Intel D54250WYKH Haswell NUC Kit with 2.5" Drive Slot Mini-Review
by Ganesh T S on May 18, 2014 10:15 AM ESTPower Consumption and Thermal Performance
The power consumption at the wall was measured with the display being driven through the mini-HDMI port. In the graphs below, we compare the idle and load power of the D54250WYK with other low power PCs evaluated before. For load power consumption, we ran Furmark 1.12.0 and Prime95 v27.9 together.
In order to evaluate thermal performance, we first ran our test for load power consumption and made sure that the unit wasn't getting throttled. Given that the D54250WYKH is an actively cooled system, it had no problems passing this test. In order to determine the efficiency of the cooling system, we first loaded up the CPU alone using just Prime 95 for around 30 minutes. This was followed by addition of the GPU load (FurMark) for another 30 minutes, and then removal of the CPU load for 10 minutes. The system was then left idle. The various frequencies and temperatures during this loading process are recorded in the graphs below.
We find that under pure CPU load, the maximum temperature inside the system was less than 80 C. With both CPU and GPU loading, we see the DRAM temperatures rise, but the CPU package temperature goes down. Looking at the frequency graph, we find that the cores and the GPU adjust themselves to stay within the thermal budget (this doesn't show up as thermal throttling in the hardware monitoring programs as the temperatures are nowhere near TJUNCTION). After removal of load, temperatures get back to idling (around 40 C) in less than a hour.

I use a Haswell core i3 version of the Gigabyte Brix with a OCZ Vertex SSD and I really like the system. Great form factor and mounting it behind the monitor makes for a very clean system. I don't think I'll go back to a different form factor for normal desktop systems again.To reply to the issue with the Intel AC760. I replaced the standard wifi card in the Brix for a Intel AC760 version. I use the standard drivers from Windows 8.1. I cannot reliably connect to the 5 GHz network of my Asus AC66u router. It works OK on the 2.4 GHz band, but I'm a little disappointed in this. Seems the drivers definitely need to mature.

This nuc is only good if u want to turn your dumb tv into a smart tv that's smarter than all tv's with built in smart functionalities. Gaming on ULV graphics = boooooooo. If you want to game in this tiny form factor you should get an amd apu. 5000 blowsdblagent - Monday, May 19, 2014 - link
Quick question that I assume I already know the answer to, these will support dual video output correct? I assume they will, and if so then I could see moving my entire office over to these in the future. I just built 40 desktops and building these would be a world easier.They all have Samsung SSDs so this new 2.5 form factor support will be a savior, though I'm set for several years now. Maybe as I get some more users I will build these over my custom built solution. Would save me some grey hair!

Am I the only person who would like to see a single slot Pci for the 750 ti from nvidia in something this size?. I realize it would increase the power envelope, but it would also make gaming practical. AMD is supposedly working on a competitor for the 750 ti and this would give the purchaser a better set of options.run - Monday, May 19, 2014 - link
The hard disk is where the operating system and all software applications are stored. Because of this, a properly working drive is essential in the operation of any computer or laptop.CSMR - Tuesday, May 20, 2014 - link
Questions:1. How well damped is the 2.5" hard drive cage? I think this is mainly for regular HDDs (since you get mSATA for SDDs) so I am interested in how noisy HDDs are in this case.
2. The TrueCrypt benchmark doesn't look so good. Does this suggest that with native Windows whole-drive encryption, that encryption will limit read/write speed? I would have expected with AES-NI to get hardware encryption and decryption at closer to the SATA limit of 6Gbps.

ganesh, have you tried installing windows 8 via uefi msata gpt on this intel nuc? i updated the nuc bios to 25, but the msata (crucial m550 256gb) is still undetectable via uefi. shows up just fine in legacy bios. wondering if this is a nuc issue.prophet001 - Wednesday, May 21, 2014 - link
It was a mission to find out what NUC stood for. Might want to include that in the future.:)

This article seems to imply that the D54250WYKH model has only the 2.5" drive bay available for storage and no MSATA slot. Based on info I've seen elsewhere, I was under the impression that the D54250WYKH model will accept an MSATA drive on the board AND a 2.5" drive in the bay...so one could have say a Crucial M550 MSATA as the boot drive for OS and programs and also contain a 2.5" HDD or SSD for additional storage of data, music, video, etc. Can anyone confirm this?Jas448 - Saturday, May 31, 2014 - link
I have installed windows 8.1 to a Crucial 240 M500 msata and using a sanDisk SSD250Gb as a 2nd drive in the 2.5 inch bay. No problems at all. The only problem I had was Windows would not install from a USB3 flashdrive but would from a USB2 Flashdrive
