Dell SM65CS-01 65W AC Adapter

The Dell SM65CS-01 is a 65W AC adapter built as a direct replacement for HP laptops that use the 4.5mm x 3.0mm blue tip connector. It suits owners of compatible HP Envy, Spectre x360, ProBook, EliteBook, Pavilion and Stream models who need a new power supply.

19.5V 3.33A output with 45W backward compatibility

The adapter delivers 19.5V at 3.33A for 65W output and also supports 45W devices rated at 19.5V 2.31A. A wide 100-240V 50-60Hz input range allows worldwide use without a separate voltage selector.

Questions about this item

Will the 4.5mm x 3.0mm blue tip connector wear out and need replacing?

The blue-tip connector is a standard 4.5mm by 3.0mm barrel plug rated for thousands of insertion cycles; under normal daily use it rarely requires replacement.

What limit appears first when the adapter runs at full 65W output for hours?

Thermal protection engages first — the unit reduces output if internal temperature exceeds its design threshold, preventing sustained overload.

How much heat and fan noise does the SM65CS-01 produce during all-day operation?

It is a fanless design, so it generates zero acoustic noise; the case warms to a safe touch temperature while delivering 19.5V at 3.33A continuously.
