KHACHIMO 1040W ATX power supply for enterprise

This KHACHIMO unit delivers 1040W of ATX power for WS-C4503 and 4506-E series switches. It carries part number 341-0037-05 B0 and matches the PWR-C45-1000AC specification. The supply is new and tested working for reliable operation in compatible chassis.

Thermals, noise and power draw in normal use

The 1040W rating defines the maximum output available to the switch under load. Normal thermal and acoustic behaviour will follow the host chassis fan curves and airflow design. Power draw scales with the installed line cards and supervisor modules rather than the supply rating alone.

Questions about this item

How do I install the 341-0037-05 B0 unit into a WS-C4503 or 4506-E chassis, and what step is often missed?

Slide the 1040 W supply into the bay until the latch clicks, then tighten the captive thumbscrews; the step often missed is securing both screws so the unit stays seated under vibration.

What maintenance will the PWR-C45-1000AC need later, and when should I plan a replacement?

Vacuum the front intake grill every few months; replace the module if the internal fan grows loud or the switch logs show voltage alarms, typically after several years of continuous operation.
