Compatibility
Designed for Dell PowerEdge enterprise servers including XE9680, XE9640, XE8640, the 450-ALMN slides into rear hot-plug power supply bays. The 450-ALMN operates in 1+1 redundant or 2+0 combined modes when paired with a matching power supply of identical wattage. Input voltage compatibility for the 450-ALMN covers standard data center electrical distributions.
How to identify a genuine unit
Genuine Dell 450-ALMN power supplies feature a silver label displaying DP/N 05T92H, input/output voltage and current ratings, 80 PLUS efficiency badges, and Dell regulatory approvals. In iDRAC under Power Monitoring, the 450-ALMN reports real-time wattage draw, input voltage, and thermal status.
Buying used
When evaluating a pre-owned 450-ALMN, inspect the rear blind-mate connector fingers for arcing marks, burns, or physical wear. Confirm that the internal cooling fan on the 450-ALMN spins freely without bearing rattle and that the locking release latch snaps securely into chassis bays. Verify in iDRAC that the 450-ALMN reports normal power sharing without input alerts.
