HTPC power supply for mobile home vs inverter

[philx1]

Hi all,

Just doing some homework for a mate who's looking for a HTPC (Home
Theater PC)
for his mobile home.

So far haven't found much except this...
http://cgi.ebay.com/PicoPSU-120-120W-12V-DC-DC-Power-Supply-Mini-ITX-HTPC/250576892998

So, my question is - and there is a caveat also in trying to find a
12v DC LCD monitor,
How efficient are 240v AC inverters versus direct DC PSUs?

Just guessing, but I think a HTPC will draw about 2A idle and 6A doing
stuff (I may be wrong though).

Thanks in advance for any thoughts on this.

Cheers, Phil.

I would suggest looking at a lappy

usually they can be driven of a good 12v dc source and Dell as well as
several other dealers used to have 12v screens , check around as I am
sure they can be had

Hey Atec,

Well I probably would look at a lappy, and just today he's bought a
new Mac one, but
the problem I think with that is USB TV dongles and lack of speed.
Maybe also dual DVBT inputs might be a problem with these (if they
exist).
I stand to be corrected of course. Thanks for the reply and idea, much
appreciated.

No idea, but for what it is worth, mini-box make a PS for a Pc mobo that
plugs into a 12V battery.

Voltage?
