A Next Generation Power Supply without 3.3V OR 5V Rails. Can't wait to see inside one of these units in a teardown!

"The pure-12 V PSU has only two domains: +12V and +12 Vsb. What this means is a goodbye to the bulky 24-pin ATX power connector. The PSU only feeds 12 V to your motherboard, which uses onboard VRM and DC-to-DC switching to put out the lower voltage domains, including power for your SATA storage devices. The 24-pin connector is effectively reduced to a new 10-pin connector that only has 12 V and 12 Vsb cabling. Other cables include 8-pin EPS connectors for your CPU VRM, and 6+2 pin PCIe connectors for your graphics cards. EPS and PCIe power are purely 12 V-based standards already. The 5-pin connector is less than half as thick as your 24-pin connector, and 2 pins wider than an EPS connector. Some of the more premium PSUs may user thicker gauge wires for this connector."

I'm curious what the XOC crowd thinks of this. If the VRMs on the mobo really are superior, I feel like it would make the most difference to those guys. Do they normally run 12V-only supplies?

** edit **
Oh, I derped. It's for an upcoming board spec not for today's desktop boards.

So PSU prices should decrease and mobo prices will increase?

Since the additional VRM components will simplify PSU design and move onto the MB design.

I use dual psus for basically this role and it would save me having to worry about loading 5v and 3v rails..
That said 12v psus are nothing new.

Why do we even need -12v? In thought that was used excursively for ancient RS232 serial communications?
