Common 12V power supply

["Martyn Wendon" <martynwendon@xxxxxxxxxxx>]

Looking around my Node 0 there's about a dozen or so
"wall-wart" type PSUs
powering the likes of routers, switches, cctv cameras, etc.

Since all of these are 12V and have current ratings of between 300mA and 1A
is it possible to replace them all with a single 12V PSU that all the kit
can connect to?

It's got to be more effecient since the heat that the existing PSUs chuck
out must be a huge indication of how much power is wasted and it'll free up
a load of 240V sockets too.


I know that there's different types of PSU (switched, regulated, etc) so
has
anybody done anything similar and is there any off-the-shelf kit that can
do
the job?



Thanks,

Martyn
