Silverstone GM500-S 500W+500W 80 PLUS Silver mini redundant server power supply

SKU CH-5GEM-4N6RT MPN GM500-S

Delivers 500W+500W continuous output at 50°C with 80 PLUS Silver efficiency in a 174mm deep, hot-swappable 1+1 redundant PS/2 mini form factor

  • Dual 500W modules give 1+1 redundancy
  • 80 PLUS Silver efficiency cuts waste heat
  • Continuous 500W output at 50°C ambient
  • Hot-swappable units with pull-out handle bars
  • Compact 174mm depth fits tight server chassis

Redundant 500W Server Power Supply

The Silverstone GM500-S delivers a 1+1 redundant configuration with two 500W modules in a PS/2 mini form factor. Each unit provides continuous output at 50°C ambient temperature and is rated for 24-hour operation. The 174mm depth allows integration into compact server chassis while the hot-swappable design supports maintenance without downtime.

80 PLUS Silver Efficiency and Build Quality

Certified at 80 PLUS Silver level, the supply reduces wasted heat and lowers electricity consumption during constant use. A single +12V rail design distributes power cleanly to high-demand components. Japanese electrolytic capacitors contribute to long-term reliability under sustained server loads. Pull-out handle bars simplify module insertion and removal.

Suited for Redundant Server Deployments

This unit fits administrators who need fail-safe power in space-constrained racks and value hot-swap capability for continuous uptime. It is not for builders who require higher total wattage, non-redundant desktop ATX form factors, or efficiencies beyond the Silver certification tier.

Questions about this item

Will I need to replace the Japanese electrolytic capacitors during the unit's lifespan?

Japanese electrolytic capacitors are built for long-term reliability and 24/7 operation at 50C, so replacement is not expected under normal use.

Which limit appears first when both 500W modules run continuously at full load?

The 50C continuous operating temperature rating is the primary limit; the units deliver 500W+500W indefinitely within that thermal envelope.

How much heat and noise should I expect from the redundant pair running all day in a 174mm deep chassis?

80 PLUS Silver efficiency reduces wasted heat, while the hot-swappable modules share the load to keep fan speeds lower during sustained 24-hour operation.
