XPS 8930, PowerColor Fighter AMD Radeon RX 6600, no boot

I upgraded the PSU to 850w to support the 500w GPU. Not other upgrades other than RAM. With the new video card unplugged, the computer boots fine from the integrated video.  With the new card plugged in, the HD makes a little noise right when the computer is powered then goes silent, the dell logo appears, and nothing else happens. Any ideas?
