Need powersupply for 12TB

Lost powersupply and have waited 5 month on WD. Seems hard to get new one(?).
It’s a 12TB G-raid which uses 90V.
Any kind person knows the part number on this item or where to buy?
Thanks in advance!

This is what Google turns up:

12VDC, 5A, centre pin positive

It says 19V - 4.74A on the back.
Its impossible to find a original Powersupply.
