CORSAIR RM850e Fully Modular Low-Noise ATX Power vs Thermaltake Toughpower GX2 80+ Gold 600W

Overview of the Power Supplies

When it comes to power supplies, the CORSAIR RM850e and the Thermaltake Toughpower GX2 both stand out in their respective categories. The RM850e, priced at $94.99, offers a fully modular design, while the Toughpower GX2 is a non-modular power supply available for a budget-friendly $59.99. This article compares their features, performance, and value to help you make an informed decision.

Design and Modularity

The CORSAIR RM850e features a fully modular design, allowing users to connect only the cables necessary for their build. This ensures a cleaner and more organized setup, reducing clutter within the case. In contrast, the Thermaltake Toughpower GX2 employs a non-modular design, meaning all cables are hardwired. While this may simplify installation for some, it can result in excess cables that are not used, potentially leading to poor airflow and aesthetics.

Efficiency Ratings

Efficiency is a crucial factor when choosing a power supply. The CORSAIR RM850e boasts a Cybenetics Gold efficiency rating, meaning it operates at high efficiency, reducing energy waste and heat generation. The Toughpower GX2 also holds an 80 Plus Gold certification, allowing it to achieve up to 90% efficiency. While both power supplies are efficient, the CORSAIR unit's advanced engineering and certification provide a slight edge in performance, particularly under demanding loads.

Cooling Solutions

Cooling is vital for maintaining optimal performance in power supplies. The RM850e features a 120mm rifle bearing fan designed to operate quietly, even under full load. This focus on low noise makes it ideal for users who prioritize a silent PC setup. On the other hand, the Toughpower GX2 is equipped with a 120mm dynamic bearing fan that also aims for quiet operation. However, the RM850e’s specifically calculated fan curve may result in more efficient cooling, especially during demanding application scenarios.

Capacitor Quality

In terms of component quality, the CORSAIR RM850e uses 105°C-rated capacitors, which are designed to deliver reliable power and performance over time. This high-temperature rating indicates durability and stability, especially in high-performance systems. The Toughpower GX2 features high-quality capacitors as well, but it does not specify a temperature rating, which may raise questions about its long-term reliability compared to the RM850e. This distinction could be crucial for users who push their systems to the limit.

Compatibility and Connectivity

The CORSAIR RM850e is designed to be compatible with modern hardware, supporting ATX 3.1 and PCIe 5.1 standards. It includes a native 12V-2x6 connector, making it suitable for the latest GPUs that demand higher power levels. The Toughpower GX2, while also versatile, is designed for older ATX 12V V2.4/EPS V2.92 standards and includes multiple connectors, including two PCI-E connectors. However, it may not accommodate the newest GPU technologies as seamlessly as the RM850e.

Warranty and Support

Warranty terms are an important consideration for power supply purchases. The CORSAIR RM850e comes with a generous seven-year warranty, reflecting the manufacturer's confidence in its product's durability and reliability. In contrast, the Toughpower GX2 is backed by a five-year warranty. While both warranties are respectable, the longer coverage period of the RM850e may provide additional peace of mind for users concerned about long-term performance.

Price Comparison

When comparing prices, the CORSAIR RM850e's current price of $94.99 is about 58% more expensive than the Toughpower GX2, which retails for $59.99. This price difference reflects the additional features and higher specifications of the RM850e, including its fully modular design and superior efficiency ratings. For budget-conscious consumers, the Toughpower GX2 presents a compelling option without sacrificing essential power supply functions.

Which should you buy?

Choosing between the CORSAIR RM850e and the Thermaltake Toughpower GX2 ultimately depends on your specific needs and budget. If you require a high-performance, fully modular power supply that supports the latest technology with excellent efficiency and cooling, the CORSAIR RM850e is the superior choice, albeit at a higher price. However, if you are looking for a more budget-friendly option that still delivers dependable power for less demanding builds, the Thermaltake Toughpower GX2 is a solid and reliable choice.
