24 pin ATX

Post by **YourGrandpa** » Mon Feb 14, 2005 4:02 am

My bud just ordered a new mobo, RAM, video card, CPU, and case/power supply combo. He called me in kind of a panic because his PSU's ATX plug didn't match the mobo and thought he was going to have to by another PSU to make things work. I told him I wasn't aware that the plugs were different and would look into it. Well, after a breif search I found out that you can by a 20 pin to 24 pin adapter that inables you to use a 20 pin PSU on a 24 pin mobo. Needless to say, he was pleased that it was only going to cost him another $6 to make eveything work. But what I didn't find out was, what's the four extra pins for? I'm guessing it's for PCIE.

Thats generally for higher-powered P4's and maybe some AMD64's. If his PSU doesn't have the extra pins, then I'd be wary of just using an adapter, most PSU's will have the standard 20-pin and then a 4-pin square one that just connects after the 20-pin.

it is to put the P4 4-pin power adapter beside the 20-pin ATX, if there is another 4-pin connector on the mobo then you have the choice between the two. At least that what is was on a mobo I built with

Just to clear some things up.

The CPU is an AMD 64 3500 and he did try to plug in the 4 pin plug next to the 20 pin, but it didn't fit.

It's a Chaintech PCIE board. But I don't think the brand of board matters, because I've seen the 24 pin setup on several different board types I've looked up.
