4/8 pin ATX -- where does it go?

I'm so sorry for asking this, but my motherboard has 2 power inputs from the PSU -- the 24-pin ATX connector socket, and another 8-pin ATX connector socket. The PSU has a cable with a 24-pin ATX connector, and another cable THAT SPLITS INTO TWO 4+4 pin ATX connectors. My motherboard (ASUS p8p67) manual shows to connect either the 4-pin or 8-pin ATX connector from the PSU to the mobo's 8-pin ATX socket, but I am unsure whether I am supposed to connect both 4-pin ATX connectors (that split out from the single large cable in the PSU) or whether I need only connect one of those 4-pin connectors into the mobo's 8-pin socket.

I know this is a stupid question, but I'd rather ask that find out that I made a mistake later.

Thanks so much!
 
Yeah connect both "4-pin" connectors. They are split to allow compatibility for older boards which have only a 4-pin ATX connector vs. an 8-pin.

It should be pretty obvious which way they go.
 
Even if "you" think the question is stupid, the folks around here don't make you feel that way...

TRUST ME, I have asked TONS over the last few weeks...

Mnewsham has ya covered...
 
Well...I've always been of the "No question is stupid" belief...but lately, SOME posters have challenged that...😛

As mnewsham pointed out, the power supply 4/8 connector provides some versatility for different motherboards, and many NEW motherboards come with a small plastic cap over 4 of the pins in that connector to provide some versatility for older PSU's that only have a 4 pin ATX connector as well. Since your PSU has the 4/8 connector, and your motherboard has the 8 pin socket, DEFINITELY use all 8 pins.
 
Yes to the 4x4 like others said. The connectors are "keyed" by pin shape so be sure it fits correctly and don't try to force it.

Fixed, but correct besides the typo.

Full disclosure: Technically speaking, you could plug the 1/2 of the 4+4 that has the clip into one side of the 8-pin socket and it would work. That would kinda dumb since you have a full 4+4 connector that you can use.
 
Thanks so much you guys, you are all awesome. Thank you again soo much for your helpful explanation.
