Stop Connecting Your GPU Power Cables Like This! (How To PROPERLY Connect PCIe Cables For GPUs)

It's really easy to accidentally UNDERPOWER your graphics card by using a split pigtail cable (also called y-splitter) for 2 or 3 of the PCIe connections on the GPU. Unfortunately a PCIe cable can supply as little as 150 watts from your PSU to the GPU, resulting in too low power being supplied to some graphics cards - especially ones with a TDP above 225W.

This isn't an exact science, though, because the motherboard PCIe slot supplies 75 watts or so, and some PCIe cables/PSUs can supply MORE than 150 watts.

In general though, I dive into exactly what you need to know here so that you can PROPERLY connect up - and power - your graphics card.
