Compatibility and form factor

The Dell D1200E-S0 is a 1400W switching power supply built for Dell PowerEdge C5125, C6100, C6145, C6199 and C6220 series servers. It uses the KJYY0 part number and matches the DPS-1200MB C compatible unit. The unit delivers +12V at 114.17A and +12Vsb at 2.5A for high-density rack deployments.

Who this suits and who it does not

This supply fits administrators replacing a failed unit in the listed PowerEdge chassis or building out compatible rack infrastructure. It requires 200-277V AC input at 50-60Hz, so sites with only 100-120V mains cannot use it without a suitable transformer or PDU. Buyers needing redundant hot-swap modules for other server families should look elsewhere.

Deciding specification

The power input range of 200-277V AC at 50-60Hz is the single specification that determines whether this unit will operate in your facility. Verify your rack power distribution matches this voltage window before ordering.

Questions about this item

How much heat and noise should I expect from the 1400W unit running continuously at 200-277V input?

The supply draws up to 9A at 200-277V 50-60Hz and delivers 1400W; its internal fan speed scales with load and inlet temperature, so sustained full-load operation will produce noticeable airflow noise and exhaust heat typical of a 1U 1400W server PSU.

Which Dell PowerEdge chassis and backplane connectors must already be present for the D1200E-S0 to seat and power on?

It fits Dell PowerEdge C5125, C6100, C6145, C6199 and C6220 series servers that use the DPS-1200MB C form factor and the matching high-current edge connector on the system backplane.

Will the +12Vsb 2.5A rail keep IPMI/BMC alive on a C6100 node while the main 12V rail cycles?

Yes, the standby output provides +12Vsb at 2.5A, which meets the management-controller requirements for the listed PowerEdge C-series nodes during main-power transitions.
