ASRock VisionX 471D (Intel Haswell) Mini PC Review

Temperature and Power Consumption

Here is the kicker, the results for power consumption while the VisionX 471D is overclocked only reflects running Prime 95 and no GPU load like the rest of the results. When I tried to load the GPU (Furmark) and CPU (Prime95) together (when the system was at a 4GHz overclock), the system would shut down, as the AC/DC adapter had reached it OCP trip point. Of course this system was never designed to be overclocked, and the system never shut down during any of our normal CPU and GPU workloads (even when overclocked).

 

This isn't really a big deal since no program I encountered was able to shut the system down. Overall the system was quite impressive, and while the power consumption is much higher than the SFF PCs listed, the performance gains are huge. None of the SFF PCs have an Intel quad-core i7 CPU, a discrete GPU, or 3 drives (mSATA, 2TB HDD, and DVD drive), but all together I would say that power consumption is kind of low compared to similar desktops with close to the same performance.

Shot of the front of the VisionX 471D idle and load, at stock.

Shot of the back where the exhaust fan is at idle and load, at stock. Notice the exhaust temperature is higher here than when the system is overclocked and at load (below) and that is because the fan wasn't blowing at full speed like it is when the system is overclocked, plus there is a GPU load here that isn't present below because of power restrictions.

This is a shot of the front of the unit at idle and at load, when the system is overclocked with the 4GHz profile in the UEFI. The fan is blowing full speed the entire time.

This is a shot of the rear exhaust of the unit at idle and at load, when the system is overclocked with the 4GHz profile in the UEFI. The fan is blowing full speed the entire time.

 

The temperature increases are smaller when the system is overclocked because the fans are set to blow 100% 24/7, but with the stock UEFI profile, the system stays pretty quiet the entire time.
