JMT PCI-E 4.0 x16 1 to 2 Expansion Card Gen3 Split Card PCIe-Bifurcation x16 to x8x8 with 20mm Spaced Slots CPU4P Power Supply Port (SATA)

I am using https://www.amazon.com/dp/B0CVTNLL21?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1 to split the x16 lane. The Sata power connector is coming from my 2nd PSU that is also powering the 2 GPUs connected to it.
