Why is it so difficult to find the right atx eps female connector?

[TheNoviceModder]

My new sf750 was delivered today & I want to start prepping to create a new set of custom cables for it but I'm struggling to find an eps connector with the below layout. This is a photo I took of the eps cable that came with the psu. I have no trouble sourcing the other end but no other connectors match the below layout of square vs non-square bits. Do they exist or will I just have to remove this connector from the stock cable?

I can't find 8 pin connectors with the same layout but I can find 4+4 pin connectors which is what you have with the same layout on Ebay.

Yeah I can find 4+4 eps connectors but not with this layout. Not 100% sure why other than the possibility being that these are type 4 cables but from what I understand the only difference between type 3 and type 4 connectors is the 24 pin pinout where I counted 28 pins on the psu side on the type 4. I think the normal 8 pin eps connectors will do me just fine

That's from here.

I can only find the white/clear connectors, I'm after black ones but I can't find them anywhere
