power supply problem s12 600 seasonic

[mrdavidpham]

Ok, I just received my s12 seasonic 600w. I plug everything in hoping my computer, just motherboard for now to see since I don't have a video card yet. The board is a DFI ULTRA D modded to SLI.

It turns on but then immediately it shuts off. The light to the motherboard is on however. I was confused as to why doesn't it turn on since yesterday I turn everything on with a Enermax 350w.

So I took out my old Enermax and plug it in and BAM it turns on! I was thinking darn I got a crappy psu but then to test it further, I plug the seasonic into another computer. An Intel p4p800 motherboard and BAM it works!

So I don't know what is going on, it just doesn't work with the ULTRA D or what?

ok I test it again on my asus sli premium and the seasonic works! And then I test it on the Ultra D it doesnt work! But then I try my Enermax on the ULTRA D and it works! So I guess the Seasonic doesn't like the Ultra D???

You know its extremely funny you posted this. My buddy and I were building his Media Center pc at work, which included a Seasonic s12, and the DFI Ultra-D. We too are experiencing similar symptoms. Now that you mentioned it, I'm going to take one of my power supplies to work and give that a shot. I'll keep you updated on the results.

I solve the problem thanks to this guide

All you have to do is changes some jumpers around and it works. I didn't expect it to be that easy! Hope it helps.

The Seasonic S12 has been revised by the manufgacturer, but apparently the new rev STILL has the same buggy problem with several brands of motherboards.

QUOTE
Here is a copy of e-mail from Seasonic, Quote: Here is our first analysis. The main problem should be caused from the +5Vsb. The peak (motherboard) voltage of +5Vsb at the monent of power on is out of the spec of PSU. The original design of the +5Vsb (from the Seasonic psu) is 2A which comply with the Intel spec. The loading of +5Vsb (motherboard) of your system might over the (Seasonic) spec. So the PSU senses the alarm and activates the over voltage protection to shut down.
END QUOTE

Somebody on this forum, I think maybe it's Kamper, raves enthusiastically about Seasonic because it has 120mm fans, which make the psu quieter. But, beware Seasonic. Apparently it's designed for Intel motherboard + Intel CPU. You can't rely on whether or not any individual Seasonic psu will work right with other mobo/cpu brands - maybe, maybe not. It's just a roll of the the dice.

hey gents

I wanted to chime in here. I've had the notorious S12 / DFI problem for a few months now. Last month I sent my PSU in for replacement.

It came back yesterday and now I have some SEROIUS PROBLEMS. I installed it this morning, double-checked the power cables, hit the on button and NOTHING.

Unplugged everything, tried again, and this time SMOKE CAME OUT OF THE SYSTEM.

Needless to say I'm pissed.

I've disassembled the entire computer and hooked the parts up to a second system to assess the damage. Apparently anything connected directly to the 12V rail got hit hard and most of the components are now dead.

The casualities are:
- DFI Ultra-D: DEAD, fans spin, but will not post with ANY PSU or processor
- Athlon 64 3500 Venice core: DEAD (this was one NICE chip too. Would roll at 2.805GHz all day long)
- 250GB WD PATA HD: DEAD (this was the drive were all my backups were stored) - literally saw grey SMOKE come out of it
- Floppy Drive/Card Reader: Combo drive is DEAD (again, saw the grey smoke come out of it as well)

The survivors:
- OCZ Gold VX 4000 (thank the Lord - this stuff would run CAS 1.5 at 250MHz)
- ATI X850XT PCI-E
- Dual 74GB Raptors in RAID-0 (was able to hook these puppies up to my 2nd system and make an image of the array contents)

Has anyone had this happen before? The Seasonic PSU is definitely the culprit, since my 380W (generic) was powering the system up until minutes before the PSU swap. What do you think my chances are of getting Seasonic to pay for the components that are now DEAD? I estimate it is between $500 and $700 worth of stuff, counting the PSU.

Damn, and I thought Seasonic was a reputable manufacturer.

 

[cantbprince]

So did i .... should i be worried i'm running the S12 600w with no probs but i do find it kinda loud...

