Tonstep 150W AC Adapter for Lenovo IdeaCentre A700 A730 C305 C320 C540

Compatible Replacement Adapter

This 150W AC adapter replaces the original power supply for Lenovo IdeaCentre A700, A730, C305, C320 and C540 all-in-one desktops. It matches the OEM part numbers PA-1151-11VA, AD8027 and 54Y8803 among others. The unit is a new, brand-new replacement product built to work as genuine parts. A 2.5ft US power cord is included in the package.

Build Integration Requirements

The adapter accepts a wide AC 100-240V, 50-60Hz input from any standard 3-prong wall outlet. It delivers a fixed DC 19.5V 7.7A output through a 6.3mm / 3.0mm barrel connector that fits the listed IdeaCentre models. No internal modification is needed; the charger simply plugs into the existing DC jack on the all-in-one chassis. It frees the system from a failed or missing original power brick.

Thermals Noise and Power Draw

Rated at 150W maximum output, the adapter draws only the power the connected all-in-one requires under normal workloads. The external brick design keeps heat dissipation outside the computer enclosure, helping internal temperatures stay lower. No active cooling fan is present, so operation is silent. The wide input range ensures stable output across varying mains conditions.
