Redundant 800 W server power supply

The Silverstone GM800-S delivers 1+1 redundant power in a PS/2 mini redundant form factor. Two hot-swappable modules each provide 800 W continuous output at 50 °C for 24-hour operation. It targets rack-mount servers and workstations that cannot tolerate downtime during a module swap.

Japanese capacitors and pull-out handles

Japanese electrolytic capacitors back the single +12 V rail rated at 780 W combined. Active PFC maintains a power factor above 0.9 at full load across 90–264 V input. Pull-out handle bars let technicians replace a module without tools while the system stays online.

51 dBA noise and Cybenetics Silver efficiency

Four 40 mm DC fans cool the unit, producing 51 dBA under load. Overall efficiency sits between 85 % and 87 % with a single module, meeting Cybenetics Silver level. MTBF is rated at 100,000 hours at 0–50 °C operating temperature.
