Is the squeak of the power supply a sign of problems at the level of microcircuitry, or can you still live?

Question

Iron

Hello.
The other day I changed GTX1066 to GTX1080. CPU - R5 3600 with small add-ons in the BIOS, no overclocking. A lot of peripherals are connected - 7 coolers 120x120 and 4 drives.
The last old element remained in the assembly - the HIPRO HPC500W-Active budget power supply. At 1066, its features did not yet painfully make themselves felt, but now the PSU squeaks under load. Loud and disgusting. In the beta test of the new CoD: MW, for example, the squeak became stronger precisely on the loading screens.
Considering that at this level I have a minimum of knowledge, I ask for advice. Is it scary? What threatens? Can my assembly crack under load, or can I just be patient and not worry?
I plan to change the PSU no earlier than November, I aim for 650W Gold to be sure.

Answer 1

About "shvarknut" under load - almost any PSU can. It is not always associated with whistling. Well already written by Victor .
I will add. I repair electronics, and PSUs are often. Often extraneous sounds and unstable operation (especially under load) occur due to the increased ESR of capacitors in front of the gates of power transistors (usually two of these, 1-10uF 50V). This is easily diagnosed and treated by replacing tired capacitors (they almost never swell, they cannot be distinguished by sight, only with a device).
Another reason is the already mentioned chokes and transformers. They can whistle due to the presence of harmonics or parasitic frequencies (which should not be). It is detected by pressing a pencil while working on a suspected part.
There is another factor that increases the ability to "slam" - the circuitry itself or the specific elements used. For example, blocks repeatedly came across where exactly power transistors of a certain manufacturer exploded, even when they were obviously with a margin. Well, they have such a "tendency". Also, specifically in the HIPRO 500 (I won’t tell you exactly the model, I don’t remember) I came across banging power ones along with PWM and secondary transistors, and the PWM was some kind of specific or custom - I couldn’t find the exact one even on Ali, and I couldn’t find an adequate analogue ( Something always went wrong.)

Answer 2

Throttles whistle at the BP. How long only the throttle itself will work knows)

Answer 3

Perhaps a detailed answer is needed here.
1. About the load and power. You yourself mention that a lot of things are connected. Therefore, it makes sense to estimate on the calculator the total power and the sum of the currents through all the PSU channels (3.3, 5 and 12 volts) from this iron of yours, and compare with what is indicated on the PSU sticker. At the same time, it must be borne in mind that a power supply unit with a marked power of 500 watts in reality will not give so much during long-term operation, but will give one and a half to two times less. 500 watts is the so-called. "marketing" power, a larger figure to attract the attention of buyers. The same applies to the currents printed on the sticker. Of course, the BP can give out as much as it is written, but only for a very short time. Or maybe not give out if there is overcurrent protection and it will work. So yes, 650, and even better 800.
2. About the squeak. The sound is a consequence of magnetostrictive pulsations of the magnetic circuits of the ferrite parts of the PSU. Occurs in a strong magnetic field, is not dangerous in itself, but can serve as a signal that the limit load is approaching. Just in case, it makes sense to inspect the inside of the PSU in working condition and touch those parts that are not under high voltage. If the sound changes when touched (or even pressed), take a closer look - cracks or loosening of fasteners may be found.

Answer 4

Here is an interesting topic.
The load became larger - the conversion frequency became lower and fell into the audio range. Who knows how much the PSU will still work, if you have knowledge in electrical engineering - you can try to cope with it yourself or change the PSU for a better one.

Answer 5

Squeaking for electrical components is a normal phenomenon, many power supplies, video cards and processors squeak during operation, this is normal and usually this sound is hidden behind the sound of coolers and hdd. in your case, the squeak could increase due to an increase in the load on the components of the power supply, the video itself can also squeak.
As for how long your assembly will work, no one will say, but in the best case it will be a finger in the sky.
