The finish is excellent and impressive silence. I replaced the power supply of original HP Pavilion p6-2490ef to install a graphics card more powerful: the power supply is slightly longer so she entered the shoehorn: 5mm longer and c 'was lost. So remember to properly measure the available space, which will route the cables, etc ... The cables are long for big boxes, so they are cumbersome for small boxes. As against this, only installs the cables that are useful, which is a real plus. Great product.
