550W Platinum AC Power Supply
The IBM 94Y6668 is a 550 watt internal power supply built for System x servers. It delivers AT-standard power with Platinum-rated efficiency. This unit suits administrators replacing a failed module or adding redundancy to compatible chassis.
Sustained-load efficiency
Platinum certification means the supply maintains high conversion efficiency across a wide load range, not only at peak. Under continuous server workloads the unit runs cooler and draws less mains power than lower-rated alternatives. Stable output protects sensitive server components during extended operation.
Direct replacement for 550W modules
This supply replaces an existing 550 watt Platinum unit in supported IBM System x platforms. The jump is worthwhile when the original module has failed, when adding a second supply for N+1 redundancy, or when upgrading from a lower-efficiency model to reduce operating cost. It does not fit chassis requiring a different form factor or wattage.

Questions about this item
How much heat does the 550W platinum supply put out during continuous use?
A platinum-rated unit runs at high efficiency so less power is wasted as heat even under sustained load.
What server chassis and backplane does the 94Y6668 need to operate?
The supply is built for IBM System x servers that accept this form factor and connector type.
Will the 94Y6668 fit and power an older System x model I already own?
It fits any System x chassis designed for this wattage and connector, matching the original power rating.
