Xotic PC Executioner Stage 4 Gaming PC Review

Overclocking, Noise, and Power Consumption

Xotic PC will overclock your system for you, including the GPU, for a fee. If you're savvy enough, you can save yourself a few bucks and overclock the system on your own, which is what we did with the Executioner. Our goal wasn't to go crazy and squeeze every ounce of performance out of this system, but to boost the CPU with some simple tweaks and see how it fared. Like most of Intel's processors post Sandy Bridge, the new Haswell-E based processor Xotic PC employed here offers limited flexibility when overclocking via BCLK (Base Clock) manipulation. If you want to tweak CPU and memory frequencies via the BCLK, it can only be increased by a few MHz at a time before things get wonky.

We should note that our testing at this clock speed was limited to multiple, repetitive runs of Cinebench R11.5. Though the system remained stable during testing, other usage models and test conditions may or may not have resulted in anomalies. Regardless, for just a quick preliminary look at available CPU headroom with Alienware's liquid cooling solution, the following are our results.

Xotic PC Executioner Overclocked

We settled on overclocking the CPU to 4GHz by bumping the multiplier up to 40 on all cores and increasing the voltage. Attempts at hitting 4.5GHz and higher proved unfruitful with basic tweaking, though if you're willing to put in the time, you should be able to go higher than 4GHz. Nevertheless, it's a nice increase over the CPU's base 3GHz and Turbo 3.5GHz.

Xotic PC Executioner Cinebench Overclocked

Our modest overclocking efforts gave us a 10 percent improvement in Cinebench -- not shabby for minimal effort. And again, if you're willing to spend some time tweaking the many options inside the ASUS X99-Deluxe's BIOS, you should be able to coax even more performance out of this setup.

Tested Power Draw From The Wall Outlet At Idle And Under Load
Before bringing this article to a close, we also decided to look at power consumption. To test the power draw, we let the system sit for several minutes after booting and recorded the wattage for our idle measurement. We then ran a dangerous combination of Prime95 and FurMark to fully stress the CPU and GPU and let it run until the wattage no longer increased. This gave us our load rating.

Xotic PC Executioner Power Use

The Executioner Stage 4 is pretty well decked out with dual graphics card, two storage devices, a high-end CPU, and a water cooling setup. Even so, it didn't burn a hole in our wall as might expect. Instead, it pulled 523 watts at a full load when taxing both the CPU and GPUs for an extended time. Given that Xotic PC included a 1100W power supply, you can see there's plenty of headroom here for future upgrades, even if you want to another GPU to the mix.

A Note On The Executioner Stage 4's Acoustics:

No joke, you could lug this thing inside a library and game at 4K resolution with all the settings cranked up and not receive any complaints. Well, as long as you bring along some headphones. The system itself stays remarkably quiet. Sitting next to it, you can hear the low whir of the fans, but they don't approach anything near what we'd call noisy. It's so quiet that you can sometimes hear the water flowing through the tubes.
