Intel talks future PC power
video description
So, is this where Intel wants to innovate today? The space between 0W and 15W to save you less than half of that power? In practice, there are only 2 things that change, and only one is relevant:
1) Less wires going to the MB (this is good.
2) Moves the step-down voltage stages from the PSU to the MB. This makes the PSU a bit more efficient and the MB itself a little less efficient. Add them together and there is NO REAL CHANGE.
Let me repeat that for you: the inefficiency is moved from the PSU to the MB. The MB manufacturers will cheap out on MOSFETS to keep the previous prices, while the PSU manufacturers will keep the previous prices justifying them as R&D costs.
Yes, I do want a new standard, but what I wish for is a single fat 12V rail from the PSU to the MB only, then stronger power 12V rails integrated in all of the ports and connectors. For SATA drives is simple to produce adapters that would ease the transition and make products cross-compatible, but PCIe remains an issue. I don't want anymore separate cables for power and data (SATA, not extra power cables (VGA cards, soundcards, etc) And, yes, before anyone asks, I do have an Asus Xonar D2X soundcard that takes a floppy power connector.

The -extra- sata/peripheral connectors has qualmed my only other hand wringing.
Only last worry is less practical, I worry with power stuff moving to the board - whether it survives a power surge/failure/anything depends on the board being able to survive outright rather than -how good is you power supply- and the -mode of failure-. Like bad boards will prolly kick the bucket quicker then bad powersupplies in the same situations - but thats just a gut thing.

Great idea to lower the electricity bill. My computer is idling -10h daily, sometimes I forgot to turn it off. In my case at least 15kWh savings per month can be achieved by the 12VO, which then is saves around 30 usd / year looking at current electricity price in my area. 5 years -> premium PSU for free. I'm really looking forward for this and waiting with building next rig until 12VO mobos/PSUs will be available.

Using his own charts, with best case at 20W, if you left your PC running 24/7 for an entire YEAR, you'd save 8$ at current US average price/kWh. I know there might be gains if everyone converts, but how about the cost of buying new equipment to run? Not to mention how long it'll take for mb vendors to get a good implementation of their own 3. 3V/5V converters. Now that is some grade-A fake innovation.

What about a standard for PSU output connectors on PSUs?
Like one type for board power (incl. 12VSB) and one type for PCIe/extra board power.
Then board manufactures could supply cables if they for some reason want another connector type (like Nvidia. Maybe even soldered cables on the boards?

This is a good interview. The ATX12VO spec is a subtle but important change to the desktop PC market. In particular it's good for the environment.
I wonder if the ATX motherboard spec will se a change i the future. There's not been any attempts of change since BTX failed.

Well. he says transformers, In a good PSU there should be only one or no transformers! Its all done by switchmode step up/down. Removing the -12, 5, 3. 3 volt should not do anything meaningfull to efficency. The only real reason to do atx12vo is clutter in your case.

i wish i could ask about them changing the ten to a twelve pin that nvidia. Also YES sata data and power one cable DO IT. I always wanted that. will this allow for smaller power supplies cause i really want to built a mini itx system and minimize the size

My issue with 12VO is that it will only increase costs to the avg consumer, PSU costs won't go down, but motherboard costs will be pushed up due to the fact that you need those 3V and 5V lines on them.

I never turn off the computer. Or better, every two weeks or so when RAM use starts to act real strange. That's a thing Windows still hasn't managed to do and that's managing RAM use properly.
