A 1U label is the beginning of the fit check
The rack-format description does not define every PSU dimension. Power supply length, mounting features and cable exits can differ between models used in compact rack enclosures. Compare the approved dimensional drawing with the available chassis space.
Installation envelope
Measure available length, width and height, mounting locations and clearance for connectors. Include cable bend radius and the space needed for installation or replacement.
Output rails and connectors
List motherboard, processor, drive and peripheral connections. Check the individual rail limits and cable lengths rather than selecting only by total wattage.
Input and cooling conditions
Confirm the local mains supply, input range, airflow path and documented operating temperature. Leave the manufacturer-required ventilation and service clearances.
1U standalone power supplies
Compare the GW-EPS1U400WB and GW-EPS1U600WB-BD source entries. Confirm chassis length, mounting, cable exits and output connectors.
2U standalone power supplies
Compare GW-EPS2U600W and GW-EPS2U850W. Check the full mechanical drawing and electrical requirements rather than assuming interchangeability from rack height.
Use the actual equipment requirement
The merged category keeps 1U and 2U together for browsing. Installation dimensions, wiring and operating conditions remain model-specific.
Compare the supply configuration
| Option | What it describes | What to confirm |
|---|---|---|
| 1U standalone PSU | A fixed-wired or standalone power unit | Check dimensions, rail capacity and cables |
| Hot-swap module | A removable system power unit | Check the mating interface and supported host |
| 1U redundant assembly | A specified chassis and module configuration | Check the total assembly dimensions and included components |

Information to include in your inquiry
Model & system
Full model and suffix, chassis or equipment model, required output and input supply, dimensions and connector information.
Order & delivery
Quantity, destination, delivery requirement and whether you need modules, a cage, cables or a complete assembly. Ask for the applicable warranty and supply terms.
Frequently asked questions
Will any 1U PSU fit my 1U chassis?
No. Compare the complete dimensions, mounting points and cable exits; the rack height alone is not enough.
Can a 1U standalone PSU be hot-swapped?
Do not assume so. Hot-swap operation requires a product and system specifically designed and documented for it.
What should I send for a replacement check?
Provide the complete old model, label and connector photos, enclosure dimensions and required cable lengths.
Are cables and connectors identical between models?
No. Confirm connector types, pinout, cable lengths and output-rail allocation for the exact model.
