Not found Strix-B650E-F motherboard in inventory.
The system with the 2070 is working perfectly, it's been my setup for five years. I planned to add the 4090 to my existing configuration but my spare VGA cables are at my parents' place. My old PSU is a G3 and the new one a G6; after testing the pins with a multimeter, I'm hesitant about swapping cables. I'm going to double-check every VGA cable connection. It seems like the problem might be with the motherboard.
The G3 and G6 models are compatible with the PCIe cables. It appears your motherboard is functioning properly and likely isn’t the problem. Since the 2070 model still requires PCIe power cables, it points more toward a power or PSU issue. I might be mistaken, but I’m leaning toward checking the PSU or cables next.
I notice the details mentioned. The pin arrangements seem inconsistent when compared to your multimeter readings. You used a plastic locking clip for reference, which helped clarify the orientation. You're considering switching to an MSI Tomahawk board, though you're not sure about the PSU yet—your preference is to replace it soon. The purchase will happen today, and you'll proceed from there.
I understand, I made a mistake. It seems like I was in the wrong place. Every plug is built to prevent mistakes unless you force it, so I thought everything was fine. When I figured out the issue, I searched online and most results said it shouldn't be possible. My old G3 PCIe ends have different clip sizes. I’m not sure why EVGA chose this design. I switched to an NZXT c1200 because I prefer a single 12V connector, but I’m wondering if NZXT’s PCIe plugs will match that setup.
