Hi everyone, I just finished my first build last weekend. Components were:
I immediately had one big problem with the build: the computer would randomly reboot after 10-20 minutes of one particular game (Overwatch). It worked fine with everything else (including Witcher 3 on ultra settings), I monitored the GPU and CPU to make sure the system wasn't overheating (it wasn't), and it passed testing with Furmark, Prime95, and Memtest86. So, having eliminated other potential problems, I decided the problem might be the PSU and replaced my old one with the Corsair Vengeance 750M, which is a slight upgrade.
I tested Overwatch again while lowering the default settings (which I was using when it crashed before) from "ultra" to "high" and turning on VSync. No reboots, everything looked good in terms of temperature monitoring. I tested a little bit more by going back to the default settings. Again no rebooting, but I noticed something interesting: turning off VSync would cause the GPU to use about 40 more watts (up to 140) and raise the TDP from 40-50% to 80%, even though the load on the GPU remained stable at around 40%.
So, here is my question: should I be concerned that I'm pushing the PSU or GPU too hard by using the default settings, or does it look like the reboots were caused by a defective PSU? I'm happy to turn my settings down if they're overloading the PSU too much, since I don't want the reboot problem to reoccur, but I thought the PSU I was using had more than enough power to run the GPU even at its full power consumption. What do you guys think?
