Direct replacement for PowerEdge 850 860 R200

This 345 W server power supply matches part numbers RH744 0RH744 CN-0RH744 and model PS-5341-1DS-ROHS. It fits the listed Dell PowerEdge chassis without modification. The unit is new and ready for immediate installation in compatible systems.

Thermals noise and power draw

The PSU accepts 100-240 V input at 5.5 A across 47-63 Hz. Output rails deliver +12 V at 22 A +3.3 V at 10 A +5 V at 23 A +3.3 VSB at 4.25 A and -12 V at 0.3 A. Standard server cooling handles thermal load under normal operation.

Upgrade from failed or lower-wattage units

Replaces a faulty original supply or any lower-output unit that shares the same form factor and pinout. The jump is worth it when the existing PSU cannot sustain the combined rail currents listed above. Builders needing redundant or higher-capacity power should verify chassis support before purchasing.

Questions about this item

How do I install the PS-5341-1DS-ROHS in a PowerEdge 850 and what step is often missed?

Slide the PS-5341-1DS-ROHS into the chassis until the latch clicks, then verify the 100-240V~/5.5A 47-63Hz input label matches your mains supply — the click is the step people skip.

What maintenance will the RH744 unit need over time?

Clean the intake vents every few months to keep airflow over the +12V---22A, +3.3V---10A, +5V---23A, +3VSB---4.25A, -12V---0.3A rails; replace the unit if fan noise rises or voltages drift.

Which limit appears first when the 345W supply runs continuously at full load?

The +12V---22A rail hits its 22A ceiling before the 345W total, so sustained draws above 22A on 12V will trigger protection first.
