I assembled a new PC but found no display at all. The problem appears to be with the GPU or its power supply because: -The HP GTX 1650 functions properly in this machine. -It doesn’t work on another system too (despite identical PSU and power connection). -Both systems start up normally into Windows 10 Pro 64-bit, temperatures and fan speeds are normal. The GPU’s LEDs illuminate but no signal reaches the monitor. I tested multiple monitors and cables; one monitor accepts all connectors yet still shows nothing. I suspect a misconnection with the power cable—though the standard method is: connect the 12-pin to the card, then the three 8-pin PCIe slots from the GPU’s cable into the PSU. The GPU behaves identically (lights on, no output) without any power cable. The included cable has additional connectors but they don’t fit the PSU clearly. The computers in use are: -Gigabyte Z790 AORUS ELITE AX ATX LGA1700 (version 1.x, BIOS FHc) -Intel Core i9-14900KF -Noctua NH-D15 with 2 fans -Crucial CT16G48C40U5 16 GB DDR5-4800 CL40 (temporary, to be replaced later) -Samsung 980 Pro 1TB -MSI SUPRIM X GeForce RTX 4070 Ti -Corsair RM1000x (2021) 1000W 80+ Gold Certified Fully Modular ATX PSU -ASRock H610M-HVS Micro ATX LGA1700 (BIOS 13.04) -i5-12400F -Stock fan of the 12400F -Silicon Power XPOWER Turbine 16 GB DDR4-3200 CL16 -Samsung 870 Evo 1TB -GTX 1650 from a HP Pavilion -Corsair RM1000x (2021) 1000W 80+ Gold Certified Fully Modular ATX PSU (now used instead of an older cheap one)
No, connect the PCIe power cable from the card to the PSU's actual PCIe power cables.
Are you connecting three separate cables from the power supply to the GPU? Or are you using one or two daisy-chained cables? The 40 series cards require a 16-pin socket (12VHPWR), which has been a significant issue since its introduction. Since your PSU doesn’t support 12VHPWR, you must connect it to the 3*8 pin adapter. When plugging in the cable, ensure it’s fully inserted—there’s little indication when it’s completely in place. Additionally, you’ll need three distinct cables from your PSU to reach the 12VHPWR to the adapter. If you’re unsure, please share photos.
At the power supply unit, you need to connect three PCI-E 6+2 or 8-pin cables (as shown in the image) that came with your PSU into the appropriate slots on the PSU. Check both ends of each cable—one side indicates it's for the PSU, the other for the GPU. Ensure the cables click to confirm they're properly inserted. Then link the PCIe-connected end of all three cables to the "3*PCI-E 8 pin to 12VHPWR (16 pin)" connector provided with your GPU. Finally, insert the 12VHPWR (16 pin) into the GPU. Once finished, share photos of the PSU back panel and the connectors near the GPU.
I successfully got it working! After reviewing the connections, I noticed one of the three 2+6 pin plugs (linked to "3*PCI-E 8 pin to 12VHPWR (16 pin)") was missing the "2" section, only having the "6" side. I wasn’t sure how I overlooked it, but I did catch it. Otherwise, everything was plugged in correctly. My mistake came from assuming the entire cable—including the PSU’s wires—was just the GPU cable, when in fact the PSU part was included as well. Thanks for your assistance!
Great news it functions. I’d recommend adding a bit more power to the 12VHPWR connection for the GPU just in case. Just yesterday I noticed someone mentioning “melted connector p*rn” on the forum, probably because they didn’t connect it securely enough.
