HP Common Slot 750W Platinum Kit

This 750 watt Common Slot power module fits HP server and storage platforms that accept the shared electrical and physical design. It is aimed at data-centre operators who need hot-swap, tool-less replacement without shutting down the rack.

Sustained-load efficiency at 94 percent

At the rated 94 percent efficiency level the unit converts most input power into usable output, so waste heat stays low even when the supply runs continuously near its 750 watt maximum. The Platinum rating means losses remain small across the typical load range found in dense server deployments.

Hot-pluggable design limits thermal impact

Because the module slides in and out while the system runs, airflow paths stay intact and fan speeds do not spike during maintenance. The 100 to 240 volt auto-ranging input lets the same unit operate on any standard data-centre supply without manual switching.

Questions about this item

How much heat does the 750 W Platinum supply add when running continuously?

At up to 96 % efficiency only a small fraction of the 750 W draw becomes waste heat, so the unit stays cooler than lower-rated supplies under the same load.

Which server chassis accepts this Common Slot module without extra parts?

Any HP server or storage system with a Common Slot bay takes the supply directly; the hot-pluggable design needs no cables or adapters.

Will the supply work in an older ProLiant G6 rack that still uses legacy bays?

No — the Common Slot form factor is physically and electrically different from G6 bays, so the module cannot be installed in those systems.
