Ruth's sister YM-2451C 450W redundant hot-swap server power supply

SKU CH-5V7W-YYDZS

A 450 W redundant hot-swap server power supply with active PFC and 100-264 V input

  • 450 W output powers demanding server workloads
  • Redundant hot-swap design keeps systems running during module replacement
  • Active PFC improves power factor and efficiency
  • Wide 100–264 V input suits global rack deployments
  • SSI R512 G2 form factor fits standard server chassis

450W Redundant Hot-Swap Server PSU

This 450 watt server power supply uses an SSI form factor with active PFC and a 100-264 volt input range. It supports redundant hot-swap operation so a failed unit can be replaced without shutting down the system. The non-modular design keeps cabling fixed for dense chassis layouts.

Upgrade from single non-hot-swap units

Moving from a single fixed supply to this redundant hot-swap module adds continuous uptime during maintenance or failure events. The jump is worth it when the chassis accepts SSI R512 G2 modules and the workload cannot tolerate a power-cycle to swap a supply.

Suits rack servers needing 450W redundancy

Operators running compatible SSI bays who need 450 watts per module with hot-swap redundancy will fit this unit directly. Builders using ATX or EPS bays, or systems requiring modular cables or 12 volt GPU connectors, should look at other form factors.

Questions about this item

What chassis form factor does the YM-2451C redundant hot-swap supply fit?

The YM-2451C follows the SSI Power R512 G2 footprint, so it mounts in any server bay designed for that standard redundant form factor.

How is the YM-2451C installed, and what step is often missed?

Slide the unit into the hot-swap bay until the latch clicks; the step often missed is verifying the latch is fully seated so the AC inlet engages the chassis bus.

Which component of the YM-2451C will need replacement first in continuous use?

The internal 12 V cooling fan is the primary wear item; plan to swap it when bearing noise appears, typically after several years of 24/7 operation.
