    • Good enough.
CPU: Ryzen 9 RAM Size: 64 GB Hard Disk Size: 2 TB Graphics Description: RTX 4070 Style: 17" QHD+
Got it cheaper than Newegg, does everything I want it to do. Kinda wish the keyboard was individually RBG instead of zone RBG. But it’s great otherwise. Minor negatives, can get a little warm, use a cooling pad if gaming. Battery life is okay when NOT gaming. HD video or gaming will kill the battery in an hour. Battery will drain faster than it charges when gaming. Take occasional little breaks if you plan on marathon gaming. ... show more

    • Good laptop.
CPU: Ryzen 9 RAM Size: 64 GB Hard Disk Size: 2 TB Graphics Description: RTX 4070 Style: 17" QHD+
Good laptop. I bought the maxed out version with 64 gb of ram, a Ryzen 9, and a RTX4070 Very good components and parts. After 8 months of service I have not had any issues with hardware. I had to update the bios to fix some bugs that it came in out of the box but that was not a big deal. Materials are OK. A lot of plastic. It has a very good cooling system. Don’t expect a quiet laptop while gaming with this one. It performs very well. It runs tarkov in 2k at 70fps in streets. ... show more

Review Image by John Bang
So far a great laptop. It's lighter and more powerful than my old Acer Predator and generates half the heat. The keyboard function keys are weird to get used to but you get used to it. The sleep function...this laptop does not like sleeping. It randomly wakes up for no reason lol Gaming, this laptop does what I bought it to do, and does it well. Again, with less heat than my previous laptops. The ports are all stiff and solid, which you want. USBs dont wiggle at all and dont randomly fall out. The buttons feel great to press, soothing for my autism. The wifi adapter on here is really strong, way stronger than my old laptop. The 4070 and Ryzen 9 combo are fantastic for pretty and intense games like Helldivers. NOTE: if you have trouble with the built in crosshair (which is usefull tbh), then go to the settings for it and disable the option allowing you to move it with cursor. Works wonders so your game stops switching to desktop. ... show more

Great laptop specs are crazy for the price. Still use it to this day for everything. If you got the money why not.

    • Battery is not the best
CPU: Ryzen 9 RAM Size: 64 GB Hard Disk Size: 2 TB Graphics Description: RTX 4070 Style: 17" QHD+
Performance is fantastic. Battery Life is surprisingly low. I expect it would not be the best, but this thing just being at the home screen with base installed programs running needs to be charged after about 45 minutes. I just ran a stream on it to see how long it lasts with one browser open, and it was about 36 minutes. ... show more

    • Why I have missing parts ??
CPU: Ryzen 9 RAM Size: 64 GB Hard Disk Size: 2 TB Graphics Description: RTX 4070 Style: 17" QHD+
I bought this laptop 8 month ago and first problem I run into when I just unpacked it. I push the power button the screen show me MSI dragon logo and nothing more 😆(laptop battery was full charged) okay this problem easily solved by update BIOS. And what are people doing when they unpacked brand new gaming laptop ?? Right I download my favorite game and start it with ultra high resolution. My laptop works lesser then minute and just switch off. I start it again and repeat, same pattern happens again and again. After 15 minutes of research I noticed then my laptop just overheated and system just shut down computer for protection. I start Google it and find a lot of reviews about gaming laptops and overheating, most of them tell me it is normal, because laptop is small and difficult to cool it fast. Next months I just use it and some times it happens again, but last month my laptop shut down twice per day even I didn’t use it “hard” and I done deeper research. A lot of people suggest changing thermo paste, cause manufacturers just saving money and use cheaper products. Before I made a decision opening my laptop a think a lot because I still have warranty and don’t wanna lose it. But my laptop going overheat each day more and more. I want to say, before u opened it seal was good. I don’t know it is manufactured seal or somebody fake it but it was on the place. When I opens back panel I was shocked 4 screws from CPU cooling system was missing. I removed cooling system and what I see was terrible. GPU and CPU dont cover of thermopaste. I cover it with paste and put it back together with 4 more screws which were absent. I run my laptop with high resolution games now and temperature stay good all time no more protection shutdown. I want to say to sellers and manufacturers how are doing guys ?? The product work perfect if it have all parts inside, but why I received laptop with 4 lost screws and no any trace of thermopaste covered my processor units???? Now after 8 month of using device I can start have 100% quality. Device is good with correct assembled cooling system but I give 1 star for all the problem what I have. ... show more

    • Awesome laptop.
CPU: Ryzen 9 RAM Size: 64 GB Hard Disk Size: 2 TB Graphics Description: RTX 4070 Style: 17" QHD+
I am doing this review on my new laptop! This thing works great, it starts right up faster than any other laptop I've ever had. It runs all my games on full and doesn't crash. I had another msi laptop before that lasted seven years before it started to slow down a bit, and decided that I would get another msi. This thing is great it is not loud and is very easy to set up. I play a lot of video games and this is awesome. ... show more
