As he is a solder smoke sniffing type.
I'm pottering and one job I have is to mend my mini-itx pc, mythbuntu box.
It was supplied with a 10V laptop "brick" type external adaptor. One day the whole rig failed. Dead.
I have since lost the external adaptor (read as SY02 filed it somewhere), but I do recall it was 10V, but can't remember it's current capability.
No problem as when I use a tinopener on the rig I can see the open frame PSU circuit - model number AD12VC-100-LF.
The properties of this little board are
12V +/- 5%
100W
10A Max.
So firstly I have no frakin clue why PissyWorld supplied it with a 10A brick, but at least that explains why the rig eventually stopped working, ie overcurrent in the external adaptor.
Now, IIRC
100W (Power) / V (12) = I (8.33A)
So I would need a 12V DC PSU say 8.5A?
I have found some online and they strangely mention power factor correction. Why is PFC necessary on a single phase device and should I also be taking this into consideration, or is a 12vDC 8.5A "brick" gonna do the trick?
TIA
