Fasgear PCI-e 5.0 Extension Cable,16Pin(12+4) Male to PCI-E 5.0 4x8(6+2)Pin Female Sleeved Extension Cable, 40cm 12VHPWR Cable Compatible for GPU GeForce RTX 3090Ti & RTX 4080 4090 (16AWG/Black)

• 【Notice before shopping】To order a correct extension cable for your PSU and GPU, we recommend you had better confirm the RTX 4090/4080/3090 Ti GPU's requirement of the output wattage of PSU. We do recommend you use more than 1000W power supply to get a better and stable performance. If this cable is not suitable for your power supply or you are not sure about your port type, please feel at ease to connect with us. Don't plug and unplug by force.
• 【Designed for RTX 3090Ti / 4080 / 4090】Fasgear PCIe 5.0 16(12+4)pin male to 4X8(6+2)pin female sleeved extension cable is designed for GeForce RTX 3090Ti, RTX 4080 and RTX 4090 GPU. That means, this PSU cable can extend the length and work well with the original power cable to get a stable and reliable performance. Note: This GPU sleeved extender cable is not suitable for 12pin GeForce RTX 3090 Series GPU. Only support 12+4pin female GPU like RTX 3090Ti, RTX 4080, RTX 4090 and 4000 series.
• 【Up to 600W Output】Fasgear PSU extension cable supports up to 600W output. The plug terminals of the graphics card cable are made of alloy copper and tinned material, which can bring stable and higher currents. NOTE: This extension cable requires four unoccupied 8-pin PCI-e ports on your power supply to properly function. Connecting fewer than four connectors to your power supply may cause system damage.
• 【Neat and Tidy】Fasgear 40cm 4*8(6+2)pin GPU riser extension cable, compared with the original 10cm power cable, can make your DIY computer system neat and tidy. With 4 transparent cable comb acrylic clips, it is convenient for you to manage this sleeved extension cable cord. Thus, this extension cable can make the appearance of the computer system more beautiful.
• 【16AWG Tinned Copper Wire】Fasgear PCI-e 5.0 extension cable contains 16AWG tinned copper wire. Compared with the standard 18AWG power cord, this updated 16AWG tinned copper wire can bring stable voltage transmission and higher power output. Meanwhile, this tinned copper can prevent oxidation.

• Our cable uses High Conductivity Copper Terminals, which can carry current up to 10-12A. 16AWG copper wire can also carry 12A current. Theoretically, there are 3 power supply circuits within an 8pin. 10A*12V*3=360W, that means, a single 8pin can carry a maximum of 360W power. The amount of power output depends on the capacity of the power supply. In theory, a single 8pin port of the power supply can output about 300W.

👂Will it affect using when the cable has 2 empty pins?
