If I buy something with insufficient funds on my paypal balance, with the rest of the money be taken from my bank account?

I cannot pass my card for more than $500 a day, and I need to buy something that's $750. I have most of it in a paypal account, but $100 in my bank account. If I buy it and select my paypal balance as payment method, will it simply take the rest from my bank account that's linked?
