12v Computer Power Supply?

The only thing 12v is used for in even a 10 year old computer is fans and the hard disk motor. The primary power rails are 5v and 3.3v From that the processor core has several dedicated regulators that supply 1.8v, 2.6v, and other component specific voltages.

So what exactly is your 12v supply accomplishing?

Want to impress me, build me a full ATX power supply that plugs into the mother board. Try and meet those regulation and current requirements with your cowboy engineering. Sure real engineers have mastered that all for $30 these days. But don't let that price fool you into thinking it's junk. Just try to build one from scratch.
