Power supply for 15 drives (and a component sanity check)

Slowly building a new NAS for home. I sucked it up and paid the shipping for the RSV-L4500 case. I bought 16 of the 6TB drives from https://bitdeals.tech/

Here’s what I have on hand/shipped:

  • Case: Rosewill RSV-L4500
  • HDD: 16x 6TB SAS drives
  • RAID/HBA: Dell H700 raid adapter
  • SAS Cables: 2x SFF-8087 → SFF-8482 cables (so 8 drives ATM)
  • RAM: 32GB (4x 8GB - 2xr4 ECC Registered)
  • PSU: Corsair RM1000X

So I guess future parts to tie everything together and just make it work:

  • EDIT: bought all parts below on 2020/10/21
  • Motherboard: Supermicro X9SCM-F
  • CPU: Xeon e3-1275 v2
  • 2x more 8087->8482 cables
  • HP SAS expander
  • 2x 8087 → 8087 cables (shorter than 15 inches if possible)
  • 3x 120MM fans for the fan wall
  • 2x 80MM fans for the rear of the case
  • CPU Cooler: ARCTIC Alpine 12 CO (because the Freezer 13 is NOT compatible)

EDIT: removed text about previous motherboard
EDIT 2: changed CPU cooler because I bought the wrong one

Am I missing anything else?

Build looks good for a NAS. The Mobo is the weakest (Least upgrade-able) item but with the case and other components if you ever decide to use it for more than a NAS then a simple MOBO/CPU swap and it will be good for many more years. As for PSU power those drives are 17w each so 17wx16=272w the CPU is 84w so 272w+84W=356W Figure an additional 150w for drive spool-up inrush. 356w+150w=506W add in a safety factor of 10-15% so 50w-75w for a total of 556w-582w.
Long story short a 550w-750w PSU will be enough for your system.

thanks for the feedback.

I ended up biting the bullet and bought a motherboard & cpu, and decided to stick with a bit of an overkill CPU, just in case I decide to do more than NAS duty with this build.

A coworker gifted me his 1kw psu (corsair rm1000x, still NIB that he got as a christmas gift last year) so I guess power is a moot point. will update OP
