I keep a power strip behind my tv, which is wallmounted. There is only a small amount of space behind the tv, so I need to know if I will be able to squeeze the power plug in behind my tv. From the pictures it looks rather large, but I just want to confirm the measurements with any of you who own it, and would be kind enough to measure it for me. Would be much appreciated!

Thanks.

Edit: for reference, this is the power plug I'm referring to
