ThermalProtect 12V-2x6 Cable
The included ThermalProtect 12V-2x6 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.

Your guarantee of reliable operation for peace of mind through multiple builds
