Help, brand new build, power supply is making a weird noise

[24nolf]

Just completed a brand new build 1o minutes ago.

Upon start up my power supply is making a fairly loud noise it sounds like the fan hitting something. Visually I cant see it happening, I restarted it a few times, nothing changes. The machine seems to be running fine and its currently installing windows.

The power supply is the PC power and cooling 750 W Silencer MK II.

Should I turn the machine off and return the power supply? Should I just let it run?


Other Components:
MOTHERBOARD Gigabyte p67A-UD4-B3
CPU INTEL 2500k
GPU MSI 560Ti
RAM 8GB Corsair Vengeance
CASE CM 690 II Advanced
HD Caviar Black 1TB

I'd really appreciate any help, and if I posted this in the wrong place please let me, I'm a newbie to the forums

Turn it off, and return the unit, dont take any chances with all your new shiny kit, as it might all end in tears, also buy a better quality unit like these

XFX P1-750B-NLG9 Black Edition 750W Modular Power Supply

Silverstone Tech. SST-ST75F-P Strider Plus 750W Modular Power Supply (PSU)

Corsair Enthusiast Series TX 750W V2 High Performance Power Supply

All good psu examples you linked Uther39, but a PC power and cooling 750 W Silencer MK II is a better unit.

Yes i no what your saying Davcon, but i had 2 PC power and cooling units and had to return them both, in the end i gave up and bought XFX units.
