Price Comparison
When considering price, the ASRock PRO-650G is significantly more budget-friendly at $49.99, compared to the ASUS TUF Gaming 1200W Gold, which retails for $204.99. This difference of $155 highlights that the ASRock model is about 24% of the price of the ASUS, making it an attractive option for those on a tight budget. While the ASUS PSU offers more wattage and advanced features, the price gap is substantial for users who may not require the extra power or premium features.
Power Output
The ASUS TUF Gaming 1200W Gold provides a hefty 1200 watts of power, which is double that of the ASRock PRO-650G at 650 watts. This difference makes the ASUS a better choice for high-performance systems, especially those equipped with multiple graphics cards or demanding components. In contrast, the ASRock is sufficient for mid-range gaming and productivity systems. Thus, if your build requires extensive power, the ASUS is the clear winner.
Efficiency Ratings
Both power supplies boast an 80 PLUS Gold certification, ensuring high energy efficiency. The ASRock PRO-650G delivers up to 90% efficiency, reducing power consumption and heat output, which is beneficial for cost-effective operation. The ASUS TUF Gaming 1200W Gold also meets this standard, backed by premium components like Japanese capacitors. While both units offer excellent efficiency, the performance in real-world applications may vary depending on the components they power.
Build Quality
The ASUS TUF Gaming 1200W Gold is built with military-grade components and features a protective PCB coating, which enhances durability against moisture, dust, and extreme temperatures. This construction is complemented by dual ball bearing fans that can last up to twice as long as standard sleeve bearings. The ASRock PRO-650G, while also equipped with high-quality all-Taiwanese capacitors, does not specify such robust protection features. Therefore, for users prioritizing long-term reliability in challenging environments, the ASUS stands out.
Cooling Solutions
Cooling is a significant consideration for power supplies, and both units feature dedicated fans for optimal performance. The ASRock PRO-650G includes a quiet 120mm fan that balances cooling and noise levels, making it suitable for quieter builds. Conversely, the ASUS TUF Gaming 1200W Gold incorporates a more advanced axial-tech fan design, which is likely to provide superior airflow and cooling efficiency. This makes the ASUS a better choice for users who may run their systems under heavy loads for extended periods.
Warranty and Support
In terms of warranty, the ASUS TUF Gaming 1200W Gold offers an impressive 10-year warranty, providing peace of mind for long-term use. The ASRock PRO-650G, while still backed by a solid 3-year warranty, does not match the extensive coverage offered by the ASUS. A longer warranty can be a crucial factor for users who wish to invest in a power supply for a long-term setup, making the ASUS a more secure option.
Compatibility and Installation
The ASRock PRO-650G is ATX 3.1 compatible and fits the standard ATX form factor, ensuring it can work with most PC cases. It features a flat cable design that simplifies installation and improves airflow. Similarly, the ASUS TUF Gaming 1200W Gold is ATX 3.0 compatible and fully modular, allowing for easier cable management and customization. Both power supplies cater to modern systems, but the fully modular design of the ASUS provides an edge in terms of ease of installation and aesthetics.
Which should you buy?
Deciding between the ASRock PRO-650G and the ASUS TUF Gaming 1200W Gold ultimately depends on your specific needs. If you are looking for a cost-effective solution for a mid-range build, the ASRock’s lower price of $49.99 and adequate performance make it an appealing choice. However, for high-performance gaming rigs or systems requiring extensive power and features, the ASUS with its robust build quality, higher wattage, and longer warranty at $204.99 is likely the better investment.
