Of course, power supplies come with all the cables you need to get up and running.
It's worth pointing out though that you won't really have much choice in the matter, this is a non-modular power supply which means all the cables are going to be hanging out the back. Might be a tricky job hiding that octopus.
Personally I would recommend adding a bit more to your budget to go for modular, the CX is a solid power supply line but generally, when it comes to budget PSU's, an extra 10 or 20 could nab you an all round better box.
