Congress can check the president 's power by stopping funding, the power of the purse is in congress 's hands since they control the budget. The president can veto (or tell congress no) a law if he doesn 't agree but congress can override a veto with a 2/3rd majority. The president can also go by congress with an executive order but congress can override his order with their own law. Now once a law is in place the supreme court can say if that law is unconstitutional but only if a citizen sues the country and brings the case all the way to the supreme court.
