My System Specs

Default Power supply blew up (Smoking with Fire!)

Hello HWC! My parents computer last night apparently blew and they both stated they seen flames and a lot of smoke. There also was loud cracking noises (like live electricity) they stated. What are the odds that the motherboard or anything else is now fried? Is there visuals I can look for to see if capacitors are blown or anything? Would it be best to order a new PSU and just try first? I am going to need a new one regardless. Thanks for the help.

This was the power supply (Mushkin Volta 500W): Mushkin Enhanced Volta MKNPSVT500 ATX 12V 20/24PIN Power Supply

It would truly depend on the power supply, I've seen one do that and in the end all that was damaged was a fuse inside of the power supply. On the other end I've seen that take out an entire rig. I would try replacing the power supply and see what happens first (without say the HDD or peripherals plugged in, just 1 stick of ram, mobo and cpu)

Ok excellent. Thanks for the great help so far.

They also reported there was loud cracking noises (like live electricity) when it was going wonky right before it smoked.

Uhmm, why bother jumping the PSU? If flames shot out of it and it smells all burnt I wouldn't use it even if it worked by some miracle.

It's not even a good PSU from the beginning and chances are that the flames from the unit were from the cheap Taiwanese caps in the unit

O yes I didn't plan on jumping it, I'm just going to order a new Antec PSU and go from there.

Helps to run it off a UPS rather than directly from the wall. Especially at certain houses with lots of surges.

dont do this... if the psu went up in smoke there is absolutely no point in testing it. Sorry Kapt I hate to say this because I know you help a lot of people around here but this is a really bad idea.

Number 2 don't play with live electricity unless you are a/ skilled in doing so and B/ understand Direct Current intimately.

np just a friendly reminder for those avid tinkers for the dangers with power that you don't see can hurt you
