kenable 8 Pin PCI Express PCIe Power Cable from Dual 4 Pin Molex LP4 Adapter

Product Information

These are usually the manufacturers’ highest-end models made to provide the best possible cooling and overclocking. Most of the older PSUs have 4-pin SATA connectors, and thus, for one 8-pin PCIe, you would require 2- Pin SATA connectors. Although the math might not seem right when compared to the 6-pin connector, the 8-pin connector can deliver 150 watts to a graphics card. Fortunately, computers are made by engineers who like to modify hardware that isn’t suited to their needs by default. If the GPU requires more than 150 watts, it will come with an 8-pin connector or two 6-pin connectors.

So, assume around 200 watts can go into the motherboard through the 24 pin connector, which are then split between fan headers, rgb headers, and possibly 12v to 5v / 3.Inside every computer, there are a multitude of cables that connect power and data lines to individual hardware components. Ribbon cables and Molex connectors were traditionally used for this purpose but today we increasingly find cables are much smaller and flatter allowing for better cable management and to prevent a reduction in airflow. PCI-e organization imposed the limits of 75 watts for the 6 pin connector, and 150 watts for the 8 pin connector. 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. A top-of-the-line graphics card can place too great a burden on many PSUs, and that is something gamers need to avoid.

NVIDIA eventually developed an efficient cable system, as it needed cables to draw more power externally for its GPUs. Some cables come in all black, especially those come with power supply for cosmetic and some in all yellow anyway, you can't actually rely on the color.However, if you’re constructing a gaming setup with an RTX 3080/3090 or desire to prepare for the future (which is nearly impossible), you should select a stronger PSU. 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. The PCI-e limitation of 150 watts is chosen to allow 2 8 pin connectors on a single cable coming from power supply - keep in mind that there's ONE connector plugged into the power supply, usually with 3 or 4 pairs of 12v wires which are then shared between those 2 connectors. This product listing is for one individual custom 8 Pin PCIe GPU Extension Cable only and not a full extension kit.
