Cooler Master CMA-SEPC18XXBK1-GL 12-pin To 2x8-pin VGA Adapter

Power Your RTX 3000
The future of GPU power cables is 12-pin PCI-e connectors. As graphics cards become more intensive and adopt higher power consumption needs, larger connectors will be implemented to meet these power demands. But your new 750W+ Cooler Master power supply unit comes with a long warranty and will last for several more years. Rather than buy a new PSU when you already have a working unit, use the 12-Pin to 2x8-Pin VGA Adapter. Turn any ATX power supply unit from any brand into an RTX 3000 series capable PSU.

Universal ATX Compatibility
Your RTX 3000 series GPU is universal. It will work with any standard ATX system as long as there's enough room in the case and the wattage to support it. Cooler Master believes your PSU should work the same way. One new part shouldn't force you to have to change your power supply unit, and with the 12-Pin to 2x8-Pin VGA Adapter you won't have to. You can use this adapter to power your RTX 3000 GPU, or any future 12-pin connector GPU, regardless of what brand your PSU comes from.

Not Too Long or Too Short
The 12-Pin to 2x8-Pin VGA Adapter is 400mm in length. This cable length was chosen intentionally after a considerable amount of testing and research. With 400mm of cable this adapter should be able to reach any connection point in any system without adding an unmanageable amount of excess cable to deal with. The flat black cable design delivers a subtle appearance that won't completely throw off your system's appearance.
