I recently made a deal with the dev... I mean, my uncle Devin, to afford a MSI GeForce RTX 3090 Ti GAMING X TRIO 24G...
and now I'm a bit concerned, because I'm starting to think my PSU may not be powerful enough, it's a
Corsair TX850M 80 plus Gold 850w.

My other components in my systems are:

Motherboard: MSI MAG B550 TOMAHAWK
CPU:AMD Ryzen 9 5900X
NZXT Kraken X53 RGB - Black - CPU water cooler
RAM: Corsair 32GB (2x16GB) DDR4 3600MHz CL16 Vengeance
2 Hard Drives (1 Samsung 870 EVO SATA SSD 500GB and 1 Seagate FireCuda 520 SSD 500GB M.2 NVMe)
4 Case Fans

I'd rather not push my luck and write another contract with my "uncle" to afford a new beefy PSU... but if I have to
I guess I have to... So, please, guys, can I get away with the supply I have you think? :)

This is pretty easy to figure out yourself with a PSU power calculator, they are free online: https://www.newegg.com/tools/power-supply-calculator/

The newegg PSU calculator with components set as you described recommends 900-1200W power supply. A quality 1000W power supply should be enough, I run a 3080 with a overclock 12600KF 3 NVMEs and water cooler + 10 case fans and the PSU shows about 600W max usage under load.

You definitely are underpowered at 850W. Get a proper PSU.

Thank you, yeah I guess I have to buy a new PSU.. really wanted to avoid it but it is what it is... :( Haven't been able to locate a quality 1000w psu in any of the stores I usually buy from (I live in Sweden btw, so the selection here isn't as good as in america usually.), so I've ordered an ASUS ROG Thor 1200W Platinum II and I hope that will be enough, lol.. :)
