MSI Raider A18 HX A9WIG-082US / Lenovo Legion Pro 7 16IRX9H (83DE0005US)

175 W is the highest GPU power MSI gives in this chassis; CPU and GPU together can draw up to 260 W (OverBoost Ultra). The desktop RTX 5080 is a separate card.

175 W is the highest total graphics power Lenovo allows in this model; going above NVIDIA’s 60–150 W base range for the RTX 4080 Laptop GPU relies on Dynamic Boost 2.0. The desktop RTX 4080 is a different product.

The processor’s stacked extra cache, called 3D V-Cache, keeps frequently used game data close, which helps frame rates especially in large open-world games.

The Mini LED backlight dims zones individually for high HDR brightness and deeper blacks; DisplayHDR 1000 is the tier certifying 1,000-nit peak brightness. Because of the high resolution, refresh is limited to 120 Hz.

DisplayHDR 400 is VESA’s entry-level HDR tier; it does not require local dimming, so HDR looks less striking than on OLED or Mini LED. 240 Hz and G-SYNC give smooth, tear-free motion in fast games. Lenovo notes that “IPS” may also cover similar panel types such as PLS, ADS and AHVA.

Both slots come filled; reaching 96 GB means fitting two 48 GB modules.

This configuration ships with a single module, so memory runs single-channel until a matching module is added to the second slot. Lenovo’s 32 GB limit is based on the modules it has tested.

The second M.2 slot runs at Gen4; an added SSD there tops out at Gen4 speed.

PCIe 4.0 x4 allows up to 8 GB/s in theory; real speed depends on the SSD. There is no card reader.

The USB4 ports are listed as compatible with Thunderbolt 4 accessories, but MSI does not state separate Thunderbolt certification; PD 3.1 allows USB-C charging, while full gaming power needs the 400 W adapter.

140 W charging over USB-C needs Lenovo’s own adapter; other adapters may deliver less. Up to four independent displays including the internal one are supported; Lenovo lists up to 4K/60 Hz for external outputs. Ethernet is 1 Gbit/s, not 2.5G, and supports Wake-on-LAN.

UHS-III gives faster reads than UHS-II with compatible cards; the full-size slot reads camera cards without an adapter.

The IR camera enables Windows Hello face sign-in; the physical shutter blocks the camera.

99.9 Wh is just under the limit for laptop batteries allowed on planes.

The weight excludes the 400 W adapter.

Liquid metal transfers heat between the chip and cooler more efficiently than standard paste, which makes servicing more delicate.

Lenovo says Super Rapid Charge reaches 30% in 10 minutes, 70% in 30 minutes and 100% in 80 minutes. 99.9 Wh sits just under the usual airline battery limit. Lenovo quotes 10.4 hours of 1080p video playback at 150 nits.
