Building New System - AMD Ryzen 9 7900X, AMD 6950XT - Is My Three Year Old Seasonic Prime Gold 75-W Going To Be Enough?

[SlapShot]

As the title says. My three-year-old Seasonic Prime Gold was just about the top rated power supply when I purchased it three years ago. I've read several recent articles reviewing 7900 XT's saying that a minimum of a top quality 850 is needed. Am I okay using what I have in my new system?

7900xt power usage is typical to rx 6900xt based on TPU review: https://www.techpowerup.com/review/amd-radeon-rx-7900-xt/37.html
In guru3d, they recommended 650w minimum for whole system, and 7900xt used a lot lower than your 6950xt: https://www.guru3d.com/articles_pages/amd_radeon_rx_7900_xt_review,6.html

So your prime 750w gold should be able to handle the upgrade, even if you upgrade to 7900xtx or rtx 4080.

75W is definitely not enough
