ZOTAC introduces two new ZBOX Mini PCs|
September 14, 2017
By Aleksandar Kostovic
ZOTAC have introduced two variants of their ever-growing Mini PC lineup.
The first one is called the ZBOX MI553. It features 7th Gen Intel core processor, Intel Optane memory support and Thunderbolt 3. This Mini PC is actively cooled and has large ventilating surface area. It is equipped with an i5-7300HQ, with Intel HD Graphics 630 and up to 32GB of DDR4 2400MHz RAM.
The MI553 chassis measures 184 x 184 x 72mm, only slightly larger than a Mini-ITX motherboard. Inside the chassis is an interesting motherboard design with a 2.5in drive bracket and the large side blower fan mounted to the CPU.
Next up we have the ZBOX PI225 with another new form-factor. Zotac advertises this one with the bold title of "world's smallest". And indeed it is. Measuring at a mere 0.05 litres (8 x 95.4 x 63mm) it is smaller than your average smartphone.
Despite its miniature size it still packs a punch. The Apollo Lake Celeron N3350 is clocked at 2.4GHz and the 32GB onboard eMMC storage and 4GB of LPDDR3 RAM will be more than enough to handle everyday tasks such as web browsing, video streaming and content consumption. As far as connectivity inside this little marvel goes it has two USB 3.0 type C ports, 802.11/ac Wi-Fi, Bluetooth 4.2 and a Micro SD card slot.

pfSense to require AES-NI from 2.5: how it affects you
September 08, 2017
Earlier this year Netgate - the maintainers of pfSense, the popular open source firewall/router distribution based on FreeBSD - announced that they would be dropping support for CPUs without AES-NI starting from version 2.5.
AES-NI is an extension to the x86 instruction set used to hardware-accelerate AES encryption and decryption.
Desktop CPUs have supported AES-NI for several years, though the lower power consumption Atom and Celeron CPUs used in many Mini-ITX boards and appliances have not until more recently.
How does this affect my existing Mini-ITX pfSense Firewall?
It won't, unless you want to upgrade. If your CPU has AES-NI, you can continue upgrading to 2.5 and beyond. If your CPU does not support AES-NI then you will be able to go no further than 2.4, which will still be available for download. Support for 2.4 will continue for many months afterwards and of course your firewall will continue to function, though without any features introduced from 2.5 onwards.
If your motherboard has a CPU from the following list it has AES-NI:
N3050, N3150, N3160, N3350, N3450 and later
If your motherboard has a CPU from this list it does NOT have AES-NI:
D510, D525, D2550, N2600, N2800, 845, 1047, J1800, J1900, N2807, N2930
If you don't know your CPU type it will show in your pfSense dashboard. We can't list every CPU here. Intel owners can check on ARK whether their processor supports AES-NI: type "ark" followed by the CPU name into Google and look for "AES" on the first resulting page. AMD owners may want to try their luck with cpu-world.com
When will this happen?
At the time of writing, 2.3.4 is still the official release and later versions are still in beta. pfSense 2.5 will be built on FreeBSD 12 - which won't be released until early/mid 2018. A pfSense 2.5 release is most likely much later in 2018.
Are there any alternatives to pfSense?
There are many. VyOS, Untangle, IPFire, Sophos UTM, ZeroShell, Shorewall, DDR-WRT to name but a few... or plain old IPTables.

Gigabyte's GTX 1080 Mini ITX OC 8G Graphics Card
September 06, 2017
By Aleksandar Kostovic
As the demand for smaller and more powerful Graphics Cards grows, Gigabyte have launched a bigger brother to their already existing GTX 1070. The 1080 Mini follows the same footprint: Dual slot thickness, 131mm height and 169mm length.
This card gets an upgraded power delivery system with 5+2 power phases (from 5+1 of Founders Edition cards). TDP is up to 180 Watts, slightly more than the 150 Watts of the 1070.
