Poweredge R630, Perc H330 Raid Controller

Hi

I am hoping someone can help.  We were supplied a Poweredge R630 server with no Raid controller.  After multiple issues with the SD Cards we want to get a Hardware Raid controller in the server for running Xencenter.

We were able to buy the PERC H330 Raid controller but have been able to find the cables anywhere for this.  I phoned Dell and they passed me onto their parts suppliers in the UK but failed to phone me back after contacting them 3 times.

Does anyone know where I can get these cables?

Link for the raid card is below.

Thanks in advance for any help
