XPS 8900 Psu dell psu hk560-18fp Upgrade

Hello, I currently have a dell psu  hk560-18fp model Psu in my desktop XPS 8900. I am running it with a 1060 gtx. I currently have a 1070Ti coming in the mail, however, this power supply is currently not powerful enough for this PSU. I would like to upgrade my power supply to something (min500w+) (preferred 600w). could you guys help me find one that is compatible with my system. motherboard, case, ect.
