support for heavy PC?

Just installed a new Synergistic Blue UEF HC pc and have a noticeable difference in the sound presentation from my Classe integrated amp but, the weight of the cord is the issue for me. The cord is 7' long to the outlet and the outlet is 13.5" above the floor level and is inserted into an Oyaide SWO GX+ outlet (the amp resides in a Sanus stand and is 25" H at the IEC input). With the weight of the cord once inserted in the outlet doesn't stay fully inserted unless supported in some way in order to stay as such. Has others found a solution to this type of problem, cable risers aren't tall enough to help me out with this and I don't want to spend a mint but, would like it to be able to have wf acceptance too. Has anyone else run into this type of problem and how were you able to solve it? Non foolish responces would be most helpful.
