You're sick of crawling under your desk to plug and unplug items from your power strip, so now you're going to mount that strip on the wall. Bravo. Just make sure the screws you drill into the wall align perfectly with those on the back of the power strip. If you mess up and fill your wall with too many tiny "test" holes, you're looking at the forfeiture of your security deposit.
On most power strips -- and on mountable housewares like speakers, light strips, and pre-fab shelving -- the holes where the mounting screws slot into the body are on the back. This keeps the screws out of sight, but it also makes it more difficult to visually align the screws when you're doing the actual drilling.
Here's a trick: Use a piece of masking tape and have the holes line up perfectly every time.
First, place a strip of masking tape along the back of your power strip or other item that needs to be mounted. Definitely use masking tape or painter's tape -- it can be removed from the walls without stripping the paint. Use the edge of the power strip as a guide to square up the placement of the tape. Once you have the tape aligned perfectly, the area around the mounting hole is usually raised and you can use your finger to get the tape into all the tiny crevices to help find the exact center of the mounting hole. Use a thumbtack to poke a hole through the center of the mounting hole or a pen to mark the area.
Remove the tape and place it on the wall where you want to mount your power strip. Now you can drill the screws directly into the marked area on the tape. Drill your screws in, remove the tape, and mount.
Aren't you smart?
