Is this bad? (PSU question)

There's a missing metal piece, please tell me this doesn't mean I have to return it..

Maybe this will help.

I just had a quick look at mine.  It is also missing that pin.

Nothing to worry about.

Plug 'n' Play man.

Thanks tons for actually checking dude! I was assuming it was fine, but ya' know something like that you can never be too careful. Didn't wanna fry my new gpu!

You mean fry your motherboard? 

Anyways not a problem dude.  And you're right you can never be too careful.

If in doubt, check it out I say.

That missing pin is for the -5v used by older computers, but now modern motherboards have no use for the pin hence the omission.
