Power supply for PR4100

Hi, I have been the owner of a PR4100 for a few years and my power supply has died. My issue is that I have been unable to source a replacement in the uk as WD do not supply replacement power packs. Does anyone have any idea where I can reliably source one from please?

Thanks Dom

Check out the power output rating on the current one you have then search the web for something with the same rating… might even be cheaper!
