Quick PSU install question

[Bambi]

I just bought a corsair tx750 and this is my first psu with an actual fan. Does the fan point upward or downward? The case is a cm690 which has a grill on the bottom where the psu would go. Thank you for the help

Downward.

The fan is an intake fan, so it will blow air into the PSU. Position it so that the fan is at the bottom of the case and drawing in air from the grill in the case floor.
