New cpu psu cable?

Recommended Posts

Posted · Original PosterOP

Hi

 

My psu is the CORSAIR RM650 80+ Gold Fully Modular ATX Power Supply.

 

The CPU cable is 8-pin to 8-pin. Now my motherboard has a 8 pina nd 4 pin connecter for the cpu. Now i would like to connect them both is it okay to order a new PSU cable for my CPU from for example cablemod that is 8-pin to 8+4-pin?

Or is that a bad idea for some reason i do not know?

 

Thanks in advance

There's no point in connecting the 2nd cable unless you're doing crazy liquid nitrogen overclocking...

It will work but not be of any use.

The motherboard effectively does this internally. The reason it doesn't come like this, is the connector is rated for a certain amount of current. By adding another 4 pin you're tricking the motherboard into thinking it can draw more current than it actually can.

Will it matter? Probably not. You'll only need the extra 4-pin for one-shot run OC's or LN2 OC's.
