Ruth's sister 420W internal power cable DL320 G5

SKU CH-TKDN-Y6F6Y

A 420 W internal power supply with active PFC and 80 PLUS Gold efficiency for DL320 G5 servers, delivering +12 V rails at 14 A and 9 A plus 5 V at 18 A

  • Reliable server power with 420 W maximum output
  • Efficient 80 PLUS Gold certification reduces energy waste
  • Broad 100-240 V input suits global racks
  • Active PFC improves power factor for stable delivery
  • Compatible with DL320 G5 using part numbers 432171-001 and 432932-001

DL320 G5 420W server power supply

This 420W unit is built for the DL320 G5 server and carries part numbers 432171-001 and 432932-001. It accepts a wide 100-240V input range and delivers +12V, +5V, +3.3V and +5VSB rails for desktop or server applications. The non-modular design suits direct replacement in compatible chassis. Gold-rated active PFC helps maintain efficient power conversion.

Gold active PFC thermals and noise

Active power factor correction and 80 PLUS Gold certification reduce waste heat during typical operation. The supply draws 7.4A at 100-127V or 3.7A at 200-240V across 50-60Hz mains. Under normal load the unit runs within expected acoustic and thermal limits for a rack-mount server environment. No modular cables means airflow is not obstructed by unused connectors.

Sustained load behaviour on 12V rails

The +12V1 rail provides 14A and +12V2 provides 9A for continuous delivery to processors and drives. Combined with 18A on +5V and 10A on +3.3V the unit supports steady multi-rail demand without short-burst peaks. The 0.5A auxiliary 12V and 3A standby rails maintain management functions during prolonged uptime. Buyers needing higher wattage or redundant modules should verify chassis compatibility before purchase.

Questions about this item

How do I install the PS-6421-1C-ROHS unit in a DL320 G5, and which step is often missed?

Slide the 420W supply into the chassis until the latch clicks, then connect the main 24-pin and 4-pin CPU cables; the step often missed is securing the retention screw that locks the handle in place.

What maintenance or replacement will the PS-6421-1C-ROHS need later?

The internal fan bearings will eventually wear out; plan to replace the whole 420W unit when noise or temperature rise appears, as the non-modular cables prevent a simple fan swap.

Which limit appears first on the PS-6421-1C-ROHS under sustained load?

The +12V2 rail is rated for 9A, so it reaches its ceiling before the +12V1 rail (14A) or the 5V/3.3V rails under heavy multi-core workloads.
