Unboxing
In the box there is the laptop, 330W Barrel-type AC adapter, 100W USB Type C AC adapter, Asus ROG Gladius III Mouse, user guide, and warranty card booklet.
The box comes with a handle for easy carry. 
Instructions to slide the insert with the arrow side up. 
Laptop is held on by two tabs, no other protections. 
Pushing down on the arrow makes the laptop accessible. 
Underneath the laptop is the 330W charger and the mouse. 
In the hidden compartment is the USB Type C 100W AC Adapter. 
Here are all the accessories included in the box.
The bottom of the case is well vented with the exhaust at the back and sides. The airflow is really good and is not affected when the lid is open or not. There are stands in the middle of chassis as well, providing better stability when typing on a flat surface.
For repairs and storage upgrades, the ROG Strix Scar 16 G634JZR has 11 screws on the bottom. Always remember to be careful around snap-on clips around the laptop which tend to be fragile and will break without the proper care and tools especially as the laptop ages. Inside, the cooling is handled by a seven heat pipes and a three fan which is good for use on battery mode but is not enough when the laptop is maxed out while plugged in. Both the CPU and GPU uses liquid metal instead of thermal paste
There are 2 SSD slots with only 1 used out of the box. The SSD comes with tape and not thermal pads with can be of concern in Gen 4 SSDs. The second SSD slot is right above WiFi module making double-sided SSD unusable. The RAM is upgradeable and comes in 2 sticks of 16GB DDR5 SoDIMM. The battery is removable with only 4 screws, but the connector to the motherboard is underneath a fan that is held on to with 3 additional fans.
Review
Battery and Charging
One of the most important things for laptop users is being able to use the device away from a wall outlet. 3 different loads over 2 different profiles was tested on this laptop. All measurement are taken from HWInfo.
On regular load, the laptop was set at 50% brightness, 25% volume, silent fan profile, balance performance with no battery saving on native refresh rate. Wifi is used with good strength. Half of the screen is on Google Sheets on light mode, with the second half of the screen as Microsoft Edge browsing the web with multiple tabs open. In the background, a live youtube video of Lofi Girl, “lofi hip hop radio – beats to relax/study to” is being played at 1080p. There are also no peripherals attached.
The laptop was only able to reach a little over 3.5 hours with a realistic basic work load. For basic work, this laptop is not suited out of the box as the laptop consumes too much power. This is quite concerning for a 90Whr battery laptop.
With that in mind, for the Heavy and Movie load, the 2 were tested on both silent and high performance. This was done to see if there are any differences in battery life.
For Heavy Load, the laptop was set at 50% brightness, standard fan profile, high performance mode with no battery saving. Consecutive runs of Cinebench R23 on all cores was run to simulate heavy CPU load for people who would use the laptop for rendering as well. At barely over an hour, the laptop’s 90 WHr battery is depleted making it only good enough for quick renders. In Silent mode, the battery depleted at the same rate.
On movies, the laptop was set at maximum brightness and maximum volume, standard fan profile with no battery saving. VLC was used to play SDR and HDR video clips in both H.265 and AV1 codec. In high performance mode, 90 minutes is barely enough to cover most popular movies. In this mode, the GPU is responsible in decoding the video, thus causing higher power consumption.
In silent mode, the laptop automatically selected to only use the integrated graphic for video decode reducing power consumption to increase battery life to 3 hours and 10 minutes. This is just enough to watch through 1 long movie. Streaming the movie over the internet will reduce battery life, while reducing the brightness and volume will impove it.
The ROG Strix Scar 16 G634JZR is able to charge up around 50% in 30 minutes with the 330W AC Adapter, and fully charged in 99 minutes from 5%. If not needed, it might be best to not charge past 90% as the charging speed slows down to a crawl.
With the included 100W USB Type C AC Adapter, the laptop is fully charged in 2 hours and 22 minutes. Asus specifies in the manual to only use 100W 20V 5A for USB Power Delivery. Using a higher rated charger is not recommended by Asus.
Do note that the higher charging speed applies for charging from a very low state as we can see in the chart. Using the laptop while plugged in can also affect the speed of the charging as the device will prioritize your work over topping up your battery.
With the 330W AC Adapter, the ROG Strix Scar 16 G634JZR is unable to charge over 10W when the laptop is gaming at full power. The test was cut short as charging the laptop is taking too long. At this rate, the laptop will be full at around 8 hours.

| ΔE Average | 0.84 | 0.94 | 0.84 | 0.83 |
The laptop on stock delivers the best experience with the only downside being the 7200K white point which is cooler than what is optimal. With an average ΔE of only 0.84, the laptop can be used for color-sensitive work. Upon testing, all of the special profiles provided does not significantly improve the accuracy of the display. A 570+ nit MiniLED display is significantly bright allowing you to easily work even in brighter environments.

6900-7400K is cooler than the desired 6500K white point for more color accurate use case.
CPU Benchmarks
GPU Benchmarks
Storage Benchmarks
The ROG Strix Scar 16 G634JZR comes with the SK hynix PC801 HFS001TEJ9X101N on stock. This is a TLC PCIe 4.0 x4 DRAM NVMe SSD rated at 7000MB/s Sequential Read and 6500 MB/s Sequential Write. This is an alternate version of a more well known SSD called the SK hynix Platinum P41.
Here are four benchmarks run at large test sizes.
The storage interface of the ROG Strix Scar 16 G634JZR fully utilizes the Gen 4 x 4 PCIe lanes. The experience of using the ROG Strix Scar 16 G634JZR should be snappy enough for general use, but do note that the experience will change with heavy use as temperatures and drive limitations are hit.
With the lack of proper cooling for the SSD, the SSD easily hits 70C contributing to performance losses in the benchmarks. This is best showcase in the Atto Benchmark wherein the SSD started to drop below 2GB/s at the 12MB mark. The temperature also does not drop down when the load stops as the heat needs to dissipate with near zero airflow.
Do note that this temperature can be hit even during the Movie load test done with an 18Mbps local video file in less than 30 minutes. Upon observation, the performance doesn’t affect most use case except for large file transfer.
Keyboard
The typing experience of the ROG Strix Scar 16 G634JZR is okay for typing as key wobble is minimal and the spacing between keys is sufficient. Trackpad placement was not an issue for typing but your experience may vary. The large arrow keys is great for most people but the other navigational keys being nested in the arrow keys will need getting used to. The right most side of the keyboard is filled media keys that may or may not be optimal for the target audience for this laptop which is gamers. For heavy-users of the numpad, the trackpad numpad is not for everyone as touch typing is notably harder without the tactile feel.
Here is the list of keyboard shortcuts:
| Fn + Esc | Fn Lock | Fn + F10 | Toggle Touchpad |
| Fn + F1 | Mute Speakers | Fn + F11 | Sleep |
| Fn + F2 | Toggle Keyboard Backlight (Off, 1-3) | Fn + F12 | Airplane Mode |
| Fn + F3 | Toggle Keyboard Backlight (Off, 1-3) | Fn + R. Ctrl | Context Menu |
| Fn + F4 | ROG Aura | Fn + Win Key | Win Key Lock |
| Fn + F5 | Toggle Profile (Silent, Performance, Turbo) | Fn + Up | Page Up |
| Fn + F6 | Snipping Tool | Fn + Down | Page Down |
| Fn + F7 | Brightness Down (-10%) | Fn + Left | Home |
| Fn + F8 | Brightness Up (+10%) | Fn + Right | End |
| Fn + F9 | Projector (Multiple Display Out Setup) |
