Buy Razer Power Adapter - 400W | Gaming Laptops Accessories | Razer.com

Will this power adapter work with all the Razer 18” laptops that have 4090m GPUs and not cause any damage?


I have seen cases where a power adapter is too strong and ends up bricking the laptop, so I want to be very careful.
The 330w has never been in stock ever since I ordered my laptop years ago!

    If the voltage (V) is the same as your old power brick, then no worries.
