Features
- FAST, FLEXIBLE, FUNCTIONAL - All members of the ROG Flow laptop family have a secret weapon the XG Mobile. ROGs exclusive XG Mobile ecosystem of external GPUs provide amped-up horsepower and offer a built in I/O hub, allowing higher bandwidth to Flow devices with a proprietary PCIe connection. The XG Mobile features an NVIDIA GeForce RTX 4090 Laptop GPU with a max TGP of 150W, allowing you to transform your Flow device from a mobile gaming laptop to a true battlestation.
- I/O EXPANSION The XG Mobile is more than just an external GPU. Thanks to the plentiful bandwidth provided by a PCIe Gen3x8 connection, it also serves as an I/O expansion hub. HDMI 2.1, DisplayPort 1.4, 4 USB 3.2 Gen2 (1 of which is Type-C), an SD card reader, and a 2.5G ethernet port make any XG Mobile-connected Flow device a true battlestation with one cable. It also delivers power directly to your Flow machine with an integrated 330W power adapter. With the XG Mobile, you can leave your dongles at home
- NEXT LEVEL COOLING Despite being the size of a hardcover novel, the XG mobile brings plenty of firepower to the party. The XG Mobile needs to stay cool without compromising acoustics during extended play sessions, so we leveraged our Intelligent Cooling tech to keep this external GPU cool and quite. Featuring a vapor chamber on the GPU die, the XG Mobile can provide up to 150W of power to the GPU without breaking a sweat.
- Only compatible with rog flow and ally

I use this with 1st gen ROG Ally. It’s amazing, I believe this will be the future of gaming.

Picked it up for my ROG Ally Z1 Extreme since I've been using it docked as a PC I could take with me. These are hard to find in general so when there was a 4000 series I had to get it. Have only had it for a couple weeks but my thoughts are below. Installation is relatively simple you just need to ensure the connection is SNUG and locks into place. Initial setup the unit would not power on and the RGB fan light didn't illuminate so I was afraid of a bricked unit. But the good old unplug and replug fixed that issue. I do wish the cable to dock your device was a bit longer. Once the device was powered and connected you have to click the XG Mobile icon in the system tray. What's annoying is that the icon FREQUENTLY dissappears. Literally as I am writing this review the icon is missing. Not a problem if you keep your device docked but since I have an ROG Ally, the expectation that I would frequently take the device with me on the go is there. I have not encountered any other issues with the device apart from those mentioned in this review. The fan ramps up when gaming but it is not as loud as I was expecting it to be. The sound level is noticable in a quiet environment but not a problem if you play audio through speakers or use headphones. Haven't tried super intense games but it works very well for what I want to play. Overall if the process of connecting and disconnecting the XG mobile and the cable were a little longer this would be a 5 star review.

I know nothing about the flow products that use this as well, but its so much fun on the rog ally. The perfect handheld hybrid pc now. Comes equipped with raw power. Most external gpu only take advantage of about 70% of the gpu but with asus you get about 90% with little to no bottleneck. So easy to set up, make sure the ally is up to date then plug the xg up and you have an update that will make you restart and away you go. Anything of this nature is no expensive so you are not saving much money depending on your needs. Becuase to take full advantage you will need a monitor or tv that takes advantage of all that power. The gpu can get load but it stays relatively cool. It's alot cooler than my asus zephyrus g14 ryzen 9 3060 I will tell you that. The Cord is short and you have to bend it a little, I set the gpu up a little higher so I don't have to bend it at the connector end of either poi t of the cable to pro long it. The cable is thick so I trust it. Gives me just enough ports to plug everything in as I like wires and prefer to have as little lag as possible. With the current discount it's so worth it. No longer in production so if you had it on your mind I say do it but I'm an enabler 😁. The stand on the gpu is surprisingly sturdy and can hold up with all my cable tugging on it every way. Still playing with it but first couple hrs of gaming are amazing.

Had it for about two weeks. Was super excited and worked decent for a day or two without issues. Benchmarks were great and all happy. Spent my last week and a half trying to get the damn thing to work now. Keeps making my x13 go to Blue Screen of death. With constant reboot s. Now, display port isn’t working . But it worked great for a week. Every time I try to update nvidia driver it goes to BSOD. Other issue is you are supposed to got to your windows tray and clock the xg mobile icon to disconnect. Damn icon doesn’t work. I really love my flow x13 but want more power at home. But this not working may be the deal breakers.

I don’t write a ton of reviews but I had to share this with my fellow gamers! Diehard PlayStation/COD-BO6 fan. Looking for a mobile solution to play on the road I got a ROG Flow Z13 (2021) only to find out it could not quite hang with the graphics. Found this USED XG Mobile for $500 off and took what I knew was a big risk, but hoped I could return to Amazon if defective. It arrived and BOOM. Perfection. The screen on my Z13 is gorgeous after a few clicks. Plug/update/play and be amazed. There is actual blur of scenery in the distance as you start to stare down your scope for a shot. Playing Black Ops now is like watching a movie at the theater. And my game has improved! Put it up on the Samsung 55” and I am telling you it beats out my PS5! Picture is gorgeous, no lag/snap movements and with the clarity so many long shots!!! I am seriously considering moving completely to gaming off the Z13 with this 4090 (laptop) cranking! Amazing I feel like I’ve won the lottery here. Now back to gaming ;-)! Oh yea Forza Horizons wow - I’ll let you be surprised by that one yourself, it is a treat!

If buying used make sure you take into account the serial number will already have been used for the warranty most likely. Otherwise I got one and it's an amazing product I use for my ROG Ally z1 Extreme. I upgraded to this and now use it like a desktop with a 34 inch curved monitor and it's the best gaming I've done in ages! It runs literally anything amd everything with zero issues.

Not disappointed with what I got so far, They need to change the listing from "24gb vram" to 16gbvram. Also highly suggest with going with used very good, being frugle with item like this is the best way to go, I would rather pay 1700 dollars (plus tax) and run the possibilities of defects and deal with Amazon's return policy to get another one, than paying 2k for this. Functionality is already tremendous. If you're looking for something silent wouldn't advise this however its the only thing on the market I've found thats useful, the XGM is silent itself but your computer will sound decently loud.
