This is my first computer build, which I based heavily off the suggestions from Dassault's official forums on a Solidworks rig for work. Twice in one month, my power supply has blown out. I am connected through a UPS into the wall socket. The first time my PSU blew out, my coworkers mentioned a "pop" sound from my case, with the ceiling lights flickering (sounds like a surge). Our facilities are quite poor, so I am not surprised we have surges, which is why we have UPS's at each computer. The PSU failed the paperclip test and Corsair replaced it one month ago. I swapped out the UPS with a different one (thinking it may not be protecting properly), and one month later, my computer would not turn on, and the new PSU failed the paperclip test this morning. Based on my build, a 650W PSU should be sufficient (I used a PSU calculator and even added a couple hundred extra watts to be safe). This computer is used to run CFD (computational fluid dynamics) simulations for days on end (very high CPU use for up to a week straight). I use an aftermarket cooler on my CPU to keep things nice and chilly (30-40deg C). In general, the computer performs just fine despite the heavy use.
I am at a complete loss of why this is happening. The UPS should be preventing a surge from injuring my equipment (every other device plugged into the UPS has been totally fine after a surge, and the UPS itself reacts and resets itself after a loss of power from the wall.) Could this be related in any way to the build itself? I followed a Dassault professional's advice very closely on components for my build. Perhaps there is an issue with running at high CPU load for days on end? A blown out PSU seems extreme. Again, I want to stress that our facilities are quite poor, and power outages/surges are not uncommon, hence the UPS's at each desk.
I would greatly appreciate any advice on what is going on here, as the computer is used heavily amongst the small company I work at. Thank you!
