I've wondered this for a little while... why do power supplies come with an auxiliary power connector (also known as legacy atx)? I asked a few fellow computer geeks and they didn't really know what they were for either...one just thought maybe it was for some specialized server components that required a lot of power or something. this is what i'm talking about:
Yeah, some mobo's have these sockets on them. I bought a Compaq mobo for cheap, and it had one of these connectors on it. Mostly, though, they are used for servers.
As qouted from the BIBLE: "For power supllies of 250 watts or more an aux. power connector is recommended to supply the additional 5V and 3.3V the motherboard might needed... ...If your MB doesn't have one it probably wasn't designed to consume a large amount of power."
