Full answer
ASUS USA’s tech specs for the Zenbook 14 (UX3405) list two models, UX3405MA (Intel Core Ultra Series 1: Ultra 9 185H, Ultra 7 155H, Ultra 5 125H) and UX3405CA (Intel Core Ultra Series 2: Ultra 9 285H, Ultra 7 255H, Ultra 5 225H). Both list the same power supply: “TYPE-C, 65W AC Adapter, Output: 20V DC, 3.25A, 65W”, a 75Wh battery, and 2× Thunderbolt 4 ports “with support for display / power delivery”. So a 65W USB-C PD charger that delivers 20V / 3.25A from one port is the match. A bigger brick (100W) is safe but won’t charge this laptop faster than ASUS’s 65W adapter; it just leaves headroom for a phone on a second port. A smaller one (45W) usually still charges, slower, and may not keep up under heavy load — ASUS lists no adapter below 65W for the UX3405.
Other Zenbook 14 models list different adapters: for example ASUS lists a 68W USB-C adapter (20V / 3.4A) for the Zenbook 14 UX3480 (Qualcomm). Check the model number on the label under your laptop (UX3405…) before you buy. For other ASUS laptops see the ASUS USB-C charger page.

What wattage to buy
What wattage to buy
- 65W USB-C PD — the adapter ASUS lists for Zenbook 14 UX3405MA and UX3405CA (20V / 3.25A). See 65W chargers.
- 100W USB-C PD — fine if one brick also charges a phone or tablet; the Zenbook 14 still draws what it needs. See 100W chargers.
- Under 65W — ASUS lists no smaller adapter for this model, so expect slower charging, especially while you work.
Which cable
The right cable
Use a USB-C to USB-C cable rated for at least 3A (60W); for the full 65W at 20V / 3.25A, a 5A (100W) e-marked USB-C cable leaves headroom. The UGREEN bundle above includes two 100W USB-C cables; the Apple 2 m cable is rated up to 240W. See the USB-C cable guide.
