Congress has the ability to overrule the President's veto power with a 2/3 majority vote. Furthermore, Congress has the power to impeach the President, and must confirm the President's choices (i.e. appointment of the Supreme Court, etc.).
Congress checks the Supreme Court in a few ways as well. First of all, it has to confirm the President's appointments of Supreme Court judges. It also has the power, once again, of impeachment, and has the ability to amend the Constitution.

the supreme court (aka the judicial branch)
Both the Legislative (Congress) and the Judicial (Supreme Court), have the power to keep the President's power in check.
The constitution requires that supreme court justices be approved after the president nominates them by "advice and consent". Therefore, the congress can deny the candidate put forth by the president.
The U.S. Supreme Court has the power to declare an act of Congress unconstitutional.
The Supreme Court can check the power of Congress by ruling legislation passed by Congress is unconstitutional. The Supreme Court can do this when they a presented with an opportunity to hear a case which disputes a law. The supreme court's decision is final because it is the highest court in America.
The president checks the supreme court by appointing members of the court.
The first example is how congress checks the President: congress has to approve his cabinet appointments, Supreme Court appointees, and treaties. The President checks congress by having veto power over bills that they have passed.
The President checks the power of the Supreme Court by appointing Supreme Court justices and the Chief Justice (subject to Senate confirmation).
