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.

8-pin to 8+4-pin?

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.
