Plein de renseignements, de schemas, de trucs et d'outils software pour tout ce qui concerne les connexions PC.
Les alims PC y sont aussi. (alimentations)

Pour les connecteurs, voir la section 'Motherboard power connecteors'.
On lit aussi, dans la section 'loading':
"According to IBM specifications for the standard 192-watt power supply used in the original AT, a minimum load of 7.0 amps was required at +5v and a minimum of 2.5 amps was required at +12v for the supply to work properly."
....
"Most of the power supplies in use today do not require as much of a load as the original IBM AT power supply. In most cases, a minimum load of 0–0.3 amps at +3.3v, 2.0–4.0 amps at +5v, and 0.5–1.0 amps at +12v is considered acceptable."
D'où la nécessité de la résistance sur le circuit 5V qui n'est pas utilisé dans nos montages, et peut-être une remarque sur la conso minimum sur le 12V.
