PWR-C1-1900WAC-P Description
The PWR-C1-1900WAC-P is a Cisco Catalyst 9300 Series 1900W AC Platinum power supply module for Catalyst 9300, Catalyst 9300L, and Catalyst 9300X switch power-supply bays. It supports high-output PoE power plans and spare PSU replacement for C1 power-supply systems, with 1900W output at 230V nominal input or 1500W output at 115V nominal input. Cisco specifications list 200 to 240 VAC autoranging input for the 1900W condition, 115 to 127 VAC autoranging input for the 1500W condition, -56V DC output ratings, 3.4 lb weight, and a 1.58 x 3.25 x 13.7 in. module size. The C9300LM boundary matters because Cisco documents C9300LM switches with PWR-C6 supplies rather than PWR-C1 modules.

Application Scenarios
PWR-C1-1900WAC-P fits Catalyst 9300 access-switch builds where Cisco’s power tables list the 1900W AC Platinum supply as an upgrade option for larger PoE or UPOE power budgets.
Service stock should reserve this SKU for sites that can match the required AC input range, because the same module has different output limits at 230V nominal input and 115V nominal input.
Mixed Catalyst 9300 warehouses should separate PWR-C1-1900WAC-P from C9300LM supplies, since Cisco documents C9300LM with PWR-C6 modules and excludes the PWR-C1 family from that switch line.

- In a PWR-C1-1900WAC-P vs PWR-C1-1100WAC-P comparison, the decisive difference is output class and input-voltage design: PWR-C1-1900WAC-P supports 1900W at 230V or 1500W at 115V, while PWR-C1-1100WAC-P stays at 1100W.
- The PWR-C1-1900WAC-P difference from PWR-C1-715WAC-P is the higher Platinum AC power class and the narrower voltage conditions attached to the 1900W module.
- For a PWR-C1-1900WAC-P vs PWR-C1-350WAC-P comparison, the current SKU is the high-output C1 PSU, while PWR-C1-350WAC-P is the low-output Platinum supply used where the switch power plan does not require PoE power headroom.
- Buyers comparing which model to choose should start with Cisco’s switch power table, the expected PoE budget, the facility AC feed, and the C9300LM exclusion before approving the PSU line.
Selection Guide
1. Anchor the order to the high-output C1 PSU
Choose PWR-C1-1900WAC-P when the Catalyst 9300, Catalyst 9300L, or Catalyst 9300X BOM requires Cisco’s 1900W AC Platinum C1 power supply rather than a 1100W, 715W, or 350W class module.
2. Verify site voltage before treating it as 1900W
Keep the 1900W output assumption only for a 230V nominal input plan. Move the design review to the 1500W condition when the site uses 115V nominal input.
3. Use lower-wattage Platinum supplies only when the power table
Select PWR-C1-1100WAC-P or PWR-C1-715WAC-P when Cisco’s power-supply requirement table shows that the smaller AC Platinum class satisfies the switch model and PoE target.
4. Keep C9300LM replacements outside the C1 pool
Verify the switch family before finalizing the order because Cisco states that C9300LM switches use PWR-C6 supplies and cannot use the listed PWR-C1 modules.
PoE Power Planning
|
Planning Item |
Cisco-Confirmed Fact |
Quote Check |
|---|---|---|
|
High-output module condition |
PWR-C1-1900WAC-P provides 1900W at 230V nominal input and 1500W at 115V nominal input |
Match the AC feed before using a 1900W power budget in the BOM |
|
UPOE+ model examples |
Cisco lists PWR-C1-1900WAC-P as an upgrade option for C9300X-48HXN, C9300X-24HX, C9300-48H, and C9300-24H power tables |
Confirm the exact switch model before adding the 1900W line |
|
Dual-supply chassis design |
Catalyst 9300 switches support one or two active internal power supplies and can use a blank cover when one PSU is ordered |
Plan the second slot as either a second PSU or the required blank cover |
|
Hot-swap risk |
Removing a PSU can interrupt powered devices if the remaining budget does not support the load |
Check StackPower mode and available power before field replacement |
|
C9300LM exclusion |
Cisco says PWR-C6 power supplies are only for C9300LM and the other PWR-C1 supplies cannot be used with C9300LM |
Keep C9300LM service stock on PWR-C6 parts |
Ordering Checklist
|
Check Area |
What to Confirm |
Why It Matters |
|---|---|---|
|
Exact PID |
PWR-C1-1900WAC-P |
Prevents substitution with a lower-wattage C1 PSU or the separate PWR-C1-1900WHV-T DC module |
|
Switch family |
Catalyst 9300, Catalyst 9300L, or Catalyst 9300X |
Keeps the spare aligned with Cisco’s supported C1 power-supply tables |
|
C9300LM boundary |
C9300LM switches use PWR-C6 supplies instead of PWR-C1 supplies |
Avoids assigning this PSU to the wrong physical power-supply family |
|
AC input condition |
200 to 240 VAC for 1900W output or 115 to 127 VAC for 1500W output |
Prevents overestimating available output when the site feed is 115V |
|
PoE power requirement |
Switch model and PoE budget from Cisco’s Catalyst 9300 power tables |
Ensures the PSU selection supports the planned powered-device load |
|
Second bay contents |
A second power supply or blank cover in the unused slot |
Maintains the slot-population and cooling requirement documented by Cisco |
|
Regional AC cord |
Cisco-listed power cord option for the deployment country and outlet type |
Keeps the high-output PSU line from being ordered without the correct cord plan |
