My psu uses plastic ties in order to organize the cords, however, there are only two... So, I went to the grocery store and stole twenty or so of the paper/metal ties (http://2.cdn.clearbags.us/media/catalog/product/cache/1/image/9df78eab33525d08d6e5fb8d27136e95/p/a/paper_twist_tie_white.jpg). Can I use these or would the paper set fire or metal conduct something and break something?
