Which power cord?

I live in the UK I received my new PC a little while ago but have only just been able to get it set up due to some renovations in my room. The problem is this, there was no power lead in the box, for my monitor, an ST2320L. When I checked in the PC box there were two power cords, and now I'm not sure which is for the tower and which is for the monitor. One power cord is a "Honglin Fused" plug and the other is "Vortex."
