I have an AA8 duramax socket T motherboard and a Aspire ATX 520W PSU. My PSU has a 20 pin connector cable but my motherboard has a 24 pin slot. Can i use my current power supply or will i have to purchase a 20 pin to 24 pin converter?

You will need an adapter. Thermaltake makes one.

The 20pin PSU is for use with normal AMD (Athlon XP, Duron, and athlon64) or Intel (p3 and P4) based Motherboards, but the 24 pin ones are specifically for the Intel Xeon chips (used in servers).

Therefore a 20pin PSU connector will NOT work in the 24 pin connection slot. However as stated above, you can get an adapter that should make it compatible.

Adam. The 24 pin power connector used to be exclusively the realm of server boards, but not anymore. There is a new generation of form factor BTX for desktop mobos. Part of the change to PCIexpress. The connectors on the new boards will be switching to 24 pin connectors in order to do away with the extra P4 4pin connector. The change over looks like it will phased in gradually and take over bit by bit, rather than a total shift to the new standards

You can use a 20-pin PSU with a 24-pin motherboard, just make sure you move it all the way to the right, the url below illustrates what I mean.

Yeah Adam, what Payton said...

Oh, and the new nForce4 boards will be 24-pin, I believe...

So Sander, do you need to connect the 4 pin connector as well into the left over spot?

No, does the image show that? The 4-pin goes to the other connector on the motherboard, located around the CPU.

I was assuming the extra 4 pins would replace the 4 pin connector. I'm just speculating. I saw the connector at the top right corner of the AA8 pic on ABITs site, but thought it was a 2 pin fan connector.

AH HA HA HA HA!!!!!!! JOHN. You are letting this thing stress you out WAY too much. Be a brave lad and pony up the $10 and buy an adapter so we can end this thread.

I read my MB manual again and discovered that it is compatible and my computer is now up and running.

It will work just fine, the problem is that not enough power will go to the pci-express card and if you have a powerful card that doesn't have a power connector (i.e. ATI x600xt) you will have many problems. I will never suggest to anyone to use a 20-pin connector instead a 24 one, and I think that labs that do that are making a great mistake. Apart from the fact I've written above (Intel cards put also a molex to give enough power to pci-e cards + the 24-pin psu) if you are a fan of overclocking you will understand what I mean in a moment.

Regards,
Amioran

Can PLEASE please some one help me.

Best regards to you all
