powercfg -h off
TSMikeW said: The power supply issue is certainly unusual. The EVGA Supernova's are generally very good units, and it's a single rail 12V power supply. We'd have to assume it's just defective.Regarding the powering off issue, this is a hibernate issue based on the sound of it. Remember, with Windows 10 shutdown is a deep sleep state really. Disable your hibernate or fast startup. Disabling hibernate disable fast startup, as that's the feature it's using. See if this eliminates the issue for you. You can do so via Power Options or via elevated command line.powercfg -h off
