New pc with loud psu at idle [Please Help!]

[Predz]

Hey everyone!

 

Yesterday i bought a prebuilt pc which came with a Cooler Master MasterWatt Lite 700W Psu ( I know, not the best psu out there ) 

 

From the first boot the noise was noticeable and I thought it was the psu fan, but on closer expection it is the psu itself that’s making the noise.

 

While searching on the web for a possible solution, the pc went into sleep mode and the psu quiet down as if it powered down, but I could still feel cold air comming from the psu fan. The noise was gone even when I got out of sleep mode and openen some files and browser pages just to see if it would kickstart the psu noises again, and there weren’t any. When I did a restart the noises came back.

 

Did my brand new pc come with a faulty psu or is it somehow stuck at full power whenever I boot?

 

Any help would be greatly appreciated!

First of, the CPU is an i7 6700K or you're mixing it up with i5 7600K.

 

That sounds really bad.  I'd replace it.

probrably coil whine, it can sound like buzzing, or in my expirience even like ticking

This was my case:

Only solution - warranty repair

Another reason to build a system on your own and choose all components. Since you bought it yesterday return it, would be my advice.

Agree with this one, return if possible.

 

Who pairs an i5 and a 1060 with a 700 watt PSU  not to mention they've paired a K cpu with a B250 board...

Replace the PSU with one that is truly what you want, if possible.

FYI:  PSU fan is an intake.  There should be air coming from it.

 

Also, 700W is overkill.  Not that that fact has anything to do with your noise, but for the cost of that 700W PSU, they could have used a much higher quality 500~550W PSU.
