Asus ROG Strix 1200W Platinum PSU vs SAMA G850 Power Supply - 850W Fully Modular 80 Plus Gold Certified ATX 3.1 & PCI

Price Comparison

The Asus ROG Strix 1200W Platinum PSU is priced at £179.99, while the SAMA G850 Power Supply retails for £84.99. This represents a significant difference of £95 between the two products. The higher price of the Asus PSU reflects its advanced features and capabilities, positioning it as a premium option for high-performance builds. In contrast, the SAMA G850 offers a more budget-friendly solution without compromising on essential features, appealing to those looking for efficiency at a lower cost.

Power Output

The power output of the Asus ROG Strix is 1200W, making it suitable for high-end gaming rigs and workstations that demand substantial power. In comparison, the SAMA G850 provides 850W, which is adequate for most gaming setups but may limit the ability to run multiple high-end components simultaneously. This clear difference in wattage highlights the Asus PSU's capability to support more powerful hardware configurations, while the SAMA G850 caters to mid-range systems.

Efficiency Ratings

The Asus ROG Strix boasts a Platinum efficiency rating, while the SAMA G850 is certified as 80 Plus Gold. Platinum-rated power supplies are known to achieve at least 90% efficiency at typical load, whereas 80 Plus Gold units can achieve up to 91.15% efficiency. This slight edge in efficiency for the SAMA G850 may appeal to energy-conscious users, but the superior efficiency of the Asus PSU provides enhanced performance and lower energy costs over time, particularly for demanding applications.

Build Quality and Design

The Asus ROG Strix features GaN MOSFET technology, which enhances power efficiency by up to 30% and aids in maintaining cooler operation. Additionally, it incorporates large ROG heatsinks for better thermal management and dual ball fan bearings that last up to twice as long as standard designs. On the other hand, the SAMA G850 employs high-quality Japanese capacitors and a 140mm ECO fan with Fluid Dynamic Bearing, ensuring quiet operation and stability. While both units exhibit strong build quality, the Asus offers more advanced thermal management features, making it ideal for intensive use.

Cable Management

When it comes to cable management, the SAMA G850 excels with its fully modular design, allowing users to connect only the cables they need. This design promotes better airflow and a cleaner build aesthetic. In contrast, the Asus ROG Strix does not explicitly mention a modular design, which could lead to a more cluttered interior if unnecessary cables are left connected. The fully modular layout of the SAMA G850 makes it a more attractive option for users prioritising neatness in their builds.

Cooling Solutions

The Asus ROG Strix implements advanced cooling solutions with its large heatsinks and dual ball fan bearings, which contribute to lower temperatures and reduced noise. The 0dB technology allows for silent operation during light gaming sessions. Conversely, the SAMA G850 features a silent 140mm fan with Fluid Dynamic Bearing, offering quiet cooling and vibration damping. While both power supplies focus on effective cooling, the Asus ROG Strix may provide superior thermal performance under heavy loads due to its additional features.

Compatibility with Modern Components

The SAMA G850 is designed with modern gaming setups in mind, featuring an ATX 3.1 standard and a native 12V-2x6 connector compatible with NVIDIA GeForce RTX 50 and 40 Series GPUs. This makes it a future-proof option for gamers looking to upgrade their graphics cards. Meanwhile, the Asus ROG Strix is also well-equipped for contemporary demands but does not highlight specific compatibility with the latest graphics card standards. This makes the SAMA G850 particularly appealing for users planning to invest in current-generation GPUs.

Which should you buy?

Choosing between the Asus ROG Strix 1200W Platinum PSU and the SAMA G850 Power Supply ultimately depends on your specific needs and budget. If you require high power output and advanced features for an intensive gaming or workstation setup, the Asus ROG Strix is the clear winner, albeit at a higher price point of £179.99. However, if you're looking for a cost-effective solution that still delivers solid performance and efficiency, the SAMA G850 at £84.99 offers great value. Each product has its strengths, making the decision largely dependent on your performance requirements and budget constraints.
