On the wall Find small screws that match the openings on your power strip. Then, select an indistinct portion of nearby drywall and use a drill to install your screws. Slide the power strip over the screws so that it hangs on them to keep the strip off of the ground.
My favorite way is to drive drywall screws through 2 cut pieces of double sided (non sticky) velcro, drive em into the wall, and wrap them around the power strip. Can use an anchor too and more proper screws too if you really want to.
The easiest method, while probably not the cheapest, is called WireMold. Essentially, WireMold is a series of channels, fittings, and boxes that can be taped or screwed to the wall. Wires are ran inside the channel and a cover snaps into the channel to conceal them.

Most power strips come with notches on the back where you can easily slide it onto screws for mounting. In this case, all you have to do is measure the distance between the notches, install the screws that far apart on your desk or wall, and hook it on, tightening the screws after to make sure it's a snug fit.
Run Cables Behind and Underneath Furniture
Simply place your furniture against the wall near outlets and let the cords stay hidden behind and underneath the furniture. This may be the best answer when you're trying to figure out how to hide TV wires.
Utilize Small Clear Clips on the Backs of Furniture
One of the best things about these clips is that they're inconspicuous and stick to almost any surface, from painted walls and tile material to metal and glass. And these clips can be used to hide cords on walls, TV console legs, under the console, and more.
