Pros: -first of most importantly, it works great with 9800x3d -In general very quality board, feel very solid -Like the design, good looking in my opinion -USB slots are plenty and they marked with the speed! Very detailed work. This board is one of the few that marked the port with speed. Good job! -plenty of space for M2 SSD. (you have to be careful though when using them) -EZ release button is expected for this MB at this price -Some promotion to cut down the price a bit -I like the bios, easy to navigate the use -Very good customer service for rebates/promotion redemptions, which makes me thing the customer support for the product should be good (have not used it since it was working perfectly)

Cons: -Ok, customers have to make sure you read the manual before you using the M2 slot, because the M2_2 is sharing lane with the GPU in PCI_E1. The design would be better if the M2 slot was not sharing lane with the GPU. Asrock Nova and Taichi can do up to 5 M2 slot without sharing lanes with GPU, with a lower price... -No back plate for a MB of $500. Asrock Nova has the back plate for cheaper MSRP...Come on MSI -Would be nice to have a 10G port for internet.

Overall Review: So, my use case is to find a mb to pair with my newly build 9800x3d + 4090. Background is that I like MSI products, as my last board is Z270 gaming pro carbon. In general, this MSI X870e carbon is a great board, is significantly better than Asus X870e Hero and Gigabyte X870E Aorus. However, overall features and the price of this motherboard makes me feel it's really hard to win out when compared with Asrock X870e Nova and Taichi. The design has some flaws in my opinion in terms of M2 SSD slot, and lack of back plate. It just could have been better made. I picked the MSI eventually due to the look, bios, and brand (service), availability, and also due to a couple of promotion to make it more competitive. I still recommend this since it is working great! However, maybe I was picky as a MSI fan, by taking one point off, I just hope MSI could make this board better so that I don't have to debate so much to pick this one over other competitions.

Pros: It is so fast. Upgraded from my old Corsair Force 120G. Very obvious upgrade in speed. In addition, the samsung has a very good software support for the new 840 EVO. Very love it!!! You must buy Samsung if you are going to have a SSD!!

Cons: A tiny expensive

Overall Review: Hope Samsung can continue to do a better job in the software support

Pros: Thanks, Newegg and rosewill, both of them help me out and gave me full refund and covered returning shipping. Great service!! Love it.

Cons: Thinking to get another case to make sure your video card can be used

Pros: Corsair finally created a RMA for me and exchange a brand new one for me for free! Love it!!

Cons: None
