Is this PSU going to be enough for my configuration?

[Zarax]

850W be quiet! Pure Power 12 M (BN344) ATX 3.0

I'm planning to use it with:

- i7 13700k
- 64GB RAM
- RX 6950XT
- 1 SSD
- 1 HDD
- Noctua NHD15
- Corsaid 5000D case with default fan config

Am I safe with 850W or should I consider a 1000W PSU?

Thank you!

1000w ATX 3.0 is not going to be cheap but better safe than sorry I guess.

Thank you!
