Dell PowerEdge R520 Power Supplies
The PowerEdge R520 supports up to two (2) AC or DC power supplies with either cabled or hot-swap 1 + 1 redundancy, auto sensing, and auto-switching capabilities. Power supply wattages are 495W and 750W AC and 1100W DC for hot-swap power supplies or a single 550W AC non-redundant cabled power supply. When installing a second power supply in an existing server, the wattage must match the first.
Note that configurations with higher wattage CPUs, a large amount of memory and several hard drives may require higher wattage power supplies.
All power supplies have been tested and pulled from working machines with our 90-day parts replacement warranty.
