What if you didn't need a desktop at all?
That's the premise behind the One PC philosophy — the idea that a single, powerful machine can handle everything: gaming, working from home, streaming, content creation, and anything else you throw at it. No separate work laptop. No dedicated desktop tower sitting on the floor. Just one machine that adapts to whatever mode you're in. We explored the same idea with the Samsung S26 and DeX mode — turning a phone into a full desktop. This time, we're doing it with a gaming laptop, and the result is even more capable.
The problem has always been the transition. Going from "gaming rig" to "workstation" on a laptop meant plugging in a power cable, a monitor cable, a USB hub, your keyboard, your mouse, your headset — every single time you sat down. And unplugging all of it when you wanted to take the laptop somewhere. It was a daily ritual that made the whole "one PC" idea feel like more trouble than it was worth.
Thunderbolt 4 changes that. Specifically, the combination of the ASUS ROG Strix G16 (2025) and the Plugable Thunderbolt 4 Dock (TBT4-UD5) turns that whole cable ritual into a single plug. One cable in — and your full desktop setup is live. One cable out — and you're walking out the door with a powerhouse gaming laptop.
Here's how to set it all up, and why this combo makes the One PC dream actually work in 2026.
The Foundation: ASUS ROG Strix G16 (2025)
Before anything else, the laptop has to be worth building around. The ROG Strix G16 (2025) clears that bar easily.
At its core is an Intel Core i7-14650HX — a 16-core, 24-thread processor that handles heavy multitasking without breaking a sweat. Pair that with an NVIDIA GeForce RTX 5060 Laptop GPU built on the new Blackwell architecture, and you're looking at a machine that can push serious frame rates in modern games while simultaneously running OBS, Chrome, Discord, and Spotify in the background. The RTX 5060 also brings DLSS 4 with Multi Frame Generation, which is a game-changer for performance headroom — you can crank settings higher and let the AI fill in the frames. If you're wondering whether the 8GB of VRAM is enough for 2026 titles, we did a full breakdown on that exact question.
The display is a 16-inch FHD+ panel with a 165Hz refresh rate and 3ms response time, presented in a 16:10 aspect ratio that gives you more vertical space than a standard 16:9 screen. When you're not plugged into external monitors, this is a legitimately great screen for both gaming and productivity. ASUS added an ACR anti-reflective coating this year that reduces glare noticeably in bright rooms.
Under the hood, 16GB of DDR5-5600MHz RAM and a 1TB PCIe Gen 4 SSD keep things fast. Wi-Fi 7 is onboard for wireless connectivity. Cooling is handled by a tri-fan system with an end-to-end vapor chamber and Conductonaut Extreme liquid metal on the chipset — which is why this laptop can sustain high-performance loads for hours without throttling the way cheaper gaming laptops do. If you want to understand exactly why laptops thermal throttle and what to do about it, our guide on laptop CPUs hitting 100% and 95°C covers it in detail.
The detail that makes all of this relevant to the workstation setup: the ROG Strix G16 (G615, Intel model) includes a Thunderbolt 4 port. Not just USB-C. Not just USB4. Full Thunderbolt 4, running at 40Gbps, with DisplayPort and Power Delivery support. That single port is the key to everything that follows.
The Hub: Plugable Thunderbolt 4 Dock (TBT4-UD5)
The Plugable TBT4-UD5 isn't just any dock — it was named Wirecutter's Best Thunderbolt Dock of 2025 and carries Intel Evo certification. That distinction matters because it means the dock has been tested and verified to deliver the performance it promises, not just the specs on paper.
Here's what's packed into its 13-port design:
- 2× HDMI 2.0 — dual 4K 60Hz monitor output simultaneously
- 1× Thunderbolt 4 downstream port — 40Gbps, 15W charging, supports up to 8K single display
- 4× USB-A ports — a mix of 10Gbps and 5Gbps for peripherals and storage
- 1× USB-C port — 10Gbps for additional devices
- SD card slot + microSD card slot — for content creators pulling footage from cameras
- Gigabit Ethernet — wired internet without running a cable to the laptop directly
- 3.5mm combo audio jack — plug in your headset or speakers
- K-lock security slot — useful if the dock lives in a shared or office space
- 100W Power Delivery — charges the ROG Strix G16 through the same Thunderbolt cable (96W certified)
Because the ROG Strix G16 has a full Thunderbolt 4 port, the dock runs at full capacity. That means dual 4K displays, maximum data speeds, and full charging — nothing is limited or downgraded. If you had a laptop with only a non-Thunderbolt USB-C port, the dock would be restricted to a single external display. The TB4 port on this laptop avoids that entirely.
The One-Cable Setup: Step by Step
This is the part that makes the whole system worth it. Here's what the setup actually looks like:
What you need on your desk:
- The Plugable TBT4-UD5 dock, plugged into power and connected to your monitors via HDMI, your keyboard and mouse via USB-A, your headset via the audio jack, and your router via Ethernet
- A single Thunderbolt 4 cable running from the dock to your desk's edge (or a cable management clip)
When you sit down:
- Set the ROG Strix G16 on your desk
- Plug in the one Thunderbolt 4 cable
- Done
Both monitors come on. Your keyboard and mouse are live. Your headset is connected. Gigabit Ethernet is active. Your laptop is charging at 100W through that same cable. The whole process takes about three seconds.
