80 PLUS BRONZE CERTIFIED
80 Plus Bronze certified ensures to deliver 85% efficiency at 50% load. The better power efficiency leads to less power waste, less heat and less fan noise.
Reliable Flat Cable
P550B provides the best solution for the system builds. The flat cable reduces the clutter and improves the airflow in the case.
120mm Silent Hydraulic Bearing (HYB) Fan
120mm Silent Hydraulic Bearing fan optimizes the noise reduction and the thermal performance. The fan speed is adjusted according to the automatic power detection. The Hydraulic Bearing fan provides longer and more stable life time.
SINGLE +12V RAIL
Single +12V rail provides the best power output, stability and compatibility for the hardware. It provides the easiest way to install the power cable. And it is the best design for overclocking.
PROTECTION
In order to make sure the entire computer system to operate stably under any conditions, we not only added protection designs such as OCP, OTP, OVP, OPP, UVP and SCP, but also ensured the stable operation of your system through the safety certification of various countries.
