****OFFICIAL**** Dfi Nf4 Psu Statement

All the new DFI NF4 based motherboards support both 20-pin and 24-pin
power supplies. It is recommended that a higher wattage power supply
with the 24-pin connector be used for utmost stability. Combined with
the onboard power regulating components and the flexible BIOS options,
these new DFI boards can deliver performance without compromising
stability!

Best regards,

The above is an official statement issued by Vivian from DFI, whom I have been in contact with due to various things.

This information hereby comes from a DFI REP. I hope this clarifies many things. If you have any further questions, I am sure DFI PR and TECH Support will gladly help!

Regards, David

kewl

but very weird...

Angry_gamez at dfi-street told VERY clearly DFI doesnt support any 20-pin psu at all, even not the good ones...

i thought that was a lil strange allready...

guess its a lil the same like he sais that no waterblocks will ever be made for the dfi nf4 NB :p
and like he sais that the dfi nf4 sli-d cant be for sale yet (while people report buying em at multiple places allready...)

dunno who to trust anymore... :(

have a 430W Antec 20-pins psu atm with 20A @ 12V

so it would be close anyway allready...
but still an OCZ 520W is kinda expensive, especially since that antec aint that old and was expensive too :/

This came from Vivian via public relations. Please talkt to them if in any doubt.

so does that mean i can just plug the 20pin connector in the board or that i need a 20->24pin adaptor ?

use 20>24pin adaptor!

Does this mean that you can use a 20pin PSU for overclocking, and it should be stable enough?

From what I know a 20 pin can be used without an adapter, as written elsewhere on this forum.

20pin can be used on the 24pin board without using adapter (4pin unconnected), but it`ll comes to unstability... i`ve try it on A8N-SLI deluxe + Antec TrueControl 550W... It was very unstable, until I replace Antec with tagan 480W...

well at least i can give it a try without risking to damage my board

@juliette: why did you change your avatar to this black hairy thing?
cmon use a.lima again :D

[edit] wow that was quick :D

i'm using a ocz with a 24-20 pin adaptor in my asus sli, doing that so i can use the 20-20pin dual psu cable coolermaster supplied with my stacker case, so only 20 pins going into motherboard and no issues doing that at all.

Just only plug the 20 pin connector into the board is fine. I am using Antec TC550 to power up my DFI NF4 SL-D. :)

The benefits of using a 24 pin PSU will be similar to using the 12V connector.

Does the DFI use the 8 pin 12V connector too?

If you aren't opposed to doing so, give Antec a call and tell them you just bought an Abit AV8 which is experienced looping reboots :) They will RMA you the new model (with 26A I believe)!

Angry games might have said what he said. I am aware of AG's concern, and therefore i contacted Vivian from DFI. Her information is as precise as could be i believe, and thus you should not be worried about anything :D

Now. How can I show you I am not cheating by just plugging it into the socket without powering up the system? :p:

the 4pin 12v connector is next to the atx-plug.
if u meant that.

I have a Enermax 460W 20pin and i must say it quite unstable when plug in the SLI-D

With 1 6600GT :
12v = 11.88v
With 2 6600GT:
12v = 11.77v

I will buy a convert to 24pin next week and see how far the PSU can handle

From PC Power & Cooling website:

T51ATX

http://www.xtremesystems.org/forums/...id=23471&stc=1

T51SLI

http://www.xtremesystems.org/forums/...id=23472&stc=1

it looks like the 24pin has only extra 3.3v/5v/12v/GND wires.... everything else is exactly same as 20pin.

so probably STRONG 20pin PSU (high amperage) will be enough to power up SLI board.

have u tried ocing it with only 1 video card? is that more stable?

@bachus_anonym:

strange, according to these schemes Alexwai would have plugged his atx-plug exactly in the wrong side of the socket (connecting +3.3 to +5 and so on)

Yep , but it still unstable

W/ my Neo2 , my A64 3200+ can run stable 24/7 @ 300x9 1.6v
but w/ SLI-D , just only @ 280x9 1.4v , any higher setting comes with bad result

:D Check Your SIG - "DFI DLI-D" sounds like a new NF5 chipset......... ;)

:toast:

I would deff get a 24pin psu. with the power the mobos are useing now, the extra 3.3, 5, 12v lines into the board should help alot.

I dont know whay they just dont make a eps 12v plug or take use of the Extra Aux plug most psu's still carry.

xs64: Did you mod the psu or just run stock? maybe try upping the lines and see how much draw the mobo and cards take.. your reading the voltages from a multimeter right?

im anxious to see ur results with an atx2.0 psu!

when does it arrive? :D

I dont know how to mod the Enermax psu , seems it dont have the senseline like the Antec power 430W . And i read the vols from the SmartGuardian soft :D

Lucky man

I have Tagan 380W with 20pins.
Is better to use 20 pins in mobo or use adapt 20-> 24pins ?

Thanks you !

I'd say its about the same. Very often (depending on adapter), the use of the adapter defies the purpose of the new ATX standard.

:D If You guys spend a lot of money for mobo and most of all 1 or 2 SLI cards I think You want to max out Your system, then go for a 24 pin PSU like OCZ powerstream.

There are different opinions about that PSU but I use it for a long time without any trouble and it contains a 24->20 adapter for use on all 20 pin mobos.

:toast:

Alexwai whats ur experience using a 20pin psu?
do u have problems with oc or stability too?

