hi folks! a pretty staightforward Q. on atx psu's. i bought a channel well technology 350watt p4 compatible psu some time back. tested it ok on receipt and re-boxed it. now, some eigteen months later, i needed it for a build. this time it was tested with mbm5 ( i'd never heard of the prog. at the time!!) and find that the 3.3v rail runs at just over 3v. any clues on the relative importance of the 3.3v rail please? what is the function in a p4 system? the unit will only be basic. any links for info would be appreciated.
thanks in advance
