Thank you for the answer.
The cards I'm going to connect are RX 5700 XT, and yes, I have wall meter.

Hello all, I have a question regarding to the usage of CPU/EPS to Dual PCIe cable adapters when the PSU doesn't include enough PCIe cables, but CPU cables (x8 pin).

I have the 'Thermaltake PF1 850W' PSU (2 units), which has a total of 5 EPS ports available, which means you can plug CPU or GPU on any of them. It doesn't have specific ports for CPU and GPUs, like other PSUs.

I already bought a bundle of this kind of cables (link below), like the ones used to connect the GPU and risers, as usual. But to allow the CPU cable to be used for an extra(s) GPU(s) + its risers.
Spec about the cables:
- 16 AWG: PSU cables (CPU and GPU)
- 18 AWG: cpu to dual pcie adapter cable

Those users who are using them, or those who used to use them in the past, do you recommend them to take advantaje of the available (compatible) ports from a PSU? (I already took into consideration the power consumption for each given PSU)

Thank you.
