My father bought a new rig last week.
It's a HP Envy Phoenix with:
- GEFORCE GTX 780 3072MB (Think it had GTX 760 stock)
- Intel i7 4770 3.4 GHz
- 16GB of RAM
When under heavy load the computer restarts itself. I've tested it with Battlefield 3, Tera Online and FurMark 1.13.0. I've ran FurMark on a low resolution and it instantly restarted.
The GPU uses latest available drivers.
The PSU is a stock one from HP. Model: DPS-600WB A
GPU says it requires a 600W power supply minimum. Could it be that the PSU is too weak or are there any other possibilities?
