No this supply isn't modular.
The PSU comes with ALL possible cables attached to it, ready to go.
This has the advantage of ensuring you're not going to need a cable.
The downside is that it's VERY messy and if you're into cable-management, it's
a nightmare storing away all the excess cables you don't need. Bad cable-management
can mean the difference between a good or bad airflow and consequently the
operating temperature of your system.
