Up..... E' un paio di giorni che ho rimandato l'ordine perchè sto appeso a questo dubbio.
Nessuno sa dirmi nulla in merito?

googla tu che googlo anch'io...

http://en.wikipedia.org/wiki/ATX#Power_supply

A −5 V output was originally required because it was supplied on the ISA bus, but it became obsolete with the removal of the ISA bus in modern PCs and has been removed in later versions of the ATX standard.

Systems that use an ISA bus require ATX/ATX12V 1.2 or earlier because the ISA bus requires a −5 V power rail unless the board provides a DC to DC converter that supplies −5 V. ATX/ATX12V 1.3 and later prohibit the −5 V rail so power supplies built to these versions are usually unsuitable for ISA systems.
