Hello guys, I'm new around here.

I am thinking of upgrading my GPU after a long time from a GTX 970 to a RX 6700 XT. Currently my total estimated Wattage is 364W and after upgrading my GPU it increases to 449W.
My current PSU is the "EVGA SuperNOVA 550 G2 550 W 80+ Gold Certified Fully Modular ATX Power Supply". I was wandering if this is enough or should I get another PSU with more Wattage. Total estimated Wattage amounts taken from PCPartPicker.
 
If your system total power draw is 364 with the GTX 970, then it should draw 90W more with the RX 6700 XT... and that is at full power

Could you post your system specs?

By the way, my system estimated wattage from PCPartPicker is 558 W.
I have not be able to get the system to reach 500W at the wall, running all (CPU, GPU, fans and disks) at 100%.

Although it has a 7 year warranty, and it was really good when it came out, I would replace it for a newer 650/750W PSU, just to play it safe. Simply because of the age wear.
Even AMD recommends a 650W unit, and who knows, maybe you want to upgrade to more power hungry components down the line.
Something like this would suffice:
750W
650W
 
Thanks, You've raised some good points there. I was thinking of getting the EVGA Supernova G7 750W but since they aren't in stock I might go for the G6 instead. I've used it before and had a good experience with the Supernova so I wanna try and stick with them again.

EVGA's SuperNova's are beast.
750W should be more than enough for the 6700XT, its a good, silent (under normal operation), reliable and fully modular PSU, great choice!
