[SOLVED] Accidentally plugged pcie 6+2 cable into 4+4 Pin on PSU Side (Fully-Modular PSU)

Hi All. Accidentally plugged pcie 6+2 cable into 4+4 Pin on PSU Side (Fully-Modular PSU). Both are similarly keyed so the pcie cable went in without problems. I have corrected it now and the pcie cable is connected where it should be. Should I be worried?

Just for reference this is my PSU connector diagram: PSU Connector diagram. Its a 2019 Corsair RM750.

Thanks gus

I did the same mistake and I'm happy nothing went wrong. I could have damaged my PC or GPU.

Do you have the same PSU? Luckily for my PSU the 4+4 Pin connector on the PSU supports both 6+2 Pin Pcie & 4+4 Pin CPU Power connector lol. My PSU's Connector diagram

The plug on the psu is irrelevant. It could be a 4pin, 6pin or 12pin, doesn't make a difference. What matters is 2 things. The plug(s) on the component end and the actual plug used on the psu. Most modular psus use the same outlet for pcie, cpu eps, Sata/molex, peripherals.

At the psu it's only a connection, the amount of pins is irrelevant, it's the polarity thats important.

For instance, an 8pin at the psu might be ground on top, power on bottom. The 4+4pin and 6+2pin would both plug into the same outlet. However, at the component end, the 4+4pin has power on bottom/ground above whereas the 6+2pin is reversed with power on top/ground below. Opposing polarity at the component end, even if supply connection is identical.
