NF4 Expert will not cold boot- psu issue?

Recommended Posts

This has nothing to do with DFI or your motherboard.

 

If changing the PSU resolves the issue, it is not the motherboard.

 

If changing the load on the rails resolves the issue, it is not the motherboard.

 

If fixing switch bounce for the PSU circuit resolves the issue, it is not the motherboard.

 

 

What if you have the same problem with multiple power supplies and two different expert boards? Then you switch to an ASUS A8N and you no longer have the problem with any of the power supplies? Is it still not the motherboard then?

 

I've come to believe that you are a cult member whose only purpose is to confuse the poor users who come to this forum expecting support for their MB problems.

 

If you are done with this topic, that is fine. Let the users discuss the problem and stop posting your uninformed nonsense over and over. It only confuses people looking for answers that actually address their problems.

there is not jumper there is a dedicated power button on the expert board and yes mine does it with that

 

Mine stalls too when I try to use the power on button on the board.

Just like the Seasonic cold boot issues that occured with the other DFI NF4 boards.

 

http://dfi-street.com/forum/showthread.php?t=17916

 

That thread got closed at a stage simaler to this.

 

DFI said it was not their board at fault, but a power supply issue.

 

I don't think I've heard so much bullsh-t in years. :mad:

Roadie,

Deleting posts is a desperate measure.

I'm sure you are tired of hearing about this problem and I would be tired too if I was in your position.

I see no use in posting more about this subject. This is going nowhere.

:cool:

My position as a moderator on this forum has nothing to do with the facts as presented.

Then why don't you refer back to the exact position Seasonic took on the issues.

They threw their customers under the bus blaming the motherboard. But isn't it a little funny that many forum members replaced their PSU and haven't seen another problem?

 

You guys with selective amnesia need to pay attention to the information as presented. The facts don't lie!

Try the fix for "switch bounce" which is the obvious next step.

 

Use the search function for the instructions.

I can honestly say I was on the verge I trashing this motherboard a few days ago, after going through one Powerstream 520, which was RMAd, the motherboard was RMAd, and spent countless hours calling friends and even friends of friends that have PSU capable of running this motherboard. I was at my wits end and about to give up....Until

 

The OCZ Gamer Extreme 700W PSU, yes its nearly the cost of the motherboard itself but it actually works its amazing, when I got it up and running I was able to turn the thing off and on all I wanted, so I did, about 10 times, I would power it up do a few things power it off, come back a view hours later and power it up.

 

I was very skeptical that it would actually work but it does, I even had the pleasure of try the 600W version that works flawlessly as well.

 

I think its an issue of the motherboard wanting something that at time wasnt available, the PSUs were simply not ready for the amount of power consumption, or the way the motherboard utilized the available power, after dealing with the issue since early February, and now 4 months later, this is the final solution...

I went through the same thing you did. My gamerextreme 700w works flawlessly also..

I have the cold boot problem with the "EZ touch switch" on the MB. I am pretty sure that no one has addressed how to fix that problem on this site. Please post a link if you can find one.

Actually, you are totally misinformed. The startup +5VSB of the expert is out of spec with the ATX 2.2 specification. The facts don't lie! Facts will set you free!

 

If you don't believe me, read the spec yourself:

 

http://www.formfactors.org/developer%5Cspecs%5Catx2_2.pdf

 

Bottom of page 21:

 

5VSB is a standby voltage that may be used to power circuits that require power input during the powered-down state of the power rails. This power may be used to operate circuits such as soft power control. It is recommended that the 5VSB line be capable of delivering 2 A.

In his enlightening first post of the thread, Ex roadie says the following:

 

The Expert board can draw more than the rated 2.0Amps on the 5VSB line. But! If the Expert board was the only point of failure, no power supply would run it properly.

The whole reason for having a spec like ATX is so that the components work together. Clearly, since it is the MB that deviates from the spec, the fault here is with the MB. It is totally illogical to claim that since some power supplies work with an out of spec MB, the problem cannot be with the MB. Sometimes a component in a system will fail but the system will still work. Does that mean that the component didn't fail? No, of course not. Where is your common sense?

Once again, the facts don't lie!

The "EZ Touch" switch is in-line with the power switch circuit on the front panel connector.

 

There is no physical difference between the two.

 

Please see the very first post in this thread for the switch bounce fix.

 

Just remember that modifying the circuit has nothing to do with the motherboard its self since the power on circuit is part of the power supply. The board simply provides a circuit path. That's why you can "jump start" a PSU through the ATX connector.

 

For those that continue to blame the motherboard please re-read these posts...