The card is powered by one 8 pin connector and it keeps the same look as the 1070 model, with the same heatsink and semi-passive 90mm fan which only kicks in when a pre-determined load or temperature is reached.
As far as the clock speed goes, it can go a bit faster than a founders edition in OC mode, and like the previous model it has two modes: Gaming and OC mode. But of course boost clocks will ultimately be determined by the temperature, ambient temperature and airflow in your case.
ASRock launches DeskMini GTX/RX mini PC with GTX 1080
September 05, 2017
By Aleksandar Kostovic
Two years ago Intel introduced their desktop-CPU-on-tiny-motherboard 5x5 form factor, later re-named as "Mini-STX".
ASRock subsequently launched their first generation DeskMinis and have now introduced their second generation called the DeskMini GTX/RX, this time with a newer and very slightly larger Micro-STX form factor.
This tiny PC is able to pack up to an i7 processor, 32GB of DDR4 SODIMM memory, two SSD or HDDs, triple M.2 SSDs and a discrete graphics card in a size of only 2.7 litres.
One of the most interesting aspects of this PC is the MXM GPU slot. Mobile PCI Express Modules have generally been found to date in some higher end laptops and All in One PCs.
The 5 variants of the GTX/RX so far listed are fitted with: a B250M-STX board with MXM slot, a Z270M-STX board with MXM slot, B250M-STX with GTX 1060, B250M-STX with GTX 1070 and B250M-STX with GTX 1080. It is possible to fit up to B+ size MXM GPU in the GTX/RX chassis.
As the name of this PC suggests, it is capable of housing a GTX 1080 or (slightly further down the line) an RX VEGA MXM graphics card. ASRock are said to be working with Aetina and TUL to ensure a stable supply of cards.
A welcome change from the earlier DeskMini is the all-black PCB with black Mosfet heat sinks.
Gigabyte's Denverton MA10 Mini-ITX motherboards
September 05, 2017
By Aleksandar Kostovic
Lately a lot of details about Gigabyte’s new MA10-ST0 have emerged.
The motherboard has an impressive feature set. There are many and the first (and most exciting) one is Intel's new Denverton Atom chip. This model features the C3958 SoC with 16 cores each running at 2.0Ghz. Meanwhile the chip only outputs 31 Watts of heat.
The MA10 supports up to 512GB of RAM running in dual channel mode (128GB per stick); 10G Ethernet with Dual SFP+ ports allowing up to 20Gbs full duplex encryption with Intel QAT; IPMI 2.0 remote management; a 32GB eMMC memory module for your OS; four Mini-SAS ports - each of which supports 4 SATA ports - giving 16 SATA ports in total; and if all this isn’t enough - a Gen3 PCI-Express x8 slot.
Given the 10G Ethernet and impressive number of SATA ports, this motherboard is clearly aimed at the cold or edge storage market.
Word on the street is there will be another model called the MA10-ST1, likely with a Dual Core C3338 SoC, 2x 1GB LAN, and 2x DDR4 RAM slots.
And if this one doesn’t quite have the right spec for you, other server board manufacturers will soon be joining the Denverton party with variants on the same theme.
Guide: Choosing the right DC-DC PSU
September 05, 2017
By Aleksandar Kostovic
With the increasing popularity of DC-DC power supplies, we have made a guide to help choose the right one for your needs.
In the context of computer motherboards, a DC-DC converter accepts a single DC input and converts it into the very stable voltages that a motherboard needs to operate (generally 3.3V, 5V and 12V, though some boards only require a single regulated voltage). A DC-DC converter will always be paired with either an AC Adapter (aka 'Power Brick') or a DC voltage from another system such as a battery.
The advantages over a standard ATX power supply are twofold: reduced size, and reduced noise as DC-DC converters are almost always fanless. ATX power supplies have the upper hand when larger amounts of power are required. We probably won't be mining any bitcoins using DC-DC converters any time soon.
How many Watts do you actually need?
