Question about 6+2 and 8 pin PCIe differences

[Pandabytes]

I’m looking to buy some custom cable mod extensions. I want the pro cables and was wondering if the 8 pin PCIe works the same way as the 6+2 pin PCIe.

They're effectively the same thing.

Some graphics cards have 6pin. The 6+2pin is so it's compatible with both 6pin and 8pin cards.

 

Just don't confuse them for the 8pin (4+4 pin) EPS12V (CPU power) connectors.

8 pin PCIE = 6+2 pin PCIE.

as a matter of fact, 8 pin PCIE doesn't exist. It's all 6+2 pin.

 

Of course on a videocard it looks like an 8 pin connector, but the cable will always be 6+2 pin (or 6 pin):

It's just that some companies will call it '8 pin'. But that can be confused an the 4+4 pin (8 pin) EPS connector, that goes to your motherboard.

 

So if you're buying an extension cable, do check if it mention PCIE, videocard or 6+2 pin.

If you're buying the 4+4/8 pin EPS connector, check if it mentions CPU, motherboard, 4+4 or EPS.

Cable Mod has 6 pin, 6+2 pin, and 8 pin PCIe cables, but only the 6 and 8 pin cables are pro compatible, so that is why I was asking about the differences.

Power supplies with an 8pin non-detachable PCIe connector do exist. Not sure why you'd say they don't. They are rare, but they're there.

Wasn't aware of this, thanks for the link

I guess I should have said '8 pin PCIE usually doesn't exist and often is 6+2 pin PCIE'
