That 8 pin mobo power connector issue again...

post #1 of 8
Thread Starter 
Ok, I looked for answer here and found some threads re this issue but need clarification.

My MSI P7N Diamond has the 8 pin socket and my Antec 1KW PSU has got the matching connector BUT the socket on the mobo is partially blocked off with removable tab.

Atm PC runs fine with just a 4 pin 12V connected.

I got Q6700 in the mobo + 2 x 9800GTX and 4GB RAM

So should I remove the tab and connect the 8pin plug?

TIA

If you have the 8pin, then sure, why not, more juice to the system, If not its not a big deal

Well yeah thanks, that seem to be common sense thing to do.

I just find it poor that this is not documented in the mobo's manual. There is no explanation anywhere what is the purpose of this connector - well obviously to provide more juice but it would be nice to know where this power goes to.

The manual shows the connector but only mentions that it is for 12v 4 pin connector.

well... id say if it aint broke, dont fix it. but of course, if you want to tinker with your equipment, just be prepared to replace it if it breaks.

The 8pin connector just allows for a higher current draw (when needed) than a 4pin connector and so decreases the likelihood of overloading the wires.

When the transition from 4-pin to 8-pin occurred, they made mobo's so that you could get away with not upgrading your PSU and still just use the 4-pin, however, it is usually the case that when you OC, the 4-pin is no longer going to cut it.
