The following, although very good PSU's,
are NOT RECOMMENDED for DFI N4 mobos, as it would be very difficult to provide proper loads.

PC P&C 850SSI 850W (4X +12V rails designed for dual CPU mobos)
Enermax EG851 660W (4X +12V rails designed for dual CPU mobos)
SilverStone Zeus ST65ZF 650W (4X +12V rails designed for dual CPU mobos)
SilverStone ST60F 600W (4X +12V rails designed for dual CPU mobos)

These fine PSU's are recommended for use in EPS/SSI (dual CPU) systems, for which they are designed.

From the DFI N4 PSU Guide.

I should have one on the way soon. From what I've heard, it's actually a higher wattage PSU then as advertised, but to compensate for the potential voltage drop at higher loads due to the modular interfaces, they "under-rated" the unit as a "600W."

That's quite an assumption to make about a PSU nobody's tested. ;) It's a quad-rail PSU, but when using with a single CPU, you use a 2x2 connector instead of the 2x4 connector. The 2x2 connector actually combines the 12V1 and 12V2, so it is more than enough power for the CPU. Since the drive Molexes are split off onto 12V4, that 13A on 12V3 is pretty much wide open for PCI-e use. The maximum combined continuous (not peak) load for the 12V rails is 42A! So there's lots of overhead to load up multiple 12V rails simultaneously.

I can hardly wait. :D

No it is very logical & follows the clearly defined trend of problems with ALL of the 4-rail SSI/EPS PSU's,
you know very well what these were designed for & it wasn't 99%+ of PC's.

And wasting 2X 18A rails on a 100W to 150W CPU is just stupid!

Recommendations will always be made based on the best available information &
lots of caution, as I have no intension of recommending a very expensive PSU,
for an application that is best served by one costing far less.

Dave ;)
 
Then why did the ST65ZF get moved to the recommended list when it's the SAME POWER SUPPLY only not modular?

Is this one OFF the list because it's modular? That's what set me off. I put this same power supply through hell when it wasn't modular. Now it's modular and it's not recommended because it's a quad rail with SSI/EPS connectors?

They're trying to satisy a larger market base than JUST gamers or JUST servers.

And "you know very well" that two, three or four 12V rails are not additive no matter what PSU you have. If you have a 12V rail that's just available for CPU's, that's not going to take capability away from other rails.

So what if they have 18A available for just a CPU? Maybe an 12V/18A MOSFET doesn't cost anymore than one with 10A. It doesn't matter. What matters is the bottom line power the unit can put out to run ALL attached components.

The "biggest problem" is the PC P&C 850W,
I have several people who purchased thesefor DFI N4's & the +12V rails are unstable in their "low +5V demand" rigs.
So a decission was made to recommend against all 4X rail SSI/EPS PSU's for DFI N4's.

No single CPU PC needs a 600W+, 4-rail PSU anyway & trying to use one causes more problems than it solves.

Sorry, I know it is not fare, But I just don't know what else to do for the n000bs with far more money than brains. :rolleyes:

Any suggestions would be appericated.
Thank's
Dave ;)
 
Come on Dave... We ALL have more money than brains in here! That's why we have 3GHz CPUs, 2GB of RAM, a pair of video cards and a Zlaman Reserator (and there's others with even more!!) :)

Hell.. I see PC's twice mine and all the people do with them is surf the Intraweb!!!

If someone wants to spend even $500 on a PSU that's modular, has windows, neon lights, etc. I figure let them. It's their money. As long as it's a good power supply.

That's why I don't mind if someone says the Sintek may not be worth the money, because it has all of the bells, horns and whistles and may only be a tad better than mediocre under the hood for over $100. But Silverstone has proven to be almost as good as PCP&C in many respects, has a modular power supply and we all know that ST65ZF power supply did a steady 44A load on the 12V rail and the voltage never even budged.

Here's a power supply that can likely handle the exact same load, is modular.. and is ONLY $165. $165. Look at the price of any Turbo Cool 510W (which I'd take this Silverstone over) and up or anything else around $165. That's actually a GREAT price!

EDIT: As for the high 5V crossload demand.. well.. we already went round and round with that. But given the results of SPCR's "real world" loads and how low they found the 5V rail, I'll be testing with the 5V rail even lower (as I did when I load tested the ePower/Tagan/Topower modular posted here: http://www.hardforum.com/showthread.php?t=952639&highlight=Tagan )
 
Over at DFI-Street, I must be 100% sure, that a PSU has no-issues with DFI N4's, to put a PSU on the "A" list.
Even the "recommended list" requires great care given how finicky these DFI N4's can be.

If you would like to test these (&/or other) PSU's on various DFI N4's, I'll see about getting you some mobos.

Thanks,
Dave :D

Someone would have to give me one. :)

I need a bench rig anyways. I'm always using my customer's machines and one of these days... well... let's say I've been lucky so far. ;)

Did you ever notice that the #1 PC running 3DMark2005 on FutureMark's community pages is a DFI... powered by a Silverstone ST65ZF? http://www.futuremark.com/community/halloffame/ ;)

Well, if you have people that actually are in posession of the PCP&C 850W and are experiencing problems due to a low 5V load, then I understand completely.

But I don't think the Silverstone falls into that category. Here's a rig with dual Athlon64 X2's, a pair of 7800GTX's (hell of a 12V load already, right?) but only a single hard drive and a singe optical drive... all running on a quad rail Silverstone ST60F. Hardly any 5V load at all, but perfectly stable: http://forum.coolaler.com/showthread.php?t=104917 ;)
 
Alright you win, I will just isolate the PC P&C 850W. :cool:

EDIT:

Done, your beloved Silverstones are backto "recommended" as is the Enermax (851) 660W,
only the PC P&C 850SSI is directly "Not Recommended for use with DFI N4 mobos".
