DFI Recommended Power Supplies (UPDATED October 20th, 2006!)

[red930]

The minimum recommendation is for a 480W native 24pin PSU.

hi, does all this mean that the PSU i JUST purchased is no good ??

i'm asking because i don't think it is 24 pin..

As said above return that one.

 

These are fine.

 

Type-R series - well known to any racing enthusiasts, Type R represents "Racing", by using original manufacturer's platform, and then enhanced to its maximum output.

Because DFI said so. Period.

 

But really, the increased power demands of the motherboard and peripherals along with the seriously over-rated power claims of the vast majority of power supplies.

 

The nF4 chipset and the specific demands of the design require more than the average PSU can provide. By specifying a 480W 24pin PSU they are helping you avoid problems.

 

These requirements come from the guys that designed the board. Ignore their advice at your own peril.

 

Maybe I am more stupid than usual today and I am probably missing something here because no matter how I look at it, it does not look good.

 

Please bear with me:

 

Are you saying that DFI published a new set of requirements, and people who bought the boards in good faith based on the the requirements that were in effect at that time will not be supported unless they invest additional hundreds of dollars for extra hardware?

 

What about people who bought their boards from places that will not accept them back unless there is something physically wrong with them?

 

I am not a contract lawyer but it still does not seem right to me.

I also do not have a degree in marketing but it still looks like a strange way to do business and treat your customers.

 

Since DFI probably has both working for them, there must be something wrong with the way I understand the situation.

 

Now, about the wattage requirements.

 

Are those based on the advertised specs? Because we all know how some manufacturers love to overstate everything.

 

Again I am probably missing something and I'd be happy if you set me right but do you mean that if I have a 24-pin Seasonic PSU that is 80% efficient under max load, I'll have to ditch it and either buy a peice-of-crap unit that will proudly proclaim "500W" but in reality may fall way below at actual operating temperatures or shell out mucho dinero for a high end supply that will go under-used?

 

No, I am not an EE but am I wrong assuming that a brand name 430W PSU will deliever more "juice" in real life scenarios than a no-name unit that uses the cheapest available components an offering "30 days limited warranty" but has a sticker saying "480W" on it?

 

Saying, in efect, that "the minimum requirement is advertised 480W" regardless of the actual performance (no exceptions!) and denying support to those that do not adhere to these post factum requirements, is something I have some difficulty grasping.

 

I may be totally wrong here, I sure hope that I am.

If so, please educate me.

 

Best regards,

Alex.

i agree with Alexo, it does seem kind of odd to say in a forum that we all suddenly have to go buy psu's with 24 pins connector, i didn't see that requirement anywhere on the package manual or anywhere else..hmm maybe im just blind or dumb. Can it really be that bad i mean my psu for example should be pretty stable, but the sole fact that it doesn't have 24 pin atx connector makes it not compatible? this again, seems strange...why is this necessary?

Guys,

 

I can not and will not argue about legal aspects of any issue since...

 

Specifications are subject to change at any time.

 

is kind of obvious.

 

DFI has published the requirements to get and keep your rig running with the minimum of problems. You can choose to accept these requirements.

 

The ATX 12V 2.X spec has the added 4 pins on the connector to provide additional power required by the inclusion of the PCIe slots therefore a native 24pin PSU is required.

 

Additionally, the manual published in PDF format and available at the website "should always be regarded as the most updated version."

 

That comes directly from the PDF version of the manual on the web site.

[davidhammock200]

I'm sure in the fine print somewhere you will find "Specifications subject to change without notice".

 

DFI is in the mobo business, not the PSU business & leaves the brand up to you.

DFI has discovered that non-24-pin ATX PSU's & PSU rated under 480W's are causing alot of problems.

This new PSU spec is intended to help people, not to hurt them.

Alexo what are your system specs? :confused:

It doesn't tell you on the package label that you need a keyboard or that you "must buy" a PCIe video card either.

 

If you attempt to power the RAM from the +5V from a 20-pin PSU, it is likely that it will kill your RAM, mobo or both.

ok well goddamit ( sorry but this is kinda annoying have to go get a new psu again, and wil l get my money back for the other but with -10% cus it has been used) but i guess its for the best..so should i get

The Emermax 600W (#701) would be my first choice leaving lots of room for future upgrades & it is SLI certified.

The OCZ PowerStream 520W would be my second choice, it has 1% regulation, adjustable rails & a 5yr warranty.

It too will leave plenty of room for future upgrades.

The Seasonic S-12 500W is an excellent choice also & is extremely quiet.

The Fortron Blue Storm 500W is "ok", but leaves little room for any future growth.

 

I love OCZ & they PWN customer service.

ok thx.. what about this though: (the modstream) its a bit cheaper and heard its a bit more silent than the powerstream...

http://www.edbpriser.dk/Listprices.asp?ID=123201

??would it be sufficient?

For non-SLI it should be fine. :nod:

Hello ExRoadie,

 

I can not and will not argue about legal aspects of any issue since...

 

Specifications are subject to change at any time.

is kind of obvious.

 

DFI has published the requirements to get and keep your rig running with the minimum of problems. You can choose to accept these requirements.

No argument from me.

 

But, there is a difference between recommended (as in "get and keep your rig running with the minimum of problems") and required (as in "you will not get support otherwise").

 

I am all for DFI to update their recommendations continuously. In fact, I think it is a very good thing that they do.

 

However, it seems to me that they are updating their requirements and threatening to withdraw support from people who bought the boards (based on the information that DFI supplied at the time) unless they upgrade.

 

Leaving the legal issues aside, it would be morally wrong.

 

Now, as I said above, it does seem somewhat illogical so I humbly request the DFI people to clarify.

 

My setup? I'm buying components right now.

 

Already got: DFI nF4 Ultra-D, 2x512MB OCZ PC3200 Gold, AMD64 3500+ (Venice, planning to OC), Audigy 2 ZS

Planning to get: ATI X800 XL (or XT if a deal works out), BenQ DW1640, some sort of SATA 7200RPM drive (liquid bearings), replacement HSF (Zallman?) and a TV capture card (ATI theater 550 pro or Haupage 150).

 

Before today, everything I read suggested that the SeaSonic S12-430 should have no problem powering this system.

i just happened to buy an Enermax Noisetaker 600W ATX 12v v2.0 PSU. This should be fine right? says SLi on the box, and everything on the box seems to point that I got the correct PSU ?