We will often total the maximum power consumption of each component to calculate the power draw of a system under load. Thermal Design Power or TDP - though strictly speaking a measure of heat dissipation - is a useful measure for processors and GPUs. Other components such as your SSD and even your RAM will consume more power. And don't forgot those powered USB devices.
Several online calculators exist, though they tend to calculate from the perspective of a traditional ATX power supply. Figures given will often be much higher than real world figures. For example we've measured an H270 Mini-ITX system fitted with i3-7100T processor, SSD and Slim Optical Drive at 23W idle and 32W under medium load.
Some online calculators:
The other thing to note it that no power supply can ever be 100% efficient (DC-DC units are typically within the 90-95% range), so there will always be some Watts wasted in the form of heat.
Our rules of thumb: Any motherboard with an embedded Celeron, Atom etc. will be fine with a 80W or 90W DC converter. If you have a 35W TDP processor a 90W DC converter will be sufficient. A 45W Xeon or 54W Pentium or above will need at least 120W.
Types of DC-DC Converter
We can roughly break down typical DC-DC converters used with Mini-ITX motherboards into Fixed Input, Wide Input and Vehicle.
Fixed Input DC-DC converters will only accept a regulated input. If the PSU is rated to accept 12V it will only accept 12V as the input.
Wide Input DC-DC converters are more adaptive and will take a range of voltages. For example 12-24V, 6-34V, 12-72V etc.
Vehicle DC-DC converters will work with a wide range of voltages and include protection against the rapid changes in voltage cranking an engine can cause. They will often include battery-specific functionality - powering off a computer if a battery has discharged below a certain voltage for instance.
Our rules of thumb: If you are using a battery, get a vehicle capable DC converter. If you have a regulated power source that isn't 12V, get a wide input DC-DC converter. If you are powering from a standard 12V AC Adapter, use a standard DC-DC converter.
PCB-type DC-DC converters
Traditional DC-DC converters are built on a printed circuit board with an input and an output side. This allows them to be easily mounted within a case or sometimes an external enclosure. Many Mini-ITX specific cases use this type of DC-DC converter in conjunction with an external AC Adapter. Power output can be as high as 400W for a custom-designed model, though typically much lower to suit the task in hand.
picoPSUs are a category of DC-DC converter that connect directly to a motherboard's ATX power connector, removing the need for the ATX cable between the DC-DC converter and motherboard.
Fixed Input picoPSUs have yellow pins, the wide input have red and the vehicle capable picoPSUs have blue pins. Power output for official picoPSUs varies from 80W to 200W peak. For edge cases, higher wattage home-grown 'unofficial' picoPSUs also exist.
Our rules of thumb: A 20pin picoPSU will work just fine if your board has a 24pin ATX connector. The additional 4 pins aren't required except in very specific circumstances.
Choice of AC Adapter
If you are powering your Mini-ITX system from a wall socket you will require an AC Adapter. The AC Adapter converts the Alternating Current from your wall socket into a single Direct Current suitable for the DC-DC converter. You will need to pair your DC-DC converter with a suitable AC Adapter. No matter how much wattage your DC-DC converter can output, it will be limited by the power output of your AC adapter, e.g. a 200W DC-DC with an 80W AC Adapter will still only provide maximum 80W of power.
Our rules of thumb: A 80W AC Adapter pairs well with the picoPSU-90; A 150W pairs well with the picoPSU-150-XT. Your AC Adapter and DC-DC converter will need to have the same voltage, plug and socket type to connect. A re-purposed Laptop power brick will probably need a new plug and a wide input DC-DC converter to function.
Video: JBC313 and JBC323 Mini PCs with Dual Intel LAN and AES-NI
October 24, 2016
We have entered the video age and made a short piece about the JBC313 and JBC323 Mini PCs. They are rugged, low power consumption and fanless Mini PCs under a litre in volume with 2x Intel I211-AT Gigabit LAN ports, powered by a Quad Core Celeron N3160 Processor with support for AES-NI acceleration in hardware. The Intel chipsets and AES-NI make these machines ideal as dedicated Linux-based network appliance devices - pfSense advocates in particular will like these.
