Use of this cable with any non-certified or unsupported EVGA power supplies or power supplies from another manufacture voids the warranty for this cable, and may void the warranty of your power supply. You can find power connectors that are not compatible with the motherboard or other hardware in the computer. First of all, turn your PSU off while plugging in, then remove the PSU panel and unscrew the older GPU, and take out the cable integrated into the PCIe slot.

Motherboards come with the aforementioned PCI Express x16 slot that can provide a maximum of 75 watts of power. However, in many cases, when the GPUs get developed too advanced than the PSUs, the manufacturers offer you power connectors and adapters to make the GPU compatible. Here are some adapters or converters that you can use to compatibility with your desired pin connectors.As noted in the earlier sections of this editorial, the 12-pin GPU power connectors are the most recently deployed technology in the case of GPUs. However, if you still want to go with your decision of adapter connectivity, then you must consider connecting Molex to Molex connectors. In conclusion, these are the differences that you should know about 6-pin, 8-pin, and 12-pin connectors.

This tool allows you to create a custom 8 pin PCIe GPU extension cable – ensuring your cables perfectly fit every aspect of your colour scheme. 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. You can't connect male PCI-E 8-pin to EPS-12V because 2 male pins on PCI-E as the top edge joined together and the corresponding pins on PCI-E does not have a slit for that. For example, they may pull 80-90w from the 8 pin connector, and 30-50w from the slot, for a total of around 125w. 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.If possible, it’s best to use Molex to Molex for your GPU needs, as they have thicker wires and can transfer more current. Despite the fact that 150 watts are enough for most graphics cards, high-end cards such as NVIDIA’s RTX 3080 require more than 320 watts and system power of 750 watts.

If your standard PSU has a 4-pin Molex connector and is not compatible with the new-age graphics system, this adapter cable helps you with compatibility.