 

[brentpresley]

LOUD? I could say a lot of things right now b/c I'm p))sed off at Seasonic, but loud is not a proper descriptor. I've never found a quieter PSU.

read the warranty...most warranties ONLY cover the PSU....good luck!!

 

[brentpresley]

Well, if that IS the case. I have the time and the resources to put the ball in play with the California State AG and the BBB.

Seasonic HAS KNOWN for a long time there is a problem with the S12 series and the DFI boards. Instead of working with DFI for a solution, they have constantly passed the buck and told their customers tough luck. There is MORE than enough evidence to at least get this heard by a judge or jury.

I've been patient and tried everything that I have been told to correct the problems. Now, when they ship a defect PSU back to me and it HOSES my computer . . . Well, I'm pissed, and I'm ready to play hard ball.

read the warranty...you are legally bound by the warranty--!!!!

The calif BBB and AG will not do didly!

They will read the warranty and thewn they will ask you...
Did seasonic offer to replace the PSU? thats one question...You will in turn say YES but...
They will say sorry no but...the warranty ONLY covers replacing the PSU...

Have an interesting time..

I've been running my DFI 24/7 for 10 months already and no problem so far. Actually, I take that back, my onboard Nvidia LAN crapped out after 4 months but I just used the Marvel LAN instead. This also happened to another box I built for a friend, the onboard Nvidia LAN died after 4 days of Priming so end up using the other Onboard LAN. I wonder if this was an isolated incident...hmm..

 

[Zebo]

My son is running a DFI NF4U and seasonic 600 just fine.

sounds like a lot of passing the buck by DFI in that last post @ D-street . They did the same with frying mem modules and processors too when thier products are in question. Personally I'd aviod the DFI rather seasonic - but looks like you need to aviod one of them.

But the Seasonic is having incompatibility issues with one mobo. Why boycott the PSU? That's just crazy. In doing research, that would lead you to not get that particular (brand or model) mobo. I have 3 Seasonic in two machines, and I couldn't be happier with them.

If Seasonic knew there was an issue with a particular mobo that is very popular, they should have corrected the issue or recalled the product instead of allowing it to kill one of their customer's computer. Atleast, that's what a good company would do.

Modify a product line for one motherboard? No. DFI should correct the issue. Not the other way around.

So you want DFI to modify their product line for one PSU? Bah, we can go on and on about this.

i thought seasonic had fixed that dfi issue with a newer revision. kinda like antec with their neo-he and asus.

I bet that PSU is hell of a lot more popular than any mobo which fade away each year and a lot more of them than PSU's to choose from. Besides DFI is not complying with the form factor spec - SS is complying.

You really are DENSE.

When the PSU FRIES everything on the 12V rail when it is FIRST installed, I would call that a DEFECTIVE product.

SMOKE was pouring out of my system.

If you bought a POS FORD car and it had electirical problems, spontaneously started a fire while parked in your garage and BURNED DOWN YOUR HOUSE, you bet FORD is responsible for BOTH THE CAR AND THE HOUSE. I guarantee you that is how your Home Insurance is going to see it and they would go after Ford for every penny.

Furthemore, if my 380W GENERIC PSU can power the DFI system with NO PROBLEMS (while fully overclocked too, mind you), why can't the 600W Seasonic? Seasonic has been aware of this problem since last July. Why couldn't they include a fix when the A2 rev was released in Sept/Oct?

There are absolutely NO OTHER psu's that have this problem with the DFI boards. None, zip, zero.

Good for you. So are about 75% of the other S12+DFI users. Unfortunately, there are a LARGE number of people that have problems with this setup.

Actually, the Seasonic does NOT always provide the full 2A that the ATX 2 spec calls for. That is the problem that these DFI boards are running in to.



Besides, this is all off the main topic:
There is NO WAY that pugging in the replacement PSU to the board should have fried all of these components under any circumstances.

And just for the record: THIS IS NOT MY FIRST, TENTH OR EVEN 500TH SYSTEM THAT I HAVE BUILT. I DO THIS DAILY AND THIS IS WITHOUT A DOUBT A DEFECTIVE PSU.
