8-pin +12v Power?

post #1 of 4
Thread Starter 
I just got a new Intel Mobo and it has a 8-pin CPU power Plug instead of the 4-pin one. It also has the newer 24-pin mobo power plug. I got a PSU that has a 24-pin mobo power plug but it has the 4-pin CPU power Plug. I got this stuff off newegg so I dont want to half to deal with sending the PSU back. Can you buy/make an adapter? (I am going to have a bunch of spare molex connectors)

Check your manual for the motherboad. My ASUS has the same set up, and here's what the manual said. You can use a 8 pin if your PSU has one, otherwise, just plug in your 4 pin to one side of the connector. (If you look at the schematic in the manual for the plug, the bottom 4 pins are all grounds and the top 4 are all 12v, they are the same)

Now, mine came with a plastic cover over one half of the plug, so it was easy to figure out which side to put it in. If yours doesn't have that cover, hopefully your manual will tell you which one to use......or it's possible it doesn't matter.

ya I noticed you could plug a 4-pin into 1/2 of the 8-pin connector but that cant be stable at all .... i mean that would be cutting the power in 1/2 how would that work? I just cut a 4-pin off an old PSU and found a position, even thought the shapes dont match up, which I could force the plug into the other 1/2 and i wired up the top 2 pins to a +12v on a molex and the bottom 2 pins to the -12v on a molex so now I have a homemade 4-pin to molex plug which im hoping will work. My RAM is coming today so I will be able to test it later tonight.

Yeah, I wouldn't really recomend forcing plugs.........


It's not really cutting the power in half, just changing the way power is distributed. And mostly it's to simply allow those people with the PSUs with the 8 pin to use the board......unfortunatly, the ASUS website appears to be going wonky, so I can't provide a link to the manual for my board to show you exactly what it says.

Like I said, check your manual, that is the final word. If it says different, than go with it.......but I can assure you that my system is quite stable with all power reading solidly in the green.......
