Price Comparison
The ASUS ROG Strix 1200W Platinum is priced at $264.99, making it significantly more expensive than the Thermaltake Toughpower GT 850W, which retails at $95.52. This means the ASUS power supply is about 177% more expensive than its competitor. The price difference may reflect the ASUS unit's higher wattage and premium features, but for budget-conscious buyers, the Thermaltake option offers a compelling choice without breaking the bank.
Power Output
When it comes to power output, the ASUS ROG Strix 1200W Platinum leads with a robust 1200 watts, compared to the Thermaltake Toughpower GT's 850 watts. This difference of 350 watts can be significant for users running high-end gaming rigs or multiple graphics cards, as the additional wattage ensures stable performance under heavy loads. The higher output of the ASUS unit is particularly beneficial for enthusiasts looking to push their systems to the limit.
Efficiency Ratings
The ASUS ROG Strix 1200W Platinum boasts an 80 PLUS Platinum certification, indicating superior efficiency, while the Thermaltake Toughpower GT holds an 80 PLUS Gold certification. The Platinum certification signifies that the ASUS unit can deliver up to 92% efficiency, compared to the Gold's maximum of about 90%. This higher efficiency lowers energy consumption and heat output, making the ASUS a more environmentally friendly option in the long run, especially for power-hungry setups.
Build Quality and Design
In terms of build quality, both power supplies feature fully modular designs, which facilitate better cable management and airflow. However, the ASUS ROG Strix 1200W Platinum incorporates advanced GaN MOSFET technology, enhancing power efficiency and cooling. It also includes large ROG heatsinks, which help in keeping temperatures down and noise levels low. While the Thermaltake Toughpower GT also features a 120mm hydraulic bearing fan and Smart Zero Fan technology to minimize noise, the overall premium components in the ASUS unit may appeal more to those seeking high performance.
Cooling Solutions
Cooling is crucial for maintaining performance and longevity in power supplies. The ASUS ROG Strix 1200W Platinum features dual ball fan bearings, which can last up to twice as long as traditional sleeve bearing designs, ensuring reliable operation. Additionally, its 0dB technology allows for silent running during light gaming sessions. On the other hand, the Thermaltake Toughpower GT employs Smart Zero Fan technology, which adjusts the fan speed based on load. While both units have effective cooling solutions, the ASUS offers a more advanced system that might be better suited for extreme gaming scenarios.
Warranty and Support
Warranty offerings can significantly impact buyer confidence. The ASUS ROG Strix 1200W Platinum comes with a generous 10-year warranty, demonstrating the brand’s confidence in its product's longevity and reliability. In contrast, the Thermaltake Toughpower GT provides a 5-year warranty, which, while still respectable, is half the duration of the ASUS warranty. This extended coverage for the ASUS model can be a crucial factor for users who want peace of mind regarding their investment.
Compatibility and Features
Regarding compatibility, both power supplies support the latest ATX 3.1 standards and feature native PCIe 5.1 connectors for modern graphics cards. However, the ASUS ROG Strix 1200W Platinum enhances voltage delivery with its "GPU-First" voltage sensing and patented intelligent voltage stabilizer, which boosts voltage delivery to the graphics card by up to 45%. This feature can lead to smoother gameplay and better performance under load, providing a clear advantage for gamers who prioritize performance.
Which should you buy?
Choosing between the ASUS ROG Strix 1200W Platinum and the Thermaltake Toughpower GT 850W ultimately depends on your specific needs. If you require maximum power output, efficiency, and features tailored for high-performance systems, the ASUS unit is the superior choice, despite its higher price. However, for users who are more budget-conscious and still need a reliable power supply for moderate gaming or workstation builds, the Thermaltake Toughpower GT offers excellent value for money with its solid efficiency and good performance.
