The System76 Adder WS is a 15.6-inch Linux workstation laptop built for developers, engineers, and creators who need NVIDIA GPU acceleration on a machine that runs Pop!_OS or another Linux distribution out of the box. It pairs a 13th Gen Intel Core i9 with a discrete RTX GPU, aimed squarely at CUDA workloads, 3D rendering, and compilation jobs that would choke a thin-and-light. Because it ships assembled and supported by System76 rather than mass-produced, used units hold interest from the same technical buyer pool that bought it new. Pick your GPU configuration and condition in the tool above for an instant cash offer that adjusts as you answer a few questions, and see how the process works before you box anything up. If a laptop sale is the right move, you can also sell your System76 laptop directly from here.

Confirm you have the Adder WS

The fastest way to confirm the exact build is inside the OS. On Pop!_OS or GNOME-based distributions, open Settings → About to see the processor and confirm it reads Intel Core i9-13th Gen. To check the installed GPU, open a terminal and run nvidia-smi, which reports whether the card is an RTX 4070 or RTX 4050 laptop GPU. If the machine won't boot, the GPU model is also listed on the underside service label.

RTX 4070 configuration

  • Higher-tier discrete GPU, confirmed via nvidia-smi or lspci
  • Pairs with the same i9-13th Gen processor across configurations
  • Typically the higher resale tier of the two GPU options

RTX 4050 configuration

  • Entry discrete GPU option for this model
  • Same chassis and processor as the RTX 4070 build
  • Confirm with nvidia-smi if the sticker is worn or missing

Prefer a visual check? The Adder WS uses an aluminum chassis with a matte dark finish and rear-venting exhaust for the GPU. Look for the System76 logo on the lid rather than a manufacturer badge from Clevo or another ODM, and check that the keyboard deck shows a full-size layout with dedicated arrow keys.

Core hardware configurations

Processor

  • Intel Core i9, 13th Gen mobile
  • Single processor option across both GPU configurations

Graphics

  • NVIDIA RTX 4070 laptop GPU, or
  • NVIDIA RTX 4050 laptop GPU
  • GPU tier is the single biggest lever on resale value for this model

Display & audio

Display

A 15.6-inch panel tuned for the kind of sustained GPU workloads this configuration targets, whether that means rendering previews or compiling shaders. Confirm panel condition for dead pixels and hinge flex during the condition step above, since screen damage is graded separately.

Audio

Built-in stereo speakers cover calls and casual playback. Buyers running audio-critical workloads typically route through external interfaces or headphones rather than the internal speakers.

Ports & connectivity

The Adder WS carries a workstation-style port layout rather than the stripped-down set found on ultrabooks, so most buyers can dock external displays and storage without an adapter.

Wired
  • USB-C with video output and power delivery
  • USB-A
  • HDMI
  • Gigabit Ethernet
  • 3.5mm headset jack
Wireless
  • Wi-Fi
  • Bluetooth

Battery, build & more

Battery

Runtime leans toward workstation use rather than all-day portability. Expect shorter unplugged sessions when the RTX GPU is under sustained load, which is typical for any laptop in this performance class.

Software

Ships configured for Pop!_OS, System76's own Linux distribution, and works with most other mainstream distributions if the buyer prefers a different setup.

Market positioning

A niche but steady resale category. Buyers searching for this model already know they want NVIDIA compute under Linux, which narrows the audience but keeps demand consistent for well-kept units.

Frequently asked questions

01 How do I find the model number and exact configuration?
Check inside the OS rather than relying on memory. Open Settings → About in Pop!_OS or GNOME to confirm the processor reads Intel Core i9-13th Gen, then open a terminal and run nvidia-smi to see whether the installed GPU is an RTX 4070 or RTX 4050. If the laptop won't power on, the underside service label lists the GPU and build details, and System76's own order confirmation email is a reliable backup if you still have it.
02 How do I tell it apart from a System76 Oryx Pro?
Look at the GPU tier and chassis build first. The Oryx Pro is System76's thinner, more portable line, while the Adder WS is built around a heavier, workstation-focused chassis meant to sustain higher-wattage RTX GPUs under load. If the underside label or nvidia-smi output shows an RTX 4070 or 4050 paired with the heavier aluminum body described above, you have an Adder WS rather than an Oryx Pro.
03 Can I sell it with damage, a dead battery, or a lock on it?
Yes, in most cases, and the condition picker above accounts for it. A cracked screen, a battery that no longer holds charge, or a unit that won't power on can still be sold, though the offer adjusts to reflect the repair work involved. Before shipping, remove any firmware or BIOS password you've set, and clear any full-disk encryption keys or user accounts so the drive can be wiped and tested. A locked or encrypted drive that can't be verified will lower or delay your offer.
04 What raises the trade-in value the most?
GPU tier matters most, since an RTX 4070 configuration typically outvalues an RTX 4050 unit in otherwise identical condition. After that, a clean screen with no dead pixels, a battery that still holds a reasonable charge, and the original charger all move the offer upward. Cosmetic wear on the lid or deck matters less than functional issues like a failing hinge, a GPU that throttles hard, or ports that no longer make contact.
05 How do I erase it and remove my accounts before shipping?
Back up anything you want to keep first, since this process is permanent. Boot into the Pop!_OS recovery partition (hold the appropriate boot key at startup, usually listed in System76's documentation) and choose the option to reinstall or refresh the OS, which wipes the drive. If you'd rather erase manually, boot from a USB installer and use a disk utility like GNOME Disks, or run a secure erase against the NVMe drive from a live session. Sign out of and remove any cloud accounts you've linked, such as Nextcloud, Dropbox, or a System76 support login. Once the drive is wiped, ship it in with the included box or your own packaging; shipping is free and insured, and payment goes out after testing by PayPal, Venmo, Zelle, CashApp, or check. Full steps are on the data erasure protocols page.
