The PC is in very good , look almost brand new.  Power supply is Lenovo brand.  Very cheap mouse and keyboard, I am using my own keyboard and mouse.  No problem activating the Window 10, I don't even need to enter the product key.  WIFI work fine.  The SSD really help the performance, only took about 15 second to finish boot up.  Don't like Win 10, I wish I could buy this PC with Win 7.  Bought this PC from Tekrefurb, they really packed it and  ship out on time, I think they have the best price.
