If your laptop is not in thel isting, then we can not make sure it can be compatible 100%.

1. Usually the laptop with correct interface can work with our products , but some laptops can not work with it because different design or configuration. Not all model of laptop support to use this product. You need to learn it fully before buy it.
2. Some laptop has both 2 of the interface , but it just support to use one of interface to connect external graphic card. For example the Lenovo T420 , it can use Expresscard interface to use this product , but can not used on wireless card interface (NGFF M.2A Key ).
3. Some old model laptops must use 1 piece of 2GB RAM memory-chip to use this product. Especially the laptop use the mainboard before HM65 ( less laptops model use mainboard after HM65 also need to use 1 piece of 2GB RAM memory-chip )
4. If your laptop do not support connect to the external graphic card by EXP GDC , or you choose the wrong interface cable for your laptop , we can not refund the money of product. But we provide the goods return & money refund in this situation ( the condition of product don't affect secondary sale )

5.When use the ngff m.2 a/e key , some laptop may have the white list problem. Because these laptops may not be connected to the M. 2 A/E key using products other than those specified by the manufacturer. To solve this problem, you need to learn to whitewash BIOS. BUT whitewash BIOS has high risk for your laptop. If you are not good for it, please do not do it.

About Graphics Card :
1. The list of recommended graphics card:
GTX650 GTX660 GTX670 GTX750 GTX760 GTX950
GTX960 GTX970 GTX980 GTX1060 GTX1070 GTX1080
And for other graphics cards, may be they can also be used, but the compatibility and performance are not as good as the cards in list.
2. For GTX 1060 1070 1080
They are compatible with EXP GDC, but you must install the Auguest 2016 driver(372.70 version). And GTX 1080 is the most powerful we Recommend.

My laptop is xxx model, does it work?

If you are laptop model is in the support listing, then usually it can work. If it is not in the support listing, then we can not make sure it can work 100%. If your laptop is in the listing that not support, then do not buy it.

Which interface is my laptop use ?

You can take some clearly photo of the interface of your laptop has and show to us. Except for the expresscard interface, you need to open the back of the notebook to look at it.

What power supply should I use for it ?

We suggest the ATX power. The power need to be enough for your external graphic card. For expample, if your exernal graohic card use 300W power, then you had better use a 350W ATX power.
Please connect the power cable correct. ( we have the picture to show it in the product description)

Can I use the DC port to supply power?

Please note that the DC port for power input allow 12V power, the currect can not be over 12.5A. So it can only supply 150W power. And you can only use the external graphic card that use power no more than 150W. Also make sure you use a good quality power supply, otherwise it can damaged your devices. Connect the power cable by wrong method can also damaged the devices. DO NOT supply power before you connection is well.

Annah L
Quality product arrived well packed. Content matches description. After I test I will comment more. Ordered 2020-10-22 and arrived December 2nd in Bulgaria with Ali Express shipping

First I thought my laptop has mini pci (Toshiba S55T-B5273NR) but I disovered laptop has NGFF port so I ordered another cable. I installed Nvidia GTX 1050 TI and got the error 43 but fixed by applying registry fix and I got the graphic card working perfect.

Almarie H
Perfect and faster I don't know can ask! Connected to a GTX750ti with a 400w source, all working OK

Alvesta C
The product arrived in 30 days quite a while to my mind but very well packed and without any problem I would recommend seller

Alzena H
I took the ExpressCard version.
On the laptop Fujitsu Lifebook A512 did not exist. Vidyaha gtx960.
The laptop turns on only without an adapter, and only then, to Windows stuck eGPU. Then windows sees vidyahu, firewood gets up, but error 12. The solution to this problem is (DIY eGPU setup 1.3), did not help... Spent 4 pm. Tried everything.
All right, guys, I don't care about him. Go to the "Iron" (Shop B. U. Components) and buy there Mother + percent (i5 2400)+ Opera (8 GB) + BP for 10 thousand With 1 month warranty. And screw at home find and do not waste your time.
What I wrote all this to: I read and saw how others work. If anything, I'm a programmer, and tried everything with the dsdt file, windows is worn out if something is wrong and is going to be reinstalled. On the firmware left bios did not decide, there was not enough laptop to use. Tried on Ubuntu-also not.
The delay on the adapter (7 or 15 seconds) does not work-supplied power, immediately turns on.
It is worth taking only if there is 100% INFA, which on your laptop works out of the box.

Aminta N
Unfortunately, it does not work on my notebook, when I reduce the amount of RAM to 2GB it works, unfortunately at 8GB it does not work.
Well packed, the parcel arrived very quickly.

Alzora G
I arrive in the expected time all very well

Annemarie J
Very well described according to what is said in the ad. The product arrived in perfect condition and extremely well packed. Still will test when the board! But until then 5 stars. Arrived in Brazil in almost 3 weeks on Christmas! Fast delivery.

Alvernia N
Received in perfect condition, the driver configuration process in my case was quite tedious due to a conflict that had the 1050ti (External) with 960m (internal) but in the end, playing here and there, I get to set it up and it turns out to be a pretty positive change.
