Abstract: A computer chassis can include an airflow channel for permitting airflow specifically to cool one or more power supply units (PSUs) within respective power supply receiving space(s). The chassis can include a baffle device positioned between the power supply receiving space and the airflow channel for directing airflow through the PSU into the airflow channel. The airflow channel can be located between first and second spaces of the chassis, each containing computing components. The baffle device can include a cable passthrough that receives a cable that facilitates communication between component(s) in the first space and component(s) in the second space. The baffle device can include one or more ribs that stop the PSU from being fully inserted into the power supply receiving space when the PSU is inserted in an incorrect orientation, thus signaling to the user to remove the PSU and re-insert it in a correct orientation.
