TRIGKEY S6 / S6 Pro
Published on
The TRIGKEY S6 is a compact Windows desktop for office work, browsing, and a three-monitor desk, sold in two builds that share one case: the S6 and the better-equipped S6 Pro. Both use AMD processor designs from 2022 and cost more than several other mini PCs on the same chips, but they add a USB4 port that the two cheaper models compared below lack. As of October 2026, neither build has owner reviews, so there is no owner record on fan noise, heat, or reliability.

Ports, displays, and case
The front panel holds two USB-A ports at 10Gbps, a USB-C port at 10Gbps for data, a combo audio jack, the power button, and a pinhole for clearing the CMOS. The back holds the barrel power input, HDMI 2.0, DisplayPort 1.4, the USB4 port, a USB-A 2.0 port, and the 2.5Gb Ethernet jack. Three monitors can run at once: DisplayPort reaches 4K at 144Hz, HDMI 2.0 reaches 4K at 60Hz, and the USB4 port carries the third display. Wireless is WiFi 6 and Bluetooth 5.2. The case is a square box about 4.9 by 4.7 inches and 2 inches tall, with perforated vents down both sides.
TRIGKEY supports Wake-on-LAN and automatic power-on after a power cut, which helps if the S6 runs as an always-on machine. A VESA bracket ships in the box, so it can hang behind a monitor. The power adapter is external. Both builds ship with Windows 11 Pro installed, and TRIGKEY offers a one-year warranty.
Ryzen 5 6600H versus Ryzen 7 7735HS
The S6 uses the AMD Ryzen 5 6600H, a 6-core, 12-thread chip that boosts to 4.5GHz and scores about 18,900 in PassMark’s CPU test. The S6 Pro uses the AMD Ryzen 7 7735HS, an 8-core, 16-thread chip that boosts to 4.75GHz and scores about 24,300. The 7735HS arrived in 2023 under a 7000-series name, but it uses the same Zen 3+ cores and Radeon 680M graphics as the 2022 Ryzen 7 6800H. For comparison, the Zen 4 Ryzen 7 7840HS that followed scores about 28,900 and pairs with the newer Radeon 780M.
For graphics, the S6 Pro’s Radeon 680M has 12 compute units, twice the 6 units of the S6’s Radeon 660M, and it is the version to pick for 1080p gaming at low to medium settings in lighter or older titles. TRIGKEY publishes its own benchmark figures: 3,737 points in Cinebench R20 and P7437 in 3DMark 11 Performance for the S6, and 5,224 points for the S6 Pro in Cinebench (TRIGKEY does not name the version).
Memory, storage, and cooling
Memory sits in two DDR5 SO-DIMM slots, so both builds can grow to 64GB with two 32GB modules. The S6 ships with 16GB of DDR5-4800 in dual channel, and the S6 Pro ships with 32GB. The 500GB SSD is an M.2 2280 NVMe drive in a PCIe 4.0 x4 slot, and TRIGKEY quotes up to 2TB for that slot. TRIGKEY’s specs disagree on the second drive position (a 2.5-inch 7mm SATA bay or a second PCIe 4.0 M.2 slot), so open the case before buying a second drive.
TRIGKEY cools the board with two fans, one on the CPU and one for the rest of the system.
Conclusion
The S6 fits a desk that needs three monitors and a USB4 port for a fast external drive or dock, with room to grow to 64GB of memory. The S6 Pro’s Radeon 680M handles 1080p gaming at low to medium settings in lighter or older titles, while the S6 suits office work and browsing. Wake-on-LAN, power-on after a power cut, and the VESA bracket suit an always-on machine behind a monitor. With no owner reviews yet, fan noise and reliability are unknown.
Skip it if you do not need USB4, because both builds list for more than several mini PCs on the same chips with more memory or storage. The Getorli GT103 pairs the Ryzen 5 6600H with up to 32GB and 1TB at a lower list price than the 16GB S6, and the Beelink SER5 MAX uses the Ryzen 7 7735HS and lists below the S6 Pro with a 1TB option; neither has a USB4 port. For a faster TRIGKEY, the S7 Pro moves to the Zen 4 Ryzen 7 7840HS. The Mini PC Comparison Chart lists the rest.
Upgrades
Accessories that fit the TRIGKEY S6 / S6 Pro's USB4 or Thunderbolt ports.
Core X V2
A Thunderbolt 5 enclosure that Razer lists as working with Thunderbolt 4 and USB4 hosts; it fits a four-slot card and needs an ATX power supply.
DEG2 eGPU Dock
Connects over USB4 or Thunderbolt 5, with an OCuLink input behind a switch, and adds an M.2 slot; it needs an ATX or SFX power supply.
Breakaway Box 850 T5
Has an 850W power supply built in, so only the graphics card is extra, and works with Thunderbolt 4 and USB4 Windows PCs.
TS4 Thunderbolt 4 Dock
An 18-port dock that CalDigit lists for Thunderbolt 4 and USB4 hosts, with 2.5GbE and a DisplayPort 1.4 output.
TBT4-UD5 Thunderbolt 4 Dock
Two HDMI ports drive two 4K60 monitors from one Thunderbolt 4 or USB4 port on a Windows PC.
Revodok Max 208 Thunderbolt 4 Dock
Adds three Thunderbolt 4 ports for dual 4K60 displays plus gigabit Ethernet; it has no HDMI port, so monitors connect over USB-C or an adapter.
Frequently Asked Questions
Are the TRIGKEY S6 and S6 Pro the same machine?
They share the same case and port layout. The differences are the processor (Ryzen 5 6600H or Ryzen 7 7735HS), the integrated graphics (Radeon 660M or Radeon 680M), and the installed memory (16GB or 32GB). Both ship with a 500GB SSD.
How much faster is the Radeon 680M in the S6 Pro?
PassMark’s G3D Mark puts the Radeon 680M at 3,996 and the Radeon 660M at 3,143, so the 680M scores about 27 percent higher. On paper the 680M has 12 RDNA 2 compute units at up to 2.2GHz, against 6 units at 1.9GHz in the 660M.
Does the TRIGKEY S6 have Thunderbolt?
No. The rear Type-C port is USB4 at 40Gbps without Thunderbolt certification. USB4 hosts do not have to support Thunderbolt 3 devices, so check a Thunderbolt dock’s USB4 compatibility before you buy one for the S6.
What memory should I buy to upgrade the S6 to 64GB?
Two 32GB DDR5 SO-DIMM laptop modules. The Zen 3+ memory controller in both chips runs DDR5 at 4800MT/s, so faster-rated modules work but run at that speed. Install them as a matched pair to keep dual-channel bandwidth.
Can the TRIGKEY S6 run Linux?
The Ryzen 6000 platform, the Radeon 660M and 680M graphics, and the S6 Pro’s Intel i226-V Ethernet controller all have drivers in current mainline Linux kernels. TRIGKEY does not say which Ethernet or WiFi chip the S6 uses, so check wireless support under Linux before you depend on it.
