Xidax X-8 Gaming PC: Power Consumption & Noise

Before bringing this article to a close, we'd like to cover a couple of final data points -- namely, power consumption and noise. Throughout all of our benchmarking and testing, we monitored acoustics and tracked how much power our test system was consuming using a power meter.

Total System Power Consumption And Acoustics
Tested at the Outlet
Our goal was to give you an idea of how much power each configuration used while idling and also while under a heavy workload. Please keep in mind that we were testing total system power consumption at the outlet here, and not of any one individual component.

We measured the load wattage on this system by running a combination of Prime95 and Furmark for an extended period of time, and then taking note of peak usage. This is not something we recommend trying at home—taxing your components in this manner will generate a lot of heat, which is the enemy of electronics. We only do it here to get an idea of an absolute worst case scenario.

Xidax X-8 Power

At idle, the X-8 drew 160W from the wall, about 30W more than Cybertron's CLX RA. When fully stressed, it peaked at 854W, much of which went to the two GeForce GTX 1080 Ti cards. This is one of those configurations where it's a good idea to have a high wattage power supply—in this case, a Corsair RMx series 1,000W.

Cats are optional when running FurMark.

While 854W seems uncomfortably close to the PSU's limit, it only hits that peak when redlining the CPU and both GPUs for a period of time, and before heat buildup causes them to throttle. In real world usage, the X-8 draws far less power.

Noise Output

The X-8 is not a loud machine as configured, but it's not silent either. There are a bunch of case fans—three in front, three up top, one in the rear, and three that are attached to the Alphacool Eisbaer 360mm liquid cooler. If you count the fans on the graphics cards, there are a dozen total.

That's a lot of fans, but none of them spin very fast so it doesn't sound like a windstorm. The one exception is if the GPU fans kick up to 100 percent. It never happened during our benchmark run, but if you use a custom fan profile or crank them up manually through a third-party utility, you'll find that they can generate quite a bit of noise. Otherwise, the noise level stays pretty constant and unassuming.
