need help with psu hookup

post #1 of 4
Thread Starter 
I am building my first rig. Complete rookie!

I have a Seasonic Platinum 1000 that I am connecting to a Sabertooth X-79. The mobo has an 8 pin connecter.
The psu has an 8-pin labeled cpu and a 12 pin labeled pci-e/cpu.

Modular cables include:
1 with an 8 pin at one end and a 4+4 at the other.
1 with a 12 pin (4 are empty) and an 8 pin at the other.

Do I use the 8/4+4 or the 12/8 in the pci-e/cpu connection.
does it matter, whats the differance?

The 12-pin is able to power a PCI-E card such as a video card or a CPU. So, it's kind of "universal' in that respect. The 8-pin is only for the CPU. The reason the 12-pin is labeled "PCI-E/CPU" is there are some motherboards that have two CPUs on them. So you'd just use the 12-pin connector to power the 2nd CPU. So, I recommend using the 8-pin so that you still have the 12-pin for a PCI-E card such as a video card. You never know if you'll need it. ;)

Thankx. I was hoping not to burn up $700 worth of parts from the jump.

Yeah, don't wanna break the new toys! :) hehe

 

So just so I know that I was clear, plug the 8-pin > 4+4-pin for the CPU and leave the 12-pin laying around just in case you need it (like in a drawer or something).
