Beelink SER9 Max Review: 10 Gigabit Ethernet and Dual SSD Slots Under 800 Grams
An eight-core Ryzen 7 H 255 with Radeon 780M graphics, 64GB of DDR5 and a 10GbE port, cooled by a vapor chamber in a 135 mm aluminium-look chassis.
The Beelink SER9 Max takes the eight-core, sixteen-thread AMD Ryzen 7 H 255 with Radeon 780M graphics and pairs it with 64GB of dual-channel DDR5-5600 and a 1TB Gen 4 drive, leaving a second M.2 2280 slot free. Its standout feature at this price is the 10 Gigabit Ethernet port, four times the throughput of the 2.5G ports usual in the category, alongside a USB4 port that is Thunderbolt 3 compatible and can carry DisplayPort or deliver power. Cooling is a vapor chamber with a silent fan and a dedicated SSD heatsink, in a chassis that weighs only 780 grams. The trade-offs are Wi-Fi 6 rather than Wi-Fi 7, an external 100W adapter, and no SD reader or fingerprint sensor, but as a compact machine for development, office work and light gaming on a fast network it is well balanced.

Who is the Beelink SER9 Max for?
This is a productivity machine for someone who wants real CPU headroom without paying flagship prices. The Ryzen 7 H 255 provides eight cores and sixteen threads up to 4.9 GHz, which handles containers, virtual machines, code compilation, photo and video editing, and 4K playback comfortably, while Radeon 780M graphics with 12 compute units cover light gaming and GPU-accelerated tasks. The 10 Gigabit Ethernet port is the reason to pick it over cheaper mini PCs: on a fast home network it moves large project files or media libraries at speeds a 2.5G machine cannot. At 135 mm square and 780 grams it also travels easily between desks.
What stands out on paper
Networking and storage are where the specification is unusually generous. The single 10GbE port pairs with a USB4 port that supports Thunderbolt 3 devices, DisplayPort 1.4 output and power delivery, so a dock or external SSD enclosure works without adapters. Two M.2 2280 PCIe 4.0 slots each take up to 4TB, so total storage can reach 8TB, and the two SO-DIMM slots hold 64GB of DDR5-5600 with room for 128GB. Display output covers HDMI and DisplayPort at 4K 240Hz plus the USB4 port, driving three screens. Cooling is the MSC 2.0 design with a vapor chamber, a silent fan and a separate SSD heatsink, which matters in a chassis this small, and there are two 3.5 mm audio jacks, one front and one rear. Beelink includes an HDMI cable and backs it with a three-year warranty.
What to know before you buy
Wireless is Wi-Fi 6 with Bluetooth 5.2, a step behind the Wi-Fi 7 machines now common at this price, which matters more if the 10GbE port will not be used. Power comes from an external 19V adapter rather than an internal supply, so a brick joins the desk. The chassis leaves out several conveniences: no SD card reader, no fingerprint sensor, no Kensington lock slot, and no built-in speakers or microphone, so calls need a headset. Graphics are integrated Radeon 780M, so demanding modern titles at high settings are out of scope. There is also only one Ethernet port, so no wired redundancy despite its speed.
Is the Beelink SER9 Max worth it?
For its price band it is a strong package, mainly because the 10 Gigabit port and the dual Gen 4 storage slots are features usually reserved for more expensive machines. Buyers who need Wi-Fi 7, an internal power supply or extras like an SD reader and fingerprint login will find them on other models, sometimes from Beelink's own range. Buyers who want a small, quiet eight-core desktop that can saturate a fast wired network and grow to 8TB of storage will get their money's worth here.
Frequently asked questions
Does the Beelink SER9 Max have 10 Gigabit Ethernet?
Yes, it has a single 10GbE port, which is four times faster than the 2.5G ports found on most mini PCs in this class. There is no second wired port.
Is the USB4 port Thunderbolt compatible?
Beelink lists the USB4 port as supporting Thunderbolt 3, along with DisplayPort 1.4 output and power delivery, so most docks and external enclosures will work.
How much storage can it take?
Up to 8TB, using two M.2 2280 PCIe 4.0 slots that accept 4TB each. A 1TB drive is installed, leaving the second slot free.
How many monitors can it drive?
Three, via HDMI and DisplayPort, both supporting up to 4K at 240Hz, plus the USB4 port with DisplayPort 1.4.
Can the memory be upgraded?
Yes. It ships with 64GB of DDR5-5600 across two SO-DIMM slots and supports up to 128GB.
Does it include a power supply in the chassis?
No, it uses an external 19V adapter rated at about 100W. The region-appropriate adapter is included in the box along with an HDMI cable.
