SFX Form Factor, ATX-Class Performance
The SilverStone 550Rz Gold is built around the compact SFX form factor, making it ideal for small form factor (SFF) builds without giving up on high-end capability.
80 PLUS Gold Efficiency
Certified 80 PLUS Gold, the 550Rz offers consistently high efficiency to reduce waste heat and power consumption. It’s rated for continuous power output around the clock at up to 40°C ambient temperature, using a primary Japanese capacitor for long-term reliability in demanding conditions.
FDB Fan with Intelligent Deactivation
Cooling comes courtesy of a 92mm Fluid Dynamic Bearing fan that balances low noise with long lifespan. An intelligent fan stop mode disables the fan entirely during low-load operation, keeping acoustics minimal and prolonging the fan’s operational life.
Modular, Flexible, Easy to Build With
The fully modular cable system is built around SilverStone’s third-gen universal EPS and PCIe connector interface. Flat cables improve flexibility inside tight enclosures, making routing and management cleaner and less restrictive—especially important in SFF builds.
Comprehensive Protection Suite
To safeguard your components and the PSU itself, the 550Rz Gold includes a full array of protection features: over-current, over-power, over-voltage, short-circuit, under-voltage, and over-temperature protections all come standard.
