Description

80 PLUS
SILVER CERTIFIED
The 80 Plus Silver certification (230V EU) guarantees a 90% efficiency rate at a 50% load, resulting in reduced power wastage, diminished heat generation, and minimized fan noise.

Support Intel
ATX 3.0 standard
The P550SS can sustain up to 2x total power excursion. It is fully compatible with Intel PSDG (Power Supply Design Guide) ATX 3.0 standard which supports up to 200% power excursion, reaches 70% low load efficiency and complies with required power supply timing standards.

120MM FLUID DYNAMIC
BEARING(FDB) FAN
High-performance Fluid Dynamic Bearing fan uses oil film shock absorption technology to effectively reduce noise, making it quieter than conventional sleeve fan and providing more than twice the lifespan. In addition, the fan will detect the current power usage and temperature, automatically adjust the fan speed to minimize the noise.

RELIABLE FLAT CABLE DESIGN
The utilization of flat cables minimizes clutter while enhancing the thermal performance of the chassis.

SINGLE +12V RAIL
The single +12V rail delivers optimal power output, stability, and hardware compatibility. This design not only simplifies power cable installation but also stands as the most effective choice for overclocking purposes.

PROTECTION
To guarantee the stable operation of your entire computer system under any circumstances, we have incorporated a range of protective features including OCP, OTP, OVP, OPP, UVP, and SCP. Moreover, we have obtained safety certifications from various countries to ensure the consistent and secure functioning of your system.
