Question I dont know where to find a power supply that will fit my new graphics card

[McLucan]

Hello I just bought an MSI RTX 2080ti x Trio but it needs 8-pin x 2, 6-pin x 1 and my current psu only has 2 6+2 pin connectors. What PSU is out there that will have the right connections?

Something with a high enough wattage and quality, likely starts at ~650watts, but dpends on the next question as well. What other parts in the pc? And what budget?
