NVIDIA RTX A5000 has a TDP of 230W. It supports PCIe 4 which draws 75W and allows you to put a 8-pin connector which draws 150W. So, 75+150=225W. How they are gonna provide 230W to the GPU?
Does dual-lane GPU draw 75*2 from the PCI lane?
As the power draw from the PCI lane is same for PCIe 3 and 4, does that mean RTX A5000 should work with PCIe 3 slot?
I am asking this because I have a PSU supplying 1300W. The PC supports PCIe 3. But whenever I stress the GPU, the PC shuts down. The PC is a prebuilt Dell Precision Tower 7910. There are two 6-pins and one 8-pin to power 3 GPUs. tried both 8 pin to 8 pin connector and a dual 6 pin to 8 pin connector. But the results are the same.
Here is a video of the power failure when stressing the GPU for rendering:
