If some company combined the two of these in an at least moderately functional motherboard, I would have to get a case with a window
I would be disappointed if it lacked sound effects options.

As long as this stays in OEM chunk boxes I'm good. Don't bring that trash down here. Boards are expensive and delicate enough as it is.

Yeah, I'd rather pass on this. I'd like less points of failure on my motherboard and to be able to easily slot in a new PSU versus performing a motherboard RMA. I wonder if Intel will push it onto their later motherboards for all...

not anytime soon. they've gotta figure out how to get less than 200w total package units to not fry first.

i'll definitely spend the corporation's money on it if/when it comes across my board though

I think this will benefit people maxing out their budget on CPU & GPU and cheaping out on PSU & mobo.
Good clean single rail 12 volts with higher efficiency & amperage, then let mobo handle voltage conversion for small load SSD and LEDs. Smaller parts = cheaper too. Gotta make the change for majority of use cases.

We tried this when VRM's were placed on the CPU and it created more problems than it solved, this will be the same. There is no need to place more stress on boards as most boards will have the same worthless components that current rubbish PSU's have, thus the problem won't be solved.

M.2 is 3.3V only:

Spoiler!

Also, 3.3V is used extensively by PCI-E, SATA, USB and various other crap on the mobo. That's why getting rid of it is basically impossible unless you want to change a lot of standards and lose backwards compatibility.



Back to the topic of this ATX12VO thing - instead of going the laptop route, why not just have a 12V only power supply like the one mentioned in the article but instead of the mobo handling DC-DC conversion, have the PSU itself do it? In other words, same way a PicoPSU works, only everything is contained inside a single unit. That way you could just have a standard ATX12V power supply that can be plugged into any PC and less of the hot, failure-prone stuff on the motherboard.

SFF PCs in HP, Dell, and other office computers have been using 12v only PSUs for a while now.

In my personal experience over the last 5 years, we have had maybe five PSU or MB failures out of thousands of deployed PCs. The pros (size, cost, efficiency, complexity) outweigh the cons given how extremely few things use not-12v.

It's more about cutting costs, making desktop PCs same as laptops when it comes to power supplies. Feed them 12 V from PSU or battery, the rest is the same. Low power devices with barely sufficient power parts.
Most laptops and micro desktops use 19.5v. Type-C charging is also 19.5v in the 100w spec. The batteries in the laptops I support range from 7.4v to 11.4v;

Code:
Laptop Model	Battery Type	Watt Hours	Voltage	Dell Part Number
Latitude 5*50	G5M10	51Wh	7.4v	#451-BBLN
Latitude 5*70	NGGX5	47Wh	11.4v	#451-BBUJ
Latitude 5*70	6MT4T	62Wh	7.6v	#451-BBTW
Latitude 5*80	GJKNX	68Wh	7.6v	#451-BBZG
Latitude 5*90	GJKNX	68Wh	7.6v	#451-BBZG
Latitude 7280	F3G33	45Wh	11.1v	#451-BBFX
Latitude 7270	J60J5	55Wh	7.6v	#451-BBSY
Latitude 7280	F3YGT	60Wh	7.6v	#451-BBYE

no one better tell the govt about out of spec processor power consumption. they'll shut the whole hobby down!
Dell's office SFF PCs have been using these PSUs since the 20-series, so about 6 years now. The 10-series before it, which had a standard 24-pin, was the one with all the failures. HP has been on 12v-only for a while as well.

How many MB failures do you get on a regular basis? They are really not all that common, and even when there is a swap it's like 5 minutes of work. They do a good job of making these things repairable.
