The Udoo x86 features Braswell SoCs, right?
Yes. Celeron N3160 in mine.

OMG... The perpetrators of that mess must have never heard of network design concepts, such as "access", "distribution" and "core".

More here. Just keep scrolling down.
LOL,, Wow... I don't know what to say - that stuff leaves you speechless.
I have a few favorites thou. The "rat in the rack" was good (he was probably their wire tech). I loved what appeared to be a rack mount sized switch, suspended from it's wired connections, in the crawl space. The rat carcass in the server case is a reminder - case covers are a good thing... But I believe the Cat5 nightmare is still the prize winner. That took time, effort, several 1000' reels of Cat5, and a maniacal wire tech to make that happen..

They just have to hire FiberNinja. He will improve everything.
Well, the downside of this approach should be obvious: by using an oversized ATX PSU the system wastes a lot more energy than needed.
I did not say I will use the ATX PSU
The whole idea for me using SBCs where possible is energy efficiency .. so I am open to suggestions..
maybe a modded pico psu ?
maybe a modded pico psu ?
Absolutely not. Those Pico PSU suffer from having DC-DC circuitry to provide the various voltages needed for usual mainboards. With a bunch of normal SBC your best choice is a high quality 5V PSU with adjustable voltage (set to 5.2V) e.g. from Meanwell (low ripple/noise, adjustable voltage). And for 12V it's the same. If you need both voltages (due to your various SBC or the need to power a 3.5" disk) you can opt for 2 PSUs, a dual voltage PSU (I use this thing) or one PSU + buck/boost converter.
And wrt energy efficiency the sizing is important. PSUs operate really inefficient in low load ranges. With a 40W load on a 500W PSU you might see 50W-55W drawn at the wall.
I just ordered a Mean Well RD-65A.
Mean Well RD-65A
Hmm... just 2A on the 12V rail? Might get interesting then with RockPro64, NanoPi M4 and your 3.5" disk... or is it possible to backpower the SATA HAT from the M4 so you only need 5V for board + 88SE9215 and can use the 12V for RockPro64 and the disk's 12V input?
just 2A on the 12V rail?
It is 3A on the 12V rail and 6A on the 5V rail. https://www.mouser.com/ds/2/260/RD-65-SPEC-806447.pdf
Either way, it is borderline. I wanted the RD-85A but I could find a good place to get it in a reasonable amount of time.
I am looking for high efficiency 12V and 5V power supplies now
why?
Is it because of overheating? or electricity bill? Or just a shame to use an oversized one?
Sent from my phone
why?
This power supply is old, inefficient, and hacked up.
Is it because of overheating?
Definitely not. It isn't doing much (about 10% of capacity) and has a 140mm fan cooling it.
or electricity bill?
It has three VMware ESXi servers above it. That probably isn't the problem
Or just a shame to use an oversized one?
More of a challenge to see how low I can get the power use for all these boards.
Vinyl is a good insulator, and really easy to work with.

So the difference between the ATX supply and the second supply is 10 AC watts, with a deduction of (at a guess) 2 watts for a 140mm fan. We'll call it an 8 watt difference. 8 watts per hour, means we're talking about 125 hours to reach a full kilowatt hour. The average price of a kilowatt hour in the US is 13.31 cents. With 24x7 usage, the difference would add up to about 70.08 Kilowatts, per year, for a total cost savings of $9.20 a year.
The best price I found for the RD-65A, with free shipping, was Amazon at $25.78. The cost of the PS is amortized over 2.76 years +/- , depending on actual costs. If the load doesn't change, where more capacity might be needed, the cost of the PS seems to be worthwhile over the long haul.
The average price of a kilowatt hour in the US is 13.31 cents.
Electricity is far too cheap in the US.

Seems ok to me
Electricity is far too cheap in the US.
I'm good with it.
While power efficiency is a "total cost to run" consideration, 13 cents a KW is part of the reason why I don't worry too much about efficiency when it comes to older tech.
The cost difference between equipment that is new and power efficient, versus a used item that can do the job well and be bought for 25% of the new price or even less, can pay for the power difference over 5 years, with money to spare. (@ 13 cents a KW hour)

You misspelled expensive. Our energy costs are artificially inflated by boneheaded socialist policies.
Alles anzeigenI had six small arm and x86 boards in multiple locations and an empty 4U rackmount case. So, I modified a power supply to power all six boards. All of the boards except the atomicpi (has rubber feet on it) are mounted on risers about 20-25mm off the motherboard plate. There are the following boards in the case:
Udoo x86 with 256GB SSD and 30GB SATA M2
AtomicPi
RockPro64
Renegade
NanoPiM4 + SATA hat with 8TB HD and 256GB SSD
RPi2
How do you find the AtomicPi? If you don't mind my asking, what do you plan to use it for? I almost grabbed one when it was on Kickstarter earlier this year. But, as I didn't have a use case already in mind, I decided to pass and instead keep the spousal approval factor a couple points higher.

Kickstarter.
If you don't mind my asking, what do you plan to use it for?
I didn't have a use in mind. It was just cheap and looked interesting.
