Ive purchased 2 of these thinking that they were a good low cost alternative to replacing the power supply. I have numerous good pc power supplies . Both of these talismoons practically caught fire they got so hot. I managed to salvage one but have to keep a fan running on the connector and my 360 frequently locks up. I will be throwing them all away and purchasing a microsoft oem power supply.
