6+2pin extension or 8pin extension (PCI-e) confusion

Billys11 · Sep 13, 2017

I have an EVGA 750G2 power supply and I am looking to buy some bitfenix cable extensions for my graphics card GTX 1080 SC2.
I am not really sure as to which extension I should buy. Bitfenix offers a 6+2pin and a straight up 8pin extension. My GPU requires only an 8pin.
Can someone clarify if there is any major differences between these 2 extension cabes?
My main concern is with the compatability with my PSU

For you, since your GPU needs 8-pin, there is no difference. 6+2-pin is for someone who owns card that requires 6-pin, but will upgrade in future to card that requires 8-pin, and does not want to buy another cable after GPU swap. Electrically, such cables are identical.

"Cable Extensions" (such as the Bitfenix Alchemy 2.0 Extension Cable Kit: https://www.bitfenix.com/global/en/products/power-supplies/alchemy-2-0-extension-cable) are compatible with most/any PSUs (as it only "extends" the stock cables of such PSU without any risk of incorrect pin-out/pin-definition). "Cable Replacements" (such as the Bitfenix Alchemy 2.0 Modular Cable: https://www.bitfenix.com/global/en/products/premium-modding/alchemy-2-0-modular-cable) are not and should be selected carefully to match the correct brand and model of the PSU.

To use a 6+2pin or a straight up 8pin PCIE (or even a straight up 6pin PCIE) is a matter of preference and is dependent on the GPU socket required. Since you have the EVGA GTX 1080 SC2, you can use either the 6+2 or the 8pin. Just make sure you are getting the "PCIE" extension (as there is also an available 8pin extension cable but for the "ATX12V/EPS").
