12V-Only Power Supply Spec Launching This Year

[b00merang69]

Intel is reportedly planning to launch the "ATX12VO" specification.

"The current ATX power supply specification has been quite consistent since about 1995 with but a few changes since. However, that might change soon, according to CustomPC. The site reported that Intel will launch its "ATX12VO" design specification, with the "O" standing for "Only," this year.

Initially, the transition will only hit system integrators, so the DIY space will likely continue using the existing 12V ATX design for quite some time.

The idea behind ATX12VO is that it ditches the 3.3V and 5V rails, leaving the power supply's only job as to provide 12V to the system's components. This simplifies the power circuitry design and, thus, lowers the production cost of components."

Yes but in reading it and the comments some day they will all use 12v like some current USB devices and the Mobo can step down for other voltages.

Remember if a device can use 120v and 240v is uses twice the current to run at the lower voltage AFAIR.

So IMO the 12v devices will use less current than 5v.

I am not saying it is a good thing but my last Mobo to rely on the 5v for CPU was an Asus nForce 2 where as other vendors were using the 12v rail, this meant I had very few few good choices for a PSU for OC'ing.
