Yeah, this image was posted by Seasonic, because their older units shipped with inadequate cables which couldn't handle daisy chained 8 pins. The usual 12-pin cables with 18 AWG-rated wires can extract up to 500 watts of power, directly bypassing the motherboard. These are usually the manufacturers’ highest-end models made to provide the best possible cooling and overclocking. After introducing 12-pin connectors, NVIDIA also worked for its PSUs with less than 12-pin connectors.

Power Supply Unit Extensions are the perfect way to create a rig that matches your vision, while offering quality power distribution around your whole build.The new-age graphics card consumes much power and demands a higher supply from direct external sources.

Less space between each individual cable add to the flow of your rig, keeping everything tidy and adding stability between connections.This move was made out of necessity as NVIDIA desperately needed the extra power for their most powerful cards and came up with a rather elegant solution. Our extensions can be used in conjunction with all PSUs, improving the aesthetic and airflow of any computer, from the tightest budget build, to an enthusiast’s next monster project. WARNING: Due to the electrical pinout of each cable and the unique electrical pinout designed for your power supply, using this cable with a non-certified or unsupported power supply may cause irreparable harm to your power supply, cable, and/or any connected devices. It might be only an exception found with FSP PSU, but a single difference in one male pin on PCIe connector allows to plug your PSU totally wrong. EVGA single power supply cables are designed to replace missing or lost cables for a limited number of EVGA modular or semi-modular power supply models, and are officially certified only to work on a limited number of EVGA power supplies, which can be found on the compatibility tab.

And third you can use daisy chained cables if they are proper 16AWG daisy chained cables, if you have something like an old Seasonic unit that shipped with 18AWG daisy chained 8 pins then don't use it. That is why you could get a 8 pins connector with missing pins, because it is in fact wired as a 6 pins with lower power. In several cases, you can also find manufacturers offering you premium 12-pin GPU cables with 16 AWG standards and the efficiency of drawing up to 600 watts of power. Tight crimps and a snug connection within the connector block ensure no loose cables or loss of power to your equipment.In standard PCs, the connectors connecting the GPU with the motherboard usually do not have the required number of pins to offer a higher power supply. So in theory, an pci-e 8 pin connector that has 3 pairs of wires carrying 12v to the video card could deliver safely around 9A through each pair. Below in this article, we have shared everything you need to know about those types of power connectors.
