ATX 1.0 Running ATX 2.0?

[knownalien]

<A HREF="http://www.antec.com/us/productDetails.php?ProdID=20550" target="_new">this</A> is the PSU I currently have.

Is the ANY kind of adapter that can allow me to use this PSU with the newer PCI-E boards which all use 24 pins now?

The second link is the wrong idea for you, but yes, you can buy an adapter. Of course, you might not need to, several of the boards I've tested work perfectly using the 20-pin lead in a 24-pin socket.

well, my psu has a 20 pin connector and one 4 pin 12v connector. I am reading that you can run this <A HREF="http://www.asus.com.tw/products4.aspx?l1=3&l2=14&l3=0&model=454&modelmenu=1" target="_new">mobo</A> with a regular 20 pin ATX 1.0 connector, but you still have to connect the 4 pin 12v connector somewhere.

All of the 24-pin boards I've tested use BOTH 24-pin AND 4-pin in different connectors. The 4-pin has 12v+ground only, the 24 has one 3.3v, 5v, 12v, and ground added to it.

So your only choices are to try the 20-pin with 4-holes empty (since the 4-pin is a different voltage and plugs into a different place), and add a 20-24pin adapter if 20-pins won't do.

so since my 20 pin also has 12v coming out of it, the mobo will just draw more from those pins? I am reading who people just plug their 20 pin into the 24 hole. The seperate 4 pin plug of my PSU (and others of the ATX 1.0 standard) is for use by the CPU. I guess my question is, where is the mobo getting this "extra" 12v it thinks it needs? from the 12v pins of the 20 pin connector of my psu?

OMG! I already told you, most boards use BOTH the 24-pin and 4-pin, they go in separate plugs.

And if you use a 20-pin, the 4-pin goes where it would have before. 20+4 does NOT equal 24 in this situation, because there was, is, and will be a 4-pin SEPARATE plug on most boards.

Your board will get it's 12v power from the six or so 12v leads on the 20-pin connector. The CPU will get its power from the separate 12v connector. 24-pins has nothing to do with that.

I believe the main reason you see companies using 24-pins is because PCI-Express slots are made to support more output power. But for most video cards this won't be an issue, many of them have a 6-pin plug of their own! The CPU still gets its power from the 4-pin plug at a different connection.

BTW, I have about six or seven of those 24-pin boards here right now, they all have 4-pin connections as well.

I've found the 20-24 pin adapter at newegg, but as you say, you don't need them. I know the 20 pin psu connector has that tab on it so that it forces you to plug it in in only one way, so since you are leaving the last 4 pins on one side unopened, you don't have to alter the psu plug to seat properly in the 24 pin slot do you? it's hard to tell on the internet where the "groove" is in the 24 pin slot of the mobos. It must be the same groove placement, just allowing for one side to be longer to accomodate the 4 additional pins.

did that post make sense? lol

Each of the square plastic pegs the goes around the pins is oriented or sheaped so the connector can only be plugged in the right way. The adapter might be worth getting, but only if your motherboard complains, or your system isn't stable. The only way the adapter would be needed for stability is if the main 20-pin traces on the motherboard aren't thick enough.
