Grinding noise inside NEW PSU please help

Help i have a grinding noise inside my new 550w megapower aywun (PSU). When i move my tower from side to side the griding stops but when i move it back so it's flat verticle on the ground it makes the noise again. I've had this new computer for 2 weeks and it's custom built. The computer is practically brand new. could it be the fan? idk. It shouldn't need to be cleaned out this early should it? 2 weeks into use and already needs to be cleaned? that's a little insane.

The PSUs fan does still work when i move it from side to side. i currently have a peice of paper under one side to stop the noise. The fan works so it won't burn out...

Are you sure its a grinding sound rather than a vibration sound? you often can get vibrations sounds comming from the case when you have fans running. Pop the case open and carefully investigate where the sound is comming from, avoid trying to prod anything and do not put your hand inside the case.

just try to localise the sound and see if the fan is grinding against the grill, or if it is in fact a vibration caused by the fan.

I never heard of that brand PSU. Where in the world do you live? Below is a link to the specs of that PSU. It has 2-+12V rails, neither is sufficient IMO. That said, the problem sounds like you have a flimsy case and it is twisting. If the covers are not attached with screws then you should install them.

Custom built doesn't necessarily equate to quality. From the little we know about your new PC I would have to speculate that you didn't get quality hardware.

If it was built from a reputable shop then you have a warranty and you should address the issue with them

You have to be a little bit crazy to keep you from going insane.

I think it's more a vibration but it's like... it's hitting something... it's not a grind i guess but that's the closest thing i could think of that is close enough to it.

Its not recommened you open a PSU unless you are qualified. The capacitors hold a hell of a lot of charge and it could be dangerous.

take out the PSU and while it is OFF and unplugged try to turn the fan with a pencil. see if it is in fact touching something, if it is a loose fan well then you have two options, either tighten it (yourself if you want to or take it to a shop) or buy a new PSU.

if it is not the fan, then as OtheHill suggested abpve, it could be a twisting of the case/flimsy case etc which to me sounds like to be a higher possibility.
