Rmx 550w noise

[doganos]

Hello i recently bought the RMX 550w and it is making a noise. I recorded a video so you can here the noise.

The noise in the video is with the cpu 100% load in prime95, it does the same noise when the system is idle but you can't even hear it.

Also the fan never spins (i know it has the zero RPM mode) but i tried prime95 and a gpu stress test at same time for 20 minutes again no spin.

System: ryzen 1700x, gtx 750ti, 16gb ram

So i have to RMA this unit, what do you think?


Thanks in advise.

the fan should spin, with the computer off can you manually spin the fan?
the fan issue would be enough for me to return it, the noise puts it over the top. return it

Possibly a capacitor vibrating.

I would RMA if your sure it's coming from the PSU and the fan doesn't function.

It does take a decent load for the fan to kick in.

Nice review that included load testing for the passive mode.

the fan spins when i turn on the PC and then stops when im logged in to windows, also i can manually spin then fan yes.
Well i guess i have to RMA it then if it's not spinning under full load and with the noise on top as you said

Thanks for the info

I see. yep it spins only when i power on the pc and stops when i log in to windows as i mentioned above in my reply.
The thing is im in the middle of a job and i have to deliver some render in ten days so if i go for RMA right now is a disaster.
On the other hand its not wise to keep working with that PSU even if its for ten days

You wrote "The noise in the video is with the cpu 100% load in prime95, it does the same noise when the system is idle but you can't even hear it." I hear what sounds like fan noise; are you absolutelyb sure it isn't the CPU fan? Your PSU fan doesn't spin and it doesn't have to; therefore the fan noise can't be from the PSU.

The fan should not spin with that computer of yours, even full load is going to be quite under 200W. I repeat, the fan should not spin.

In some scenarios it may take over 300w.

So anyway, let’s get to the RM550x. We can see it was running fanless until test four, or more accurately, it started spinning somewhere around 320 W.

Not with that hardware while running P95 and no GPU stress test.

I wasn't comparing them...Just pointing to the article.

I had an RMx 650 - started making popping noises when I was turning power on at the wall. They're garbage. Return it and get another brand.

The sound is from the PSU im sure. i cheked carefully all the components and also it wasnt there with the previous PSU.
Yes i know that the fan spins when it hits 60% load and maybe 1700x and gtx750ti cant reach that limit even in full load thats why maybe the fan never spins

well i bought it after reading some good reviews about it, ill go to the local store tomorrow and see if i can get a replacement or another PSU

The RMx is a very high quality power supply.

The noise sounds like electronics noise to me upon listening to it. Electronics noise isn't harmful but can be annoying and can be a good reason to return it.

The fan is not going to spin with that little load you have.

Correct. It's just an X cap vibrating. Totally harmless.

You're an idiot. You're cutting off AC power to the PSU from an outside source then throwing a bunch at it when you turn the power back on at the wall causing enough of an inrush to cause the circuit to arc. Do you also put your foot all the way down on the gas when you start your car then complain that it revs too high? Jesus F. Christ.

So you're trying to tell me that a power supply making a loud popping noise every time I turn my PC on is completely normal and not an issue? I think many people would disagree. When I put my foot all the way down on the accelerator I expect the engine to hit redline. Unfortunately a wall switch is on/off and there is no way around that - therefore it's a problem.

the problem is that you keep powering down and powering up the unit via the wall switch. plug it in and leave it plugged in.

like a tungsten bulb turning it on, powering it on, the inrush current does the damage. take an old style bulb and flip it on and off and on and off, it will burn out quickly. the inrush current every on cycle will vaporize the tungsten filament until it breaks and burns out. Or the same bulb switched on and left on can burn for 117 years.

the power supply is not designed for repeated complete power loss. the repeated on cycles are the problem. plug it in and leave it alone. use the PC to shut down the unit, use the PC to turn on the unit and it will last beyond the decade corsair warrants them for

For me when it comes to power supplies, if my computer (which is attached to the power supply) is running perfectly fine, I don't worry about the power supply. If there was something wrong with the power supply, I would assume that it would interfere with the proper functioning of the computer, as the sole purpose of the power supply is to allow the computer to function. Large inrush current can make noises.

I think the fear of many people, which they may not fully express, is that noises they hear are more like ticking time-bombs; they are not causing harm at the present moment, but they fear that one day Boom! - that noise that's been going on for months just caused a catastrophic disaster inside the power supply, rather than having ever showed any signs of possible failure beforehand (like computer freezes or shutdowns).

What is more like reality is that a good power supply like the Corsair RMx is well-protected, and usually if something is going toward gradual failure you'll get some signs, such as your computer having issues, rather than some unexpected decimation occurring.

A long time ago I had an EVGA 500W power supply. I heard a little high pitch noise in the back. I thought "crap, the power supply must be dying, better get a new one." Years later I realize I was incorrect in that assumption and the noise was just a harmless noise. My computer never had any problems - but I replaced the PSU because I was afraid one day that little noise would turn into a big Boom! But that's very not likely to happen, and if a noise is simply coil whine it's no harm. It's still running in a computer I made out of spare parts for my brother.

Electronics can be noisy. Go around big huge electronics in industrial stuff and you won't find silence. If the PSU noise is annoying you, return it for that, but do understand that noise itself is not an indication of the power supply being or going bad.
