They're not too bad, you can get the PicoPSU-120 + 60w Brick for $55 now:

Considering that the PicoPSU-120 goes for $50 alone, that's a great
deal if your system draws less than 60w!
The 80w brick costs $30 and the 110w brick $40, but unfortunately the
110w brick has a small fan in it.

Unfortunately your typical 80+ 300w PSU drops below 80% efficiency
below 50w or so since to meet 80+ standards, they only need to be 80%
efficient at 20% load which is 60w for a 300w PSU. There isn't anyone
who makes a lower power 80+ PSU except for maybe 1 or 2 hard to find
250w units.
PicoPSU is the way to go for a system drawing less than 80w peak for sure.
