Graviton YM-2451C 450W redundant hot-swap server power supply

SKU CH-SDV8-DK2QX

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

  • 450W output powers demanding server workloads
  • Redundant hot-swap design maintains uptime during module replacement
  • Active PFC improves power efficiency and stability
  • Wide 100-264V input supports global deployment
  • SSI-compliant form factor fits standard server chassis

450 W Redundant Hot-Swap Server PSU

The Graviton YM-2451C is a 450 W redundant hot-swap power supply built for server chassis that accept SSI-form-factor modules. It delivers active PFC across a 100-264 V input range and carries an 80 PLUS certification labelled as other certification. The unit is sold new and is non-modular.

Verify SSI R512 G2 Compatibility Before Ordering

Confirm that your server chassis supports the SSI Power R512 G2 form factor and provides the matching hot-swap bay. Check that the system power budget fits within the 450 W rating and that no GPU auxiliary connectors are required, as this model supplies zero 12 V graphics pins. Ensure the AC infrastructure supplies 100-264 V for proper operation.

Suits Admins Replacing Identical Redundant Modules

This supply suits administrators swapping a failed unit in an existing redundant pair or populating an empty bay in a compatible rack. It does not suit builders who need modular cabling, GPU power connectors or a different form factor for a custom chassis. Buyers requiring a higher wattage rating or a different certification tier should look elsewhere.
