MOBO On Fire!! Can someone tell me what caused this? Pics Included!!

[everman]

I'd definitly replace the mobo, don't risk everything plugged into it.

And as a sidenote; when you smell something burning in *any* electronic device, please turn it off.

 

[Walay]

Thanks, Ya, I will definetely replace the mobo, and rma the psu.

Also, DrCool, it is not the problem of dust as the back of mobo looks pretty clean...and I do use dust blower once in awhile....

I try to tell them Lord, but they just don't listen... Sigh...

.bh.

:moon:

I got the same thing from my Antec PSU. I vowed never to use them again.

 

[jonnyGURU]

Did anyone else notice the burns on the board are at the 5V pins of the power connector?

Usually when I see this where the burn originates at the motherboard, the problem is not the power supply but something running 5V plugged into the board. 90% of the time it's a board mounted w/ an extra stand off or a PCI card gone wrong.

Any chance I can have your photos for http://www.jonnyguru.com/mishaps?

I listened, and agree completely.

then when you get tired of that one, use this.

rofl man
ensure that there is nothing making contact with the case and Bad crimps on the psu could be the culprit too.

 

[Walay]

5v huh....I will definetely look into that...as I just got a new mobo and will be getting back the rmaed ps soon.
I have couple Pci card on my comp, would be pain to try to figure which one is at fault.


"ensure that there is nothing making contact with the case and Bad crimps on the psu could be the culprit too. " Ya I'm usuallly aware of that when I install stereors and computers.

Yes you can use my picture for your website, but do not link to it! I will take those pics down soon....-_- too much hits..

 

[sharkeeper]

LOL, you didn't have a fire. That's just an overheated ATX connector caused by high resistance contacts.

Now this is what happens when the damn thing catches on fire!

Cheers!

 

[Zepper]

Whoa, sharkeeper.... Musta been a blowout LAN party! Was that on purpose or a true "accident"?
.bh.

 

[sharkeeper]

It was real and burned a shed to the ground in the process!

Cheers!

No. I don't link other sites. I always put the photos on my server.

Hmm..I had an Antec 480 True Power just pop, crackle and spark and die on me after 2 yrs...my system was fine except the floppy was not recognized..somehow it became disconnected..reconnected and the PSU went....the system was running for 2yrs with no recent crashes...

I only hope my cpu/mobo etc is ok..I have no PSU to test them right now

I just purchased a OCZ Powerstream 520 w PSU

Sounds like you reconnected your floppy drive's power one pin off. Happens all of the time. Instant kill to a power supply. Are there burn marks on the floppy's power connector?

 

[nealh]

No marks on the floppy power connector...I triple checked before starting the PSU becuase I fried a floppy on my first system build about 5 yrs ago...but then I was real stupid tried to connect the floppy with the PSU on...duh!!!

I checked the floppy over no burn marks on it...nothing on any of the floppy power connector....mobo looks ok as well....


Like I said the strangest thing was the fact when I open the case...somehow the floppy was disconeected...very weird I had not opened the case in at least 2weeks and had used the floppy to due a flash not to long before this...

anyway that floppy is not getting connected again....

On a side note, that ups might be an sps. Uninterupted Power Supplies run your box off of inverted battery power, thus "cleaning" the power. Standby Power Supplies run your box with straight 110v power and switch over to battery when needed. They don't provide any regulation. Both are sold as ups, especially the discount ones.

A voltage spike can and will get thru an sps, where a ups can stop it.

wow...I didn't know that...

so how do I know in the future that I bought a UPS not a SPS ?

Look at the discription of the unit. The Belkin that I just bought was calling itself an uninteruptable standby power supply (cheapo unit). That makes it an sps, not a ups. Inside it has a large transformer that helps maintain the power while it switches over (a ferro something or other, the name escapes me right now). My cheapo APC is a lot better than the Belkin, IMO.

Ferroresonant transformers are used on true zero transfer time UPS'. Brands such as Best, Deltec, Liebert, Sola, etc. use them. These provide true galvanic isolation from utility mains, tight regulation within load limts, and rock solid frequency with extremely low harmonic distortion. The isolation is important as it keeps harmonics out of neighboring (mains) circuits and it provides the best in spike and surge suppression. This technology is what keeps 911 call centers and casinos operating regardless of the weather.

Cheap UPS' like most APC's and similar found on desktop personal computers have a transfer time of a few milliseconds. They also do not produce true sine wave a/c fundamental power that the better units produce. Of course this is what makes them affordable! They work fine for pc's and most peripherals that can run on stepped approximated sine wave AC. Most motors will not run well at all (if at all) from them and resistive loads will overload them quicker than the nameplate rating says.

Cheers!

Amazingly everything still works, the mobo, the power, video, hd, nothing broke!
and therefore I have no idead what might have caused this burn? mobo fault or ps fault?
Is hard to say since both still works fine.

LOL

omg lol :thumbsup:

Why would that burn the board though? Wouldn't that just directly short the PSU, and either blow a fuse, or maybe a cap in the PSU, and/or melt the wires/connector on the floppy side of things? Why would the mobo be scorched in that case? I don't buy that scenario. (Ok, also, I've "one-offed my floppy drive's power connector a few times plugging things back into my full-tower in relative darkness, and the worst that happened was that the system wouldn't boot.) Hmmm.. If the floppy power was wrongly-connected, the system shouldn't have been able to boot/run at all, I would think.

(Remaining excellent summary elided for brevity.)

I find that interesting that a "consumer" UPS would have that, mind listing the exact Belkin model number? I might want to pick one of those up, my UPS is going to need replacement at some point soon.

Different person talking about a different issue. Try to keep up. The person I was addressing merely stated that their power supply died after hooking up the floppy drive. I wasn't talking to the person with the burnt motherboard.
