You made a mistake and are looking for assistance!
I received my new GPU and PSU two weeks ago. The setup included a Ventus 3x Rtx 5080 and a BeQuiet Dark Power 1000W. All other components had been functioning since the end of December. My PC has performed well over the past two weeks with the new graphics card. However, during a game called Delta Force, my fuse tripped. I checked the area for obvious damage but found nothing. I replaced the fuse and noticed a loud bang from my room, along with a humming noise from the fuse box. After removing the fuse, smoke appeared near the power supply, prompting me to open the room and ventilate it. Frustrated, I contacted support, who is still awaiting a response. While waiting, I realized I had two power supplies—one with 2 outputs and another with 1 8-pin PCIe port. To test, I used the larger 720W supply with the adapter cable for my 5080, added two PCIe ports via an adapter, and connected the smaller one to my older PC. When I tried to boot up, the smaller supply emitted a loud noise, so I activated the emergency stop switch on the multiple socket I had set up for this experiment. After removing the smaller supply and the 5080, I reinstalled the original GPU, and everything functioned properly again. Now I’m wondering—was it a faulty graphics card or just a mistake during installation?
Connect the GPU using both power cables and leave them unplugged. If the PC remains inactive when you press the power button, the GPU is likely dead. When fans spin and the system shows effort, things may be stabilizing. Your Ax1600i experienced a direct 12V short but didn’t fail catastrophically. I’m considering upgrading to a higher-quality PSU from American Power for more reliable testing. It seems that tested PSUs from reputable brands often handle higher voltages safely, though they can still pose risks if misused.
Pay close attention to this guide—PCIe and EPS connectors can look similar but serve different purposes. Understanding these differences is key to avoiding confusion. For more details, see the reference image here: https://i.sstatic.net/CUjEc.png
ok well that isnt what i suggested. if you boot the pc with the 5080 as i said with the power leads unplugged, if there is a direct 12v short in the gpu causing the problems, then the pc wont turn on because it will be still shorting the motherboard, but motherboards are fault tolerant to this and nothing will happen.
Did you just provide power only to the GPU? Yes, I did that when using the two power supplies, since I powered the GPU first and then activated the RGB lights and fans.
