MSI Katana 15 HX B14W Review (2026): Upgradeable Value

If you want a gaming laptop that can handle modern games at 1080p and 1440p without moving into the premium end of the market, this MSI Katana 15 HX B14W review is aimed at you. The Katana 15 HX sits in the mid-range part of the market. It combines up to an Intel Core i9-14900HX with up to an NVIDIA GeForce RTX 5070 Laptop GPU, and it leaves the RAM and SSD easy to expand later. It suits budget-minded gamers who want upgradeable 1440p performance. This review is based on MSI's manufacturer specs and on what independent expert reviews report, not on hands-on testing.

MSI Katana 15 HX B14W review: design and build

The Katana 15 HX is a 15.6-inch gaming laptop that measures 359 x 262 x 25.5 mm and weighs 2.4 kg. That is portable enough to move between a desk and a backpack, but it is not a thin-and-light machine. Think of it as a desktop replacement that can travel when it has to, with a 240W adapter to carry along.

Reviewers describe the design as sturdy and understated. That matters if you want a gaming laptop that doesn't look out of place in a classroom or office. The keyboard has four-zone RGB lighting, highlighted WASD keys and a number pad. The number pad is a practical bonus for spreadsheets and for games that use many keybinds.

The port selection covers most needs:

• 1x RJ45 for wired Gb LAN
• 1x Type-C (USB3.2 Gen2, DisplayPort and PD 3.0)
• 3x Type-A USB3.2 Gen2
• 1x HDMI 2.1

Reviewers single this out as a strength. Wired networking and HDMI 2.1 suit a desk setup with an external monitor. The Type-C port with DisplayPort gives you another way to connect a screen.

Display: QHD 165Hz, with a catch

The headline display is a 15.6" QHD (2560x1440) IPS-level panel running at 165Hz, with 100% DCI-P3 (typical). A 144Hz FHD (1920x1080) option is also offered. The QHD panel is the more interesting of the two, since the GPU range is pitched at 1080p and 1440p gaming. A high refresh rate is useful for fast shooters and competitive games, and the wide colour coverage on paper is a nice extra for casual creative work.

The display is also a common criticism among reviewers. A common criticism is that the screen can look dim and washed out, so you will probably want to raise the brightness. The spec sheet lists the colour gamut and refresh rate but gives no brightness figure, so don't assume the panel will stand up to a sunny room. If you mostly play in a dim bedroom or at a desk, this matters less. If you game near windows, take it seriously.

Features and what they mean day to day

MUX switch

The MUX switch lets the discrete GPU drive the display directly. In practice that means the graphics card sends frames to the screen without routing through the integrated graphics, which is how you get the most out of the GPU in games. Reviewers specifically praise this feature on the Katana 15 HX. It is a useful sign that MSI built this laptop with gaming performance in mind.

Cooler Boost 5

MSI uses its Cooler Boost 5 cooling design to keep the high-power components in check. It has a real job to do. The GPU can draw up to 115W maximum graphics power with Dynamic Boost, and the CPU can reach up to 24 cores and a 5.8 GHz max turbo. Reviewers note that the cooling comes with trade-offs: fan noise and a warm keyboard under heavy load are common criticisms. If you play with headphones, the noise matters less. If you hate fan noise or plan to use the laptop in a quiet room, keep this in mind.

Upgradeability

This is one of the strongest reasons to consider the laptop. It has two DDR5-5600 memory slots that accept up to 96GB in total, plus an M.2 NVMe PCIe Gen4 SSD slot. You can buy a configuration that fits your budget now and add RAM later as needs change.

The storage side has a limit. There is only one M.2 slot, and the configurations come with 512GB or 1TB. Reviewers point out that the 512GB base storage fills quickly. To get more space you will be replacing the drive rather than adding a second one, so factor that into your plans.

Connectivity

Wireless is handled by Wi-Fi 6E and Bluetooth 5.3, which is a sensible match for a gaming machine. Combined with the Gb LAN port, you have good options for low-latency online play.

Audio and webcam

The laptop has 2x 2W speakers and an HD webcam (30fps@720p). The spec sheet doesn't go beyond those figures, so treat the speakers and camera as basic extras rather than selling points.

Performance: what the hardware suggests

The range goes up to an Intel Core i9-14900HX and up to an RTX 5070 Laptop GPU with 8GB GDDR7, so check exactly which CPU and GPU the listing you are buying includes. The GPU is positioned for 1080p and 1440p gaming, and reviewers praise the laptop's gaming performance for the price. That fits the QHD screen well, though native QHD gaming will ask more of the GPU than FHD.

The GPU has a maximum graphics power of 115W with Dynamic Boost. Reviewers also mention heat and fan noise under heavy load. More performance in a 25.5 mm thick chassis comes with thermal consequences.

Battery life

The battery is a 4-cell, 75Whr unit, which sounds generous on paper. Reviewers nevertheless criticise the battery life as short, and that is the usual story with a high-power gaming laptop. Treat it as a machine you game on while plugged into the 240W adapter. Reviewers criticise the battery life as short, so don't count on all-day use away from a socket.

What experts like and what they criticise

The independent verdict is positive. The laptop averages 8/10 across 2 expert reviews. Tom's Hardware gives it 4/5, and Tom's Guide's score is listed as 80/100 by Notebookcheck.

Reviewers consistently praise:

• Strong 1080p and 1440p gaming performance for the price
• The MUX switch
• The upgrade options for RAM and storage
• The port selection, including HDMI 2.1, USB-C with PD and Gb LAN
• The four-zone RGB keyboard and sturdy design

A common criticism is:

• A display that can look dim and washed out
• Short battery life despite the 75Whr cell
• Fan noise and a warm keyboard under heavy load
• Only one M.2 slot, with a 512GB base storage that fills quickly

The pattern is clear: reviewers praise the gaming performance and upgradeability, while the display, battery life and fan noise draw the criticism.

Who should buy it, and who should skip it

Buy it if you want a gaming laptop that delivers strong 1080p and 1440p performance without a premium price. It also suits you if you like the idea of adding RAM or swapping in a bigger SSD later, or if you want wired networking and HDMI 2.1 for a desk setup. If you game mostly plugged in and with headphones on, its weaknesses will bother you less.

Skip it if you need a bright, vibrant screen, long battery life or a quiet machine under load. Reviewers commonly criticise the dim display, short battery life and fan noise under load. If you rarely move your system and care more about cooling and future upgrades, a desktop may suit you better. Our guide to the best prebuilt gaming PCs covers that route.

How it fits in the gaming laptop category

In general terms, gaming laptops make you choose between performance, portability and cost. The Katana 15 HX leans toward performance and value. It gives you a high-power GPU, a high-refresh QHD screen and upgrade slots, and it accepts compromises in battery life, noise and display quality. It is not a slim, quiet, all-day laptop, and it doesn't try to be one. If you understand that trade-off, the feature set is well matched to the price tier.

Verdict

The MSI Katana 15 HX B14W is a practical choice for gamers who care about frame rates and flexibility more than polish. Strong gaming performance, a MUX switch, a QHD 165Hz option, a good port selection and room to expand memory and storage make a persuasive package. The dim display, short battery life, fan noise and single M.2 slot keep it from being an easy recommendation for everyone. Check which CPU, GPU, screen and storage configuration you are buying, then decide whether you can live with the downsides. If you can, it is a solid, upgradeable pick for 1080p and 1440p gaming.
