First Panic Attack ...helPPP

Hiho , just got into stripping down my p4 pc to rebuild it with a amd 64 giga-byte k8n-sli board and I notinced that the power connector on the p4 is 20 pin and the amd is 24 pin . Do I have to buy a power supply now aswell ?

If the answer is 'no' post here , if the answer is 'yes' post a tenner !

Heinrich

Get to Peats or Maplin for an adaptor. Depending on the output of your PSU it should do the trick.

I notice on the enlarged pic of the motherboard on the Giga-gyte site that the board has the last 4 sockets blocked off , would I be right in presuming that I put in the 20 pin from 1 to 20 and the other 4 pins are from the 4 pin connector and go in the 4 pin connector socket ?

yeah , I know guys , i 'm using guess work here . But if ye are not used to me by now , ye never will be .

Newer Pentium 4 motherboards, like the one we used for the Socket 775 Pentium 4 in the 4th edition of Build Your Own PC, may have a 24 pin eATX connector instead of the standard 20 pin connector. However, they are usually designed so you can still use a standard ATX power supply with a 20 pin connector and just leave 4 of the pins unmated, and the socket should still be keyed so the connector can only go in on the right side. However, the presence of a 24 pin connector is telling you that the motherboard has a high power requirement, and you'll probably have the option to attach another 4x1 drive connector to supplement power.

yeah ?

It is correct.
My board (Abit AN8) has a 24 pin power connector, and I just have 20 pins connected as my PSU is old. I have the separate 4-pin ATX12V connector plugged in as normal.

Khannie

Yes, but DO NOT plug the extra 12V 4 pin connector into the empty four pins on the ATX connector....they go elsewhere on your mobo. Just leave them empty after plugging in your 20 pin connector or do as the article says and get a converter for a molex.

Stephen

The atx12v connector should be keyed in such a way that it won't fit without brute-forcing it anyway

My Asus A8N-Sli board will not work on the 20 to 24 pin arrangement. If you take the risk of frying something on the board go ahead and tell us the tale of woe later. This adapter is not expensive.

the adaptor does nothing as all it does is split the line already coming from the PSU. It may help due to the circuits now being grounded, but I doubt that would make a difference. If your computer does not work with a 20 pin cable attached, then just look at buying a proper 24pin psu.

Also, make sure you don't plug the extra line into the spare 4 pins, they go in their own seperate connector. Even newer boards now have a 24 pin AND an 8 pin socket, replacing the 20 pin and 4 pin sockets respectively.

The Enermax liberty, for example, has every conceivable connector that is needed (right now).

That's probably because you have a crappy PSU tbh. There's no electrical reason it shouldn't work, and it certainly wont fry anything to try without the adapter (especially in gigabyte mobo's, which have the extra four pins blocked by default).

Using a converted molex off a 2nd rail may also help, but it's a sign that your PSU might be struggling.

Right , given that I am replying from it , I think we can take it that it works . Found an article on it on the enterwebby thing and as said above you just blank it off .

Talked to one of my techie mates later on it the day and he was saying that power heavy users would use both the 24 pin socket and the 4 pin but adverage users could use the 20 in the 24 socket and the 4 in the 4 .
