You could look at options from Konstantlab https://www.konstantlab.audio/product-category/power-suppliess/ looks like you need to spend the money you will have saved buying all B'ringer modules hehehe.
In seriouslness though, Konstantlab do some great power solutons, it all depends how much your are comfortable spending.
Enjoy your spare HP, don't rush to fill every last space, this is not like filling sticker books. Resist the urge to 'complete' your rack, its never complete so just relax.
