Xtreme Power X90-5S vs Eaton 93PM 400 Frame
A 50–350 kW modular 480V UPS comparison — the hot-swappable, high-density X90-5S against the Eaton 93PM 400 kW frame (3-wire). The X90-5S is a scalable, modular online double-conversion UPS that protects critical data and equipment, available from 50 kW to 350 kW.
Integrated hot-swap modular vs. conventional modular
The Xtreme Power Conversion X90-5S is a scalable, modular online double-conversion 480V UPS that efficiently protects critical data and equipment from power problems, available in capacities from 50 kW to 350 kW.
The Eaton 93PM (400 kW frame, 3-wire) is a modular online double-conversion UPS deployed across data-center support, industrial, and commercial electrical-room environments.
Both platforms provide unity power factor and optional internal redundancy. The key engineering differences are in power-module serviceability, installed footprint, and power density — the considerations compared below.
How the two architectures differ
The Xtreme Power X90-5S is a scalable, modular online double-conversion 480V UPS built from hot-swappable 50 kW and 70 kW power modules, scaling from 50 kW to 350 kW within a single high-density cabinet. Power modules can be added or replaced while the system continues to protect the load.
Because power and battery modules are front-accessible and hot-swappable, capacity expansion and module service do not require transferring the load to unprotected utility power — an architectural difference that affects serviceability, uptime risk, and electrical-room planning.
The Eaton 93PM is a modular, scalable UPS; per the supplied comparison, its power modules are not hot-swappable — the system must be powered down to add or replace a power module, transferring the protected load to utility power during the service window. Footprint and power-density figures below reflect the 400 kW frame.
X90-5S vs Eaton 93PM (400 kW frame, 3-wire)
| Feature | Xtreme Power X90-5S | Eaton 93PM (400 kW frame, 3-wire) | Advantage |
|---|---|---|---|
| Capacity | 50, 70, 100, 150, 200, 210, 250, 280 or 350 kW | 100, 150, 200, 250, 350 or 400 kW | Both platforms provide unity power factor and optional internal redundancy. |
| Modular / scalable design | Modular and scalable | Modular and scalable | Both platforms provide a modular, scalable design. |
| Hot-swappable power modules | Yes — hot-swap power modules | No | X90-5S power modules can be added or replaced at any time without powering the system down. The 93PM must be powered down to add or replace power modules, exposing the load to unprotected utility power. |
| Footprint | 9.2 sq ft — 31.5″W × 42″D × 79″H | 18.7 sq ft — 64″W × 42″D × 74″H | The Eaton 93PM footprint is about 2× larger than the X90-5S at 350 kW. |
| Power density | Up to 38 kW per sq ft | Up to 21.4 kW per sq ft | The X90-5S delivers almost 2× the kW per square foot of the Eaton 93PM. |
| Warranty | 2 years on-site with factory start-up | 1 year on-site with factory start-up | Xtreme Power includes factory start-up and a 2-year parts & labor warranty; the 93PM includes start-up and a 1-year parts & labor warranty. |

Where the X90-5S leads
- No-downtime module service. Power modules are hot-swappable — add capacity or replace a module while the load stays protected, with no transfer to unprotected utility power.
- Roughly half the footprint. 9.2 sq ft at 350 kW versus 18.7 sq ft for the 400 kW 93PM frame — about 2× smaller.
- Almost 2× the power density. Up to 38 kW per square foot versus up to 21.4 kW per square foot.
- Longer standard coverage. 2-year on-site parts & labor warranty with factory start-up, versus 1 year.

Detailed electrical specifications vary by configuration.
Where planners evaluate the X90-5S
Infrastructure planners frequently evaluate the X90-5S where:
- Electrical-room modernization where installed footprint and power density are constrained
- Deployments that cannot transfer the load to utility power for module expansion or service
- Phased capacity growth from 50 kW toward 350 kW within a single cabinet
- Projects standardizing on a longer parts & labor warranty with factory start-up
