Recommend a PSU with large 5v rail?

I know very little about power supplies. I have 12 3.5 inch drives plus 2 SSD’s. I have an rm650e, searching shows it’s a single rail and has either 100w or 120w of available 5v power.
Any recommendations on a PSU with more 5v power? Do I even need more power?

Drives are a mix of shucked WD’s and some Ironwolf pros. All 12-14 tb and then a couple of 16tb Toshiba NAS drives.
