Randomly, doesn't seem to matter what i'm doing (mostly during games but that is really the only thing I use the pc for), My computer will turn off and an american megatrends screen shows up saying I have been protected from a power surge and that this may be caused by an unstable power supply.
This has only been occuring after I installed my second graphics card(or upgrading to windows 10), I know I have more than enough wattage for my system so Im confused as to what is occurring.
Here is the voltages after running fire strike and unigine heaven https://i.imgur.com/gbEEuBc.png , they seem to be fine.
ASUS Maximus VII Ranger Motherboard @ lastest bios according to this https://www.asus.com/au/Motherboards/MAXIMUS_VII_RANGER/HelpDesk_Download/
Microsoft Windows 10 64bit
Intel Core i7 4790K @ stock speeds
Kingston Hyper X Fury 4x4gb 16gb RAM
MSI GeForce GTX 970 Gaming 4GB SLI (One is revision 1.1 and other is 1.3)Non over clocked.
Corsair Hydro Series H105 Liquid CPU Cooler
Samsung 840 EVO Series 250GB SSD
Seagate Barracuda 1TB ST1000DM003
Toshiba DT01ACA200 2TB 7200RPM
And the offending power supply EVGA SuperNOVA 750W G2 Gold Power Supply
I don't have another power supply to check this against is there anyway to find out what the problem is or should I just turn off Anti-Surge in the bios?
