You just passed the bar of power by 32 Watts so pushing luck on it. Best bet would be a 1000 Watt but you probably have enough power for 850

maillet In my humble opinion, an 850 watt quality PSU, such as yours, is the perfect match for a 40 series GPU and a Ryzen 7 5800X3D. If you were running a 30-series Nvidia GPU, then I would have recommended a 1,000 watt unit, to deal with the additional transient spikes.​

Question: Is this an existing rig, or one that you're pondering building? If the latter, then I would steer you towards AM5 instead. But otherwise, I think that that PSU is the perfect quality and wattage for your use-case.
