I'm very happy with my Seasonic S12 430W. See here for my backend spec
and a useful thread:


My A64 3000+ CPU runs at 1GHz almost all of the time using the
powernow_k8 module, which helps to keep heat (and some electricity
usage) down further (machine is on 24/7). I'd always compare the
efficiency of any PSUs you are interested in and check QuietPC and
SilentPCReview for test results/opinions.
