Too disappointed ... I wanted to replace my ATI HD5450 who had blown on my Dell Inspiron 580 ... so I order this graphics card appeared to be similar ... no luck for me on the box it says that it requires a 400W power supply when it is not indicated in the description of the site ... so as I had only one power 300W she could not work ... Thanks However, the effectiveness of Amazon that allowed me to return without problems and repay me ... :)
