GIGABYTE P550SS ICE + Ice white aesthetics + 80 PLUS Silver certified + Support Intel ATX 3.0 standard + 120mm Fluid Dynamic Bearing (FDB) Fan + Flat cable design + Powerful single +12V rail + OVP/OPP/SCP/UVP/OCP/OTP protection 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 ICE 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.
