Wow I am really getting some bad luck. My 3rd PSU was working fine for about 4 weeks until my fan starting making loud clicking noises and my in store warranty has expired.

Going on my 4th PSU in less than 2 months. The first two were replaced in store

Now I am in the process of RMA'ing the PSU with over $20 in shipping.

I must say though EVGA customer support it freaking amazing 10 year warranty is also nice.

I will be out of a PSU for about two weeks I assume. I just hope that the replacement will not give me any problems this time. Never had this much issues with a computer than is less than 2 months old

Here is what I have been though

1st PSU was a Cosair CX750 (Bad coil whine)

2nd PSU EVGA Supernova 750G (Electrical/Crackling Popping Noises)

3rd PSU EVGA Supernova 750G (Terrible Fan Noise/Bad Bearing)

Any crackling noise from an electrical component should be treated as a serious issue, no normal operating conditions should be generating a noise like that.

I would contact EVGA and see if they will do an RMA , also find out if they will ship one to you and then you ship yours back, some companies will some wont.


Bad units happen in every line, statistically someone has to be the person to get multiple bad PSUs in a row, you were just the unlucky one.

It's just bad luck mate :(  I wouldn't recommend using the power supply if it's making a crackling sound but if you do decide to keep on using the PSU I would highly recommend that you check if you have Surge Protection Enabled in your BIOS just in case your PSU actually does kill itself it wont kill anything else along the way.

I second calling EVGA. Their customer service is absolutely amazing, and they will cross ship for defective parts.

Well my last Cosair PSU was broken for sure the guy at Microcenter even heard it the horrendous coil whine

Cracklings seems to be worse than coil whine it seems from what I am hearing as it is physical damage to the capacitors.

Guess I will be traveling to Microcenter yet again for my 3rd PSU, Prob be on Tuesday as that's when I have available time, plus I am still under warranty.

This is really frustrating and depressing. Brand new gaming rig and having all of these problems. Better safe than sorry as a bad PSU could fry all of my components and them I am really screwed. Its an annoying inconvenience but better than the alternative.

Well it seems like the noise has faded for now, the computer has been running for awhile and the noise is gone.

I switched out my surge protector with a brand new one and the noise has vanished.

Although I fear that if it was my last surge protector, it already did some damage to my PSU that will make it break prematurely.

I am going to replace the PSU anyway just in case.

Could it have been my last 8 year old surge protector? That could have caused my brand new PSU to make crackling noises, and should I replace it as it could have done some damage to my PSU even though the noise is gone now with a brand new surge protector strip?
