The new ASUS mobo im buying has a 24 pin slot but my antec PSU is only 20 pin. Now I did read the FAQ at the top but his example was on an Intel and my new computer will be AMD. Do you think a 20 pin 430W Antec PSU will support power for this computer:

ASUS A8N-SLI Socket 939 NVIDIA nForce4 SLI ATX AMD Motherboard - Retail
AMD 64 3700+ San Diego
Evga 7800gt
WD Raptor 74gb
1.5GB Corsair XMS
SB Audigy 2 ZS
Plextor DVD-RW

Best way is to try, i know the msi diamond takes a 20 pin psu no problems.

You can always buy a 20-24 adaptor not many recomend doing that thou ive had no problems with mine.

Step 1. Save up $40.

Step 3. Enjoy.

I was reading the manual for my psu and it says " single 20 pin Main Power Connector, a 6 pin AUX power connector, and a 4 pin +12v power connector". Now is that 4 pin connector the one I need to make a 24 pin connection? Also, what is the 6 pin AUX connector for?

the 4 pin IS NOT the connector that you need for the 24 pins, it is a separate connection on the motherboard. the 6 pin is for pci-e cards.

No that is NOT what that 4 pin is reffering to. That would be for like CD ROM drives and such. Save up some money and just buy a new power supply. Get another ANTEC though!

The 2x2 4 pin connector is the 12v power source for the mobo.

I'M with dean all the way

I'll put the third vote in, buy the 20 to 24 pin adapter for 5 bucks on newegg and your problem will be solved. Also just use the lower end where the 20 pin fits I did that with my msi board before I became aware of an adapter and it worked fine. I just bought another psu, it was time though and I had the money. The boards are reverse compatible with the 20 pin.

Thanks for the replies! Well I decided im just gonna buy a new PSU. I will need one for going SLI anyways so Im gonna get this one:

Good choice.

I'd personally get this one instead:

dual-12v lines and dual-pci-e

hmm im really confused by this dual rail stuff... the one I chose has a +12V of 36A but the one you chose is +12V 13.4~15.6V... how can that be strong enough for a 7800gt?? And what happens when I go SLI?

I think you looked at the wrong thing. Each 12v line has 22A's. It's supposed to be more stable because one goes to your videocards and the other goes to your cpu and other components, afaik.

As for SLI, afaik, each card will need it's own power connection. The Liberty series has two connectors, I couldn't tell if the one you posted does or not.

The enermax liberty series have dual 12v rails and dual pci-e connectors. Because of the modular cableing design on the libertys, the pci-e connectors have specific plugs on the psu. I had the liberty 500 and was very, repeat very, impressed. I went up to the liberty 620 because I got a great deal on it. I bought the 500, and a week later Microcenter put their psu's to 20% off, which made the 620 only $20 more, so I stepped up.
Btw, either liberty will handle sli very well.

oops your right I was looking at over voltage protection... ok well then if 22A is enough then I will go with that one if it worked really well for you. thanks!
