Just got this PC a month ago. Noticed a buzzing noise on occasion. Could be a rattle. Seem like it happens when it is under load while gaming. Think it might be coming from the power supply. Have 850 watt psu. Is this normal? First time owning a gaming PC. Love this thing.
It does not sound normal, please send me your Service Tag in a PM so we can look into this and get back to you.

Sounds like it might be this problem:
However, be sure it's not just the side panel vibrating or something (which is much easier to fix ). I suggest you power-down, remove side-panel, and run it like that until you can isolate the noise.
