ASUS ROG Strix 1200W Platinum vs MSI MPG A850G PCIE5, Fully Modular Compact Gaming

Price Comparison

The MSI MPG A850G PCIE5 is significantly more affordable, priced at $109.99, compared to the ASUS ROG Strix 1200W Platinum, which costs $264.99. This makes the MSI power supply about 58% cheaper than its ASUS competitor. For budget-conscious gamers or those building mid-range systems, the MSI option presents a compelling choice without sacrificing essential features. On the other hand, the ASUS model targets high-end users who require optimal performance and stability, justifying its higher price tag.

Power Output and Efficiency

When it comes to power output, the ASUS ROG Strix 1200W Platinum leads with a robust 1200W capacity, ideal for high-performance gaming rigs that demand more power, especially with multiple graphics cards. In contrast, the MSI MPG A850G PCIE5 delivers a solid 850W, which is sufficient for mid-range to high-end builds but may limit future upgrades for hardcore gamers. Additionally, the ASUS unit boasts an 80 Plus Platinum certification, indicating superior energy efficiency, while the MSI unit holds an 80 Plus Gold certification. This means the ASUS power supply is designed to deliver about 90% efficiency at 50% load compared to around 87% for the MSI, resulting in lower electricity bills for users who prioritize efficiency.

Features and Technology

The ASUS ROG Strix 1200W Platinum incorporates advanced technology like GaN MOSFETs, which enhance power efficiency by up to 30%. It also features GPU-First voltage sensing, ensuring a steady power supply to the graphics card, which can improve gaming performance significantly. Conversely, the MSI MPG A850G PCIE5 is also equipped with a fully modular design, allowing users to connect only the necessary cables, thus reducing clutter. While both power supplies come with a 10-year warranty, the ASUS model's advanced features make it a better fit for gamers who want the latest technology for optimal performance.

Build Quality and Components

ASUS emphasizes quality with its ROG Strix model, featuring large heatsinks and low-ESR capacitors designed for enhanced thermal management and quieter operation. The dual ball fan bearings in the ASUS unit can last up to twice as long as standard sleeve bearings, ensuring durability and longevity. The MSI MPG A850G PCIE5, on the other hand, is constructed with 100% Japanese capacitors rated for 105°C, which are known for their reliability. While both units promise excellent build quality, the ASUS power supply has an edge in terms of thermal performance and longevity, which may appeal to users who push their systems to the limit.

Noise Levels

Noise can be a critical factor for gamers, and the ASUS ROG Strix 1200W Platinum has a feature known as 0dB technology that allows for silent operation during light gaming sessions. This means that users can enjoy their games without the distraction of fan noise. The MSI MPG A850G PCIE5 does not specifically mention fan noise levels, but its design aims to maintain low noise through optimized airflow. In practice, however, the ASUS model provides a more definitive solution for those who prioritize a quiet gaming environment.

Compatibility

Both power supplies are compatible with the latest standards, including ATX 3.1 and PCIe 5.0 for the ASUS model. This makes them suitable for next-generation graphics cards and motherboards. The MSI MPG A850G PCIE5 also supports ATX 3.1 and is PCIe 5.1 ready, ensuring broad compatibility with current and future hardware. However, the ASUS unit’s additional features like GPU-First voltage sensing can provide an extra layer of performance for demanding gaming setups, making it a preferable choice for tech enthusiasts looking to future-proof their rigs.

Warranty and Support

Both the ASUS ROG Strix 1200W Platinum and the MSI MPG A850G PCIE5 come with a 10-year warranty, which reflects the manufacturers' confidence in their product quality. This extended warranty period is beneficial for users looking for long-term reliability. However, the overall reputation of ASUS for customer support and warranty service may offer additional peace of mind for buyers investing in a premium product like the ROG Strix, compared to MSI's offerings in this category.

Which should you buy?

Choosing between the ASUS ROG Strix 1200W Platinum and the MSI MPG A850G PCIE5 ultimately depends on your specific needs and budget. If you are building a high-end gaming rig that requires maximum power output, advanced technology, and superior efficiency, the ASUS model is worth the investment despite its higher price. However, if you are looking for a cost-effective solution that still delivers reliable performance for a mid-range setup, the MSI power supply is an excellent choice at about 58% less than the ASUS option.
