Stumped. Tried many PSU calculators online with varying results/recommendations.
My "Be Quiet! Dark Power Pro 11 850 Watts" can only run 1 RX 6000 GPU, not two simultaneously.
I have the following GPUs:
- MSI AMD Radeon RX 6900 XT
- Gigabyte AMD Radeon RX 6800
Ordered a "Phanteks PH-P1200PS 80+ Platinum" 1200 Watts PSU and a "Phanteks PH-P1000PS 80+ Platinum" 1000 Watts PSU.
Planning on choosing the 1000 watts PSU if it works, and returning the 1200 watts PSU. But if necessary, I'll keep the 1200 watts and return the 1000 watts PSU.
BUT now I'm not sure, whether 1200 watts will be enough???????
Any experience with dual RX 6000 series GPUs and the necessary PSU wattage???
PLEASE HELP, thank you!!!
Solved! Go to Solution.
Thank you Excellent!!
For the 6900 XT the difference in wattage between GPU1 and GPU2 = 350 watts.
For the 6800 the baseline recommend PSU wattage = 650 watts.
So with my simple math = 1000 watts recommended.
Again, I'll try the 1000 watt PSU first with rage mode enabled and see how the PSU performs.
If it crashes, then seems the 1200 watt PSU will be more than enough to run the system - thank KF!
