MiniITX board with minimum power consumption?

Question

motherboards

Good day to all.
I want to build a file server at home (serials, movies, bydlokoderskie projects, that is, the computer will work most of the day).
I live outside the city, and our lights are often turned off, so I want to buy a UPS for it (the lights are usually turned off for one and a half to two hours). Therefore, low power consumption is important. The performance of the processor is not much of a concern, the main thing is that its power is enough to keep the system (most likely Ubuntu or Debian), movies / series will be broadcast on Apple TV / iPad via Plex.
Tell me the motherboard (with an integrated processor) with a minimum system power consumption. Thank you.

Answer 1

Raspberry's performance is too low to function properly as a NAS. Even on Habré there was an article about this. There are two and a half options - 1. Do not chase the minimum consumption at the expense of performance. Then it is better to choose Celeron 847 on two cores of the Sandy bridge architecture. 1.5 Look for a compromise on the latest Atoms like 2700/2550. Slightly lower consumption, lower performance. Memory limit (4GB), yes 32 bits if you use a video card. 2.5 Look for a super-economical NAS on ARM with USB support, put pure Linux on it and configure it for yourself (or use what the manufacturer has sewn up). You may win a few watts, but get full disk speed relative to Raspberry, as vendors put in ARM processors that are suitable for the task. Cons - overpayment for the brand, uniqueness.

Answer 2

I also thought about assembling a file server, but after studying the prices, it turned out that the best option in terms of economy and power consumption would be a NAS like WD My Book Live or similar. It costs almost like a bare hdd, but at the same time there is a file server, clients for mobiles and desktops, and in general, if you wish, you can install anything there, because Linux.

Answer 3

Why not use Raspberry pi? An excellent and ideal solution + to assemble a small UPS, for Raspberry it will be enough for 3-4 hours!

Answer 5

Then he asked about miniITX boards. Here: Server config: CPU i3-3250 oem cooler Zalman CNPS2X mother Gigabyte GA-H77TN RTL rev1.1 memory SO-DIMM DDR3 PC-12800 Kingston KVR16S11S8/4 4GB 2pcs SSD Corsair Force GS 128GB sata6gb/s CSSD-F128GBGS-BK HDD 3TB sata6gb/s 3.5" Toshiba DT01ACA300 2pcs (for Raid1)

In the idle state, it consumes approximately 20-25 watts. In the stress test, almost 80 watts (let's say RMS, measured with a laboratory power source). And on average I observe in the region of 35-45 watts (copying files, the operation of light programs)

and

ASUS AT4NM10T-I 3pcs 2.5' HDD 1TB each, two of them are in a software raid, where I store personal photos and videos from home sessions with booze drugs and other information technologies on one I keep movies (it won't be a pity to die) 1pcs SSD 32gb for the system DVB-S2 PCI-E card ubuntu axis, tvheadend, samba, torrents and other tops for left tests

works without turning off, eats about 40-50 watts maximum according to the multimeter

Answer 6

Look at mini-itx boards based on VIA. I'm also thinking of putting together a quiet file washer, I saw one on avito for only 300 rubles, but, alas, without sata.

Answer 7

3250, of course, will be more powerful than Celeron 847, but it will also consume more, see for yourself here, I talked more about platforms. AMD won't suit you - as you can see, the 847 is more powerful and more economical than the Brazos. By the way, to minimize losses, you can power the system from a picoPSU (nano-sized power supply). They say that paired with a laptop power supply unit, the efficiency is higher than that of a conventional power supply unit (since such systems eat little, and the power supply unit has maximum efficiency after 50% power load).
If you are friends with a soldering iron, you can generally power the picoPSU directly from the uninterruptible battery, bypassing the extra DC-AC-DC conversion.
Another idea - you can configure power-states in Linux so that after switching to batteries, the percent sets the minimum multiplier of 16x, which will not allow you to consume the maximum under load. And lower the voltage on the processor in UEFI (but you need to run stress tests to find the required minimum, and then throw in a couple of steps).
Little_CJIOH, VIA had problems with the amount of SATA. Well, I'm sure that there are a lot of mothers with 4 ports, but on Intel / AMD there are such a shaft, even up to 6. And the power is much lower than the Atom, with only slightly better efficiency. Too specific. Now, if you need pico-ITX, that's another matter.
