Getting crashes

[WildMonkey]

I was wondering if I have enough juice on my Corsair HX520 to run my rig, cause it seems to be crashing during gaming. Rig is as follows:

i7 920 @ 4GHz, 1.275v
6 GB RAM, 1.6v
Gigabyte x58 mobo
XFX 4890, not OC
4 HDD
2 DVDrs
Sound card
wifi + bluetooth dongles
Corsair HX520

Edit: My bad 1.275v on the CPU, 1.6v RAM

2.75v on the CPU?

Aside from that voltage, the PS should run games ok. The the GPU or VRMs on the video card may be getting too hot.

You have enough Juice, but 2.75v (you sure?)
Ram can't be 2.6v (you sure?) Maybe 1.6?

Oh and BTW the crashes have been in the form of total system lockdown.

Have you checked to make sure your CPU overclock is stable?

The HX520 is enough for your system, and overloading it wouldn't cause the symptoms you're having. The issue is being caused by something else.

Yes Prime ran for ~10 hrs no errors.

Even though your video card is not OC'd, dial back the memory clock a little. See if that helps. I was getting similar problems with my old Diamond 4870 card, and I simply dialed back the GPU clocks (it was at stock settings), and that fixed it up. Sometimes stock GPU settings are too high - you might have gotten a mediocre 4890. Good luck.

Also, are you turning up your fan before you game? I manually turn my fan up to 40% before gaming with no issues. I turn it down to 20% after gaming.
