The Corsair RM750x is part of Corsair’s RM series, known for high efficiency and quiet operation. It features 80 Plus Gold certification, ensuring energy efficiency and lower electricity bills. The power supply is fully modular, making cable management easier and cleaner. Its build quality is highly regarded, with Japanese capacitors for durability and stability. The RM750x is designed to operate quietly, even under heavy loads, thanks to its low-noise fan.
Overview of Thermaltake Toughpower Gx2 750W
The Thermaltake Toughpower Gx2 750W is a reliable power supply that offers solid performance for gamers and enthusiasts. It boasts 80 Plus Gold certification, ensuring high efficiency. Its design emphasizes durability, with high-quality components and protections against overcurrent, overvoltage, and short circuits. The Gx2 series features a semi-modular design, allowing for flexible cable management. It is known for stable power delivery and good thermal performance.
Efficiency and Certification
Both power supplies are 80 Plus Gold certified, meaning they deliver at least 87% efficiency at 20% load, 90% at 50% load, and 87% at 100% load. This high efficiency reduces wasted energy and heat, contributing to lower electricity bills and quieter operation. The Corsair RM750x slightly edges out in terms of overall efficiency consistency, but both are excellent choices in this regard.
Build Quality and Components
The Corsair RM750x features high-quality Japanese capacitors, known for their longevity and stability. Its fully modular design allows for easy cable management and a cleaner build.
