Low power build - 12v power supply (brick) advice

[nfinity]

I'm planing on doing a low power build. Trying to get my hands on a cheaper skylake ITX board with 12V DC in. This will be used mostly as a NAS but also likely a plex server and could have a few more things planned. I would leave it on 24/7 so would like the idle watts to be low as possible.

I saw this article that helped my interest that 10 watts idle was doable yet have more power then a standalone NAS.

My hardware thoughts/plans
CPU - likely a G3900T or G4400T any sklake 35 Watt cpu
RAM - one stick of 8GB ddr4
STORAGE - get a cheap ssd for OS and have a 3TB red drive I'll use. May get another large hard drive for backup to primary 3TB drive.
PSU - ? thinking will be stuck with 12v options, If I get this MB. Thinking 90W power supply with do.

Any advice here? Found this DTK power supply at a good price... are they reliable and efficient?

Biggest focus is efficiently yet not blowing up my hardware at a decent price... I know FSP makes good stuff and decent efficiently. Just haven't found one at a decent price yet...

Just found this FSP power supply at 75W for 12v out...

If 75 watts would be enough...

I dont recall seeing any ITX motherboard with a 12v in like that. Wouldn't that have to be a laptop board???

That said, I'd stick with itx and a normal psu if possible.

Yeah typically I've only seen DC jacks on embedded solutions like this...
https://www.newegg.com/p/1JW-000C-00EZ7

But worry the above one is a bit under powered... plus only 2 full size sata ports.

And found this on ebay...

Please don't out bid me

Where does the power plug into on that board? Looks like a normal 4-pin EPS?

 

[nfinity]

it has a 12v DC power plug on the end. The 4pin 12v plug on the top right corner from my understanding is a secondary power option if you didn't want to use 12v DC connector.

You can find ITX cases with external PSU where you can install small mobo but with standard power connectors. Something like this - https://www.chieftec.eu/en/chassis/itx/compact-series/ix-01b.html There are other brands, I just had this one and installed inside Ryzen 2200G/ASRock X370. It was using 85W PSU like this https://www.chieftec.eu/en/psus/external-psu/cdp-085itx.html

Thin itx, or thin mini itx is what you are looking for. Here's an openbox skylake board at newegg, pair that with a Dell or HP 19V laptop power supply (big pin 7.4X5.0mm power plug).

Woodmack - Thanks, I see those Chiefec power supply only sold in Europe.. The spec sheet is really good but still a bit pricey for me for the ones I saw on the European market.

I ended up going with a Mean Well: GST90A12-P1M 12 Volt 6.67 Amp 80 Watt. Data sheet showed max of 5% ripple, plus 89% efficiently. And I got it for 39 bucks.


TazExtreme3 - That motherboard looked like a great option. I already bought the other board before you commented. Plus the model I got has 3 sata ports, over the others 2. But thanks for throwing it out there.
