I'm using my old 400W MS industrial PSU,I allready spent all my money on a new board and CPU,so there isn't any for a new PSU.I currently the Sapphire HD 5670 graphics card,2.5 GB od RAM,one 160 GB HD,1 DVD/RW and upgrading my PC with AMD Phenom II 955 BE,so can my PSU handle this proccesor or should I wait and save more money for a branded PSU???
