Weird noise from PSU ?
Weird noise from PSU ?
Hello everyone.
I'm using an MSI MAG A750AG PSU and it was making a strange noise yesterday. I looked at all the fans, but the sound came from the PSU fan—like a cable is hitting it or something is loose. I don’t think it’s a cable, but I’m just describing what I heard. After turning off my PC for the night, the noise stopped. I sent an email to MSI about a warranty since it’s only two months old, but they haven’t replied yet. My question is, should I keep using my PC or replace the PSU with an older one, like an Aerocool 650 watt? My PC has a Ryzen 5 9600X and an RTX 5060 Ti. I’m not sure if that power will be enough.
since yesterday my computer was making a really weird noise I checked all fans and was coming from my PSU fan.
Perhaps include a video with audio of what you're experiencing. Host your clip on a site akin to Imgur and then pass on a link for us to see. You can use a sheet of A4 paper, rolled up into a cylinder, with one end held to your ear while the other end is used to probe for the source of the noise.
My question is should I use my pc or should I replace it with an old one I got. It’s from aerocool 650 watt and my pc specs are R5 9600x and rtx 5060ti. From watt should be enough power to run my pc without any issue
Wattage isn't the only thing you look at when working with a PSU. We advise working with reliably built units. That being said, Aerocool is the brand of the PSU while 650W is the advertised wattage for the unit, what is the model of the PSU in question?

It’s from aerocool 650 watt
Due to the limited info we have, at the time of writing, by any chance did you reuse any of the prior PSU with the new PSU?
However I emailed MSI about warranty since is 2 months old and they didn’t reply to me so far
Make sure you've informed your seller as well, having them both in the same email helps with your case if this indeed worthy of an RMA.
my pc specs are R5 9600x and rtx 5060ti

For the sake of relevance, that PSU is Tier-A, per this list;

This morning it doesn’t produce any sound at all, but if it does I’ll create a short video and update this post. Don’t worry, I won’t need any A4 paper sheet to hear it—it was so loud I couldn’t sleep even yesterday because of the noise. A vacuum produces less noise xD.
I’m sorry I didn’t write everything down. It’s an Aerocool White 600w, similar to Tier C, and it kept my old PC running for about three years, which was a lucky thing.
I’m not sure if I’ll get this right, but I haven’t reused anything. Everything is clean—no mixing cables or anything else. If I do it correctly, I hope it’s correct.
CPU: R5 9600x

I’ll wait a bit to see what MSI says. The seller is on Amazon, so I don’t know if I can get any assistance from there.
I am sorry i didnt write the whole thing down. its Aerocool White 600w its like Tier C i know but this kept my old pc running for like 3 years i may was lucky,
I don't know where you're seeing that PSU as Tier-C. I know that they're garbage units and on these lists;

it's listed as Tier-E. I hope you didn't use said horrible unit on your AM5 build. If you did, I'd keep an eye and ear out on any further anomalies.
i didnt reuse anything all setup is clean with no mixing cables
That's great to hear!

on this list is a PSU Tier B
How about this? Take a picture of your PSU's stickered info, host the image on a site akin to Imgur, then pass on the URL onto this thread for us to see. It's so we don't misinterpret the PSU you're working with.
I haven't used it yet; I have it as a backup PSU in case I need to run for a few days. Am I okay with the Watt limits?
I'm really grateful for your help, but today it didn't make any sound at all—I don't want to jinx it. To share this picture, I have to remove it completely because the label is on the downside and it's not making any noise. However, in the link below is the model I have; I hope it helps.

