The MSI laptop in question lets the GPU use up to 165W. See eg. AnandTech's review of that MSI laptop, which measured 290W at the wall while gaming: https://www.anandtech.com/show/16928/the-msi-ge76-raider-rev...
(IIRC, it originally shipped with a 155W limit for the GPU, but that got bumped up by a firmware update.)
