AX850 problem

[Contortion]

I've recently (a week ago) purchased an AX850 for my new build. However, I whenever I turn the computer, it starts to spin and then it stops suddenly and it makes a really bad like grinding. It also doesn't spin when I use my computer. I know that it doesn't spin up if it's lower than like 10% load, but i'm loading my graphics card with Crysis 2 in DX11 Ultra Settings and with 3D activated. Afterburner is registering 85-90% load most of the time, but the fan still doesn't spin up. But after about 15 minutes of playing, it shuts down. It tries restarting but it won't unless you physically intervene, turn it off and then turn it on again and it'll load. It's the PSU fan that's not spinning up by the way.

I've also had the same problem when just using the desktop.

So is this just like burn-in time or is it a faulty power supply?

Specs:

Core i7 2600K (stock, haven't had time to overclock)

Z68A-UD3H-B3

G.Skill Ripjaws 8GB 2133 MHz RAM

Gainward GTX580 Phantom

Noctua NH-D14

NZXT Phantom

AX850

Corsair Force 3 120GB SSD connected to SATA III

1TB Seagate Barracuda SATA2

SATA DVDRW Drive

Windows 7 Ultimate

Samsung 27" 3D Monitor.

Ax850 is normally running quiet,even at high load,and with your setup,only 65% max load on this psu.Grinding noise is most likely a faulty fan.

Rma time i think

I don't think RMA is necessary, try going back to the store ( if possible ) and get an exchange.
