ASUS spans the full range from budget VivoBooks to premium ZenBooks to high-end ROG gaming machines. The upgrade picture is a mixed bag: ASUS’s gaming and business laptops offer excellent upgradeability, while their ultrabooks have moved almost entirely to soldered components.
This guide covers every current ASUS laptop series with confirmed RAM type, SSD compatibility, charger specifications, and recommended upgrade parts for 2026.

ASUS ZenBook Series — Upgrade Guide
The ZenBook is ASUS’s premium ultrabook range. All current models — including the ZenBook 14, ZenBook S14, and ZenBook S16 — use soldered LPDDR5X memory. RAM cannot be upgraded after purchase.
The SSD is typically a single M.2 NVMe Gen 4 slot, though the form factor may vary by model. Most ZenBooks support Thunderbolt 4, and all use 65W USB-C PD charging.
Buying advice: If you’re considering a ZenBook, order with at least 16GB RAM — 8GB is increasingly insufficient for 2026 workloads, and you can’t add more later. See our guide on 8GB in 2026.
ASUS VivoBook Series — Upgrade Guide
The VivoBook is ASUS’s budget range with surprisingly decent upgradeability on many models. Most VivoBooks still use DDR4 SO-DIMM (ASUS’s budget line has been slower to transition to DDR5), with one or two user-accessible slots.
SSD slots are typically M.2 2280 NVMe, though some budget models may have a second 2.5″ SATA bay. Charger type varies — newer VivoBooks use USB-C PD, but some still ship with barrel plug chargers.
Key warning: Check your specific VivoBook model number carefully. The VivoBook range is enormous and specs vary significantly between configurations. What’s true for a VivoBook 15 X1504 may be completely different from a VivoBook 15 M1502.

ASUS ROG Zephyrus Series — Upgrade Guide
The ROG Zephyrus G14 and G16 are ASUS’s premium thin gaming laptops. They use a hybrid memory configuration: one module is soldered to the motherboard (typically 16GB) and one SO-DIMM slot is user-accessible.
This means you can upgrade to a maximum of about 48GB (16GB soldered + 32GB SO-DIMM), but you lose the benefit of matched dual-channel memory if the soldered and socketed modules are different sizes. For best performance, match the SO-DIMM to the soldered amount (e.g., add a 16GB stick to match the 16GB soldered for 32GB dual-channel).
Both models have two M.2 NVMe SSD slots, 100W USB-C PD charging, and Thunderbolt 4 ports.
ASUS ROG Strix Series — Upgrade Guide
The ROG Strix G16, G18, and SCAR models are the most upgradeable gaming laptops ASUS makes. Unlike the Zephyrus, these have two full DDR5 SO-DIMM slots — no soldered memory — supporting up to 64GB. They also have two M.2 NVMe SSD slots.
The SCAR 16/18 (2025) supports PCIe Gen 5 NVMe in one of the two M.2 slots, making it one of the first gaming laptops to offer Gen 5 SSD speeds. The Strix G16/G18 uses Gen 4.
Charging is via USB-C PD at 100–150W. All models include Thunderbolt 4.

ASUS TUF Gaming Series — Upgrade Guide
The TUF Gaming A15, A16, and F15 are ASUS’s budget gaming laptops — and they’re excellent for upgrades. All models have two DDR5 SO-DIMM slots (up to 64GB) and two M.2 NVMe SSD slots. At their price point, you can buy the base configuration and upgrade RAM and storage yourself for significant savings.
TUF models use 100W USB-C PD charging. Thunderbolt support is limited — most TUF models use USB-C without Thunderbolt.
ASUS ProArt StudioBook — Upgrade Guide
The ProArt StudioBook 16 is ASUS’s workstation for creative professionals. It features two DDR5 SO-DIMM slots (up to 64GB), two M.2 2280 NVMe Gen 4 SSD slots, and two Thunderbolt 4 ports — the only ASUS laptop with dual TB4. Charging is 100W USB-C PD.
This is the best ASUS choice for users who need both upgradeability and professional docking station compatibility.
ASUS ExpertBook Series — Upgrade Guide
The ExpertBook B5 and B7 are ASUS’s business laptops competing with Lenovo ThinkPad and HP EliteBook. Both models offer two DDR5 SO-DIMM slots (up to 32–64GB) and standard M.2 NVMe SSD access. Charging is 65W USB-C PD. Thunderbolt support varies by configuration.
ASUS Charger Compatibility
ASUS has moved almost entirely to USB-C Power Delivery across its current lineup. The barrel plug charger is now reserved for a few budget VivoBook configurations.
| Series | Charger Wattage | Connector |
|---|---|---|
| ZenBook 14/S14 | 65W | USB-C PD |
| VivoBook | 45–65W | USB-C PD or barrel (varies) |
| ROG Zephyrus G14/G16 | 100W | USB-C PD |
| ROG Strix G16/G18/SCAR | 100–150W | USB-C PD |
| TUF Gaming A15/A16/F15 | 100W | USB-C PD |
| ProArt StudioBook 16 | 100W | USB-C PD |
| ExpertBook B5/B7 | 65W | USB-C PD |
See our laptop charger compatibility guide for recommended USB-C PD chargers at every wattage.
ASUS Docking Station Compatibility
ZenBook, ROG Zephyrus, ROG Strix, and ProArt models all include Thunderbolt 4 and support any Thunderbolt docking station. VivoBook, TUF, and ExpertBook models may have limited Thunderbolt support — check the specific model. DisplayLink docks are an alternative for models without Thunderbolt.
See our laptop docking station compatibility guide for dock recommendations.

Frequently Asked Questions
Can I upgrade the RAM in my ASUS ZenBook?
No. All current ZenBook models (ZenBook 14, S14, S16) use soldered LPDDR5X memory. Only the SSD is replaceable. Order with the RAM you need — 16GB minimum recommended for 2026.
Does the ROG Zephyrus G14 have upgradeable RAM?
Partially. The Zephyrus G14 has a hybrid configuration — one RAM module is soldered (typically 16GB) and one SO-DIMM slot is user-accessible. You can add or replace the SO-DIMM module, but the soldered portion is fixed. Maximum total depends on configuration (typically 32–48GB).
Which ASUS gaming laptop is easiest to upgrade?
The TUF Gaming A16 is the easiest and most cost-effective to upgrade. It has two full DDR5 SO-DIMM slots (64GB max) and two M.2 NVMe SSD slots, all user-accessible. The ROG Strix G18 offers similar upgradeability with higher-end specs.
What SSD size do ASUS laptops use?
Most ASUS laptops use the standard M.2 2280 NVMe form factor. Some ultra-thin models (ZenBook) may use M.2 2230. Check your model’s service manual before purchasing — a 2280 SSD won’t fit in a 2230 slot.
Can I use a 65W charger on an ASUS ROG gaming laptop?
Technically yes — USB-C PD is safe at any wattage — but a 65W charger won’t sustain an ROG laptop under gaming load (they need 100–150W). The laptop will charge very slowly or lose battery while gaming. Use a 100W+ charger for any ROG model.