380w psu i dont think will be enough for a sli mobo :|

of cource it will...problem will be if it is enough for 2*6600GT :)

still not sure if i understand this 20/24 pin statement korrekt...i know it WILL run with 20 pin in it.....

but if you dont have a 24 pin what is the best solution...
1. adaptor
2. 20 pin + 4 pin p4 cable
3 adapter + 4 pin p4 cable

??????or a 4th solution. somebody blow the smoke away and let us see the light :)

I'm liking my 600w powerstream so far, connects to anything out there :D



Fragman - #2 wins because the adaptors increase the resistance of the wires thus reducing voltage and current handling capabilities.

Well said STEvil, however it depends if the adapter really fu´lfills its intended purpose and the 4 extra wires are not duds (i had that).

I must say i like the OCZ so far :D

I'll try an Enermax noisetaker 600 W. Hope it will be good :) , any experiences?

and i order the antec true 550w 24pin 36a for my dfi, i supposed to be more then enough (:

No adjustable pots there..

Steve and Jul -

I've been trying to get a clear answer on that question for about 2 weeks...Thank goodness you finally cleared it up.

So in all reality...use the normal 20pin I have on my psu and the P4 4pin (square) plug as well...gotcha. It's sooo much appreciated.

You think my fortron's going to hold through this next upgrade? I know a lot of peeps have the same psu...I hope it can make one more round before I upgrade...whaddya ya'll think?

I'm shooting for an ultra-d, venice, and x800xl (whenever all the buggers are actually available :) )

Welcome ;) Also thank DFI for finally giving a statement ;)

Very good indeed for my Antec TC 550. Basically, as my understanding, two of my friend use only Antec True Power 480W, they have never complained about the stability and OC issue. but, the fact is that they are still using the old PCI display card (including me), So I am not sure whether there will be some issue after using 2 PCI-e.

I was thinking bout it too but then I decided to take an Enhance 520W, it has stroner 3,3 and 5V raila ad a 24 EPS plug.
Never regreted it. The Enhance is a monster!

Who makes the Enchance? Never heard of it :confused:

:D Every release of any hardware is beeing followed by a couple of recommendments for the other hardware - so if You guys are not sure what PSU to buy just ask DFI - maybe they recommend one for their "latest trick".

600 watt noisetaker is native 24pin. I think the 5v and 3.3v rail is plenty strong. We dont really need a ton of AMPS to power the memory.

seen this thread for a while and i have to say it's kind of funny that the title states:

*****oficial**** Dfi Psu Statement

how OFFICIAL can a statement be when it's spelled oficial?

hehe I noticed that too. I couldn't take is seriously either.

I told Kazoo to change it, however he expressed his (justified) uncertainity whether this truly is an official statement. Hopefully it will be cleared out soon enough :)

Should have told DFI to OPP paste this, it would have been held in much higher regard.

20 pin connector power supply works perfectly in my case. Brand el cheapo AGPB 450.

Nope, There is a 8 pin 12V plug too. That is the 4 pin one. Well, I guess one more 12V rail is still a little better.

Just messed around with my DFI, OCZ VX in Windows to run a locally developed benchmark (doesn't really matter what it is) @ 273x10 1:1. Of course, this was far from rock stable settings.

Cooled by subzero air from outside (CPU @ 10C idle, Chipset @ 8C), voltages were 1.78 for CPU (1.45x123%), 3.6v for the VX, 1.8v for the chipset.

I'm using 20pin PCP&C vanilla 510W model, so the 20pin PSU's obviously work quite well (and I noticed that I even forgot to plug in the additional molex). Other hardware was pretty much limited, though: Voodoo3 PCI, 80Gb IDE HDD, a CD-RW drive and a Floppy.

Don't know, though, whether with a 24pin PSU I wouldn't be able to run higher because I'm having trouble to run Prime95 and Superpi stable even at 245 htt.

Just shared my experience.

The way I read this is that you can run the DFI NF4 mobo with a 20 pin plug or a 24 pin adapter plug. I am using an adaptor myself.

It also says if you want stability to use a 24 pin PSU. So what's with that? Should you be excited you can run an unstable mobo?

Just come right out and say - "Your system won't work worth a "HOOT" without a 24 pin psu.

I also don't think they are only referring to SLI boards. The statement reads - all DFI NF4 boards.

I wouldn't call my system stable -

Do I need a 24 pin psu??? I'm hard headed - I need a specific yes or no answer. :D

Don't know if some of this is repost:

The 24 pin connector in dfi nf4 will work very well with 20-pin, in fact i'm using one. When unstable with 6600GT the extra molex power on the board must be connect, even with 1 6600GT. At least for me it helped alot. Especially if you're having BSOD's in 3d while primestable.

Using 20->24 pin is pointless because the extra 4 pins are each one connect to it's correspondent(3,3v,gnd,12v,etc) to the one in the normal 20 pin connector. So you're doing nothing with a 20->24 adapter.

Maybe 24 pin psu's will be more stable, because they have better rails, or more, that can supply more power, but that's it. A good 20pin psu will do the job.

Already tried a 520w ocz 24pin compared to my bequiet 520w and noticed no apparent difference.

Thanks for this info!!

So your saying - just don't use the adaptor and plug the 20 pin connector directly into the mobo 24 pin plug??

Yeah
