5 out of 5 eggsPretty much a perfect HTPC platform

Pros: Small form factor, quad core, ninja silent.

Cons: like others have mentioned it would be nice to have mSATA as I have mine in a very small case. not a deal breaker though.

Other Thoughts: I have this mobo in a Ecosmart case. I chose the Kingston 4GB ram from the Asrock approved memory list. Also got a Mushkin Chronos 240Gb SSD. Currently using the ac adapter from my wife's Gateway laptop. its a 60w, plug is 5.5mm btw.

Win7 installed perfectly off USB on the first try, never had to mess with anything in the BIOS. DLed the drivers off the Asrock site and that was that. Overall build and initial setup took maybe an hour. I'm running WMC and MediaBrowser3 with an eternal 3TB HDD.

Really impressed with this board. Everything is running great. No issues with build or software.

3 out of 5 eggsGreat for 24-7 Linux HTPC / Home Server

Pros: In summary: Basically the best 24-7 HTPC / home server board currently available. Best balance of energy consumption, practical computing power, and initial cost of any board I've seen.

I bought this board/CPU for use as a low-power 24-7 home server and HTPC, and, for those purposes, it's nearly perfect. In general, the integrated graphics processor is fast and snappy, and the system feels just as responsive as it would with any modern i3, i5, or i7. Ubuntu Gnome 14.04 runs nearly flawlessly; the Gnome UI feels smoother and more responsive on this system than it does on my laptop which has an Intel i3-2350M with the HD 3000 IGP. All video playback is flawless, including high-bitrate 1080p h264, even while the system is under load. XBMC runs perfectly with no issues using the default Confluence skin. SNES, NES, and N64 emulators all run perfectly at full speed.

I chose this ASRock board because it is the only J1900 board with DC input and an on-board power regulator. With DC input, the system uses very little energy--significantly less than the non-DC versions of this board, with which quite a few watts of electricity are lost to inefficiency. For my power supply, I'm using a 90W Fujitsu CP360065-02 which was about $10 shipped. This 90W power supply is more than enough to power my system, which includes one SSD, three 3.5" WD Red mechanical drives, a bluetooth dongle, and an IR receiver.

Other pros:
- Uses less electricity on average than a single energy-saving lightbulb
- ASRock's UEFI offers a great fan speed control option which helps to make the system very quiet.
- The UEFI Internet update feature is nice, although it required a few tries before it actually worked.

Cons: The single biggest issue I've had with this board is that when the hardware configuration is changed in some way, e.g. a new USB bluetooth dongle is plugged in, the system occasionally hangs after a warm reboot (via the reboot command) before reaching the grub bootloader. Strangely enough, this also sometimes happens if the partition configuration of any of the connected drives is changed, even if the boot partition is not touched. This is extremely inconvenient when it occurs because it requires physically rebooting the system with the power button, which is a major problem if you're using the system as a remote server. I don't know if this is technically a software issue with Ubuntu and its current Linux kernel (12 September 2014) or not, and it may be fixable with a BIOS/UEFI update, but this does not happen on any of my other motherboards. This issue does not occur from a cold boot (that is, fully shutting down and then turning the system on again), although that is useless for the purposes of remote administration. My theoretical solution for Ubuntu 14.04 is to add the kernel parameter reboot=p to GRUB_CMDLINE_LINUX_DEFAULT (GRUB_CMDLINE_LINUX_DEFAULT="quiet splash reboot=p") in /etc/default/grub and then run update-grub2 as root. (I'm not yet sure if this works, but I haven't had the issue since implementing the fix.) Although this may just be a Linux issue, it doesn't happen with any of my other systems, so I took an egg off for it.

Other cons:
- included UEFI is a user interface disaster. Some menus are very unintuitive.
- "Intel USB3.0 Mode", when enabled, seems to interfere with some IR receivers. Disabling this sometimes helps.
- VGA port is scarily flimsy due to the way it's attached to the board; I feel like I could easily break it with my fingers. Wish it were reinforced somehow. DC port also seems fragile, would be nice if it were reinforced. Not a big deal if you keep this on a shelf in a media center, but if you have kids or pets or some other real-world household nuisance, flimsy ports are a disaster waiting to happen.

