Redundant 800W server power supply

The Silverstone GM800C-PF is a 2U CRPS redundant unit rated for 800W. It fits servers that accept hot-swap CRPS modules and require continuous uptime through N+1 redundancy. The module delivers a single +12V rail rated at 65A with Active PFC above .9 at full load.

Who this suits and who it does not

It suits integrators building 2U rack systems that need hot-swap redundancy and 80 PLUS PLATINUM efficiency between 89% and 91%. It does not suit builders using standard ATX or EPS fixed-mount chassis, nor those needing higher wattage than 800W or a non-redundant form factor.

Deciding specification — 2U CRPS redundant form

The module measures 73.5 x 39 x 185mm without its handle and slides into a compatible CRPS cage. If the target chassis does not accept a 2U CRPS redundant module, the unit cannot be installed regardless of its 800W capacity or Platinum rating.

Questions about this item

How can I verify the GM800C-PF is operating correctly after installation?

The unit provides a 5-pin PMBus connector for monitoring voltage, current and temperature readings through server management software.

What cables and connectors are included with the power supply?

The package includes the redundant module with a 20+4-pin motherboard connector, two 8-pin EPS/ATX 12V connectors, two 8/6-pin PCIe connectors, six SATA connectors and six 4-pin peripheral connectors.

Which capacity should I select for a 2U server needing redundant 800W power?

The GM800C-PF is an 800W redundant module certified 80 PLUS Platinum; choose it when your chassis accepts CRPS 2U form-factor units and requires N+1 redundancy at this wattage.
