Arlineas Posted December 2, 2020 Share Posted December 2, 2020 (edited) Hy Guys, I just bought a new RM750x series PSU from Corsair. I noticed a little strange noise which appears randomly even when PC shut down (Switch power button ON) It only last 3sec and stop Do I have to worried about ? Is it normal ?

Corsair Employee jonnyguru Posted December 2, 2020 Corsair Employee Share Posted December 2, 2020 I didn't hear a pop. I justt heard high frequency magnetic noise. Is that what you're talking about? Link to comment Share on other sites More sharing options...

Arlineas Posted December 3, 2020 Author Share Posted December 3, 2020 Ok thanks. I didn't notice with my previous PSU so I asked. Its a little bit disturbing when working on my desk but I will switch off my PSU when I do not use my computer ^^ Link to comment Share on other sites More sharing options...

If it's so loud that you can hear it without having your ear right up against the PSU, then you should consider exchanging it. Unfortunately, with increased efficiency requirements and increased safety requirements, it's harder and harder to get a PSU to be completely quiet across a complete range of loads.

Arlineas Posted December 3, 2020 Author Share Posted December 3, 2020 Why not ? Is there a problem shunting off PSU every day ? It's not so loud, I just notice sometimes Link to comment Share on other sites More sharing options...
LeDoyen Posted December 3, 2020 Share Posted December 3, 2020 well you shock the protection circuitry each time you switch it on. It will last some time before you start to see sparks when doing so, then you may end up killing the PSU in short notice, waaaaay before its warranty is over. In general, electronics don't like being powercycled. that's their kryptonite Link to comment Share on other sites More sharing options...
Vegan Posted December 4, 2020 Share Posted December 4, 2020 Use the Windows standby feature which is far more effective besides the monitor, the standby wakes the box far faster Link to comment Share on other sites More sharing options...
