Atom C3000 power consumption

[Marco]

Hi all,

I'm interested in seeing some power consumption figures for the new Atom based Supermicro boards. I've been told that even the A2SDV series should now be generally available, is there anyone owning any of these boards by chance willing to share some power consumption measurements?

Thank you!

Supermicro SYS-5029A-2TN4 Review: A small Intel Atom C3338 NAS

@Patrick has reviewed then, idle between 20 and 30 watts, normal usage and peak is also very low

And yes should be mostly available

The last system I built with the A2SDi-8C+-HLN4F (using the C3758), Seasonic 350W flexATX, two old SATA SSDs and 2x4GB sticks of Crucial ECC RDIMMs idled at about 30W on 230V power with debian installed and usual power management stuff enabled. The A2SDV boards will likely idle at least 5W hotter by dint of the 10Gb PHYs.

Thank you! I would be nice to see other reports for the the 8 cores models, especially the A2SDV-8C-TLN5F.

I just finished editing the Supermicro A2SDi-8C+-HLN4F review with power consumption numbers. Only 14 months after the ask was made.

Was that an update or an old review I can’t find or a new one to be published soon ?

Hi, I asked it in the review comments, but maybe I receive here an answer. You tested 14.1W in idle. I bought it and my setup (1 RAM module, no ethernet connection, one SATA SSD) does not go under 20.2W. I'm using a +/-1W power meter and if I power off I get a similar result as yours (5.2W):

So I do not think its because of an inefficieny of the power supply or the power meter. I don't really think its because you tested 110V (I'm using 230V) so what could be the reason for this huge difference (after all 50% more)?

Supermicro claims that your measurement is wrong as they were not able to reach something under 26W for the 12C model. But as the C2000 Mini ITX boards had a comparable idle consumption between 15 and 17W I really wonder what could be wrong here.

Nope, 230/240v is more efficient.
14w just seems insane low. I would have expected more like 20w at the lowest, I built a vanilla d-1540 system this weekend so will put it on a power meter as a comparison to what @Patrick tested and see if I match same figure

@Evan
So its more a typo and he meant 24.1W? I though 14W would be realistic after the C2750 had a similar result (looks like 16-17W in the chart):

Sadly these Atom boards do not contain a jumper to disable the IPMI chip. I'm sure this would save >5w.

Ok just to update this, vanilla x10sdv-f with 4 x 32gb Samsung ddr4 rdimm, 2 x 256gb pm863 for booting windows. In the Supermicro 721tq case using the standard 250w bronze psu. Just a noctua 60mm fan on the cpu and standard case fan at rear. 220v

My cheaper power meter;
- 3.5w off
- 28w idle (Windows 2016)

System is still on original bios and the 2016 dvd is from 2018 with no patch’s.

Compared to a more expensive (seems can get cheap 8c d-1540 boards right now) c3000 that will save 132kwhr a year or so means for me $30 at most saving.

721tq case won’t fit where I need it :-/ and of course my config would would have more SSD but still it’s pretty efficient.

Saw there was an update to the original article to a 19.1w idle
