If it only happened one time, and didn't happen again (yet), I wouldn't immediately buy another PSU. You could potentially have video card driver issues or even windows driver issues. Try downloading DDU (Display Driver Uninstaller) and uninstall all video card drivers and reinstall. Do some tests on the PSU, like stress tests on the GPU and CPU or change settings in games while monitoring CPU and GPU power usage. Do you hear any noises coming from your PC, particularly near your PSU? Have you dusted your case out, and dusted out the fan of your PSU?