Hi mte you told me to keep you update if the noise will come. Well today came back not that loud but you can tell thats something is going on there. I couldnt upload the video on Imgur but i did in youtube here is the link from the noise

i cant order a new one to replace and support team from msi didnt reply yet my only option is to use this aerocool PSU that i got.
You have two alternatives:
1) Keep using the MSI MAG A750GL without swapping, as the noise isn’t excessive and replacement seems reasonable.
2) Disconnect the system completely until the MSI PSU is replaced.
2 days ago was quite noisy, I couldn't sleep yesterday but it was working fine; today it's doing better but not as loud. I've been consistent with MSI and haven't received any replies yet after 48 hours—they should respond soon. It's tough to use the computer, so I'm keeping it at minimal use and avoiding heavy tasks. I won't use the Aerocool because I don't want to risk damaging my RAM, which can be very costly since new ones are four times more expensive than what I bought. I plan to visit my local hardware store tomorrow to see if they have any PSU from brands like Corsair or others I trust.
The issue with the Aerocool lies in its limited power output of 600W, combined with its low build quality and likely age. These aspects increase the risk when using it alongside a powerful graphics card, even briefly. It's unlikely that a brand-new, high-performance 600W power supply can handle the sudden current spikes from your GPU. Nvidia graphics cards may encounter difficulties with insufficient power sources.
Removing the 5060 temporarily would ease the strain on the PSU, allowing continued operation if your power unit is weak. However, purchasing a new PSU requires caution—avoiding low-quality models could lead to further damage to your system.
In theory, the built-in protection features in any ATX power supply should safeguard your computer if the unit fails completely. In reality, a budget PSU with poorly designed safety circuits might cause extensive harm to your motherboard, CPU, RAM, GPU, and even the SSD under extreme conditions.
Therefore, we suggest opting for a premium Tier-A power supply. Although more expensive—often three to four times more costly than a basic Tier-F model—these offer a longer warranty (typically 10 years) and more stable power delivery.
The noise you hear from your MSI PSU could stem from fan blades contacting a thin plastic shield, which sometimes guides airflow to critical components needing better cooling. The tips may occasionally tap against the plastic, especially if the shield has shifted inside. Avoid probing further—such conditions can lead to hazardous voltages.
Another possibility is interference from a nearby wire, which is not ideal. Prolonged operation could cause wear on fan blades, leading to insulation damage and potential short circuits over time. Handle with care.
The only situations where I leave computers running overnight are during backups or long video editing sessions. If the system keeps you awake, it's best to shut it down.
For GPUs from Nvidia, we advise a current Tier-A ATX 3.1 compliant power supply with ample extra capacity. Avoid anything below 750W for an RTX5060; an 850W or higher unit would be preferable. A 650W model might suffice, but the risk isn't worth it unless you can easily replace it.
My outdated 750W Corsair TX850M ATX 2.1-compliant PSU from 2021 couldn’t consistently power my RTX 3060. On rare occasions, the system would crash and restart when both the 3060 and 7950X ran at full capacity.
I resolved the issue by switching to a modern ATX 3.1 MSI A1000G PSU. The manufacturer sets the protection threshold at 200%, but the older TX850M likely tripped earlier—around 120%—which could explain the abrupt shutdowns.
You might face delays in getting a response from MSI or receiving a replacement before the new year if you wait too long.
Thank you for your message. I discovered one PSU in good condition at price tier B+ here: amazon.de/Thermaltake-Toughpower-750W-Modular-80Plus/dp/B0DNZFXMTG/ref=asc_df_B0DNZFXMTG?mcid=910f823329653c5a95e50269f4dbf1bc. It seems to be the only option available, and I can expect it soon, possibly on Saturday. The Amazon return policy is about a month after purchase, but I understand it might take time to get a response from MSI. I see this as a temporary solution until I receive a reply. You mentioned it could be a plastic cover covering the fans; I won’t touch it or open it, as high voltage must be avoided. Recently, I noticed a plastic sheet during inspection after removing it completely. I’ll refrain from doing anything—warranty remains active even if I unscrew something, which would cost $110. I’ll wait and won’t use an aerocool; I’ll discard it instead. If you find the Thermaltake as a backup, I’ll keep it after purchasing it.
