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.



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


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.
genuine non-user caused failure? I'd say i've had 1 laptop and 1 mini-desktop fail in the year I've been at this new spot. Much lower than it was 5-6 years ago, with lenovo, at my previous employer. n actually, neither of those were even board level failures. both were cooked CPUs.

huh, so our stuff is already doing this? cool.

So basically there would be more failure points on a motherboard if they went with this plan? I guess all it would take is one cheap 3.3V DC-DC converter to die and you would have a non-functional motherboard.

Good PSU's seem pretty robust these days, I haven't had a PSU fail in decades. I have a Rosewill 750 Watt unit right now that I bought used.

Funny story folks,my office actually have two of the dell's with the ATX12VO Specs, the rest are old Vostro 270 (3rd Gen i5). The vostros are still going strong though I have recently replaced the PSU's with seasonic focus modular 550watts and installed new ssd's into the system. Those new Dell with the ATX12VO, they have been problematic. I had to replace both of the PSU in two year's and recently had to get an dedicated GPU as the Intel IGP drivers/GPU was causing the display just to shut down at random. That and i had to go to moddiy just to order the adapter for our old standard ATX PSU to work.

Smart, move more components to the motherboard to cool. It's not like the power supply has a regulated sealed airflow to cool components or anything.

Mobo RMA's are gonna rocket when all those vrms start overheating on systems built by idiots..

READ this thread before starting your first build!!!
ALWAYS power up a Mobo Before installing it! Consider Less than helpful posts as Free Bumps.

If you can't afford to lose it don't mod or OC it.

Can we have daughterboard with VRM components, that we simply plug into new MB? That would work best wouldn't it?

What would be even better is to leave everything as is.
