# What is the Positive/Reverse Type for Computer Case Extension Cord Power 90 Degree Angle Extension Cord?

The Positive/Negative type of Computer Case Extension Cord Power 90 Degree Angle Extension Cord (SKU: BB051) refers to the orientation of the connector on the extension cord. This determines the direction in which the power cable exits once it is plugged in.

* Positive Side: The connector is angled so the cable routes in one direction (e.g., upward or to the right, depending on installation).
* Reverse Side: The connector is angled the opposite way, allowing the cable to route in the reverse direction, to the PSU fan side.

Choosing the correct type depends on how you want to manage cable routing inside your case. If space is tight or airflow is a concern, select the orientation that best fits your layout.

See the illustration below for a visual comparison of Positive vs. Reverse types.:
