  • Chassis styleDesktop
  • 850 W continuous power for demanding server builds
  • 140 mm depth fits tight rack or desktop spaces
  • 100 % modular cables reduce clutter and improve airflow
  • 80 PLUS Gold efficiency lowers running costs and heat
  • 120 mm fan runs as low as 18 dBA for quiet operation

Compact 850W Server Power Supply

The Silverstone Strider Gold S delivers 850 Watt maximum DC output in a 140mm deep chassis designed for desktop server builds. Its fully modular cabling reduces clutter and simplifies routing in tight enclosures. 80 PLUS Gold certification confirms high efficiency across typical loads. A single +12V rail with 2.5% voltage regulation supports stable 24/7 operation at up to 40°C.

Suited for space-constrained server nodes

Builders fitting high-wattage power into shallow rackmount or pedestal cases benefit from the short depth and modular design. The 120mm fan runs as low as 18dBA for quiet environments. Buyers needing redundant power modules or hot-swap bays should look elsewhere, as this unit is a single fixed supply.

Modular cables and Gold efficiency

100% modular cables let you connect only the leads your build requires, improving airflow in dense layouts. Gold-level efficiency lowers waste heat and operating cost during continuous duty. The package includes multiple PCIe cable sets for multi-GPU compute configurations.

Questions about this item

Does my case need to accept a 140mm deep ATX power supply for this unit to fit?

The power supply has a depth of 140mm and follows the standard ATX form factor, so the case must provide at least that much clearance for the PSU compartment.

Will the single +12V rail deliver stable power to an older graphics card that draws heavily on the 12V line?

The unit uses a class-leading single +12V rail with strict 2.5% voltage regulation and low ripple and noise, which supports consistent delivery to demanding legacy GPUs.

How can I confirm the 120mm fan is running at its quietest after installation?

The fan is rated for a minimum of 18dBA; if the system is idle in a quiet room and the PSU noise is barely audible, the fan is operating at its lowest speed.
