Is my CPU dead if my motherboard had ESD protection?

iLikeVelcro · Nov 2, 2015

I had built a PC and the power supply sparked up and I had to RMA everything. Since Newegg does not return CPUs, I want to know if it at least survived that PSU spark.

i haven't had a cpu ever fail. generally everything will go before the cpu does. i bet the cpu is still good.

that is very questionable. Having ESD doesn't mean your impervious to a PSU frying and overvolting your CPU. Though it does help in certain situations IF it has been applied properly in motherboards design. Personally I have had ESD before and still had a PSU go bad and literally fused several of the CPU pins to the board. And other times I have been golden and just had to swap out my MOBO. If your really in doubt order another motherboard and PSU and find out. If your CPU works great otherwise you could return the mobo and invest in a whole new platform.

I wish i could be as lucky. Can't say I had a ton fail but it has been more then 2 in twenty something years of builds.

CPUs tend to almost never fail. If your CPU isn't fused to the motherboard it's almost certainly okay. Can't say the same for RAM or graphics cards though. There is a good chance you will have to replace those.

My motherboard was an MSI B85M-G43, and it had the ESD thing. I'm just asking if the surge would've killed the CPU, the rest was RMA'd and I don't want to buy a motherboard if I don't even know if it works.

likely not unless as i mentioned it is fused or has visible damage. But even then it's 100% for sure ok. just more likely (strong on the likely) then not. I would take the chance if it were me, assuming you see no visual sign of damage. CPUs are pretty resilient while in board. otherwise your looking at a new build.

I can see no damage whatsoever to the CPU, and there's no burnt smell, so I think its ok.

Then i would give the replacement board a shot. worse case scenario you have to do a new build, least this way you minimize the chances of having to do that. You have no control over part failure regardless.

Yeah and if it doesn't work I'll just return the parts.
