Looking to sell your ASUS ROG Zephyrus M16 (2023) — model GU604 for cash? Released in early 2023, this generation was a major internal revamp of the M16 line: ASUS borrowed the higher-power motherboard and tri-fan “Pulsar” cooling from the ROG Flow X16, letting the thin 16-inch chassis run a 13th-gen Intel Core i9 with up to an NVIDIA GeForce RTX 4090 at 145W — well above the 120W ceiling of the previous M16. It shipped in three main configurations, all sharing the same GU604 model code: GU604VY (RTX 4090), GU604VZ (RTX 4080), and GU604VI (RTX 4070). Because your exact GPU tier and display panel swing the resale value substantially, identifying your precise configuration is what locks in an accurate quote. This page covers the 2023 GU604 only — if your M16 carries a GU603 model code (the 2021/2022 generation with 12th-gen Intel and RTX 30-series graphics), that's a different laptop with different value, and you'll want its own page. Select your components using our tool above for an instant cash offer, or trade it in toward your next device — more on our trade-in service below.

Which M16 do you have? GU604 vs. GU603

ASUS reused the M16 name across two very different generations, and they look similar from the outside. The number printed on the sticker on the bottom of your laptop is the reliable way to tell them apart. Look for a code beginning with GU604 (this page) or GU603 (the earlier model). The quickest internal tell: the 2023 GU604 runs a 13th-gen Core i9-13900H and RTX 40-series graphics, while the older GU603 runs a 12th-gen Intel chip with RTX 30-series graphics.

GU604 — 2023 (this page)

  • Intel 13th-gen Core i9-13900H (Raptor Lake)
  • NVIDIA RTX 4070 / 4080 / 4090

Graphics (GPU)

  • GU604VY: NVIDIA GeForce RTX 4090 16GB GDDR6 (up to 145W)
  • GU604VZ: NVIDIA GeForce RTX 4080 12GB GDDR6 (up to 145W)

  • Includes a MUX Switch with NVIDIA Advanced Optimus and G-Sync; Intel UHD graphics handles low-power tasks

Memory (RAM)

  • DDR5-4800 across two SO-DIMM slots

  • Both slots are user-accessible and upgradable to 64GB — a key change from the older GU603, which had 16GB soldered onboard plus a single slot

Storage

  • M.2 PCIe 4.0 x4 NVMe SSD
  • 512GB / 1TB / 2TB factory capacities
  • Two M.2 2280 slots for dual-drive setups, expandable up to 4TB total

Display & audio

Display

All GU604 units use a 16-inch, 16:10, matte, non-touch QHD+ (2560 × 1600) panel in one of two grades. The premium option is a ROG Nebula HDR Mini-LED panel with 1024 local-dimming zones, a 240Hz refresh rate, 3ms response, up to ~1100–1200 nits peak HDR brightness, and 100% DCI-P3. The standard option is a QHD+ IPS panel at 165Hz, 3ms, 500 nits, and DCI-P3 coverage. Both are Pantone Validated with a MUX switch and G-Sync. The Mini-LED panel commands a higher resale value, so note which one you have.

Audio

Six-speaker system (2 tweeters + 4 woofers) with Dolby Atmos and Smart Amp, tuned by Dolby, plus a 3.5mm combo headphone/mic jack and AI noise-cancelation for the mics.

Ports & connectivity

The GU604 keeps a full port set for a thin 16-inch machine, with USB-C on both edges for charging flexibility. The power adapter connects on the left rear edge to keep the cable out of the way.

Frequently asked questions

01 How do I confirm I have the 2023 GU604 and not the older GU603?
Turn the laptop over and read the sticker on the bottom panel. The model code will start with GU604 (2023, this page) or GU603 (2021/2022). You may also see a longer suffix like GU604VY, GU604VZ, or GU604VI — that last letter tells us your GPU tier. To double-check inside Windows, type “About your PC” into the Start menu and look at the processor: a Core i9-13900H confirms the 2023 GU604, while a 12th-gen chip (like an i9-12900H) means you have the older GU603. Our ASUS model-number guide shows exactly where to look, and the general find-your-laptop-model-number guide covers reading your full specs in Windows.
02 Can I sell a Zephyrus M16 with cosmetic wear or hardware problems?
Yes. We buy the M16 in every condition. Whether yours is pristine, has scuffs on the lid, a worn or swollen battery, dead pixels or Mini-LED blooming issues, loud or failing fans, broken hinges, or won't boot at all, just set the matching condition grade in the tool above to lock in a firm cash offer. Accurate grading up front gives you the most reliable quote.
03 Do I need to wipe or remove my SSDs before shipping?
Back up your personal files and game libraries to an external drive or the cloud, then sign out of your Microsoft account and Windows profile before boxing the laptop. You don't need to open the machine or pull the M.2 drives yourself — and since the GU604 can hold two SSDs, do double-check you've backed up both if you added a second one. Our team runs certified multi-pass data sanitization on every incoming drive. See our data erasure protocols for the full process.
04 Which configuration raises my GU604 trade-in value the most?
The GPU is the single biggest value driver. A GU604VY (RTX 4090) commands a notably higher payout than a GU604VZ (RTX 4080) or GU604VI (RTX 4070). After that, the Mini-LED Nebula HDR display is worth more than the standard IPS panel, and larger RAM (up to 64GB) and storage (up to 4TB) configurations lift the offer further. If you're upgrading rather than just cashing out, our trade-in service lets you apply that value directly toward your next device — a lot of sellers don't realize this is an option. You can see how it works on our How It Works page, and first-time sellers may find this walkthrough handy: Sell Your Laptop: First-Time Seller Edition.
05 How fast do I get paid, and who covers shipping?
Once your Zephyrus M16 reaches our facility and passes functional testing, payment is approved within two business days. You can pick a fast electronic payout — PayPal, Venmo, Zelle, or CashApp — or a physical check by mail. Your prepaid, insured shipping label is completely free from start to finish.
