(attempt #2) Proposed High-End (ish) Specification: Xeon E5, 8* WD Reds, SuperMicro case+PSU, UPS

[attempt #2]
Hi All, after an earlier post for advice and further reading research, and feedback on my first specification, I have come up with this second attempt, your feedback would be appreciated.

Usage: The NAS is to replace my old ReadyNAS 314, and is to be used as a home-network storage for the family, storing media files (photos, videos, and .MKV Rips), as well as to operate as a Plex server. More options/uses may come online as I get used to the box and my confidence increases :). I'm looking for a box which can sit in the corner, be future-proofed (well as future-proofed as you can be), and run happily for a few years!

Proposed Specification:
CASE: SuperMicro 745TQ [ATX, 8* hot-swap bays, various PSU options, 2* FAN-0082L4, 3* FAN-0074L4]
PSU: Included with above case, can choose from 800W, 920W, 1200W, 1280W [all redundant]
MOBO: SuperMicro X10SRi-F [LGA 2011, 10* SATA 6Gb/s, USB 3.0, Dual Intel Gigabit LAN, IPMI Port, ATX (Need BIOS v2.0+)]
CPU: Intel Xeon E5-1650 [v4 Broadwell, 3.6 GHz, LGA 2011-3, 140W, BX80660E51650V4]
CPU FAN: Cooler Master Hyper 103 Air CPU Cooler
RAM: Samsung 64GB [4* 16GB 288-Pin DDR4 RDIMM ECC 1.2V-2400 (M393A2K40BB1)]
BOOT DRIVE: SanDisk Ultra II [2.5" 240GB SATA III Internal Solid State Drive (SSD) SDSSDHII-240G-G25]
DATA DRIVE: WD Red 8TB [*8, RaidZ2 or RaidZ3 configuration]

To determine the PSU size I've calculated the wattage as follows, using the manufacturers guidance (if found) otherwise the guidance written by @jgreco :

MOBO: No wattage (that I can see) on the specification page, so opting for a high-value, say 300W
CPU: Intel specification states a Thermal Design Power of 140W
CPU FAN: Cooler Master specification states 1.8W (say 2W)
RAM: The RAM specification confuses the hell out of me! So using @jgreco guidance, 4 * 6W = 24W
BOOT: The drive specifications state 85mW active power with 4.5W max write use (say 5W)
DATA: The WD Reds 8TB specification states 1.79 12VDC Amps which equals 21.48W with a 6.4W operational usage = 27.88W (say 28W * 8 = 224W)
CASE FANS: The case fans specification states 0.58 12VDC Amps which equals 6.96W (say 7W * 5 = 35W)

This equates to a total wattage of 730W (*1.25 = 912.5W), however if I add another 64GB of RAM this would increase to 754W (*1.25 = 942.5W), so I think 1200W PSU would be best. I also need a UPS to support this, and am thinking of:

UPS: APC Smart-UPS (2200VA, 1980W, LCD, 230V)

Feedback on the proposed specification as well as my Wattage use calculation would be welcomed.

Thanks.

Yours
Jonathan

Yes, but to be honest still a bit confused over motherboard wattage, should I just be using ~25W then? My research (i.e. google searches) on motherboard usages were always in the 100's, but am I confusing motherboard plain (i.e. just the board) with motherboard loaded (i.e. with board and CPU/RAM fitted)?

I'd say 100W is a very safe estimate for the motherboard including RAM.

Just my opinion, but I believe that with the 800w PSU you should be fine.
I guestimate that after the initial peak while booting and providing power for the disks, this server should idle at 180 watts max. (When the time comes, I would in fact love to see your power consumption both when idling and when heavy transcoding)
This means you can opt for a lower wattage UPS, too
So, in the end you save some cash.

In general, the watts a mainboard takes will be related to the amount of crap on it. A tiny microATX board with only a few chips is likely to take a lot less power than a giant EATX with two CPU sockets, 10G ethernet onboard, an onboard RAID controller, and 24 DIMM slots.

This isn't going to be an exact science for most of you, who lack the equipment to actually measure precise usage, and the strategy I outline in the PSU sizing document involves leaving lots of headroom anyways, so being off on a single component isn't a critical thing. The risk is primarily where you're so far off that you're stressing the PSU during boot. Eventually something may blow, and you don't want that taking your expensive storage and compute components with them. If you make an honest effort, you should come out with a reasonable number. This doesn't guarantee your PSU won't eventually die anyways, but it does mean that it won't be dying because you were so far off that you repeatedly stressed it to death.

According to my research on the X10SRi-F it draws 15.3W, and the source was Supermicro

800W should be sufficient. I would recommend a 1000W if you were planning to grow to 24 bays ;)

8 bays full to start with and future proof on a big system like this? Are you sure you don't want to go for a 16 or 24 bay? If you did, you could add an extra 8 drives later easily. The alternative would be a new case. You're already getting 4U case ;)

And I assume you've seen my X10SRi-F + Xeon E5-1650v4 build

Other than the PSU being overkill and the case being underkill (in a way), eveyrthing seems good :)

Make sure the CPU cooler support LGA2011-3 ILM mounts. Not all do.

And are you aware of how loud Supermicro rackmount servers can be? I know this a tower chassis, but its probably just a rack on its side ;)

Enjoy :)

You might end up getting the latest bios already installed, but it does require a special key if you want to do it easily over ipmi. I am using an E3 xeon and it seems to be good though I am only using a desktop case and 6x4tb WD RED.

EDIT: My system's boot drive is also a Sandisk SSD, but I chose a 120GB model, though I could get away with 32gb or even 60gb.

Thanks for your comments all, looks like I'm on the right track! :)

@Stux , I hadn't seen your post but been reading up on it. It's given me some ideas, I will have a think about the case, as don't really have a cabinet for any rackmounting, but it does look tempting, however in reality I can't see me needing more storage space as only for simple home use.

Think I most probably be going for the 920W PSU and the APC Smart-UPS 1500VA UPS.
