How to connect gpu to psu, cant load windows

[vitucis89]

Hello. Bought a new video card gtx 1060. Previously had gtx 660. The old card was connected to psu with 2x pci e cables, but the new card needs only 1 pci e cable. After pluging in one of the pcie cables my pc wont load.
What is the right way to connect the gpu to psu? Please help, if possible provide pictures!

For a 1060...at least all the 1060s I've seen....there is one 6 pin jack for a 6 pin PCIe plug. This is usually labeled PCIe or sometimes VGA where the cable connects to the PSU.

Being the 1060 draws less power than the 660....I don't think your PSU is the issue.

Same could be said to you. Pictures would certainly help us understand what might be wrong.

The exact models of power supply and GPUs would be very helpful.

If your new GPU has any empty power connectors, that is the problem. All the pins need to be populated. If you have plugged a single 6-pin connector into an 8-pin, that will not be enough. Dual 6-pin to 8-pin adapters exist, and often come with cards. If your new GPU only requires a single 6-pin power connector, then I'm not sure what to tell you, plugging it in should be all that is needed.

Now these new GPUs can be a little incompatible with older hardware. It might require a BIOS update to your motherboard if it is not UEFI compliant.

Psu: chieftec 650w
Gpu: nvidia gtx1060
Intel i7 3400/8m

Well that seems fine. If you haven't tried the other PCIe cable, do so. Re-insert the graphics card if you haven't. Video card sag from the previous card might have gotten the pins out of shape, or dust got in there when you swapped them.

There are two versions of your motherboard. Make sure to confirm which one you have (1.0 or 1.1) and try the latest BIOS revision. This might get it to boot with the new card.

Other option is to re-install your old card, confirm the computer is still operational, then remove the old graphics drivers. Before allowing them to be re-installed, shut down the computer. That way you have a clean slate for the new card.
