Greetings!
Possibly. Do you have any information on the specs or the model number of the Lenovo? Without any of this info, it is really tough to answer your question with any real substance. The motherboard should accept it, but whether the power supply is sufficient for the upgrade is the tough part. Without knowing what you have, it is hard to say if it needs to be upgraded. Take a look at the side of your power supply and let us know what it says about make and model and what the wattage is if possible...That would be a place to start
Hope this helps!
