Okay so I bought an evga gtx 660ti sc. I had to send it in for an rma bout a month back. Recieved a new one from evga. Sent it in for another rma this week. What would be my problem? Motherboard? Memory? PSU? The gpu crashes at simple games that don't require much.
I bought my psu open box. It is an Corsair ax 850. How would I test it if its broken?
Tried upgrading drivers to latest one, downgrading etc. Definitely not drivers.
It could be a faulty batch of cards on EVGA's side. Happened to me with Gigabyte once... You could just wait about a month and then order a new card so that it's from another shipment. I don't see anything wrong with your rig, it should be able to power the GPU without any problems.
