I changed the Corsair PSU for a NZXT model, but the problems continued, indicating a deeper problem. By rearranging the CPU and PSU connectors on the power supply, I managed to get the new ATX 3.1 PSU working with my old RX 5700 GPU. However, it would freeze, possibly due to driver issues. To resolve this, I connected the old GPUs’ PCIe cables to the top row of the NZXT CPU and PCIe connectors, then linked the CPU power cable to the bottom row of the PSU. Despite these adjustments, I still couldn’t get the system running smoothly with the 9070XT installed and the new PSU. For verification, I reassembled everything using my BeQuiet! 600, confirmed display functionality, and even launched a game to test rendering. The graphics worked fine, so I’m convinced the 9070XT is operating correctly. I suspect there might be some hardware incompatibility—perhaps my motherboard needs an update or the ASRock board has incompatible pinouts. It’s frustrating because it seems no one else in my situation has faced such difficulties during a PSU upgrade.
This frustration seems focused on a broader problem rather than an individual issue. Are you seeking assistance or simply looking to express your concerns? If help is needed, there are members here ready to assist and verify details. Everyone faces similar challenges occasionally. Please share photos of the setup if you're trying to troubleshoot. For venting, I'll take it personally.
I believe the problem lies in the ATX power specifications. This latest NZXT PSU features a connector design that closely matches the previous model. The motherboard’s 20+4 layout splits into two connectors on the PSU side, while the motherboard itself has only one connector. This cable is unidirectional and cannot be reversed. For the CPU & PCI-E connections, they share just five ports, which seems unusual. The label “CPU” connects to the single 8-pin slot on my board. I’ve tested this connection at every possible angle, but the outcomes remain consistent. The exception was when the CPU was placed at the bottom and the PCIe power for my older GPU was positioned in the top row. Using a 12V-2x6 cable during testing with my 9070XT, it only fits one orientation and location. For peripherals and SATA, I have just two drives, so this cable is plugged into the leftmost port. All previous PSU cables have been removed. I’m careful not to mix wires; these connections are clearly marked and secured. They should be precise, yet here we are. I’ve managed to get the new power supply operational with a GPU under one specific condition: an old RX 5700 connected via two PCIe connectors in the top row, while the CPU uses its 8-pin connector at the bottom left. This setup produced a stable output and video signal. However, the system ran sluggishly, and the Windows login screen would freeze intermittently. It might be driver-related, but that’s not crucial. Overall, whenever this new ATX 3.1 PSU is connected to my system, it fails to boot. When the older PSU is used, it boots normally, even with the newer GPU. I also tried launching a game and successfully getting the new GPU to function. The only concern is that my ASRock B450M Pro4 may not be compatible with ATX 3.1, though this shouldn’t be the case since ATX 3.1 is backward compatible.
