Verify HP part number and power connector

Confirm that the server service tag lists either 446633-001 or 457873-001 before ordering. Check that the system fan header supplies 12 V and can deliver at least 1.88 A per fan slot. Ensure the connector keying matches the motherboard or fan board header used in the target chassis. Buyers needing a different voltage, lower current draw or a non-HP pin-out should select another model.
