I have been trying to diagnose this issue for a week or so now. I am fairly certain its the PSU, though it is a brand new unit so I didn't want to blame it immediately.
The PSU is 875w with one 7990 at stock. Everything works just fine when its not under heavy load. However when I say execute a bf of 8 chars, the operation lasts between 17-20 mins and then my system reboots.
I have watched all the sensors, the GPU is not overheating (around 80 C) and all my other sensors are well below temp ranges (water cooled CPU) So there is no temperature issue.
I've tested the fans on the cards and they respond properly and the fans in the case are fine.
I believe 875w is fine for a single 7990, but I was wondering if anyone else has run into this. I checked the forums for previous posts and found nothing directly relating to this (the googles too)
Again, running masks and rules and normal operations I have no issues, just under a heavy load it simply reboots consistently.
Any other tips on troubleshooting is greatly appreciated.
Thanks in Advance,
Eric
