be quiet! Pure Power 13 M 1000W Power Supply vs Asus ROG Strix 1200W Platinum PSU

Price Comparison

When it comes to price, the be quiet! Pure Power 13 M 1000W Power Supply is significantly more affordable at £99.99 compared to the Asus ROG Strix 1200W Platinum PSU, which is priced at £179.99. This £80 difference is substantial, particularly for budget-conscious consumers or those assembling a gaming rig without breaking the bank. The Pure Power 13 M offers excellent efficiency and features at a lower price point, making it an attractive option for those seeking reliable performance without a hefty investment.

Efficiency Ratings

The be quiet! Pure Power 13 M boasts an impressive 80 PLUS Gold certification, with an efficiency rating of up to 94.4%. This high level of efficiency translates to lower power consumption, resulting in reduced electricity costs and a cooler operating environment. In contrast, while the specifics of the Asus ROG Strix's efficiency rating are not detailed, its GaN MOSFET technology promises superior power efficiency improvements of up to 30%. Thus, if energy efficiency is a priority, the Pure Power 13 M provides a more quantifiable assurance of lower operational costs.

Power Output

In terms of power output, the Asus ROG Strix 1200W Platinum PSU leads with a maximum output of 1200W, catering to systems with high-performance components that may require more power. The be quiet! Pure Power 13 M, while slightly lower at 1000W, still offers ample power for most gaming setups and can handle power excursions up to double its rated capacity. This makes both power supplies suitable for high-demand systems, but users requiring the utmost in power delivery may lean towards the Asus offering.

Cooling Technology

The cooling systems of both power supplies exhibit advanced technology to manage heat effectively. The be quiet! Pure Power 13 M features a fan that turns off completely under low load conditions, ensuring silent operation during lighter tasks. Additionally, its airflow-optimised fan blades contribute to reduced noise levels. Meanwhile, the Asus ROG Strix incorporates large heatsinks and dual ball fan bearings that can last twice as long as traditional sleeve bearings, promising lower temperatures and noise. This suggests that while both units are designed for quiet performance, the Asus may have an edge in durability and long-term cooling efficiency.

Compatibility and Connectivity

The connectivity options differ between the two models. The be quiet! Pure Power 13 M includes native integration of the 12V-2x6 connector for next-generation PCIe 5.1 graphics cards and features four PCIe 6+2-pin connectors, making it highly versatile for both current and future GPUs. The Asus ROG Strix also emphasises compatibility with its "GPU-FIRST" voltage sensing technology, which improves voltage delivery to the graphics card by up to 45%, enhancing performance. Overall, while both power supplies cater well to modern gaming requirements, the be quiet! model offers a more straightforward approach to connectivity with its additional PCIe connections.

Build Quality and Design

The build quality of both power supplies reflects their respective brands' dedication to performance and reliability. The be quiet! Pure Power 13 M prioritises a tidy system layout through modularity, which simplifies cable management and improves airflow. This design consideration translates to lower internal temperatures and noise. Conversely, the Asus ROG Strix features premium materials and an organised internal layout, courtesy of its GaN MOSFET technology, which enhances cooling. While both models are well-designed, the Pure Power 13 M stands out for users focused on a clean and efficient installation.

Noise Levels

Noise levels are a critical consideration for many users, especially those building quiet systems. The be quiet! Pure Power 13 M excels in this area with its fan operation that ceases under low loads, resulting in a silent experience during lighter tasks. This characteristic makes it especially suited for quiet systems and gaming PCs. The Asus ROG Strix also offers noise-reduction features, such as its 0dB technology, which allows for silent operation during light gaming. However, the specific conditions under which noise levels are reduced may vary, making the be quiet! PSU a more reliable choice for users specifically prioritising silence.

Which should you buy?

Choosing between the be quiet! Pure Power 13 M 1000W Power Supply and the Asus ROG Strix 1200W Platinum PSU ultimately depends on your specific needs and budget. If you're looking for a cost-effective solution with excellent efficiency and performance for most gaming setups, the Pure Power 13 M is the ideal choice at £99.99. However, for users requiring higher power output and advanced features for extreme gaming or workstation setups, the Asus ROG Strix, despite its higher price of £179.99, offers superior capabilities. Both power supplies have their strengths, but your final decision should align with your power requirements and budget constraints.
