Hi,

Because of power costs here, as well as noise, I have to be picky with PSUs. I'm building the following system:
  1. Supermicro X10SDV-7TP4F (Xeon D-1537)
  2. LSI 9300-8i + expander or ext port bracket (or 4e4i), got a 9300-8e at hand I might sell.
  3. 96GB ECC DDR4 ram: 3 x 32GB RDIMMs.
  4. 6 WD Red 8TB disks for ZFS pool (NAS duty).
  5. Assorted SAS SSDs and Intel DC S3500 and S3700s. (4 HGST SAS SSDs, or more, up to 5, and room for 8 of the the other SATA SSDs)
  6. Noctua fans: 80mm and 92mm.
  7. Chenbro 4U case with 5.25 bay backplanes.
  8. Using the two SFP+ slots for 10G P2P, to VM hosts. With DACs.
  9. Populated M.2 and mSATA.
I'm just missing some small components and the PSU itself. The PSUs I was looking into are these:
  • SeaSonic SS-520FL2 520W ATX12V / EPS12V 80 PLUS PLATINUM
  • be quiet! Straight Power 11 450W 450W ATX
  • or power variations of the above, unless something else in a reasonable price of Gold/Platinum efficiency ratings (and quiet) is available in Europe.
I have estimated a power draw of 250-260 for a fully decked out system, tops. I think I might have overestimated this a little.

My other concern is PSU compatibility with the IPMI BMC. I have no idea if consumer PSUs cut the standby power too much, or if the BMC won't be able to stay on during power cycles.

This is happening to me with an Asus iKVM ASMB6 mounted on a Z9PED8-WS board. It means I cannot power cycle the system without losing all access to the BMC. If power is cycled or cut off, the BMC won't get any standby power. I heard this is common for Asus ASMB6's, and it is ridiculous. The PSU is a Corsair HX750 on that system and I had it happening with other PSUs too.

Hopefully someone can sort out my numbers! (and maybe chime in with information on the BMC issue with the other system? I might create a thread for that).

I'm running that board in a UNAS 810A with 8 WD reds on a 350watt flexATX powersupply.
It didnt need the EPS power to function, but I've recently used a CPU 4-pin to 8-pin adapter and plugged it in. It was running fine without it for ~4 months.
I also replaced the CPU heatsink with an actively cooled Supermicro heatsink and put a 40mm noctua fan on the SAS2 heatsink to lower temperatures a bit more. Without it the SAS2 temps were ~80C idle. Now, it maxes at 55C loaded.

No idea what you mean by PSU and IPMI compatibility. Server boards shouldn't have the issues you're have with the Asus card.
Supermicro BMC is pretty good, not as good as Dell iDRAC or HP iLO, but its better than nothing. HTML 5 compatibility helps things out a lot.
Too bad Asrock Rack doesnt have HTML5....as yet.

How did you mount/attach the fan to the SAS2 heatsink?

The replacement for the CPU heatsink seems quite risky, how did that work out for you? Any good alternatives avoiding the warranty-voiding 'surgery'? I think a high static pressure fan on the heatsink, well attached, could cool things down well. Perhaps a 3d printed bracket, similar to the active heatsink one. It seems that could be a drop-in replacement, if Supermicro sells the metal bracket as a replacement part. It looked like a simple clip on bracket last time I checked. Optionally I could build something with aluminum, I guess.

Agreed, we'll see about the active heatsink. I need a friend stateside to forward me homelab goods in exchange for wine cases!

As for the PSU, what do you think about my estimates? I'm at a loss with these low power parts, I used to be content throwing a 500, 750 or 1000 watt PSU and be done with that part of the project.

I had a few xeon D's (1528, 1518) running as compute only with a 200w psu with just the board, 64gb ram and an m.2 ssd.

Used a 350w psu for a 4c-7tpf board with 128gn ram and 8 wd reds. I think the power consumption was around 150w.

Found this picture on my phone. If you look carefully, you can see I have rigged a Noctua 60mm fan on top of the stock passive heatsink. It's held in place with copper wire that I tied to the heatsink screws. This is in a silverstone ds380 case so the motherboard is vertical. There have been no issues with the build so far.

I have Xeon d-1540 with the same 60mm noctua fan in same way that @K D has. Simple cheap and works, not noisy.

PSU is 250w
Has 128gb, 2 x SSD and 4 x 8tb HGST drives, didn’t test power in detail with all the drives but remember it’s idle 50-60w and about 100w medium load.

Neat, thanks for all the input. Truly appreciated. I might look into 3D printing a bracket that snaps on the heatsink, not unlike some vertical airflow coolers. ideally it should be push-pull like LGA 2011 stock server fans used to do. Either way we need the high static pressure models.
