These are the Xecuter double shielded pro CPU RST cables for the Xbox 360 Slim consoles. These cables come prepared and ready to use, they have a ground wire that is already pre-soldered into place on the cables shielding, then stripped and heat shrink wrapped. The main cable line itself has 50Ohm impendence, the shielding is 90db double shield, multi-ply bonded outer foil conductor and aluminium foil inner conductor. These are the cables that Xecuter recommend to use for the CPU RST line, they can be handy for those consoles giving some trouble with boot times. Note these cables are intended to be used only in conjunction with the Slim Post QSB boards, if you use them directly on the motherboard you run the risk of pulling the pad off the board. If you are having trouble with a console and want to try a professionally made up double shielded cable then give these a try.
