How many watts do you think this parts list will draw?


Recommended Posts

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)

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

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...

@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.

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.
