ashank Posted April 28, 2014 Share Posted April 28, 2014 Hi, My recently 1 week old purchased Corsair CS750M PSU from Canada Computers seems to be making some noise. I have the NZXT Phatom 530 full power case, with slot for PSU at the bottom of the case. I placed the PSU with fan facing down towards the vent. However, I am finding that it is making a high pitched noise that is really disruptive. Should the fan be facing up towards the motherboard and GPU? Could it be a defective part? It is very audible. Even when i turn on my computer, I hear big shrieking noise for 3 seconds, and there after the sound dies out. Furthermore, when watching a movie, I can hear the buzzing noise coming from it as well. My specs are as follows- NZXT Phatom 530 case Intel I5 4670K 3.40GHZ Nvidia GTX760 CS750M PSU Gigabyte GA H87N with wifi 8 gb RAM 1 TB Seagate hard drive 120GB Kingston V300 SSD Link to comment Share on other sites More sharing options...
Corsair Employees jonnyguru Posted April 28, 2014 Corsair Employees Share Posted April 28, 2014 The orientation of the PSU should not matter. I would go back to Canada Computers and exchange the unit. The noise is not normal. Link to comment Share on other sites More sharing options...
