Min dator låter underbart!

Hej

Är det PSU som låter så? När man starter ett spel då börjar datorn låta, det kan var lite störande ibland om man inte har hörlurar.

Det är ingen fläkt. Jag är helt hundra på att det är från PSU. När datorn börjat äta för mycket ström så kommer ljudet.
Annars kan det komma från grafikkortet.

Det är inget fläkt ljud.....

Jag hitta det.

If you believe that your PSU is louder than it should be there are a few things you should check before assuming that the PSU is faulty. First, you should be aware of what can cause the noise that you are hearing. If you are hearing a buzz or electrical type sound, then it’s likely due to a capacitor somewhere in your system that is vibrating at a frequency which is clashing with the rest of the components in the system. Usually this capacitor is either on the PSU, motherboard, or graphics card and you should be able to try a few things to narrow down the issue.

We have seen that the CPU power saving features in the BIOS can cause the PSU to emit the noise. Try disabling these features to see if there is any improvement. ERP, C1E and EIST (Enhanced Intel Speedstep Technology) are few examples of power saving settings, but your motherboard manufacturer should be able to tell you specifically which features your board supports.

We have also seen that some graphics card drivers can contribute to the sound as well. If the problems seem to get worse when loading a 3D application, try booting your system up into safe mode to see if you can still hear the sound. If the sound goes away, then your problem may be software related. We have found that enabling “vsync” in your graphics drivers options can eliminate the sound.

If the previous steps have not eliminated the sound, then you may want to test the PSU in a different system just to be sure that the sound follows the PSU. If it looks like there is a good chance that the PSU could be causing the problem, then please request an RMA through our Support Ticket System and we will be happy to replace it.
