two suggestions:

1) try disabling the "PEG Link Mode" in the ASUS BIOS. This under-documented utility automatically overclocks your video card, which might be causing the crashes. Personally, I'd like to be in control of any video overclocking that is going on in my system.

2) If that doesn't work, swap the PSU. There may be nothing wrong with the PSU per say, but there have been MANY REPORTS of the Antec Neo Series not playing nicely with ASUS boards. Simply changing to a different brand may do the trick.
