That is one of three issues:

1) Thermal shutdown, all Intel CPU's do this, which means you need to replace/clean the cooler/fan on the CPU. (GPU's thermal shutdown is the dreaded "the video driver has crashed" type of message.)

2) PSU is under-sized for the GPU being used, or the power draw through the GPU power cable is too much and is tripping the breaker in the PSU. You need a 500watt PSU or better for that GPU to cover the maximum power draw (145 watts) for that GPU. The CPU you have selected is an 84 watt TDP, and the haswell series is slightly problematic when it comes to thermal cooling, as the stock thermal paste is basically rubbish.

3) If connected to a UPS, Most computer GPU's are too powerful for anything less than a $500 UPS, and don't have the proper sine-wave AC, so this results in a loss in efficiency for the PSU.
