For QSW, you do not have to prove you have sufficient funds, neither for the CSQ application, nor for the PR application.
For the CSQ you have to fill and sign the "Contract of Financial self-sufficiency". For the PR, there is nothing on the checklist regarding finances.
In general, just follow the instructions and checklists applicable to you and you will be fine.
They "may" ask for proof during landing (I haven't heard about it happening but I guess it's possible). In that case I believe you should be able to show the amount stated in the Contract of Financial self-sufficiency.
HOPE and flyer110 are correct.
