Can anyone help and answer the question should this look this way. Please see the keys. A friend is looking at it and never saw this before all the 8 pin connectors hes saw have the correct keys. This power supply doesnt seem to have that it's an rm750x and doesnt matchup with the motherboard 8pin 12v eps atx connector.

 

thanks

Looks like a 4+4 pin EPS plug to me.

Yeah it's not unusual to have all the pins on the right half with rounded keying. It doesn't have to match the plug as rounded pin goes into square pin fine.

On the corsair website it say this is the right cable for 8pin eps. It's nottill look at the keys you see they are slightly different tI the motherboard

Thanks for that my friend said that it's just unusual compared to his cables too. So that's fine and it would go into the 8pin on a motherboard thanks

Wait, is it 4+4 pin or 6+2 pin?

I edit my posts more often than not

I am the chap he brought it to. Hi Mike!!!

 

It's a 4+4 connector, however I have not seen a connector such as this with additional keys, The PSU end of the cable has the correct keys but the motherboard end has more chamfered than I would normally see. The cable is the correct way round as the cable retention clip can only be secured one way. I wasn't sure if this was a corsair quirk and was a little suspicious of the cable as this was accompanied with a component failure on initial start up. I have identified two possible causes. The motherboard component failure was under one the heat spreaders and could have been caused by a damaged MOSFET (either bad anyway or crushed through overtightening at the factory) or PSU issue but I didn't bother too much with that. 

 

Probably nothing and I doubt anyone would have ever noticed if not for the smoke. Do corsair normally make them like this or should I get my multi meter out before we drop another board in?

I think most brands make them like this today. It's that way on both my Seasonic PSU and my old Corsair.
