The SilverStone GM800-2UG-V2 is an 800W, Cybenetics Gold 1+1 redundant 2U server power supply for compatible rackmount servers that need redundant power and a broad mix of motherboard, CPU, PCIe, SATA, and peripheral connections.
Recommended For
- Operators building or refreshing a 2U rack server who need a hot-swappable 1+1 redundant power supply, so a failed module can be replaced without treating the PSU as a standard single-unit desktop component.
- Small-business or edge-server administrators prioritizing power-supply redundancy in a compatible rack chassis for always-on server workloads, rather than choosing a conventional tower-PC PSU.
- Homelab builders with a rackmount chassis designed for this 2U redundant form factor who value replaceable power modules and can keep server-fan noise away from quiet living or work areas.
