IIRC, the 'flat' part of [in]efficiency is 20-80%. I got a Seasonic S12
330W for my new setup (M2A-VM HDMI, AMD 64 X2 3600+ Brisbane CPU, 1GB 5300
RAM) and it's well OTT. Idles at 55W, but as I don't need much oomph most
of the time it's on C&Q at 45W, so below 20% level.
It's only with lots of HDs, SLI or Xfire etc. that the PSU and 12V get
hammered so as you say, 250W is OK for most. I went for 330W as being the
lowest good PSU available (other than µATX ones).

If you can do it today, you didn't put off enough yesterday.
