Thedinotamer Posted April 13, 2024 Posted April 13, 2024 This is my parts list, the plan is to slowly over time expand to 18 HDDs and 2 more SSDs and maybe an Intel NIC far in the future. How many watts will this take in the beginning vs when i'm done (without the NIC since I don't even know if I'll get one) Quote
bagican Posted April 14, 2024 Posted April 14, 2024 Thank you, new link works. I assume min. power consumption when idle (and when HDDs are sleeping) will be ~ 10—20W without additional PCI-e cards. Unfortunately I don't have experience with this motherboard. If you really want very low idle power consumption, I recommend to use: - Pro from Samsung, for example Samsung 980 Pro, or - look at another power supply, see https://www.youtube.com/watch?v=TPSuCbS-4P0 Quote
Kilrah Posted April 14, 2024 Posted April 14, 2024 (edited) Only 3 drives? Skip the LSI card and SAS stuff and connect to motherboard, you'll save 10-15W+ straight. Probably in the 40W range at start without it, about 100 once upgraded... Edited April 14, 2024 by Kilrah Quote
Thedinotamer Posted April 15, 2024 Author Posted April 15, 2024 (edited) @bagican is this better? How much would you say this will draw both with and without the HBA card and expander? @Kilrah i’m going to have more than three eventually, my whole build is optimized to be expandable so I can slowly add more drives up to 18 and also two more SSDs for another cache pool when I need it.

kiwijunglist Posted April 15, 2024 Posted April 15, 2024 Get a z790 that supports 8x sata / 4x NVME and ditch the LSI / SAS stuff. Use larger capacity HDDs eg. 20-24TB Get an i5-12500 / i5-13500 with the 770 gpu Add LSI/SAS when you exceed 8x SATA drives. Should be about 15-20W idle when HDD are asleep. Do you need 650W peak? ... might get better power efficiency at idle if you go for a lower wattage PSU, look at idle efficiency. 1 Quote
