solved ATX 12V Roasted MoBo. Why?

[MrDevanWright]

My computer was randomly freezing, then wouldn't display anything. Assumed it was the CPU when troubleshooting, to then discover the smoked-black 12V line during disassembly. Any suggestions for why this has happened or what I can do in the future to hopefully prevent this?

 

Windows 10, M3970AM-HP AMD 970, FX-8350 (125W), GT-780 (250W), Thermaltake Smart 700W.

Loose or oxidized metal contacts inside the connector can cause the problem you had

 

also, what board, cpu and psu are you running?

any overclock happening?

might also be your cpu pulling to much power

Even if that CPU is officially supported on the mobo having only a 4pin connector for a 125W CPU is a bit "light" in the first place. That plus the fact it would be close to 10 years old and oxidised/degraded all the while, not really surprising.

aaah, havent seen the "fine print" ^^

yup, that's not really surprising indeed

Got it. Old AF and probably pulled too much with only 4 pins. No over-clocking as it's a pre-built with very limited BIOS, but this is the max CPU officially supported by the MoBo.

 

I assume the MoBo is gone so I'm in the process of trying to find something else. However, if I re-terminated the damaged 4-pin, would you trust the less-than-year-old Thermaltake Smart 700W to be in working condition and safe? (I am looking to get a replacement through Thermaltake ERMA, but I don't have high hopes)
