ASRock Z170 OC Formula Motherboard Review

Temperature and Power Consumption

Power Consumption

Using a P3 Kill-A-Watt we monitored the power usage of the ASRock Z170 OC Formula system during our testing and made note of the lowest and highest readings.



Legit Bottom Line:  The ASRock Z170 OC Formula was using a tiny 2W more power than the other Z170 motherboard we have tested at Idle conditions.  Once we started gaming though the ASRock Z170 OC Formula was found to be using 5W less than the other Z170 motherboard.  Not a big difference in power usage either way.  Of course overclocking the Z170 OC Formula the Idle and Load power usage went up a bit, 12W during Idle testing, and 39W while gaming.  Not bad overall.



To monitor the temperature of the CPU, we used CPUID Hardware Monitor 1.28.  It tracked the Minimum and Maximum temperatures for all four cores, which was then averaged.  The Idle condition temperature was done by allowing the system to sit at the desktop with no applications running.  For the Load temperature score, we ran through all the various benchmarks included in this review, and played a couple of games for an hour.  The ambient temperature in the room was kept at 21C (70F).


Legit Bottom Line:  Temperature wise, both Z170 motherboards we tested received pretty much the identical temperature readings throughout testing.  While overclocked though, the Z170 OC Formula averaged over 90C while gaming, that is pretty high, and wouldn’t recommend keeping it there for long term gaming.

    I’m just gonna outright say it. If you are from Pittsburgh, this is a really tempting board just for the design!


    Maybe I just do not understand the idea of it all, but how are you supposed to have quad graphics cards and still be able to utilize all four cards respectively along with three M.2 drives in a raid??

    Does this not take up more than the available PCI-E lanes allocated for the GFX/disk/HDD’s? I could see with a 2011 socket allowing 40 lanes of PCI-E 3.0 there being no problem…..I just hope someone can enlighten me as I’m always looking at tech just to see what’s avaislble for the ol’upgrade…

      you the real MVP
      maybe this socket will be used for future generation of cpu on this soket, that will have more pci lanes


        I see in the specifications of this particular motherboard here on this review it has an * (asterisk) next to where it explains the PCI-e throughput. It does not however explain what that asterisk means in lieu of the PCI-e lanes in question.

      It seems that each motherboard does it a bit differently. The GB Z170 board specifically mentions that the PCI-E lane and SATA ports becomes disabled, where the ASRock Z170 OC doesn’t mention the PCI-E lanes, but does mention disabling the SATA ports. Another one I’m testing is like the ASRock board, only disabling the SATA ports. That seems to be the most common aspect of the M.2 implementation.


        Nice. And thanks for shedding a bit of light on this for me. Just did not understand the asterisk by the explanation of the PCI-E lanes in the article clipping they took from the manufacturer. I sure there was something elsewhere explaining exactly what that was supposed to mean…

          Sorry, I’ll watch those next time. The * on the PCI-E slots is just that they support NVME as boot drives, nothing to major.

          Ah’thank you….
