Seasonic Focus GX 550 for 8 drive NAS?

[Vampirepineapple]

Hello!

I was speccing out my home server build and I have ~100 watts of headroom with the Seasonic Focus GX 550, and that is with 8 drives and 2 ssds.

I currently only have 2 drives and 2 ssds, but I would like to be able to add more later as my needs grow, would this PSU have any trouble powering that many drives?

Build:

Ryzen 7 1700
16gb RAM (2666mhz)
5400RPM Ironwolf pro (x8)
ASUS TUF B450M-PRO S GAMING
1x nvme ssd
1x sata SSD (cache)
GTX 760 (temporary, gonna switch to passively powered down the line)
