DFI 24-pin REQUIRED?

So tomorrow my DFI Nf4 sli-dr will be showing up. :) Anyway, I was looking over at DFI street and they seem to really make a big deal about how a 24-pin psu is ABSOLUTELY required for these boards. I know it's recommended and I'm sure it does make a difference with insane OC's and stuff...but how incredibly important is it, really? I currently have an original-version Antec Truepower 430 (20A on the +12V, for reference). Do you think I'll really see some issues with the SLi-DR, a winnie 3200+, an X850XT, and two hard drives, plus usual fans and stuff? I'm planning on getting a new psu sometime soon (probably a neopower 480) but I'm afriad I may have to bump that up if the Antec doesn't cut it.

I'm not too aware of how well this psu powers a 24-pin setup since my AX8 only has the regular 20-pin connector. (odd for a pci-e 939 board) It handles my current rig perfectly fine with dead-on rock-solid rails...all I'm going to change is the AX8 for a SLI-DR. Think I'll have any issues?

Any experiences?
 
Definitely shoot for a new PSU, your current TP430 only meets ATX12V v1.2 specification - lots of amperage on the +5V rail, and not so much on the +12V (20A isn't much these days). DFI requires a native 24-pin connection for the sake of stability and overclocking ability, but you already know that. ;)

The Neopower 480W is a pretty good choice.
 
Required = Required. Even with an adapter, it's still not going to work properly. It will probably work, just not properly. The official forum says not to, and you want me to tell you well maybe it's okay after all? Not going to happen.
 
Currently I have a DFI NF4 SLI, 3200+ Venice, X800XL, 2 HD, two CD roms one 120mm fan at the back. I can't afford a new PSU at the moment, so I decided to see if it was going to work with this Seasonic 400 watt 20 pin PSU that I have. I did a fresh install of Widows XP Pro serv pack 2 and it has been working great with no issues. I will update to a new 24 pin 480 watts before attempting any overclocking but for now I had no problems for over two weeks. All I had experienced so far is stability. Only out of spec I have tweaked is the ram at 2-2-2-6. Give it a try. Do a fresh install of windows with no added on cards. Only the Video card, one hard drive, and one CD rom. After you download all the latest drivers for the chipset, video card etc. then add a second drive and test it for awhile and so on.
 
I just sold my Seasonic 400watts and told the guy I will ship tomorrow. Only thing I have left is an Antec Sonata 20 pins PSU. It will be a week before I can't afford a new 480 watts. So I will give this Antec a try on DFI NF4 SLI. :eek: Whatever you do don't buy a modular PSU like the Neopower. The DFI don't work well with those.

That is not true!
The Antec NeoPower 480W works very well with DFI N4 mobos,
but being limited to a combined +12V@32A, I wouldn't choose it for a super-highend SLI rig.

new egg has the Antec True Power II 550W SLI Certified for only $89! ;)

$89: http://www.newegg.com/Product/Product.asp?Item=N82E16817103931
 
Well so far so good. Only thing this time I didn't connect my second CDrom or Floppy drive. Hopefully it will last me till the end of the week. If not I'll have to go to Best Buy and get the overpriced, at Best Buy anyway, Truepower II 430Watts ATX 2.0 PSU for $85 after taxes. :mad:
 
eh yeah that's what I figured I'd hear. Well I guess I'll pick up a new psu...I don't want to be hold back by the TP430. That TP550 does look tempting.

go with a fortron bluestorm 500wt...there only about $80 they are 24pin and atx 2.0. also you wont find a single complaint on the web about them, the general consensus is that they are kickass psu's at a damn good price
 
yeah I have really LOVED this TP430, but I guess it's finally time for it to retire to use in my dual P3 box. (haha it's currently using a crappy 200W dell psu) Time to move on, I guess. I've been trying to avoid it since I have had NO issues at all with the antec...it's been a FANTASTIC psu. Oh well...it will live on in the server.

They are nice & are in the guide for $73 & free shipping.

However as their combined +12V is less than 30A, they can not be recommended for SLI.
The nVidia recommendation is a min total of +12V@34A.The Antec True Power II 550W is nVidia SLI Certified.

they should still work for sli especially if hes going with dual 7800's because they require less juice than 6800's

EDIT: hes goin with an x850 xt so its a non issue
 
Yeah I mean this isn't a new build...the only thing I'm changing is my AX8 to SLi-DR. That's why I was hoping the TP430 would still be okay...on the AX8 it works perfectly with dead-on rails (measured with multimeter, of course) on the TP430, and I found it hard to believe that just changing mobos could really affect power consumption. But hell, I'd need a new psu if I ever chose to go SLi in the future, so I might as well take care of it now while I have this fresh paycheck in my wallet.

They are decent PSUs, but with only very basic spec compliance. An Antec TP-II will exceed spec (tighter regulation + lower noise). I'd shoot for one of those. If you're looking for quiet, then get a Seasonic S12.

The Neopower480 is a good choice also.

I'm using one, and while I haven't exactly taken a multimeter to it or anything [H] like that, it's nice.

There's a very good sticky over at dfi-street.com on power supply choices, read it.
 
not trying to take away from the original poster but, Im new to the whole Native 24pin PSU. is the PSU Native 24 pin when there is a 20+4 pin connector that comes with the PSU? and are the ones that are 20pin PSU and the 24pin adapter the ones that the newer mobos cannot use?
 
Both "solid 24-pin" & "modular 20+4 pin" are considered native 24-pin ATX.
The use of 20-pin to 24-pin adapters is usually bad & is "forbidden" by DFI for their N4 mobos.
 
well I picked up a neopower 480 today and it sure looks nice :cool: I'll see how that goes. The TP430 will now take its overkill role in my dual P3 server lol.
 
Because like I said before, I had a non-sli board before. This isn't a completely new build. Before I had the X850XT with an Abit AX8 (which I know everyone wants to flame for being via, but it really is a great mobo). But I replaced it with the SLI-DR. So I still have the X850XT. I have no intention of getting an SLI setup anytime soon...I just got the sli version so the possibility is there and I won't kick myself later or have to get yet ANOTHER board if I do want it. I have more important things to buy first before another video card (like a new monitor, more hard drives, etc.)

Mine is working properly.

3700+@2.75gig on air. Mushkin PC4000 Cas2 2-2-6-1T@1:1, 3.5v. 7800GTX 480/1.35.

Plays BF2 for hours like that.

Thanks, I wrote that PSU Guide, too.

I'm happy that it is currently working for you,
however many people have damaged their mobo & RAM using 20 to 24 adaptors on DFI N4's.
That is why DFI "REQUIRES" native 24-pin ATX & a min of 480W's for their N4 mobos.

Looks like its more of a strong suggestion, than a requirment. As clearly its not a "have to have" for it to work properly.

You did? Well good job, I link people to that thing all the time.

Again - it does not "have to have" it to WORK, but it does to work PROPERLY. :D

A native 24-pin power supply is REQUIRED for this motherboard and there is no getting around it.

need 28 amps on the 12V rails minimum imo. Built 5 of those for Pro_Engineering workstations and found out the hard way on the first machine.

Care to tell me how mine is not working properly?

Seems I am getting around it just fine.
 
Don't worry too much about it. It is a very good 'idea' to get a native 24 pin with combined 34A on the +12v though. It's really for the combined/ and total of the rails on these PSU's and the extra current that they need. Add overlocking to that, and with SLI mobos higher end cards added in SLI mode to the mix you need alot of clean power. If you notice problems later on when you overclock you'll probably know why. My PSU has 34A single rail with 20 pin and if i get this motherboard i will attempt to use it anyway just like you did.
