Greengolfer is right. Software just can’t be responsible for “blowing up” PSUs. While X-Plane is surely capable of pushing both the CPU and GPU to their maximum power consumption, a 700W PSU is plenty adequate.
In the early days of XP11, I had a cheap 400W PSU. Whenever the GPU power loading went beyond 80%, it would trip the PSU. The PSU abruptly shut the system down, but it could always be powered back up.
When power supplies keep getting “blown up”, I tend to suspect shorts—on, under and around the motherboard and case.
