900W Redundant Server PSU

The Silverstone Technology GM900A-GF is a 900W redundant server power supply built for Micro ATX chassis. It delivers 1+1 ATX redundant configuration with a single +12V rail design. This unit targets administrators who need continuous uptime for critical server workloads.

Cybenetics Gold Efficiency

The supply carries Cybenetics Gold certification for verified efficiency at high load. It sustains 900W output continuously at 50C ambient temperature across a 24 hour cycle. This rating confirms reliable thermal performance inside dense rack environments.

For Always-On Server Racks

Suits operators who require fault-tolerant power for Micro ATX servers running 24 hour workloads. Not suited for builders who need a non-redundant desktop unit or a different form factor. Buyers who want modular cabling options not listed here should look elsewhere.

Questions about this item

How does the 900W rating hold up when the unit is running continuously in a server?

The supply delivers 900W non-stop at 50C ambient, so the headline figure is the real sustained output, not a peak number.

What does Cybenetics Gold certification guarantee for efficiency?

Cybenetics Gold means the unit meets strict efficiency targets across the load range, cutting waste heat and lowering electricity draw compared with uncertified supplies.

Will this redundant module fit a standard ATX server chassis?

Yes, each module uses the ATX form factor, so a 1+1 redundant pair slots into any chassis built for standard ATX power supplies.
