Hey Johnklos,

Thank you for your response! I meant 5 volt rather than 5.5 volts - it was a typo - fat finger syndrome here hehe :p I was wondering because I have a CC modded with a 6500 board running of an ATX PSU . I sometimes get intermittend issues such as random bus errors, USB or NIC card sometimes not working properly etc. When I purchased my PSU several years back I was only checking the maximum watts it was rated for (200W) but not how much it can output per rail. Now that I've rechecked the PSU I noticed that the maximum amount of power it can output for 3.3v and 5v combined is just 65W -- not nearly enough I'd think! I realize that most of the later Performa-type Macs predominantly use 5v and 3.3v for voltage input so I used a more beefy ATX PSU which supplies 160W for 5v and 3.3v and these issues seem to be fixed now. So you think 100W+ on 5v and 3.3v should do the trick?
