Then you will get another pop-up window. Make sure you set the "bits per pixel" at 32bits and select "compress" and "pre-multiplied alfa" (See image), then click "save".  The reason for saving the render in *tga format, is to embed the alpha channel within the image file.

Tip – The Image quality.

-Always render your images in high quality. More pixels = higher quality.
-It's always better to scale it down than up.

Photoshop – Deleting the background.

Start up photoshop and open the *tga image you previously saved from 3dmax.
To delete the background colour of your image, go to "channels" and while holding in the "Ctrl" button, click the channel called "Alpha1". The alpha channel should now be selected.

Now invert the selection by going to "select – inverse" and hit the "delete" button on your keyboard.

Now go to the layers palette, make a new layer and place it below the original one and fill it with the background colour pattern of your choice.

So with this simple steps you can export your 3dsmax renders to photoshop and eliminate its background to use the one you desire.
