR capacitors and premium components to achieve this industry-leading efficiency. On the other hand, the be quiet! Power Zone 2 also boasts an 80 PLUS Platinum certification, with an energy efficiency rating of up to 94.1%. This means both power supplies are designed to minimise power consumption and heat generation, but the be quiet! model slightly edges ahead in terms of specific efficiency rating, making it a great choice for users aiming to reduce electricity costs.
Cooling Technology
In terms of cooling technology, the ASUS ROG Strix features large ROG heatsinks that cover critical components, ensuring lower temperatures and noise levels. This design helps maintain optimal operating conditions even during intense gaming sessions. Conversely, the be quiet! Power Zone 2 employs a semi-passive zero-RPM cooling feature, allowing its Pure Wings 3 fan to turn off entirely under low loads, resulting in silent operation. When the load increases, the fan activates, providing necessary cooling. This innovative cooling approach gives the Power Zone 2 an edge in silent operation during lighter tasks.
Compatibility and Future-Proofing
Both power supplies are ATX 3.1 compatible, ensuring they meet modern standards for power delivery. The ASUS ROG Strix 1200W Platinum includes a native 12V-2x6 connector, making it ready for next-gen graphics cards, and emphasises enhanced voltage delivery. Similarly, the be quiet! Power Zone 2 comes with native integration of the 12V-2x6 connector and three PCIe 6+2-pin connectors, making it versatile enough to support both current and next-generation graphics cards. This compatibility feature is crucial for users looking to future-proof their systems.
Build Quality and Warranty
The ASUS ROG Strix 1200W Platinum is backed by a robust 10-year warranty, underscoring its build quality and reliability. It features dual ball fan bearings that can last up to twice as long as traditional sleeve bearings, ensuring long-lasting performance. In contrast, the be quiet! Power Zone 2 does not specify its warranty period in the provided details, which may raise questions about its long-term reliability. However, it boasts a design rooted in German engineering, suggesting a commitment to quality.
Noise Levels
Noise levels are an important consideration for many users, particularly gamers and professionals who work in quiet environments. The ASUS ROG Strix 1200W Platinum leverages its 0dB technology, allowing for silent operation during light gaming sessions. On the other hand, the be quiet! Power Zone 2 remains exceptionally silent across all load scenarios, thanks to its semi-passive cooling design, which keeps the fan off under low loads. This feature allows users to enjoy a quieter computing experience, especially during less demanding tasks.
Performance Under Load
The ASUS ROG Strix 1200W Platinum is designed to deliver top-tier performance and unwavering stability for high-end systems. Its advanced GaN MOSFET technology enhances power efficiency and voltage regulation significantly. In contrast, the be quiet! Power Zone 2 provides 850W of continuous power with one massive 12V rail, capable of handling short-term power excursions up to double its rated power. This ensures reliable performance even under demanding conditions, making the Power Zone 2 a strong contender for users with high-performance needs.
Which should you buy?
Ultimately, the choice between the ASUS ROG Strix 1200W Platinum and the be quiet! Power Zone 2 850W will depend on your specific needs and budget. If you require a high-wattage power supply with advanced features and a long warranty, the ASUS ROG Strix 1200W Platinum is an excellent choice, albeit at a higher price point of C$329.99. However, if you are looking for a more affordable option that still offers high efficiency, quiet operation, and future-proofing capabilities, the be quiet! Power Zone 2 at C$187.50 stands out as an exceptional value. Each product has its unique strengths, catering to different user preferences and system requirements.
