All the Power Strips I buy are $8 each 200 joules surge protection and handle 1825w

The Higher the Joules the more youll pay and better protection you get. 200 joules is plenty per rack that is under 200 watts. My average Surge power strip maxes at 60watts.

Just dont buy off brand, and if you can buy the ones in computer sections as their rated to handle electronics better than whats sold in general stores near extension cords..
