Over non-modular supplies, modular ones have greater flexibility, as you are able to plug in only those cables which are actually useful to your specific configuration with modular power supply units. This reduces the amount of cables in the case and improves airflow which may assist in keeping the components cool, which enhances overall system performance. It also makes the installation and the subsequent cable management process cleaner. On the other hand, modular power supplies do tend to cost more than non-modular ones. All non-modular power supplies have all cables connected individually which is problematic in terms of cable management, but cost efficient for those on a tight budget. Which one to choose depends on your priorities, how much you are willing to pay, and how big of a deal cable management is to you.
