Do you mean the SATA power cables or the data cables? You should be able to connect up to five SATA devices on the TX550m. There should be two cables: one with two SATA power connectors (which will probably arrive already plugged in) and a second one with three connectors (which will probably arrive in the accessories box PCS will have included with your order). You should have plenty of SATA data connectors on the motherboard, even with that SSD installed.
Edit: those fans look great, by the way.