Other Thoughts: - Ubuntu's live CD and the freshly-installed system both ran terribly, which worried me at first. After updating and rebooting the installed system, everything ran just fine.
- UEFI Internet update option failed multiple times before finally working
- Didn't include an internal speaker or "buzzer", although that sometimes comes with your case. I had to use a buzzer I had left over from an old PC.
- As of September 12, 2014, I occasionally receive a kernel panic in Ubuntu 14.04 when unplugging and replugging my USB IR receiver (included with Rosewill RHRC 11001 remote) while lircd is active. This is probably a software issue with Ubuntu but I haven't had time to test it.
- J1900 CPU is obviously more sensitive to resource-intensive tasks than beefier chips, although it's many times better than something like the Raspberry Pi or similarly underpowered embedded systems. e.g. When running Nautilus in the background during my first boot, Totem video thumbnail generator caused the system to stutter and thrash intermittently while trying to generate a thumbnail for a corrupt video file--a real-world example of when having a faster CPU would have made a big difference.
- The first SATA 3 port is seen by the operating system as the second of the four SATA ports on the board, which means that most Linux distros assign the first SATA 3 port the device map of /dev/sdb. The problem with this is that some installers are too stupid to install the bootloader to /dev/sdb by default, even when the root partition is on /dev/sdb, which means that some users might have issues if they don't keep this in mind during during the installation.
- If you're using the Rosewill Legacy v6 case, you'll need a 15-pin SATA power extension cable to attach one of the top drives to the SATA power header on the motherboard. $5 or less.
- Probably far too slow for 4k video, and no hardware decoding of 4k video with Bay Trail as far as I'm aware (unlike some of the higher-end Celeron-branded Ivy Bridge / Haswell processors). I plan to relegate this to server-only duty once 4k really catches on, although I don't think that will be for many years to come.
- You can probably configure another system to have similarly low power draw through undervolting and clever configuration, but this is a great out-of-the-box solution for the typical HTPC/home server use case.

4 out of 5 eggsSilance at Last

Pros: This board is cool and silent, which is great for a computer that needs to be on 24/7 and is in a bedroom. I thought it was going to be a little slow or sluggish, but it really is not. I’m mainly using it to capture video from IP security cameras and as a mini file server. 1080p video playback is flawless. Streaming and file transfers work great.

4GB Ram, SSD for Win 8.1 and 2 4TB HD.

Hope to be getting another one soon to use for everyday tasks like surfing and office.

The last ASRock motherboard lasted a long time, hope this one does too.

Cons: The only thing I can think of is I with it had onboard WIFI and a mSATA slot.

Other Thoughts: None. Board works great.

5 out of 5 eggsMakes easy cheap cool low energy full service ITX Win8.1 builds

Pros: This is my 4th AsRock ITX board build. It is my 1st fan-less completely solid state build that works well for general and HTPC use even compared to my Intel Ivy Bridge i7, i5 and AMD A10 ITX (all 65 Watt TDP processors) builds. The main practical daily usage difference I see is step-wise slowing on high processor demand admin tasks like Win8.1 OS virus scans, backups and OS updates. with the J1900 being the slowest. Boot times are fast with all processor and board combos. Built in graphics all quite similar. Same for 7.1 audio. I replaced a Sony 6.1 AV receiver with the Q1900DC-ITX HTPC build and noted little difference in audio quality. For the case I used a Fan-less, Compact Morex 557 Universal Mini-ITX Case. Tiny, lots of natural ventilation and barely warm to the touch when the Q1900DC-ITX build is running. All this for approx 35-40% of the i7 ITX build. Wow.

Cons: None so far

5 out of 5 eggsIt was worth waiting a couple of years for

Pros: I'm using this as a linux-based HTPC with XBMC/MythTV. I'd been waiting for a silent, low-wattage multi-core CPU board (a real one - not an Atom!) with capable on-board graphics. With an SSD this boots in several seconds and UI performance and HD video are great. I fashioned a servicable case out of the box this thing came in. The direct DC connection is icing on the cake.

Cons: requires connected LED if you wand a power indicator (not really a problem as the RJ-45 jack lights work well enough for this).

Other Thoughts: I just ordered a mini PCI-e AC wifi/bluetooth 4.0 card + antenna for a bit over $30 .

4 out of 5 eggsNot quite plug and play

Pros: Powered by surplus laptop brick
fanless
4 x SATA ports (2 x SATA2, 2 x SATA3)
VGA, DVI, and HDMI video

Cons: None that I don't expect to be cured with updated alternative OS software

Other Thoughts: I bought this to make a fanless sealed box NAS server with 2 x 4 GB PC1333 laptop memory and 2 x 2TB NAS disks. Had to disable USB3 ports to boot FreeBSD 9.x as found in FreeNAS and NAS4Free. I could backport kernel patch and build from source, but I'll probably limp along without USB3 and keep playing until FreeNAS makes it to FreeBSD 10.

FreeNAS bigots insist on ECC for ZFS, and these consumer Bay Trail-D boards don't have it. Buy a server board with an Avoton and 16+ GB ECC memory if you want to do things the "right" way. I am willing to experiment with this consumer board with a pair of mirrored ZFS disks.

