For those that missed this deal, here's a similar setup for a standard Supermicro (or similar) 1U motherboard build I've had in my watchlist for quite some time (waiting for a price drop):


Doesn't quite qualify for a "Great Deal", not until they lower the prices more as the S-SKUD2 was $280 + tax once you figured in price + shipping, and you got 2x PCIe slots and mobo to boot.

Maybe someone can shoot off a few Offers for a discount on a couple, and report back?

EDIT: There's also this one I've had in my watchlist for a while, waiting on a discount...

Problem with both of these systems is they don't typically fit most racks. You need a extra deep rack to fit them if you plan on using rails. We have racks full of the Quanta ones which required some tweaks and what not. They are also a bit wider than the typical server as well the rails are basically just shelves which cause issues as universal shelves will cause the rack to bow outwards as well once you put around 18 systems into it.

Great systems otherwise.

Update on power usage. So, sticking in a 2nd CPU and another 6x sticks of ram jumps the power usage by 30 watts!

CPU, Memory, Dual-SPF28Add-on CardsPower Usage @ Desktop Idle
1x 3106 CPU, 6x 2133Mhz, Dual SFP28 OCPNone53 W
2x 3106 CPU, 12x 2133Mhz, Dual SFP28 OCPNone84.7 W
2x 3106 CPU, 12x 2133Mhz, Dual SFP28 OCPIntel 905P, M.290.2 W
2x 3106 CPU, 12x 2133Mhz, Dual SFP28 OCPIntel 905P, M.2, SAS2 OCP97.0 W

All power settings below were taken 3 times via my original Kill-a-Watt and the average-ish taken.

Setup:

- BIOS set to defaults, BMC set to defaults.
- Fans set the Default (Quiet) mode
- Bronze 3106 1.7 Ghz (8C/8T)
- 4 GB 2133Mhz DIMMs
- Mellanox dual SFP28 installed, but no transceivers.
- Single PSU installed, 2nd one removed.
- Nothing else connected.

Measurements were taken with Ubuntu 22.04 LTS Desktop at idle with default power savings.

BMC (machine powered off): 9.3 W (idle), 16 W +peak first power on).
POST (no OS C-State power saving): 63 W (idle)

all things considered that's good idle usage.
my old e5 2680 v4 system idles at 77W with only one cpu, four dimms, and no expansion drives or cards.

Not to crap the thread, but that seems high to me if you've got nothing attached/installed. Do you have a chassis with multiple PSUs or huge/fast fans, or something else that pulls a lot of power? One of my NAS started out with an E5-2680 v4 and it idled at a little over 30 watts on TrueNAS with 2xRDIMM, and 13 SSDs. Recently swapped the 2680 for a 2630v4 and idle is down to ~27 watts now.

@eduncan911 , nice write ups on your build and power measurements! Thanks for sharing.

How you measure wattage can be vastly different. The BMC reporting from the onboard PDU of your dual PSUs does not equal actual outlet power usage. Same with Windows software measuring the package usage. Also, UPS with displays that can show watts in real time is also a joke.

I measure at outlet with a Kill-a-Watt meter for the only true way to measure.

This method is always a higher number than ANYTHING else that registers a power reading. Everyone has to remember that: the actual power draw at the wall will be greater as it accounts for power supply in-efficiency at less-optium power draw (idle with no load).

You also have to remember there's a dual-port SFP28 PCIe OCP card (9W) and BMC (9W) using more power as well - that registers at the wall with 18W.

So, comparing Power Usage is a misnomer, unless you state the testing methods and location and all onboard components in use (so they can be disabled).

Therefore, I am stating my test method and readings for others to consume.

--

Edit: as a comparison, I just measured my E5 V3 bare bone server just now. The Supermicro PDU says the system is BIOS idle (no OS power savings) at 43 W. However, the Kill-a-Watt shows 61 W at the wall.

sure, if you want to know what to pay for electricity.
but if you want to know the power draw of the components its untrue.
the difference is also the AC voltage, 115/120 or 230V ?
range of efficiency of most PSU 70..96% depends on load range.
the component load can be from 70 to 90 watt at the same wattage of 100W at the wall on different PSUs.
a valid comparism is imho only possible if both systems use same PSU & AC voltage.

