The last time was “VAIO S15 ALL BLACK EDITION” equipped with Core i9-9980HK, the last time was “VELUGA 5000 / ELVLG5K93221TB24K3WR” equipped with Core i9-9880H and Quadro RTX 5000 with Max-Q Design followed by high-end notebook PC But this time I would like to introduce a high-end desktop PC with Core i9-9900K and Quadro P2000.

When you hear that the top processor of the K model number at the end of the SKU and Quadro is installed, it sounds like a full tower type with loud and noisy sounds, but this machine adopts a water-cooled CPU cooler of 25.5dB at idle and 32dB at high load, With a power supply externally attached, it has a 176 x 176 x 365mm (width x depth x height) and a fairly compact, cylindrical design. The main specifications are as follows.

Asus Mini PC Specification Details

The network is Gigabit Ethernet for wired LAN and IEEE 802.11ac for wireless LAN. Built-in Bluetooth 5.0. Other interfaces are Thunderbolt 3 × 2, USB 3.1 × 4, audio input/output. Simple yet powerful configuration.

The power supply is 180 + 230W. I thought at first, but as you can see from the photos, the package contained two 180W and 230W AC adapters. Of course, both need to be connected to the main unit.

The size of the case is 176 x 176 x 365mm (width x depth x height). The housing form is cylindrical as you can see. The top of the case is equipped with illumination that changes color. Weight is 5.2kg. The price is an open price, but I looked at the price. Is it a reasonable place considering the composition?

In addition, “PA90-M9112ZN” which changed dGPU to GeForce RTX 2060 on November 6th is announced. Will this be a gaming Asus Mini PC due to the characteristics of the GPU?


The case is cylindrical and all black. The front is flat but many others are slits. The top lid is removed at the time of packing and will be installed later. When the power is turned off, it is closed without any gaps, but when the power is turned on, it automatically rises and there is a little gap, and you can see the illumination from there.

The lid and illumination are designed to change the gap height and color depending on the CPU load. It is interesting as a gimmick, but unlike a gaming PC, it will not be noticed by those who use workstations.

Asus Mini Power to PC

Size 176 x 176 x 365 mm (same) is the smallest class ATX compatible case used in making a self-made PC with i5-6600 in 2015, compared to the desktop PC on hand (size RANA2) ( 154 × 465 × 367mm / currently out of print). And the height is almost the same. There is no half depth. I’m honestly surprised that Core i9 and Quadro are housed in the case.

The power button on the front, USB 3.1 × 2, microphone input, headphone output. There is no expansion slot on the back, antenna terminal for Wi-Fi, DisplayPort × 4, headphone output, USB 3.1 × 2, Thunderbolt 3 × 2, Ethernet, CMOS Clear, power input × 2. Although there is no expandability using the old expansion slot, there is no problem in practical use as long as the latest ports are available. The power input is for 180W on the left side and for 230W on the right side.


The included AC adapter is a 230W type with a size of about 160 x 75 x 30mm (same), weight 630g, and output 19.5V / 11.8A. 180W type is approximately 157 x 75 x 25mm (same), weight 511g, output 19.5V / 9.23A. The shape of the AC plug is different. I’ve reviewed many PCs so far, but this is the first time I have two AC adapters. Whether it is to make the case compact (or is it maintainable), if there are two AC adapters that are so large, it is quite bulky.

I’d like to disassemble and check what the inside looks like, but unfortunately, I didn’t see it because it’s not easy to remove. The company’s website also includes a picture of the internal structure, so if you are interested, please see it.

Although this type of workstation has power, there is an image that the sound is noisy, but this machine employs a water-cooled CPU cooler, 25.5dB at idle and 32dB at maximum, very quiet. Also, almost no air from the fans. You will not be bothered by putting it on the top of the desk (that is, the ears are close). A workstation that can be used in a quiet office without worrying about the surroundings.