When you leave:
- Unplug the one Thunderbolt 4 cable
- Close the lid
- Walk out
Your desk is still fully wired and ready for next time. The laptop is a completely untethered machine the moment that cable comes out.
Gaming Mode
Plugged into the dock, the ROG Strix G16 becomes a proper desktop gaming station. You've got two monitors to work with — put your game on the primary display and use the second screen for anything you want running alongside: a browser, a Discord window, a Spotify queue, or your stream dashboard. If you're still looking for an affordable second monitor to complete the setup, our review of the SANSUI 200Hz Curved Monitor is worth a read — it punches well above its price.
The Gigabit Ethernet through the dock is a meaningful upgrade for online gaming. Wi-Fi 7 on the ROG Strix G16 is excellent, but a wired connection eliminates the small but real variability in latency that even good Wi-Fi introduces. For competitive games, that stability matters.
The RTX 5060 with DLSS 4 handles modern titles well at 1080p and 1440p. Multi Frame Generation, which is exclusive to the Blackwell architecture, lets the GPU generate additional frames between rendered frames — meaning you can run higher quality settings and still hit smooth, high frame rates. Games that previously needed DLSS Performance mode to hit 144Hz can now run at Quality or Balanced and exceed that target easily.
The ROG's 360° RGB light bar syncs with your peripherals through ROG Armoury Crate, so if you have ROG or Aura Sync-compatible gear connected via the dock's USB ports, your entire setup lights up in sync. Speaking of peripherals — if you need a gaming mouse to plug into the dock, check out our Redragon M612 review — it's one of the best value gaming mice you can get right now.
Streaming Mode
The dual-monitor setup from the dock is exactly what streamers need. Put your game on Monitor 1 full screen, and run OBS Studio on Monitor 2. You can see your stream preview, chat, alerts, and scene switcher at all times without alt-tabbing out of your game.
The key advantage here is the NVIDIA RTX 5060's NVENC encoder. Hardware encoding offloads the stream compression from the CPU to the GPU's dedicated encoder block, which means your game performance is barely affected by streaming. The Blackwell-generation NVENC encoder produces better quality at lower bitrates compared to the previous generation — your stream looks sharper without needing to push more data to your viewers.
The Gigabit Ethernet connection through the dock is critical for streaming. Upload speed variability over Wi-Fi causes dropped frames in your stream — even brief fluctuations show up as visual artifacts for viewers. A wired connection through the dock eliminates that variable entirely. Combine that with a stable NVENC encode and you're pushing a clean, consistent stream without any dedicated capture card or streaming PC.
The SD and microSD card slots on the dock are a bonus for streamers who also create YouTube content. If you shoot supplementary footage on a camera or GoPro, you can pull the card and transfer footage directly through the dock at high speed, without needing a separate card reader cluttering your desk.
Work Mode
Here's where the One PC philosophy really earns its name. When it's time to work, nothing changes about your physical setup — you're still plugged into the same dock, the same two monitors, the same keyboard and mouse. What changes is software and lighting.
The ROG Strix G16 has a Stealth Mode that turns off all RGB lighting — the keyboard backlight, the light bar, all of it — with a single button press or a toggle in Armoury Crate. The laptop goes from gaming rig to a clean, professional-looking machine in an instant. If you're in a video call with your monitor behind you, your background goes from "clearly a gamer's setup" to just a sleek dark laptop.
The dual 4K monitors through the dock give you a serious productivity advantage over a single-monitor laptop setup. Put your main application on the primary screen and keep reference materials, communication apps, or documentation on the second. The productivity gain from dual monitors is well-documented — the simple act of not having to constantly switch between windows reduces friction in nearly every type of work.
The 100W charging through the Thunderbolt cable means your laptop never runs low at your desk. Unlike some docks that charge at 45W or 65W — enough to maintain charge but not replenish it under load — the Plugable TBT4-UD5 delivers enough power to keep the ROG Strix G16 topped up even during intensive tasks.
Is This Setup Worth It?
Let's be direct about who this makes sense for and who it doesn't.
This setup is worth it if: your laptop is your only machine, you work from home regularly and need a real desk setup, you want to game or stream without a separate desktop, or you travel or work from multiple locations and need the laptop to be genuinely portable when away from your desk.
This setup is overkill if: you never move your machine, you only game and don't need dual monitors or wired peripherals, or you're on a tight budget and a simpler USB-C hub would cover your needs.
The ROG Strix G16 and the Plugable dock aren't cheap individually. But compare the combined cost to buying a capable gaming laptop plus a separate workstation PC and a KVM switch to share peripherals between them — the math shifts quickly. One machine, one dock, one cable. That simplicity has real value. If you're still comparing gaming laptops before committing, our Lenovo Legion 7i 16" (2026) review is a good benchmark — it's the closest competitor at this spec level.
Final Thoughts
The One PC philosophy works best when the transition between modes is frictionless. That's exactly what this setup delivers. The ASUS ROG Strix G16 (2025) gives you the GPU power and Thunderbolt 4 port to make it real. The Plugable TBT4-UD5 dock turns that single port into a full workstation — dual 4K monitors, wired Ethernet, full-speed USB, charging, and audio — all through one cable.
Sit down, plug in, and you have a desktop. Unplug and walk away, and you have a portable gaming machine. No compromises on either end. That's not a workaround — that's just a better way to work.
