Does what it is meant to. Upgraded from 2080ti to 7900xtx and gpu runs fine - reaches 520w in some benchmarks (albeit not all components running) and haven’t had any issues in games with average watts of 400w. Recommend, good quality for price, and in the top tiers for PSU ratings.

Pros:Power Capacity: With its 1000 Watt capacity, the RM1000x offers more than enough power to handle high-end components like the RX 7900 XTX graphics card and other power-hungry components. This ensures stable and efficient power delivery even during demanding tasks or gaming sessions.Efficiency: The 80 PLUS Gold certification indicates that the power supply is highly efficient, converting more power from the wall outlet into usable power for your PC components. This can help reduce electricity costs and waste heat, keeping your system running cooler.Fully Modular Design: The fully modular design allows you to connect only the cables you need, minimizing cable clutter inside your case. This not only improves airflow but also makes cable management easier during the build process.Build Quality: Corsair is well-known for producing high-quality PC components, and the RM1000x is no exception. The power supply is built with premium components, which contribute to its overall reliability and longevity.Quiet Operation: The RM1000x features a Zero RPM fan mode, which means the fan won't spin at low to moderate loads, resulting in quieter operation. This is especially beneficial during light computing tasks or when the system is idle.Overcurrent and Overvoltage Protection: Corsair equips the RM1000x with multiple safety features, such as overcurrent and overvoltage protection, to safeguard your components against power fluctuations and potential damage.Cons:Price: The RM1000x is positioned as a high-end power supply, and the fully modular design and high wattage capacity can make it relatively expensive compared to lower-end models. However, the extra cost is often justified by the added benefits and build quality.Overkill for Some Setups: Unless you are running a very power-hungry system with multiple high-end components or are planning to upgrade further in the future, the 1000 Watt capacity might be overkill for some users. A lower wattage model could be more cost-effective for more modest setups.Overall, the Corsair RM1000x is an excellent choice for enthusiasts and gamers who demand a robust, high-performance power supply to support their powerful components. It's efficient, reliable, and has a modular design, making it a top-tier option for those willing to invest in quality hardware.