We plan to make more. If there is something else you would like us to make a video about please let us know in the youtube comments.
Gigabyte and Zotac first out of the blocks with Mini-ITX sized GTX 1070 and GTX 1060
July 13, 2016
PC Gamers have been able to use Mini-ITX motherboards and standard length graphics cards together for a long time, but is has only been fairly recently that short depth “Mini-ITX” high end graphics cards have been available.
Gigabyte’s latest offering is the first card to be announced that usurps the previous king of this form factor - AMD’s R9 Nano - by fitting an NVidia GTX 1070 into a 17cm long package.
The GTX 1070 Mini-ITX OC shares the same Pascal architecture as the flagship GTX 1080 whilst offering 1920 CUDA cores, VR and 1440p gaming support.
To fit into the smaller form factor Gigabyte have made some changes to the GTX 1070 reference design. The card has a 5+1 phase power design (upped from 4+1), a 90mm fan with a custom blade design, and
The card can be run in two performance profiles: Gaming Mode and OC Mode. Both modes are clocked slightly faster than the standard length Founders Edition card.
The card has a semi-passive fan which remains off until a pre-defined temperature or GPU load is reached, keeping noise levels down under light usage. The standard GTX 1070 is a 150W TDP card and we would expect the GTX 1070 Mini-ITX OC to be very similar.
With the GTX 1060 launch only days away, details are emerging from other manufacturers of their variants. Zotac look set to be first out of the blocks in the Mini-ITX form factor with their GTX 1060 Mini, with the ubiquitous 90mm fan attached to an Aluminium heatsink.

Mini-STX (5x5) Roundup
April 05, 2016
It's been a while since we reported on Intel's 5x5 boards - smaller than Mini-ITX boards with full size processor sockets. Here's a roundup of what has been happening.
Name Change: 5x5 has been renamed as Mini-STX.
ASRock have announced a H110M-STX Motherboard and a H110M-STX MINI PC using this motherboard: Tomshardware have specifications.
MSI announced a Cubi 2 Plus barebones based on Mini-STX: PC World have details.
ECS have shown their H110SU-02 Mini-STX board and LIVA ONE and SF100 machines based on Mini-STX : MaximumPC and LegitReviews have your back for these.
Akasa have demonstrated their fanless Euler ST enclosure: : Hexus from FanlessTech this time.
And finally, Silverstone have shown a Mini-STX enclosure of their own: TomsHardware again.
Intel introduce 5x5 boards: Socket CPUs supported up to 65W TDP, Smaller than Mini-ITX, Larger than NUC
September 02, 2015
Intel have introduced a new motherboard form factor targetted at manufacturers of miniature systems which measures approximately 2/3 of the size of 170 x 170mm Mini-ITX boards, with the ability to add up to a 65W TDP socket CPU.
The approximation has spread to the 5x5 name - the boards more accurately measure 140 x 147mm, or 5.5 x 5.8 inches.
We'll let this slide as the 5x5 board shown at IDF 2015 has some interesting features.
The socket itself looks to have a narrow mounting pattern meaning custom heatsink solutions will be required. Intel are pushing manufacturers to use copper to reduce temperatures. The most powerful 65W TDP processors will sit in taller chassis due to the increased cooling requirements.
Much like NUC PCs, chassis designs across manufacturers will share similarities as Intel have strictly defined the position of all components on the boards, with connectors positioned on both the front and the rear. Power is provided by an external AC Adapter.
The example board appears to have a DC input, (HDMI?) Graphics outputs and Ethernet on the rear, with a headphone output and USB on the front of the board. There is a single SATA socket for chassis variants supporting 2.5in HDD or SSDs, together with an M.2 SATA socket for solid state storage mounted directly to the board. The 2x SODIMM slots suggest at least 16GB will be supported.
