The poster is on the side of the box...but it only has the model number of the CPU...but generally the CPU model is correct (of course it refers to the one with a recent production date...)...because the graphics cards of y450 are all the same ’s... Also, check whether the seal of the box is intact! If you have the slightest feeling that it has been opened...don't do it! Because it is very likely that js has been opened and closed before...!
