I am planning to add more drives to my build since I figured out a way to cram in more hard drive. I am currently at 16 and plan to add 6 more. I know that spin up can consume up to 25W and that my gold rated PSU is 87% efficient, which leaves me with 650W effective power. If all drives spin up at the same time at boot time, that would be a load of 550W. So I have basically 100W to spare for the CPU, motherboard and the 9 fans I have in the case for the boot time only. Once spun up, the drives would consume only 110W so not a big deal and I could then start plotting with the 3900x that consumes up to 145W.
Do you think this could work?
And is anyone else here running a similar setup?
