Overview

  • ThermalProtect 12V-2×6 Cable
    The included ThermalProtect 12V-2×6 cable has built-in Over Temperature Protection (OTP) which actively monitors the temperature of the cable. If the sensor detects extreme temperatures, ThermalProtect activates, causing the GPU to shut down to prevent potential damage.
  • Cybenetics Platinum-certified
    Steady power output at up to 91% efficiency, ensuring lower power consumption and cool operation.
  • Intel® ATX 3.1 Certified and PCIe 5.1 Compliant
    Certified to meet the ATX 3.1 power standard and PCIe 5.1 compliant for modern systems.
  • 105°C-Rated Capacitors
    A resilient design guarantees reliable power delivery even under harsh conditions.
  • Keep the Noise Down
    Rated A+ for noise from Cybenetics, using the most advanced and comprehensive testing methodologies available.
  • Zero RPM Fan Mode
    Stops the fan from spinning at low loads for near-silent operation.
  • Low-Noise 120mm Rifle-Bearing Fan
    The internal fan features a custom-tuned fan curve that ensures quiet operation for daily tasks, with fan noise ramping up very slowly as load on the PSU increases.
  • Compact Size
    At just 140mm long, the RMe series power supplies are shorter than a traditional power supply, offering more room for cable management and making them great for mid towers and smaller cases.
  • Debossed Cables with Low-Profile Combs
    Sleek, ultra-flexible debossed cables are easy to route to their exact location and make cable management a breeze, even in tight spaces.
  • Fully-Modular Design
    Only connect the cables your system needs for easy cable management and better internal airflow.
  • Seven-Year Warranty
    Your guarantee of reliable operation for peace of mind through multiple builds
