Targeted Replacement Unit

This 300W DC power supply carries model identifiers PSR320-D and YM-1301C and is built for the H3C S7502E platform. It serves administrators who need a direct, tested swap for a failed original unit in that specific chassis. Builders working with other server or workstation platforms cannot use this module.

Tested Thermal Profile

The unit is supplied as a tested, working module rated for 300W continuous output under the H3C S7502E thermal design. Acoustic output and power draw follow the original system specification, so no separate fan curve or efficiency figure is provided for standalone evaluation.

Questions about this item

How do I install the PSR320-D in an H3C S7502E and which step is most often missed?

Slide the unit into the chassis until the latch clicks, then tighten the captive screws; the step most often missed is securing both screws before powering on.

What maintenance will the PSR320-D need later and when should the fan be replaced?

Clean the intake vents every six months and replace the internal fan if bearing noise appears or airflow drops below specification.
