The MSI Katana 15 is a value-focused gaming laptop delivering solid performance via 12th/13th Gen Intel processors, RTX 4050/4060 graphics, 15.6″ FHD 144Hz display, and surprisingly—dual DDR5 SO-DIMM slots supporting up to 64GB RAM. While it features only a single M.2 NVMe slot and a modest 120–150W charger, the Katana 15 punches above its price point for RAM upgradability. This guide covers complete MSI Katana 15 compatibility for upgrades.
RAM Compatibility for MSI Katana 15
The Katana 15 is a budget gaming laptop with a pro-level RAM upgrade path: two DDR5 SO-DIMM slots supporting up to 64GB maximum capacity. This is exceptional for the price tier.
Stock Configuration: 2×8GB DDR5-5600MHz (16GB total)
Maximum Capacity: 64GB (2×32GB DDR5-5600MHz)
Supported Speed: DDR5-5600MHz (JEDEC standard)
| Upgrade Path | Configuration | Total Capacity | Best For |
|---|---|---|---|
| Factory stock | 2×8GB DDR5-5600 | 16GB | Light gaming + esports titles |
| Budget upgrade | 2×16GB DDR5-5600 | 32GB | AAA gaming + streaming |
| Professional tier | 2×32GB DDR5-5600 | 64GB | Gaming + heavy multitasking + content creation |
For budget gamers, 16GB from factory is acceptable for most 2024–2026 titles at FHD resolution. However, the RTX 4050/4060 can benefit from 32GB when combined with Chrome tabs, Discord, OBS streaming, and the game running simultaneously. 64GB is future-proofing for content creators who also game, or streamers planning to keep this laptop for 3+ years. To upgrade: power down, remove bottom panel, push retaining clips on SO-DIMM slots, insert new modules at 45°, and press down until clips engage.

SSD & Storage Upgrades
The Katana 15 includes a single M.2 2280 PCIe Gen 4 NVMe slot. This is the only storage expansion option—no second SSD slot is available.
Stock Configuration: 512GB PCIe Gen 4 2280 NVMe (sometimes 256GB in budget configs)
Maximum Capacity: 2TB or larger (cost/availability limited)
Interface: M.2 2280, NVMe over PCIe Gen 4
Performance: 7,000–7,400MB/s read speeds
| Upgrade Option | Replacement SSD | Total Storage | Best For |
|---|---|---|---|
| Keep factory | 512GB (keep) | 512GB | Light gamers, use external USB SSD for library |
| Budget upgrade | 1TB replacement | 1TB | Most gamers, fits 8–10 AAA titles |
| Premium upgrade | 2TB replacement | 2TB | Collectors, store full game library on-device |
For gaming, 512GB becomes tight quickly—modern AAA games are 80–150GB each, so a full library requires external USB storage. Upgrading to 1TB gives you 4–5 large titles installed simultaneously. 2TB is comfortable for gamers who prefer local storage. Installation is simple: power down, remove bottom panel, insert new SSD at 30°, press down, and secure with the mounting screw.

Charger & Power Compatibility
The Katana 15 uses a compact 120W or 150W barrel charger depending on GPU variant (RTX 4050 = 120W, RTX 4060 = 150W). Both are modest by gaming laptop standards.
Stock Charger: 120W or 150W barrel connector (proprietary MSI, depends on GPU)
USB-C Power Delivery Support: No
Peak Power Draw: 110–140W sustained (CPU + RTX 4050/4060 under full load)
| Model Variant | Charger Wattage | Charging Speed | Peak Load |
|---|---|---|---|
| RTX 4050 variant | 120W barrel | 2–2.5 hours to full | ~110W sustained |
| RTX 4060 variant | 150W barrel | 1.5–2 hours to full | ~140W sustained |
The Katana 15’s modest charger reflects its budget positioning. There’s no USB-C Power Delivery fallback, so you’re locked to the native barrel charger for charging. The 120W/150W capacity is adequate for gaming at normal FPS (not max settings) while charging slowly, or playing less demanding titles while charging normally. For heavy gaming and rendering, plug in and wait—don’t expect rapid charge-while-playing performance.

Dock & Hub Compatibility
The Katana 15 includes two USB-C 3.2 Gen 2 ports (no Thunderbolt) and standard USB-A ports. Docking options are limited but adequate for basic connectivity.
Thunderbolt 4 Support: No
USB-C Power Delivery Support: No
Recommended Dock Type: USB-C multiport hub for portable use; external USB SSD for game storage
| Dock Configuration | Connection Type | Use Case | Notes |
|---|---|---|---|
| USB-C multiport hub | USB-C 3.2 Gen 2 | Portable office + casual gaming | USB speeds (1.2Gbps), no power delivery |
| External USB SSD | USB 3.2 Gen 2 or USB-A 3.2 | Game library expansion | Works but slower than internal SSD |
| USB dock (basic) | USB-A | Keyboard + mouse + peripherals | For stationary desk use |
The Katana 15’s lack of Thunderbolt and USB Power Delivery means desktop docking is basic—suitable for peripherals and external storage, but not for professional workflows requiring Thunderbolt bandwidth or power delivery. For gamers, a simple USB hub covering keyboard/mouse/headset is sufficient.

Frequently Asked Questions
Is 16GB RAM enough for gaming on the Katana 15?
16GB is acceptable for most 2024–2026 games at FHD resolution, but tight for multitasking—game + Discord + OBS streaming + Chrome. Upgrading to 32GB costs £40–60 and is recommended for competitive gamers or content creators who also game.
Will upgrading RAM void the warranty?
No. MSI allows user RAM and SSD upgrades without voiding warranty. Removing and reinstalling the bottom panel is a standard service procedure, not warranty-voiding.
Is 512GB storage enough for gaming?
No, not for modern gaming. An 80–150GB AAA game fills half the drive. Upgrade to 1TB immediately (£40–50) or use an external USB SSD for game storage (slower load times but works). 2TB is ideal for collectors who want all games installed.
Can I use the Katana 15 for content creation?
Light content creation—photo editing, YouTube 1080p editing, basic 3D work. The RTX 4050/4060 and FHD display are limiting for serious 4K video or 3D rendering. For hobbyist creators, it’s capable; for professionals, upgrade to a Creator Z16 HX or similar workstation.
Why doesn’t the Katana 15 support USB-C Power Delivery?
Budget constraint. USB Power Delivery support requires specific power management circuits and higher-quality USB-C connectors. At the Katana 15’s price point, MSI saves cost by using a simple barrel connector. USB PD is reserved for higher-tier models (Stealth, Creator, Raider).
