My PSU produce an electrical noise when I tried to turn on my PC, the noise will not gone even my PC is off. I need to turn off my psu (using switch on the PSU) and turn it on back to completely remove the noise, but when I tried to turn on my PC, the noise come back again. First, I don't really care about the noise, but after a few days of usage, I can't turn on my PC, so I turn off my PSU and wait a minute then turn it on again (the noise gone since i turned my psu off). When i tried to run my PC, my PC won't start instead the noise come back. So, decided to RMA it again, but I got the same issue again and this is the third time. First, they don't produce a noise but after 2 days usage, they started to make this noise and i can't turned on my PC, sometimes i can turn my PC but I need to turn off the psu for 6 hours or more then turn it on. Are there any solutions for this? I am already tired to RMA this thing and got the same results. Thank you

My PSU is Muscle Power Thor 760

If the Xigmatek unit works then it's 100% the fault of the Muscle PSU. So yeah, basically it sounds like they keep sending you a unit with problems, probably the same one. When they get it it probably actually works for them the first time (like you said it works once in a while, when it's off for a long time) so they probably think, "This kid doesn't know what he's doing, the unit is find. Just send the same one back."

Do you have a source for that? I'm not denying it, I just would like to know. 😉

Also, power supplies don't have inadequate power, because power supplies will burn or shut off from protections long before a power limit is hit, making "running out of power" or "not having enough power" an unrealistic scenario in computer switchmode power supply applications.

Edit: Yep, it's Seasonic it seems.

It seems like a foreign PSU. Are you sure they are not just sending the same unit back to you? Also, you said your PSU will not turn on, then you say "I need to turn off my psu (using switch on the PSU) and turn it on back to completely remove the noise" so if it never turns on how did you turn it off.

In those brief moments when your computer does indeed turn on, can you boot to Windows without eventual problems? Has this problem always happened?

Perhaps, I went to the distributor directly to RMA them.


Just the PSU, not my PC, I turned off my PSU (like unplugging the power cord) for a few minutes then turn my PSU on (plugging the power cord), and the noise will be gone, but the noise will come back if I press my PC's power button, either my PC will turn on or not


Yes, it will always boot to the windows and I can do 24/7 without getting BSOD, crash, etc. The problem if I ever turn my PC off, 80% of the time, I can't turn on my PC back.

That would depend on the rest of your syste. Always ad at least 25% over PSU's rated power as it is just "Maximum Emergency power" at rated wattage.

Not sure what you mean by that. At over 25% past the rated power a good PSU will have shut off, or a bad one will burn or have unstable voltage outputs.

I forgot to mention, for some reason I can turn on my PC by flipping PSU's power switch off, on, off, on quickly after I pressed my PC's power switch.

This is my system's specification :
i5 6600k
MSI Z170A Krait Gaming
Deepcool Maelstrom 240T
Seagate 3TB 7200 RPM
3x Alseye CL-120-B
Currently no dGPU, plan to get it later.

Yeah that will happen. When you flip it off then on quickly, sometimes it'll restart then.

Do you have another PSU to test? Perhaps it's the motherboard or a problem with the power switch itself. Try removing the power switch and shorting the power switch pins on the motherboard with a screwdriver to turn it on.

Unfortunately no, but during my 2nd RMA, they ran out of stock and lend me xigmatek 700W passive PFC PSU. It work great and there are no problem.


I have tried that, doesn't work.

So wait what happened to the Xigmatek unit them? That one works perfectly fine 100% of the time? Do you still have the Xigmatek?

It sounds to me like this company keeps resending you the same faulty PSU every time you RMA. If you want to be sure of that, make a tiny little scratch or indication mark to yourself, and you'll know when you get the same one back.

Yes, works 100% of the time and there is no problem as well.

No, they only lend me that when they are out of my PSU's model.


I will try that.

Update, somehow I found out that Muscle Power Thor 760 is a Seasonic X760. After reading from other forums it seems my local distributor (named DPJ) differentiate Muscle Power and Seasonic. Seasonic one is a brand new in retail box and Muscle Power is a PSU that have been for 1-2 years in the warehouse (CMIIW). What do you guys think? Will an old stock product that have been in the warehouse for 1-2 years perform that bad until I couldn't turn on my PC?

This a image about that

Okay, like you said, how do I put some marks on the PSU? Also, I used an AVR for my entire home, it's brand is Yamakawa and it's model is YK 5000 N. Will an AVR make an APFC PSU broke? (My local distributor said not to use an AVR) Is there any incompatibility in my PC? (Just to clarify)
