GPU has 6 pin conectors, but PSU only has 6+2 cables

[Kalrito]

Can I still use this for my gpu without worry of something going wrong?

You can still plug in the GPU to the PSU, just don't connect the extra 2 connectors.

You don't have to worry about anything, those to plugs are like that so you can either use it for 8-pin power connector or 6-pin power connector.