I guess I was pretty ambiguous with that post! :oops: I was actually trying to ask about @EasyRhino 's idle consumption, as both of my E5 v4 systems idle a decent amount lower (mine measured at the wall with a Kill-a-Watt).

I know next to nothing about LGA 3647, so wasn't meaning my post to be a comment on @eduncan911 's findings, other than to appreciate the approach and how thorough and organized they seemed to be.

Sorry for any confustion

Interesting. My motherboard or bios might be a power hog. It's a super micro x10dal-i so it doesn't even have a BMC.

Also your nas might be unusually efficient.

I remembering looking at my older e5 2637 v3 in hwinfo in windows. It didn't idle under 20 or 25w for just the CPU itself.

Almost there (with 10x LFF HDDs).

Will pull the 2nd CPU and extra 6x DIMMs before its finished, and move to a pair of SSDs.

Overtime, I'll rotate in more SATA6-based HDDs - so I can remove the SAS2 OCP card for a very low-powered, disk-suspended backup server. Not bad overall.

So, to continue on this tangent, I have determined that your power usage is freakishly low.

I swapped motherboards on my system to a board that uses an i7 7700K. When nothing is plugged in it idles at under 20 watts. However, when I add a HBA, a 10G Nick, 4x 3.5 drives and 4x ssds, then the idle usage is closer to 80 watts in ESXi with the VMs booted but mostly idle.

Supermicro PDUs (from Supermicro chassis) always gives "lower-than-actual" results, at anything less than 100W. the PDUs, all versions, all tend to be not accurate at all at low power usage. My sources for that statement are the various 7x Supermicro chassis's I've had, and have currently, and their many different PDUs - all against my Kill-a-Watt meter. The PDUs are always running lower - and at < 100 Watts it reads WAAAY lower.

And as I mentioned above, unless you are measuring at the wall with the same device that you are comparing too (e.g. Kill-a-Watt), then "comparing power usage" is just hot air.

Freakish...that's me. Frankly, I was shocked it was that low. Helps that the Fujitsu motherboard doesn't have IPMI. Drives are SATA (Samsung PM843 & Micron 5100) & Intel Series 6 m.2 NVMe, so no high power draw stuff there either.

And as I mentioned above, unless you are measuring at the wall with the same device that you are comparing too (e.g. Kill-a-Watt), then "comparing power usage" is just hot air.
I use a cheap Kill-a-Watt EZ, and usually don't bother with PDU info other than as a historical comparison (i.e. "Gee, this machine is drawing half what it normally does...I wonder if something's wrong?").

I'd assume that if others post values they got using a Kill-a-Watt, and they are on the same mains voltage, then the measurements should be somewhat comparable??

range of efficiency of most PSU 70..96% depends on current load. the required efficiency at 10% load and under must not be tested&granted to get 80 plus(except titanium). this goes down to 70% at some PSU circuit platforms.
the component load can be from 70 to 90 watt at the same wattage of 100W on the wall on different PSUs.
a valid comparism is imho only possible if both systems use same PSU & AC voltage.
Kill-a-Watt's have measure tolerances, use the same KaW-device to remove that issue.

Still impressive/freakish because your whole system idle usage is around what just my 2680v4 idled at by itself.

Incidentally my numbers are from a tp link kasa smart plug. Don't know exactly how precise they are but the numbers check out with other known things like an air conditioner or my desktop computer.

Efficiency and psu design definatly comes into play in the low wattages.

My old silent hosts was whiteboxes with single socket x10 supermicro and e5-2683 v4 when retired.
With just mobo/cpu/ram/120ssd for esxi i got results from 32w to 55w just by using various old psus i had sitting.
(measured on cable from wall with a fluke and same spec other than psu and over same timeframe after booted into esxi and idle)

And as for the reliability of hosts own reading i have a DL380 Gen9 with 12 spinners that say its using 19w :D

the PSU reads DC durrent (sec.side) and that must not be wrong.
As for my example it estimates it from spec and loads, add a few non-hp parts and it goes haywire with comedic results.
(thats the explanation ive gotten from HP previously)
At mid/high loads of just parts intended for the gen its fairly accurate tho.
