Question about PSU screeching noise during startup
Question about PSU screeching noise during startup
I have a pretty precise issue with my PSU, a Corsair RM750e. It's usually quiet and hasn't caused any problems at all. I'm really satisfied except for this small problem when loading "Dying Light." During the loading process, especially in that game, my PSU started screaming—just for a short time. It depends on whether I let it load slowly or speed it up quickly. In this game it happened, but not in others, even more demanding ones. Maybe the real cause is that my CPU and GPU usage fluctuates a lot when loading. I already had problems with this PSU or its version—it would crack when switching tabs from a game. I replaced it with Corsair right away and it worked fine until now. The PSU and the whole PC are about 2.5 months old. Any suggestions?
Welcome to the forums, newcomer!

The RMe units aren't exactly a good unit, Tier - B and there have been reports of the unit exhibiting the same issue across all versions of the RMe(across the 3 years since it was released).
You're certain the noise is coming from the PSU, specifically? Use a sheet of A4 paper rolled into a cylinder and hold it to your ear. Use the other end to probe for the source of the noise. Generally the noise will come from any delivery area in your system which can be the VRM area of the motherboard and/or the GPU. I've had coil whine off of a Sapphire Nitro+ RX 6700 XT which only produced coil whine when you fired up Call of Duty online(or Warzone). It was reproduceable on that title while everything else didn't produce the same noise, not even rendering complex scenes in D5(similar to V-ray).
Try and relocate to another wall outlet and see if the issue persists.
You've posted this thread in the overclocking section, what are you overclocking(or have overclocked) exactly?
So I found out the loading screen was uncapped and J was seeing around 4000fps, which wasn’t an issue now. But I wanted to clarify what you meant by saying the RMe isn’t a good unit. If you could explain more to SM, that would be really helpful.
From all I've observed, the RMe performs well overall, though it experienced electronic noise issues (possibly limited to the initial launch). It tends to be noisier than similar models in its price range. The problem might stem from higher power usage compared to others, which could explain the noise. You could try reducing the frame rate in that specific game and check if it affects the issue. If it does, it's likely the cause.
I understand the noise issue with the first one I bought—it was really loud, and after getting a replacement from Corsair, they gave me a new one without even asking about the old one. Now I barely hear anything at all. The only thing that bothers me is the hot plastic smell on the back side of it; it’s not burning, just hot. It’s my first desktop PC, so I’m not very familiar with it, but it only smells when I’m close to the power supply or after the computer has been under stress for a day. It can make the room smell a bit, like the smell of a hot car in summer.
When browsing the web, especially on Reddit, many users have had to send return requests for their devices due to coil whine or instability problems. Some discussions on this forum suggest the problem was linked to the RMe unit.

The device appears as Tier - B on that page but lists as Tier - A.

On this link, the situation is explained further.
EVGA had a history of producing faulty units within their top-tier PSUs, suggesting the RMe issue might stem from a manufacturing flaw, possibly tied to a particular production run. If Corsair didn’t require returns for defective items, it implies they’re aware and aren’t conducting internal testing.
To put it differently, after Amazon’s New World launched, GPU and PSU performance issues like coil whine became more common, prompting me to stay alert even if frame rates are limited.
From what I understand, Corsair mentioned that some units had problems and were being sent out for about a month. I received one of them, but it was definitely loud. They provided me with another unit from a different batch, which made things much easier. I’m glad it worked out so smoothly. Thanks for your assistance. I just want to know if the heat or the smell might be causing any issues.
You're welcome, but I don't experience this regularly. It doesn't happen often, and when it does, it's usually not noticeable. Thanks again!
