What is this 8 pin connector on the Earthwatts?

Hello

So I am doing my first ever build, and I dont know the purpose of this 8 pin connector on the Earthwatts.

The connector can be seen in this link, they called it an 8-pin EPS +12v Cable

It plugs into the motherboard to power the CPU. Cheaper boards for chips requiring less power may only have a slot for a 4 pin connector. The EPS server standard calls for an 8 pin connector and most decent ATX motherboards for high powered chips have a 8 pin connector.

I've heard it also helps with boards running double graphics cards. If your motherboard doesn't have a slot for it, it can be safely ignored. Just read your motherboard manual to be sure.

+1 for HOOfan.

-1 for DSF. The 8-pin EPS12V receptacle on the board has no traces to the PCIe slot. The power goes straight to the CPU VR's on the board.

Ok, thanks for the info. I had seen that bandied about more than once on AT and other forums, and it never really made much sense to me. I should stick to posting things I'm sure of.

This is a followup question.

I just replaced my power supply because I was getting random bsods and problems on wakeup. I had a Seasonic 500w and replaced it with a Corsair 750TX.

Anyway, I have anAsus P5KE/wifi motherboard, 4gig and a Q6600. The 8 pin connector came with 4 pins covered. When I built the system, I used a 4 pin connector and did not use the 8 pin plug (I am not sure why except maybe ignorance). When I installed the 750TX, I used the 8 pin plug. I am not sure why but the machine seems a little more peppy now. Is there a reason for this or am I just imagining?
