Modular cabling system Since the peripheral power cables arent hard-wired to the power supply you can connect only the cables you need for your exact configuration of PCI-E cards & storage devices. The rest of the cables stay in the box & not in your PCs case where they can add to the clutter & interfere with airflow.
