I am looking at purchasing the Antec 1080AMD Case which come with the Antec True Power 430W powersupply unit. I am also interested in purchasing the Asus A8N SLI Deluxe motherboard.

The motherboard manual states that the power requirements are: "ATX Power Supply with 24pin and 4 pin 12V plugs. ATX 12 V.20 compliant"

Does this mentioned power supply meets these requirements?

Cheers,

Kerry

The new version of the TP430 gives you plenty of amperage on the 12v rail. But the psu is standard 20-pin ATX instead of the 24-pin. I wouldn't have an issue using this psu with an adapter (Thermaltake) as Antec provides multiple wires to the 12v pin socket on the connector.

I am really concermed with attempting to use a 20pin cable on a board designed for a 24pin cable. Are there problems associated with this?

How long will it take for the 24pin standard to be applied to most power supplies. It seems that virtually all of Antec's are 20pin. I really like the Antec 1080AMG Case, (because it comes with a good power supply) But I don't want to pay $170 CAD for a case power supply where I am just going to have to change the power supply later for an additional $150 CAD.

If there is an adapter where can I find it?

One of the guys in another thread (Guitardaddy maybe?), said that using an adapter will cause extra resistance therefore dropping your voltage coming into the motherboard. People with Antec 550W PS (20 pin versions) are not having issues when used with this motherboard.

I just installed a TruePower 430 last night replacing my SmartPower 350. Got it at Microcenter for 84 bucks not bad. Had to make sure it was the new version with 26a on the +12v. I had no problems with it for the 3 hours I got it installed and ran HL2 and did some surfing etc. I replaced the smartPower 350 just because I wanted some more juice but even with the Smart Power, there were no issues with the 20 pin on the 24 pin board. I shouldn't say no issues because once I did get a hang on bootup but it was solved when I reset. Otherwise in my experience, the 20 pin has worked fine.

Ok I read the other threads...I am certainly as confused as the guy who went to get a beer.

Please correct me if I am wrong.......

The Antec 430W True Power that comes with my new Antec Case will be fine even though it only has a 20pin connecter. I can leave the other 4pins (closest to the VGA card open) no adapter required because the extra four pins are used to supply extra power to the PCI-E slot.

My rig is pretty basic, only using one 6600GT card for now. If I want to upgarde to dual 6800 cards I will most certainly need to get a 24pin power supply.

Is this right? I have no idea about all of the "dual rail, single rail" stuff. But I think this power supply has something like 25A on +12V.

Cheers,

Kerry

the truepower 430 that you have currently for your rig is more than adequate for your needs. It is single rail for what its worth, has 26A on the 12v rail, and is an Antec so it's high quality. Just as you said, connect the 20 pin leaving the 4 pins closest to the vga open, connect the additional 4 pin (square) to the connector near the processor and the regular 4 pin molex connector to the slot near the vga and you will be set.

What 2x said. The reason why you can't run all psu's with the 24-pin adapter is that many of the cheap units only use one wire to the 12v pin on the atx power connector from the psu. The Thermal take 20-pin to 24-pin adapter creats a branch circuit from the three power rails at the 20-pin atx connector. Good psu's double the power leds (wires) from the psu to the atx connector. Antec's psu have the double leds to the connector, so making a branch circuir through the Thermaltake adapter doesn't pose any risk of having the psu's leds melt do to over drawing on the rail.

I appreciate the quick responses. To clarify I have not actually purchased my case/PSU yet, so I don't know what all of the connectors look like.

1. No adapter required.
2. With my stock Antec 430W PSU there will be on cable with 20-pins, and two cables with 4-pins? These cables should be attached as per 2x direction?

I apologize if these questions seem very trivial, I am a noob.

Cheers,

Kerry

After writing this......I found some information on the Antec website. I am sure this could help many people who have the same questions I do.

The link discusses using the 20pin powser supplies with the newer 24pin motherboards.

Excellant link. It's a brand new link too. But you see that each and every reference is regarding Intel motherboards. I've been argueing this point for days concerning the origin and use of dual rail psu's. The new Antec True 430 you have coming will work just fine for you. You've got the EZ-Connector to add additional current to the second PCI-E port, and if you decide to use 6800 Ultra's, the cards will require their own power (from adapters).

I noticed the Intel only reference. However, I figured the 20pin cable use on a 24pin board was probably transferable.

I din't plan on adding or upgrading my choice of video card anytime soon so it shouldn't be a worry for a while. I noticed Antec discussed the dual rails (again I am lost with this stuff) but it seemed to me that Antec was promoting Dual Rail PSU as a good thing.

Yes. Dual rail psu are good for certain types of systems, just not AMD SLI systems is all. They were engineered for Intel systems. And work fairly well in some multi-processor boards, where each cpu/memory bank get their own rails.

I have dual 6800GTs with the Antec 550 20pin and it's working fine (I didn't do enough homework, otherwise I'd have bought the 24 pin version as it was only $5 more, grrr)

Not trying to muddy the water here but I emailed Antec about using the 430 true power on an nforce4 motherboard with 24 pins. BTW, I'm not even wanting to do SLI, I am going to buy the Ultra version. Here is what she said: We do not recommend using the 430 tp on a PCI express motherboard. You would need to buy the the NeoPower 480 with the 24 pin connector. We don't sell 20 to 24 pin adaptors and do not recommend their use.

It's possible she was trying to sell me something but I don't think so.

Thats hilarious:laugh:

She was pushing you away from a ps that works perfectly on this board
to a dual rail model thats totally unsuited for this board! and costs more

Informed Customer service at its best!:beer:
