Ugreen has launched the LinkStation Pro, an upgraded external GPU dock that swaps its predecessor’s USB4 connection for Thunderbolt 5 while keeping the OCuLink port that made the original a favorite among handheld and mini PC owners. The dock went on sale in China on September 14, 2026, according to Notebookcheck, HotHardware, and other outlets, with a built-in 850W power supply and a price around 3,000 yuan, or roughly $450.
The timing matters. Ugreen eGPU dock demand has climbed alongside the handheld gaming PC boom and a wave of compact mini PCs that ship without room for a full-size graphics card. A Thunderbolt 5 eGPU dock priced under $500, sitting alongside a lower-latency OCuLink path, gives buyers of those machines a genuine upgrade route instead of a replacement purchase. This piece breaks down what actually changed, how the LinkStation Pro compares with Razer and ASUS alternatives, and what the move signals about where external graphics hardware is headed next.

What Ugreen Announced on September 14
Notebookcheck reported that Ugreen “launched the LinkStation Pro eGPU dock in China,” describing it as offering “a faster 80 Gbps Thunderbolt 5 connection alongside OCuLink.” The outlet also confirmed the unit “features a built-in 850 W power supply” and “140 W laptop charging,” an increase from the 100W charging output on the original LinkStation model. VideoCardz corroborated the core details in its own report, tying the new model to Ugreen’s existing LinkStation lineup rather than treating it as an entirely new product family.
HotHardware, which referred to the unit by the model number LinkStation Pro CM990, added more granular detail on the OCuLink side, noting it “provides up to 64Gbps of dedicated PCIe 4.0 x4 data throughput directly to the installed graphics card.” The same outlet described the power supply as an “integrated 850W Gold-rated ATX 3.1 PSU.” Russian outlet ixbt.com additionally reported that the dock supports GPUs from Nvidia, AMD, and Intel, not just one brand’s graphics cards, though the more specific series confirmation (RTX 40 and RTX 50 series) came from HotHardware alone.
None of the outlets that broke the story reported a confirmed US or EU release date. The initial listing and pricing are China-specific, which is consistent with how Ugreen rolled out the original LinkStation dock in January 2026 before it later reached other regions.
Full Spec Breakdown: LinkStation Pro
Stripped of marketing language, the LinkStation Pro’s spec sheet centers on three changes over the original LinkStation: a faster host connection, more charging headroom, and an unchanged but still substantial power budget for the graphics card itself. Here’s how the confirmed numbers stack up against the outgoing model.
| Spec | LinkStation (original, Jan. 2026) | LinkStation Pro (Sept. 2026) |
|---|---|---|
| Host connection | USB4, 40 Gbps | Thunderbolt 5, 80 Gbps |
| OCuLink port | Yes, 64 Gbps / PCIe 4.0 x4 | Yes, 64 Gbps / PCIe 4.0 x4 |
| Built-in PSU | 850W, 80 Plus Gold | 850W, 80 Plus Gold, ATX 3.1 |
| Laptop charging | Up to 100W | Up to 140W |
| Reported price | Launched in the US market | ~3,000 yuan (~$450), China launch |
| GPU compatibility | Desktop GPUs via OCuLink/USB4 | NVIDIA RTX 40/RTX 50 series confirmed; broader Nvidia/AMD/Intel support reported by ixbt.com |
The headline change is the host port. Thunderbolt 5 nearly doubles the bandwidth ceiling versus USB4, and Intel’s own Thunderbolt technology documentation confirms the standard is built to support up to 80 Gbps bidirectionally, with a boost mode that can push higher in one direction for specific workloads like external displays. For an eGPU dock, that extra bandwidth reduces the bottleneck between the graphics card and the host laptop or mini PC, though the OCuLink port remains the faster path in absolute terms for systems that support it directly.
Thunderbolt 5 vs. the Old USB4 Connection: What Actually Changed
It’s worth separating marketing bandwidth from real-world throughput. USB4 at 40 Gbps was already sufficient to run most modern GPUs without catastrophic bottlenecking, but Thunderbolt 5’s 80 Gbps ceiling gives the LinkStation Pro more headroom for high-refresh external displays running through the same port, plus faster file transfer if the dock is also used as a hub. The practical gaming performance delta between USB4 and Thunderbolt 5 eGPU setups tends to be smaller than the bandwidth numbers suggest, because most of the bottleneck in external GPU setups comes from the PCIe tunneling overhead itself, not raw port bandwidth.
That’s exactly why Ugreen kept OCuLink on the Pro model instead of dropping it. OCuLink skips USB or Thunderbolt tunneling entirely and routes a more direct PCIe 4.0 x4 connection at 64 Gbps, which is why enthusiast builds using mini PCs frequently favor it over Thunderbolt when the host hardware supports it. Notebookcheck’s earlier coverage of the original LinkStation specifically called out this OCuLink path as being tied to compatibility with mini PCs such as the Minisforum X1 Pro-470, a machine that exposes a dedicated OCuLink port rather than relying purely on USB4 or Thunderbolt.
850W and ATX 3.1: Why the Power Supply Is the Real Story
An 850W built-in power supply sounds like overkill for a dock meant to house a single graphics card, until you account for what current-generation flagship GPUs actually draw under load. HotHardware’s reporting specifically flagged the PSU as ATX 3.1 compliant and 80 Plus Gold-rated, which matters because ATX 3.1 power supplies are built around the 12V-2×6 connector standard designed to handle the transient power spikes that high-end Nvidia and AMD cards can pull for fractions of a second during heavy load. A PSU that isn’t ATX 3.1-rated can trigger unexpected shutdowns under those spikes even if its wattage looks adequate on paper.
Keeping the PSU wattage flat at 850W between the original LinkStation and the Pro model, while every other headline spec moved up, suggests Ugreen already judged 850W sufficient for the GPU tier it’s targeting. That aligns with HotHardware’s confirmation that RTX 40 and RTX 50 series cards are explicitly supported, both of which include power-hungry flagship SKUs that a smaller PSU couldn’t reliably feed.
Price and Availability: $450 in China, Everywhere Else Unclear
VideoCardz put the LinkStation Pro’s price at roughly $450, converted from the reported 3,000 yuan China listing, while HotHardware’s coverage aligned with the same range. That price point sits well below what buyers have historically paid for enclosures with comparable power delivery. It also undercuts most Thunderbolt-based alternatives on the market once you account for the fact that the price includes the power supply, unlike bare enclosures that require a separate ATX PSU purchase.
None of the outlets that broke the story, including Notebookcheck, VideoCardz, and HotHardware, confirmed a US, UK, or EU release date or price at the time of publication. Given that the original LinkStation eventually reached the US market months after its initial China-first launch in January 2026, a similar staggered rollout for the Pro model is plausible, though nothing beyond the China listing has been officially confirmed.
How the LinkStation Pro Stacks Up Against Razer Core X
Razer’s Core X remains one of the best-known names in the eGPU dock category, and it’s a useful yardstick precisely because it represents the previous generation’s approach. The Core X ships with a 650W internal ATX power supply (700W on the Core X Chroma variant) and connects over Thunderbolt 3, which tops out at 40 Gbps, less than half of the LinkStation Pro’s Thunderbolt 5 connection. The Core X also lacks an OCuLink port entirely, meaning it depends fully on Thunderbolt tunneling with no lower-latency alternative for compatible mini PCs.
On price, the Core X currently sells for roughly $299 to $300, which is meaningfully cheaper than the LinkStation Pro’s reported $450. Buyers weighing the two are effectively trading a lower price and a longer track record for a narrower power budget and half the host bandwidth. The Core X supports GPUs up to three slots wide and 12.99 inches long, according to detailed enclosure reviews, so physical card compatibility isn’t a major differentiator between the two docks.
ASUS ROG XG Mobile: A Different, Pricier Philosophy
ASUS takes a different approach entirely with the ROG XG Mobile. Rather than an open dock that accepts any standard desktop graphics card, ASUS bundles the enclosure with its own laptop-grade mobile GPU, connected over Thunderbolt 5 with a quoted 120 Gbps of throughput, higher than the LinkStation Pro’s 80 Gbps figure because ASUS’s implementation uses a proprietary connector rather than a standard Thunderbolt port for part of that bandwidth. The unit includes additional I/O most eGPU docks skip, including a 5Gb Ethernet port, an SD card reader, HDMI 2.1, and DisplayPort 2.1.
That flexibility comes at a steep cost. A bundle pairing the XG Mobile dock with a flagship RTX 5090-class mobile GPU has been listed at $2,499, more than five times the LinkStation Pro’s price, though that figure includes the graphics card itself rather than an empty enclosure. The XG Mobile is best understood as a premium, closed-ecosystem alternative aimed at ROG laptop owners rather than a direct competitor for buyers who already own a desktop GPU and just need an enclosure to house it.
eGPU Dock Comparison at a Glance
| Dock | Host connection | Built-in PSU | Price | GPU included? |
|---|---|---|---|---|
| Ugreen LinkStation Pro | Thunderbolt 5 (80 Gbps) + OCuLink (64 Gbps) | 850W, 80 Plus Gold, ATX 3.1 | ~$450 (China) | No, bring your own card |
| Ugreen LinkStation (original) | USB4 (40 Gbps) + OCuLink (64 Gbps) | 850W, 80 Plus Gold | Launched in US market | No, bring your own card |
| Razer Core X | Thunderbolt 3 (40 Gbps) | 650W ATX | ~$299-300 | No, bring your own card |
| Razer Core X Chroma | Thunderbolt 3 (40 Gbps) | 700W ATX | Higher than base Core X | No, bring your own card |
| ASUS ROG XG Mobile | Thunderbolt 5, 120 Gbps quoted | Not disclosed as standalone unit | $2,499 bundled with RTX 5090-class GPU | Yes, GPU included in bundle price |
The comparison makes the LinkStation Pro’s positioning clear. It undercuts the ROG XG Mobile on price by a wide margin while offering roughly double the bandwidth of the Razer Core X for a moderate premium, plus the OCuLink option neither Razer nor ASUS’s current lineup provides.
Why eGPU Docks Are Suddenly Relevant Again in 2026
External GPU enclosures spent several years as a niche product category, popular mainly with ultrabook owners who wanted occasional gaming performance without carrying a gaming laptop. That’s changed in 2026 for a few concrete reasons. The first is the explosion of handheld gaming PCs, from the Steam Deck to newer entrants, which ship with soldered, non-upgradable graphics silicon. An eGPU dock is the only way to meaningfully boost graphics performance on that class of device once you’re docked at a desk.
The second driver is the growth of compact mini PCs, many of which physically cannot fit a full-size desktop graphics card inside their chassis but do expose a Thunderbolt, USB4, or OCuLink port capable of driving an external one. Notebookcheck’s reporting specifically tied the OCuLink port on Ugreen’s dock to compatibility with mini PCs like the Minisforum X1 Pro-470, underscoring that this isn’t a hypothetical use case but one manufacturers are actively designing around.
A third factor is simply that modern GPUs draw more power than ever, which is why the jump to an 850W, ATX 3.1-rated PSU inside the dock itself matters more in 2026 than it would have a few product generations ago. An enclosure built around an older PSU standard risks instability with current flagship cards regardless of how fast its host connection is.
The Handheld Gaming PC Angle
Handheld gaming PCs are arguably the fastest-growing use case pulling buyers toward eGPU docks in the first place. These devices are built around efficient, power-constrained mobile chips that trade peak performance for battery life and portability, which is precisely the tradeoff an eGPU dock is designed to undo once the handheld is docked at a monitor. A Thunderbolt 5 or OCuLink connection lets a handheld effectively become a desktop-class gaming machine without needing a second, dedicated desktop tower.
The catch is that not every handheld exposes the right port. Devices limited to standard USB-C without full USB4 or Thunderbolt support won’t see the same benefit, and even among USB4-capable handhelds, actual eGPU performance varies significantly based on how well each manufacturer implemented PCIe tunneling in firmware. That variability is part of why OCuLink support, which bypasses tunneling limitations, has become a selling point rather than a niche afterthought on docks like the LinkStation Pro.
Mini PCs and the OCuLink Advantage
Mini PCs present a slightly different problem than handhelds. Many pack genuinely capable desktop-class processors into a case too small for even a compact graphics card, which means the entire system’s gaming or GPU-compute performance is capped by integrated graphics unless an external card is added. OCuLink solves this more cleanly than Thunderbolt tunneling because it routes PCIe lanes almost directly to the external card, with minimal protocol overhead, at up to 64 Gbps according to HotHardware’s reporting on the LinkStation Pro.
That’s a meaningful distinction for buyers doing GPU-accelerated workloads beyond gaming, including local AI inference or video encoding, where consistent throughput matters more than peak burst bandwidth. A dock that offers both Thunderbolt 5 and OCuLink, as the LinkStation Pro does, effectively hedges against the host system’s specific port limitations rather than locking buyers into one connection standard.
Historical Context: How eGPU Docks Got Here
External GPU enclosures trace back to early Thunderbolt 3 implementations, when Razer’s original Core line and similar products first proved that tunneling PCIe traffic over an external cable was viable for real gaming workloads, even with meaningful bandwidth loss versus an internal PCIe slot. Those early docks were expensive, often costing as much as a midrange graphics card on their own, and performance loss compared to a native desktop PCIe slot could run into double-digit percentages depending on the game and GPU pairing.
USB4’s arrival broadened the market by building Thunderbolt-like tunneling into a more widely adopted, lower-cost standard, which is what powered Ugreen’s original LinkStation dock in January 2026. Thunderbolt 5’s rollout in 2025 and 2026 represents the next step in that same lineage: more bandwidth, better power delivery standards like ATX 3.1, and, in Ugreen’s case, the added flexibility of OCuLink support that earlier Thunderbolt-only docks like the Razer Core X never offered.
Market Impact and Competitive Pressure
Ugreen pricing a Thunderbolt 5 eGPU dock at roughly $450, less than the price of many midrange graphics cards, puts direct pressure on both budget and premium competitors. Razer’s Core X remains cheaper, but it’s now two full Thunderbolt generations behind on host bandwidth and offers no OCuLink alternative. ASUS’s ROG XG Mobile sits at the opposite end, bundling in a GPU at a price more than five times higher, which positions it for buyers who don’t already own a desktop card rather than as a direct price competitor.
That leaves a gap in the market that the LinkStation Pro appears designed to fill: a Thunderbolt 5-capable dock, priced closer to Thunderbolt 3-era products than to premium bundled solutions, aimed squarely at handheld and mini PC owners who already own or plan to buy their own graphics card separately. If competitors like Razer, ADT-Link, or other OCuLink-focused enclosure makers don’t respond with comparable Thunderbolt 5 or OCuLink refreshes, Ugreen could capture a disproportionate share of this specific, fast-growing niche through 2027.
What This Means for Buyers Right Now
For buyers in China with a Thunderbolt 5-capable laptop, mini PC, or handheld, and a spare desktop GPU sitting unused, the LinkStation Pro’s roughly $450 price and 850W PSU make it a straightforward upgrade over the original USB4 LinkStation, provided the host device can actually take advantage of Thunderbolt 5’s extra bandwidth. Owners whose systems only support USB4 or OCuLink won’t see much benefit from paying extra for Thunderbolt 5 headroom they can’t use, and the original LinkStation or a comparable USB4-only dock may remain the more sensible purchase.
Buyers outside China face more uncertainty, since none of the outlets that broke this story confirmed international pricing or a release window. Anyone shopping today should treat US or EU availability as unconfirmed rather than imminent, and should compare confirmed China pricing against the Razer Core X’s roughly $300 price tag to decide whether the bandwidth jump is worth the premium once (and if) the LinkStation Pro reaches their region.
Predictions: Where eGPU Docks Go From Here
- Expect Ugreen to bring the LinkStation Pro to the US and EU within a similar window to the original LinkStation’s staggered rollout, likely stretching from late 2026 into early 2027, based on the pattern set by its predecessor.
- Razer and other Thunderbolt 3-era dock makers will likely face pressure to release Thunderbolt 5 refreshes of their own enclosures in 2027, given the bandwidth gap the LinkStation Pro has now highlighted.
- OCuLink support is likely to become a more common feature on competing eGPU docks rather than a Ugreen-specific differentiator, as more mini PC and handheld makers add native OCuLink ports.
- Pricing pressure from docks like the LinkStation Pro could push bundled solutions like the ROG XG Mobile toward offering unbundled, enclosure-only options at lower price points to stay competitive with open-standard docks.
- As AI inference and local model workloads grow on consumer hardware, expect eGPU dock marketing to increasingly target compute use cases alongside gaming, given the consistent PCIe throughput OCuLink-equipped docks can offer for sustained workloads.
The Bottom Line
The Ugreen LinkStation Pro isn’t a radical reinvention of the eGPU dock, but it is a meaningful generational step: doubling host bandwidth over its own predecessor, keeping the OCuLink option that made the original popular with mini PC and handheld owners, and holding its price well below premium bundled alternatives like the ROG XG Mobile. Whether that translates into a genuine shift in how gamers and creators handle graphics upgrades in 2026 depends heavily on whether Ugreen brings the dock beyond China, and on how quickly Razer, ASUS, and other enclosure makers respond with their own Thunderbolt 5 or OCuLink updates.
Frequently Asked Questions
What is the Ugreen LinkStation Pro?
It’s an external GPU (eGPU) dock from Ugreen that houses a standard desktop graphics card and connects to a laptop, mini PC, or handheld gaming PC via Thunderbolt 5 or OCuLink. It launched in China on September 14, 2026, according to Notebookcheck and other outlets.
How much does the Ugreen LinkStation Pro cost?
VideoCardz and HotHardware reported a price of roughly 3,000 yuan, or about $450, for the China launch. No international pricing has been confirmed.
What’s the difference between the LinkStation Pro and the original LinkStation?
The Pro model replaces the original’s USB4 (40 Gbps) host connection with Thunderbolt 5 (80 Gbps), increases laptop charging from 100W to 140W, and adds ATX 3.1 compliance to its 850W power supply. The OCuLink port and overall 850W PSU wattage remain unchanged from the original.
Does the LinkStation Pro work with AMD and Intel graphics cards, not just Nvidia?
HotHardware specifically confirmed support for NVIDIA GeForce RTX 40 and RTX 50 series cards. Separately, ixbt.com reported broader compatibility with Nvidia, AMD, and Intel external GPUs, though that claim comes from a single outlet rather than multiple independent confirmations.
How does the LinkStation Pro compare to the Razer Core X?
The Razer Core X uses an older Thunderbolt 3 connection (40 Gbps) and a smaller 650W power supply, and currently sells for around $299-$300. The LinkStation Pro offers double the host bandwidth via Thunderbolt 5, a larger and newer-standard 850W ATX 3.1 power supply, plus an OCuLink option the Core X doesn’t have, at a higher reported price of roughly $450.
Is OCuLink better than Thunderbolt 5 for an eGPU dock?
OCuLink routes PCIe lanes more directly to the graphics card with less protocol overhead, which is why it’s often preferred on systems that support it, such as certain mini PCs. Thunderbolt 5 offers higher raw bandwidth (80 Gbps vs. OCuLink’s reported 64 Gbps) and works with a much wider range of laptops and handhelds. Which is “better” depends on what ports your specific host device supports.
When will the Ugreen LinkStation Pro be available outside China?
No outlet that broke the story confirmed a US, UK, or EU release date. The original LinkStation dock followed a China-first launch pattern before later reaching other markets, so a similar staggered rollout for the Pro model is possible but unconfirmed.
Why does an eGPU dock need an 850W power supply?
Current flagship graphics cards, including Nvidia’s RTX 50 series, can draw significant sustained power along with brief transient spikes well above their rated wattage. An 850W, ATX 3.1-compliant supply, as confirmed for the LinkStation Pro by HotHardware, is built to handle those spikes reliably rather than risking shutdowns under load.
