This is a Quote from Angry Games @ DFI Street:

(you are on your own when using a 20-pin power supply.

DFI no longer will support customers who do not adhere to the minimum power supply requirements.

if the board has a 24-pin power connector, then you must have a true 24-pin power supply.

not a 20-to-24 pin adapter

not a 5,000,323watt 20-pin with 80000 amps on the 12v rail

a true 24-pin native power supply.

period.

there is no argument anymore on this subject.

if the board has a 24-pin power connector, and we state (as we have) that you need a true 24-pin power supply and that a 20-to-24 pin adapter does not work and is not supported, then you need a true native 24-pin power supply.

no arguments

no trying to tell us we dont know what we are talking about.

period

you only have a 20-pin psu? a modded 20-pin psu? a 20-pin psu with a 24-pin adapter?

you are not adhering to the minimim specs required by these boards to run. this means that any problems you have while not adhering to the minimum requirements will result in you being told 'you need a 24-pin native power supply of at least 480w' and that is the only answer you will receive on your problem until you meet the minimum requirements.

sounds harsh?

we don't tell you to put a 24-pin power supply in just to make you angry and see you complain about how you have to upgrade your power supply.

we tell you that you are required to have a 24-pin 480w power supply because that is what is necessary.

if you want to argue about it, by all means continue arguing about it.

but you are not meeting minimum requirements and will not get any answer other than 'you MUST have a 24-pin native 480w power supply to run these motherboards and that is your problem so please upgrade to a minimum 480w 24-pin power supply'


not much else to say on this subject.

i'm tired of some of you who think you know more than our engineers continuing to argue that we have no clue what we are talking about and you can skirt the minimum requirements.

follow the recommended guidelines.

period).

I wonder if Angry_Games was smiling while he was typing that. :D

I bet he was smiling:D

Good artical! They mention the 20 to 24 pin adapter causing alot of heat at the adapter itself. Mine is cold as ice. :cool:

I own an Ultra-D
I have an Enermax 470W 20-pin, running the system on the signature

Now slightly overclocked to @2250

Was using an Enermax 460w 20 pin PSU with 33amps on all rails but listened to advice & got OCZ 520w PowerStream which didn't do SQUAT!!!

Well, I'm exagerating a bit as I was able to run 11x220HTT with my 2x256MB BH5 whereas before my rig would turn off when I set it to 11x205HTT...

Although I can run 11x220HTT with tight as timings in Memtest for 44 hours or 254 standard tests, Windows keeps on rebooting, BSODing or turning off on me when idling or if running Prime95...

So, overall I reckon it was a waste of money switching to a 24pin PSU...

DFI says not to use adapters? My thermaltake 560w came with a 20pin to 24pin adapter, figured that'd be just as good, but I don't even have a DFI board, my friend however does have the Ultra-D board with 1gb of kingston hyper X not OC'd and a 3000+ Winnie running stock with a X800XL and he's using a 20pin and hasn't had a problem yet. He doesn't even have the floppy connector right above the top PCI-E slot plugged in but I figured it'd mainly matter if you were running SLI'd cards. The X800XL doesn't even have a power connector to it like most of these newer cards

:rolleyes:

D20Ls fine :D

Moving SD 3700 in tomorrow to see if all the bells and whistles help (OCZ PSU + WC) :shrug:

Im running the system in my sig with an antec truepower 460 with no problem.

Yea I read that anantech thread and it didn't talk about not having a power connector on the PSU.

I guess I can't cancel my order for my 24pin PSU then :-( oh well.

So to me, its "not" a 24-pin PSU then...hopefully it doesn't blow up like DFI says :rolleyes:

No not at all. I was going to say how rude and juvenile the post that Angry Games @ DFI Street made was but then I thought I would just let it go! After all he is just a kid! :rolleyes:

Running my NF4 Ultra with a 20-pin Enhance 460w psu....A64 3000+ SPAW at 2700mhz, no issues whatsoever:)

Honestly, I think that AndyOCZ was mistaken about atributing failure of those OCZ EB sticks to the PSU, only because it had 20-pin connector. And that resulted in "sort of" too harsh response from Angry Games, in my opinion.
The only difference between 20-pin and 24-pin is four more wires, that's it. Those wires come out from the same "pack" that the rest of 3.3v/5v/12v. They don't have some separate circuit that they're part of.
Look at the pics I attached. This is the inside of 24-pin PSU. You might notice there are some separate wires soldered to the board, though. Don't get too excited :) They are for SATA connector :)

The whole issue with PSUs for NF4 boards is not the 24-pin that is needed but a solid, high wattage PSU with about 30A on 12v rail.

EDIT: I also think, that there was a good reason behind putting additional molex and FDD connectors on the board. Maybe DFI put it there in case some folks would not like to switch to 24-pin too fast and still use their 20-pin PSUs? I would think so, as ATX 2.0 was bought up for PCIe support. So even If one has GOOD 20-pin PSU, he could still use it with PCIe video card. To be safe, just plug extra molex connector into the board and voila! This would provide additional juice for PCIe slot, instead of those extra 4 pins... THat's just my thought, though... :)

This is just what I was looking for soom good inside pics of a 24 pin power supply!! Hey wait, that is a 20 pin power supply with a 4 pin is it not?? This board uses a 24 pin and a 4 pin and a molex as well as floppy conections.

That's 24-pin PSU with 4 pin connector that you can detach from the rest ;) In case you still have a 20-pin mobo .

Will thats great! Thats the clearest evidence I have seen yet. Thanks for the pics! :clap: What power supply is that?

This is ATX2.0 compliant Allied 450W 24-pin w/ SATA connector. Very cheap PSU, but still capable of powering my everyday "internet" rig: AXP-M @ 2.7GHz 2.15vcore/3.5vdimm + 2 HDDs + 2 optical drives + flash card reader :D

I would not use it for DFI NF4 board, though. Too weak on amps on 12v rail for my taste ;)

http://www.xtremesystems.org/forums/...id=29773&stc=1

I'm pretty sure that other 24-pin PSU are "refreshed" in the same way. I would love to see some guts of OCZ's or PCP&C's 24-pin PSUs, though ;)

I've been using my old PC power & cooling 425w deluxe with a 20 to 24 pin adapter and have had no problems yet. But I do plan on upgrading to a larger 24 pin for Sli someday, I just dont have the extra cash right now.

My rig runs just fine with the 20 pin / 24 pin adapter. As soon as I can find an SLI bridge to buy I'll get my 2nd 6800 GT and try to run SLI. I am guessing that will be the straw that breaks my SilenX's back. I almost expect it to be unstable / not boot and be forced to get a noisy PCP&C 510 SLI. Is anyone running SLI with 6800 GT's / Ultras with a 24 pin adapter?

So I can provide power to PCI-E with the molex plug w/o needing a 24 pin PSU??

I have a Enermax 365 psu and my g-card is just a 6600GT so that should provide enough without needing a new PSU right??

I'm using an Enermax Coolergiant 480W 20pins PSU with a DFI NF4 SLI and a 6800GT, any problems by now... (3 weeks 24/7 at 270x10 1'5V).

Could I try to set the jumper to 5V? I have a pair of mushkin level II waiting for some voltage... they are at only 240 2-2-2 at 3'1V (3'15v real), i need pooooower!!!!

No, 20 pin is just fine.
