Will the problems with my new GPU stem from the updated power supply?
I recently received a new 600w power supply, which is semi-modular and comes with its own PSU-GPU cables. The design is quite unique; although it has two 6+2 pin configurations, one of the six pins is missing—the "Sense A" pin (see image below). After some research, I discovered that certain pins are intentionally omitted and this is normal. Further investigation revealed that a GPU won't function without the "Sense" pin, as these pins are crucial for regulating voltage. Without them, the GPU cannot operate.
In context, I own an MSI AMD HD 7790 and it uses a 6-pin connector, leaving the +2 pin out. This included the Ground and Sense B pins. When I attempted to use it, the computer failed to recognize it, even though the fan was running. This prompted me to switch back to my older 300w PSU, which had all the necessary pins.
Now regarding the upcoming RX 5700 XT, it requires 8 + 6 pins. One of the connectors needs an 8-pin setup, which includes a sensory pin. I'm curious whether this GPU can run with only a single sensory pin included.
