No matching power supply available, please check your configuration. That and the closest a given power supply is to its max load output, the lowest the efficiency. That said, most of us won't highly stress our systems all-around the clock unless you somehow have the time to constantly play games.

Gaming can be seriously taxing on your PSU since they will generally fully load your graphics card, which is likely the most thirsty part of your setup.

To get an idea of what your system, or dream upgrade, will look like in terms of power draw you can easily enter all the particulars into a handy PSU calculator. The most accurate way to determine your system's power needs is to use a kill-a-watt device and take some readings under full load, that's useful if you want to replace the existing PSU.

Note that this procedure will only give you an indicative reading since it doesn't take into account your PSU's efficiency. Unfortunately, the manufacturers do not provide clear information on the actual GPU power consumption, and to make matters worse, you also have to consider possible power spikes that can reboot the system if the PSU isn't strong enough to handle them.

Even at default settings, some high-end CPUs can ask for W or more power. Yes, we're looking at you Mr. Core i9 K.

If you combine this with a high-end GPU's power consumption, you will quickly figure that you need an W or even stronger PSU for a high-end gaming system.

The PSU's dimensions play a role in your next system build.
