All 3 HDDs stopped working

[goonsquad36]

I've tried everything under the sun. I've never seen anything like this happen before. I moved my PC into a new case today and among a plethora of other issues that I'm still troubleshooting with the case, all 3 of my hard drives will not spin up now. All 2 TB Seagate drives. The only thing that will Boot is my SSD. when attached to power they do not so much as make a peep. They were working earlier and now none of them. I've hopped into my BIOS and the BIOS shows that all 3 of them aren't even there or being detected AT ALL. Only my SSD shows up. I'm freaking out about this right now and could use some guidance. I've tested all 3 of the drives previously, so I have no idea what is going on here for all 3 of them to suddenly stop working. Here's a list of the things I've tried:
-Hopping into bios
-unplugging it and plugging it in
-switching sata power chords
-Switching SATA slots on my PSU
-Switching SATA slots on my MOBO
-Rescanning in Disk management.

Help pls

Your PSU is fully modular. Did you use original cables from the PSU?

If you used cables from a different PSU model, you may have killed your drives.
