Speaking of ALIENWARE, I would think that the brand on Tall has experienced his game console since he went to the store. He feels that the hardware that can smoothly experience the game masterpiece in such a small box is really superior in design. His own old computer was allocated in 2010. At that time, I3cpu+4G memory + GeForce GT240 was available. At that time, it was OK to play, but now it can only be done as a simple office Internet connection and watching movies. The suspended animation and blue screen that had not stopped some time ago made me really want to change my new computer. Originally wanted to wait for the graphics card to be better. The second-generation ALPHA had a good price to start, but the old computer made me crazy to the point that there was a chance that the generation of the ALIENWARE STEAM MACHINE was almost in clearance, and the price was very good. In line with the 10% cash back activity of CCB starting in July, we can get a good price.
Because of the low price of the previous 520 knife price, I began to focus on the price of Meiya. Unfortunately, every time the United States and Asia are about to reach a new low, Aunt Zhang begins to break the news. People see more and orders more. He does not fall. My heart was expected to be about 500 knives. On the day before the PRIME member of AIU, I saw that Aunt Zhang broke the news again, and the price began to rebound. I didn't wait for it, and immediately placed an order. The price of the order was then 529.44, and then July 24. A new low of $518.55 has appeared on the day. As such, the CCB will return 50 knifes, almost 480 knives. I bought a few days, DELL Mall's I5 version as long as 380 knives, and I bought a difference of more than 100 knives, I want to want to buy it, then the price of I5 version is better.
Meiya was delivered to me by the member's day for a long time. I received the order on July 12 and received it on July 22, and all of them had been handed over. The transshipment option is to transship China, because he has always used his family and at least feels safe and reliable. This time to catch up with the G20 summit, once again experienced, the transfer is slow and tax guilty.
The payment was made on July 22, and it was on August 14th. Finally, a tariff of 150 yuan was paid, plus freight of 310 yuan. A total of 4,000 yuan was spent.
Start: I originally thought that the box was quite small, and it was bound to be small. It turned out that I was wrong. How big was this box sent?
Box set of old routines for boxes
Packaging is still good, the alien logo, MADE IN CHINA's products are actually in English and Japanese packaging, there is no Chinese, Japanese is to go to Japan and Dafa competition PS4 it?
Excited to open the box
Handle instructions? This is not an empty study
The opposite is a variety of warranty cards and instructions, no Chinese, too lazy to see
After opening, I finally saw the true colors of my eyes. For such a large size, the handles, the mainframe, and the accessories were placed sideways. If the volume of the handles would not be much smaller, the handle would also be quite large.
Look at the host first
There are two USB2.0 sockets on the front, and there will be a flashing effect when it is turned on. It looks very cool.
Behind is the cooling hole, when the game runs, the fan whine, the cooling effect is not bad. The interface is less, HDMI IN, HDMI OUT, network cable interface, two USB3.0 interfaces. There is no 3.5 audio interface, but fortunately my monitor is ASUS VX239, comes with audio, and my JBL snail audio is also connected via USB, so there is no problem. However, the lack of a USB interface is a big issue for me. General keyboard, mouse, stereo accounted for three interfaces, only one interface can be used, to connect USB devices can only use USB expander.
Forgot to say, in fact, there is a USB interface at the bottom of the machine, but it has already inserted the STEAM controller Bluetooth transmitter ...
Next look at the handle
This handle is really very creative ideas, there are remote sensing button with a touchpad, it looks very big on it, the actual experience Well ... I said later when the game say it. The feel of the handle is not as good as the PS3 handle, but it is decent and the button is also very sensitive. The back of the fashion battery is open, and the design of the buckle on both sides is very good.
Say the next accessory
The power supply is larger than the monitor's power supply and it is also heavy
The power plug is the US version, unless the home is a very old kind of universal tow, otherwise it must use the transfer interface.
HDMI cable, length can be
These are the accessories for the STEAM handle. The purpose is to connect it from a USB port to connect the Bluetooth transmitter of the handle. It seems to me useless.
With the handle and the machine put together, I think the host is really small.
Well, everything has seen it and started to boot. The first boot is the machine settings. The next step is very simple.
Create an account to enter STEAM OS with 6 free games
In addition, you can check the machine configuration in STEAM OS
Show CPU core frequency? The default should not be so high.
Activate the game's interface, if you have bought a game before, enter the code here.
STAEM OS is to play the game, actually let him become a computer or WINDOWS operating system, according to the online tutorial to be a recovery U disk can be restored to the ALPHA system WIN8.1, because now WIN10 is not free upgrade, only Can reload the cracked version of WIN10. In fact, you can also use the U disk to install WIN10, but this way ALIENWARE's software is gone, such as that can adjust the light.
After loading the desktop is very clean, nothing to hide, retaining the ALIENWARE wallpaper, I think although troublesome, but better than directly installed WIN10.
Master Lu runs about
CPU rating is very high, think about it, after all, is the I7 version
Then install the STEAM version of WIN, so that the handle can continue to use, STEAM game can continue to play. There are many free games in STEAM. I also chose to install a free Magic card and slowly study the rules of the game.
Say the experience of using a few days. It is really fast to use, open web pages, documents, PDF, PPT what are all seconds open, and the original host is really worse than the difference. Really benefited from I7 CPU, even friends who helped me install the system said that the machine performance is very good, if you buy the I5 version or did not buy the I7 version. And at the same time, my Thunder Baidu Cloud WeChat web games are open and they are very smooth. If you do not play games, it is really quiet. The game fan reverberates, but it is not very loud and is considered to be acceptable. The whole machine's warranty is 240 days left, I will tangled or not to trouble the transfer of insurance, and each time the first opportunity to start flashing yellow light flash blue light, think of the yellow light door thing, I feel there is a little panic.
But the STEAM controller is really a tasteless product. Under WIN10, he identified him as a keyboard mouse. . . , which means that even WIN does not think he is a gamepad, this problem is also reflected in the PC game. Pirates matchless 3 directly do not recognize the handle, the same I changed the handle of the North pass, the Pirates unparalleled 3 directly recognize. Switch to STEAM software, the handle is actually very coordinated, there are many games to use the touchpad, but always feel no rocker convenience.
This host's graphics card is a GeForce 860M, as long as it is not a problem with the graphics card killer, tested the pirates unparalleled 3, the game screen and PS3 almost. For those who like to play such games, the game performance is enough.
Finally, it concludes: Positioning balance, a desktop host that can both work and play, small and quiet, casually placed on the table, does not take up space, can meet daily game and office needs. Disadvantages: Steam controller tasteless, if only as a game console to go beyond traditional hosts such as the PS4 and XBOX ONE is not yet possible. If you have high requirements on the performance of the game, it is recommended to wait and see it, second-generation graphics card is very high, but the third-generation graphics card will not be higher, the other two generations of people reported high fever, the fan ring. If it is not a particularly high requirement for the game, a high-end version of the generation is definitely a good choice for money.
