9SX8KI Eaton 8000i 8000VA Online (Double-Conversion) UPS/USV

High-Performance Rack/Tower Online UPS featuring double-conversion power conditioning with the 9SX8KI

The 9SX8KI is an Eaton 9SX series rack/tower (RT) online UPS designed to stabilise and protect single-phase enterprise racks where power quality directly impacts uptime. With double-conversion topology and a true sine-wave output, the 9SX8KI continuously regenerates conditioned power to isolate servers, storage, and network equipment from sags, surges, frequency variation, and electrical noise.

Architected for hardwired installations, the 9SX8KI supports clean integration into server rooms, network/telecom closets, and edge infrastructure where fixed I/O and predictable change control are required. Its 8000 VA / 7200 W capacity provides headroom for mixed IT loads, while the specified 12-minute runtime at 50% load helps bridge short interruptions and enables controlled shutdown sequences. The rack/tower chassis supports flexible deployment planning without compromising electrical performance, making the 9SX8KI a practical fit for consolidation or refresh projects that must maintain continuity during upstream instability.

Why Choose the 9SX8KI?

The 9SX8KI delivers a strong density-to-protection ratio for enterprise racks by combining online power conditioning with hardwire reliability, reducing risk from utility disturbances and downstream load interactions. For IT teams, the 9SX8KI supports scalable rollout patterns across standardised single-phase racks, aligning UPS placement with criticality tiers and maintenance windows while maintaining consistent output quality.

Eaton designs the 9SX platform around predictable electrical behaviour, compliance, and serviceable integration into modern data centre standards. The 9SX8KI aligns with IEC/EN 62040 and UL 1778 expectations, supporting controlled deployment in regulated environments that require documented power protection and proven engineering practices.
