Cable Confusion Ax 1200i

[jony47]

Hi, guys

 

I have a cable confusion and its a 2 part question

 

1. i have a gigabyte h77m-d3h mobo and it needs at 12v and it is a 4 port

But the cpu connectors from 1200i is 8 pin and when i looked closer i found out that it can be split to 2 4pins.

 

My question is can i use any one of these and leave the other one hanging without any problem ?? (look below for pics of mobo pin and pin from 1200i)

Now for my second part of my question

 

I have a nzxt phantom 410 case and it comes with 3 fans with already connected to the speed controller and i need to power these fans with a 3pin molex (actual 4 but one pin is missing). I know it works because its working fine with my 600W psu.

 

So my question is, in my 600 W PSU there are 4 pins coming out of psu to the 4 pin molex, but in ax 1200i the molex cable which connectes to the psu is 6 pin. So is there a power difference and will this work if i connect them both ?? (see reference pics below)

Answer to the first question: Half of that connector will plug in without force. Leave the other half "hanging", unused.

 

The second question I do not understand. It's a 6-pin connector to the PSU, but only four pins are populated. On your case, they're only using one of the two grounds. So what's the problem?
