Not if you're going to SLI 2x 2080Tis. Grab a 1000w+ Seasonic Prime, or Corsair HX/AX unit.

9900K w/OC: up to 250w
2080Ti x2: A single 2080Ti will pull between 300-400w[Depending on the model you choose.] at full power.
Add 50w for everything else
Add another 25% on top of the total for some extra headroom.
= 1375w[That's a worst case scenario, everything fully loaded, using 2x Msi Gaming X Trio cards.]
=1125w[Everything loaded, but with 2x 300w cards.]

Now, if you just go with a single 2080Ti:
=750-875w
