Dell 8X949 PSU for Legacy Systems

This Dell 8X949 power supply is a new replacement unit for older Dell Dimension, OptiPlex and PowerEdge systems. It provides the 3.3 V, 5 V, 12 V and -12 V rails those platforms require. The single +12 V rail design matches the original specification for the listed desktops and entry servers.

Single Rail Voltage Limits

The unit delivers all power through one +12 V rail, so total 12 V current is shared across every connected component. No independent rail protection exists for CPU versus peripheral connectors. Builders must ensure the combined 12 V draw stays within the supply's rated capacity.
