DELL 0YNWT 460W 80 Plus Gold Server Power Supply Reverse Airflow

SKU CH-B83A-G3R23

A 460 W 80 Plus Gold hot-plug server PSU with reverse airflow cooling for Dell Networking S4048-ON switches

  • 460 W output powers demanding network environments
  • 80 Plus Gold certification reduces energy waste
  • Reverse airflow fan optimises data-centre cooling
  • Hot-plug design allows replacement without downtime
  • Compatible with Dell Networking S4048-ON switches

Dell 0YNWT 460W PSU

This Dell 0YNWT unit is a 460-watt hot-plug server power supply with 80 Plus Gold efficiency and reverse airflow cooling. It is built for the Dell Networking S4048-ON switch and other compatible enterprise systems. The compact design fits standard server bays and supports quick replacement without downtime.

Ideal for switch maintenance

Network engineers maintaining Dell S4048-ON infrastructure will value the hot-plug capability and Gold-rated efficiency. The reverse airflow fan matches data-centre rack layouts that exhaust heat toward the cold aisle. Buyers needing a redundant PSU for a different switch model or a non-Dell chassis should verify pin-out and airflow direction first.

AC 200240V input only

The power supply accepts AC 200240V input voltage, which determines where it can be deployed. Facilities wired for lower-voltage distribution cannot use this unit without upstream transformation. Confirm your rack power distribution matches this requirement before ordering.

Questions about this item

How often will the reverse-airflow fan need cleaning or replacement in a rack?

The 80 Plus Gold unit runs cooler than lower-rated supplies, so dust build-up on the reverse-airflow fan is slower; plan a visual check during each scheduled rack maintenance window.

What hits its limit first when the supply runs at full 460 W output for hours?

Continuous 460 W load pushes the AC 200240 V input and the reverse-airflow cooling to their thermal ceiling before the 80 Plus Gold efficiency curve rolls off.

How loud and hot does the reverse-airflow fan get during 24/7 operation?

The reverse-airflow design exhausts heat toward the cold aisle, keeping inlet temperatures lower; fan speed ramps with load but stays within Dell S4048-ON acoustic specs.
