[SOLVED] Crackling noise from hp power supply even after getting the wall plug grounded?

[user123123]

for system reference please also check this thread of mine: https://forums.tomshardware.com/threads/crackling-noise-from-the-psu.3724960/#post-22480766


"actually, there is still some crackling noise altought very silent ones, like crackling your fingers quietly but even quieter, it either comes from the power supply or the mobo/cpu fan, and i doubt if it is about the load on the system as there seemed to be no change in frequency after running a furmark for like a minute, the crackling noises seem to appear completely randomly, like 1-3 times per minute, any idea why? again as i said, it is a hp prebuilt psu so that could give some hints?"

the first crackling noises seemed a bit electricity-y but these disappeared after i got my wall plug grounded, now it sounds like crackling of fingers but very silently, it either comes from the psu or the cpu(fan) as i doubt if there are any other moving parts in the entire system, as i mentioned, it happens like 1-3 times a minute, is this something to be worried of?

edit: actually when i listen to the pc closer, those crackling noises are still there but really silent zapping noises that u can only hear dimly when you get near the pc case seems to also exist, any idea?

Be worried and be careful.

From the referenced post:

"i grounded my socket using a shady method but atleast it works so i guess that was why, hope my psu didnt get any damage meanwhile it was non-grounded".

Just what sort of fix did you do?

My thought is that the problem is intermittent, inside the case (i.e. PSU and/or motherboard) and your "shady method" was not a real fix.

Crackling noises could be from tiny sparks somewhere. Sparks mean that there is a loose connection or some other situation where electricity is flowing across air from one point to another. Arcing. Does not require moving parts....

If you get yourself between the source of that electrical flow and ground/earth then you could shocked. May already be happening but, for the moment not noticeable.

However, the next moment could end badly.....

Not safe. Power down and unplug.

Find someone who has a multi-meter and knows how to use it and may be able to find the source of the short.

Do you have access to another PSU that can be installed for testing purposes?

i dont know if its legal to share it but i used a technique where you connect the ground to the neuter, absolutely dont use this as it is dangerous yall reading this 5 years from now on. but i really doubt if it is about the grounding thing, it was done properly and im almost certain that the problem isnt the wall plug or whether its grounded or not, but the psu, but the question is that will it brick my system or is it something minor?

also i dont have access to another psu, if i did, i would use that

No.

That should not be done. Known as a "boot-legged ground" and the consequences may be dire.

No one reading this thread now , 5 years from now, or ever should consider using the implied solution. Do not do make any such connections.

FYI:

https://en.wikipedia.org/wiki/Bootl...scription,exposed casing can become energized.

(Will concede that the wall plug or grounding may not be the problem. The PSU remains suspect.)

However you have set up/created a situation where some other electrical problem or mishap could make a bricked computer system the very least of your worries.

Get a qualified electrician to undo your "technique" and properly fix things. Do not wait.

i know that the plug itself can brick everything but im talking about the psu, i literally cannot get that plug grounded right now
