The RM1000x (2021) power supply is built with 100% industrial-grade, 105°C rated Japanese capacitors. These capacitors are known for their superior quality and reliability, ensuring unwavering power delivery to your system. The high-temperature rating guarantees the capacitors’ durability and stability even under demanding conditions, making the power supply a reliable choice for long-term usage.
Pro-tip: When using the power supply in extreme environments or under heavy loads, ensure that your system has sufficient cooling to avoid excessive heat buildup. Providing adequate airflow around the power supply and components will help maintain optimal performance and extend the lifespan of the capacitors.
Supports Modern Standby Sleep Mode
The Corsair RM1000x (2021) power supply supports Modern Standby sleep mode, which enables extremely fast wake-from-sleep times and improves low-load efficiency. This feature reduces system power consumption during idle periods by keeping certain components in a low-power state while still allowing instant access to your system when needed. It ensures energy savings without sacrificing responsiveness.
Pro-tip: To take full advantage of the Modern Standby sleep mode, enable this feature in your system’s power settings and configure your operating system to use this low-power state when the system is idle. This will optimize energy efficiency and enhance the overall user experience without compromising performance.
