Modular power supply units are computer power supply units which can be modified by power connectors. This allows you to modify the power supply to suit your needs and the connectors can be changed depending on the amount of power needed or the type of connector the computer component needs.

Modular power supplies have their benefit compared to other power supply units. Since the cables are detachable, unused power connectors do not need to stay plugged in. This makes it much more practical and aesthetically pleasing since it reduces the clutter. Removable connectors also mean that you reduce the risk of damage to other components, increase visibility of the computer case, increase airflow inside the case as well as reduce costs.

Some modular power supply cables can have a negative affect mainly by increasing electrical resistance between the power supply and hardware. This may in turn influence the performance of the power supply.

When looking to purchase modular power supplies it is important to have an understanding how the device works and what features you require.
