A: Then you're not having enough power to run the system then it will shut down due to the lack of energy. High-end CPUs and high-end graphic cards require powerful high-end power supply unit that require more power which would be a thousand Watts or more than that depending what are you running. Yes if your system consistently shuts down you need to look into a more higher power supply

    Nice upgrade

    Upgraded my son’s gaming computer from a Corsair 650 to this bad boy. Great reviews online. I love that it is modular and you can leave out any cables not needed. Definitely helps with cable management. It is also nice that it has two CPU power cables for the larger ATX boards. Platinum rated and it has a nice zero RPM mode so you do not even have the fan on if it isn’t needed. Also one of the few PSUs with RGB fan if you are looking to add color to your rig. It is big though, being 1000w, so make sure you have space for the unit and the cables being plugged in behind it.

    Top of the Line PSU

    Does it's job. Relatively quite. Using it with an RTX 4080 Super, and have had no issues.

    Quiet, Powerful, and Smart (Just Gotta Deal with i

    Runs whisper-quiet and delivers stable power, even under heavy workloads. Fully modular design makes cable management easy, and it’s smart enough to report usage stats to your system—though, unfortunately, that requires iCUE. Still, a rock-solid PSU for high-demand builds.
