The SilverStone SST-2U850R-GF is a powerful 850W power supply developed for 2U rackmount servers, professional workstations and compact systems that require dependable power delivery. Its 2U Single format and compact 100 x 70 x 190 mm dimensions make it an excellent choice for installations where internal space is limited but high output capacity is essential.

A strong single +12V rail supplies up to 70.8A and the full 850W output, delivering stable power for demanding processors, professional expansion cards and high-performance graphics cards. Its fixed cabling includes three PCIe 6+2-pin connectors and one native 12V-2x6 connector, providing extensive compatibility with modern GPU configurations.

The SST-2U850R-GF features 80 PLUS Gold certification and reaches between 87% and 90% efficiency at loads ranging from 20% to 100%. Active PFC with a power factor above 0.9 at full load helps optimise energy consumption, while the wide 90 to 264V AC input range allows it to operate reliably in professional environments across different regions.

Cooling is handled by a durable 60 mm double ball bearing fan with a minimum noise level of 18 dBA. The power supply also incorporates OCP, OPP, OVP, OTP, UVP and SCP protection systems to safeguard both the unit and connected hardware. With an estimated MTBF of 100,000 hours and support for operating temperatures of up to 50°C, it is prepared for continuous and demanding workloads.