I hope ASRock sells a lot these fanless DC-powered Mini-ITX boards, and that other MB makers follow suit. ATX and even SFF power supplies are not good matches for these <100W systems (including disks). I know one can use the popular DC - DC converters to power ITX boards with 24 pin ATX interfaces, but I prefer to be able to use laptop bricks directly.

Just for fun I installed Linux Mint 17 (xfce) on an SSD on this board, and it just worked. Boots in around 15 seconds with absolutely no fiddling. Result: instant desktop / browser computer. I'll probably try XBMCBuntu at some point to see how it might function as an HTPC

Came out of the box with UEFI secure boot disabled, so no trouble booting non-Windows OS's. Didn't try any Windows OS's.

Other things I plan to try are using the Serial and Parallel port headers for talking to various pieces of industrial gear.

5 out of 5 eggsReview update power

Pros: Fast low wattage motherboard, everything worked first time. Stable as a rock.

Please see other thoughts for update

Cons: Noda

Other Thoughts: After i rote my first review i tested this motherboard with a 12v power supply. Acuity 4 different 12v power supplies . What i found was both boards us the same amount of power with a 12v power supply. The 19v power supply uses less watts yet more amps so in the end it works out the same. Using this board with built on power saves room though still uses the same wattage as the ASRock Q1900-ITX . So the max with a 120fan and 3 laptop drives Amd 16gigs of memory , the max power though just for a split second is 27.6w at 12v for both motherboards , average 19w with idle as low as 11w

Also i had used the windows installs from the ASRock Q1900-ITX hard drive. I assumed since there almost identical boards i could just take the SSD out of the ASRock Q1900-ITX and use it in this board. That was incorrect and after my first review i was getting window errors and i did fresh installs of windows 7 and windows 8.1 and found virus scans to use half of what i reported last time in my first review , depending on the program. Yet non of them i tested 8 in all went passed 50% , most stayed closer to 20%-35% very impressive


windows ie score did not improve , the overall system was faster with fresh installs and everything works

5 out of 5 eggspowerfull low wattage

Pros: this board benchmarks and scores and runs the same as the ASRock Q1900-ITX, yet this board uses on average 9 watts less from its onboard power. it power to spare for a HTPC or home server with super low wattage.

Cons: noda

Other Thoughts: I have this board and the ASRock Q1900-ITX. wish I had waited and just purchased 2 of these.

there identical in just about everyway yet because of this boards onboard power it uses even less power.
yet there both excellent and perfect candidates for a HTPC or home server. the 4 cores handle everyday tasks with ease. serfing online about 0% - 4% cpu usage. windows 7 64bit Norton virus scan uses 45% - 50%. this is great considering last years dual core Celerons virus scan used around 98% - 100% and we all now how much cpu Norton uses . I don't actually use Norton , just for a test. webroot antivirus the best.

it can multi task just make sure you have enough memory. I see most people with 4 to 8 gigs. I tried that though when i upgraded to 16gigs of memory much more fluent and more able, hard pressed to tell the difference from my i3 or i5 for everyday tasks. I have had 4 programs working at the same time with no slowdowns or issues

using a 19v 90w power brick these are the wattages I averaged with this motherboard and 16gigs of memory at 1333mhz spd of 888,23. T1 at 1.35v and 1 SSD and 1 500gb laptop drive and one fan using HDMI port at 1080p

on start up 13w - 20w
idle 11w
webroot virus scan 16w

ASRock Q1900-ITX with a 98% efficient power supply

start up 19w - 26.6w
idle 16w - 17w
virus scan 19w- 24w
i also tried a mini pico 150w psu on the ASRock Q1900-ITX and the wattage did go down on average 3 watts from the standard high efficient seasonic psu
both boards run windows 7 and 8 no issues, you just have to know how to set the bios up for each operating system. there is hardware security built into these new Celeron motherboards that must be disabled in order to run windows 7.

As for Linux not there yet. though mite try one as a firewall router appliance. should work great with power to spare even for a large 100+ installation

I had no issues at all from start to finish and ram voltage options in the bios go from 1.25v to 1.65v

win 7 64bit WEI score 5.0
cpu 6.4
memory 7.7
graphics desktop 5.0
graphics gamming 5.9
hard disk 7.9

windows 8 64bit even faster

I very happy with this board

5 out of 5 eggsNice Board!

Pros: Quality board.
Makes for excellent HTPC without noisy fan.

Cons: None really...Wish it had a mSATA slot for SSD.

Other Thoughts: Will run a full bandwidth Blu-Ray movie at about 50% CPU with H/W acceleration. Plenty of power for a quiet HTPC.
