Intel NUC Kit D54250WYK Review – The NUC Gets Haswell Power!

Jump To:

Power Consumption & System Noise

idle-power

With the Intel NUC Kit D54250WYK running Windows 8 the entire system was consuming just 4.6 Watts of power from the wall outlet! This test was done with the Haswell C8/C9 low-power states enabled. The old Ivy Bridge NUC ran over 6 Watts at idle without a wireless card, so we are seeing a significant power reduction at idle. Having your entire desktop PC running under 5 Watts at idle is awesome!

(Click here to see how low we can get the idle Wattage when you take out the wireless card, remove a DDR3L memory module and drop the DRAM voltage down to 1.325V.)

load-power

At full load the NUC was found to often peak around 25-26 Watts in CPU+GPU intensive applications like the Cinebench GPU test and 3DMark11. Not a bad power draw from a very capable desktop computer and shows that the carbon footprint of running the NUC is very small. It is clear that consumers want to be green these days and energy efficiency is a big deal.

nuc-idle-sound

With the Intel NUC turned off we found the ambient room noise to be 31.9dB. With the system up and running on the desktop in an idle state the system was observed to be right at 39.0dB.

nuc-load-sound

With the NUC fully loaded running Prime95 27.9 64-bit we were seeing 43.4dB from about 5 inches away. This is an increase of 4.4dB from idle to full load, which isn’t that bad at all.  In a quiet room you can hear the single case fan spinning, but once you have some background noise and you can barely hear the fan slowly spinning when the NUC is running! The Intel NUC comes set to ramp up the fan at 78C, but with the room at 21C we were unable to get the NUC hot enough for the fan to kick into high gear. The top of the NUC gets warm, so let’s take a look at the temperatures.

idle-temperature

When it comes to temperatures, we used Intel’s Extreme Tuning Utility to monitor temperatures and voltages. The Intel Core i5-4250U processor idled at 0.6870V with a core temperature of 36C.  Idling at 36C is a very good temperature for the small HSF used on this 15W TDP processor! The GPU was at 39C!

load-temperature

We fired up Prime 95 and we saw the CPU Core Voltage jump up to 0.8650V and the CPU Core Temperature rose to 77-78C.

load-testing
 
We launched up 3DMark11 when Prime 95 was running to try to load up both the GPU and CPU and found that the CPU temperature actually dropped down to the high 60′s and the GPU temp was up in the low 70′s.

    I thought external drives are not meant to fitted internally… or am I missing something?

    Hi,

    great report!! Do you have any experience with SATA DOM Elements with this Intel NUC Kit??

    If you want to use Wi-Fi be warned about pretty much all Intel Centrino cards like 6205//6235/2230/

    8 months and 67 pages of complaints and still these cards dont work!!!

    I wish i knew this before i bought mine or i would have bought Mac Mini :(

    HI Nathan, Thanks for the review. I recently purchased the D34010WYK model, and I have a 2.5in SSD that I would like to use. Would you happen to know where I can find small enough cables to use, which will allow this SSD to fit in the NUC?

    Thanks in advance!

    Cannot install win 8.1 – need to load a AHCI driver since the sata controller cannot be found using native drivers and the one extracted from the 500 mb November driver bundle isn’t sufficient :(

    Hi !
    I would be very interested to know which Intel 5000 HD in integrated on the 4250U.
    As here is many references. Is it the entry model one? Or am I mistaking with the other name of the HD 5X00 series?
