Beelink SER9 Pro mini-PC with AMD Ryzen 7 H 255 review | Infinium-tech

Introduction and unboxing

Beelink is nothing if not prolific. It becomes a mini-PC for almost anyone. Today, we have a premium model of it – the SER9 Pro, specifically, a unit powered by the AMD Ryzen 7 H 255 processor.

This particular model comes standard with 32GB of RAM and a 1TB Crucial SSD and is priced at $640/£609/€740. You have a choice of Frost Silver and Space Gray color options.

Inside the box, the SER9 Pro packs a power adapter and an HDMI cable.

Design and port

The SER9 Pro measures 13.5 centimeters tall and has a height of about 5 centimeters. Its weight is 780 grams. The Beelink rotating acorn logo is at the top. There are four microphones on the front of the machine, along with a light-up power button. There is nothing on the left and right. The vents for the heat sink are on the back.

In terms of ports, you get one USB-C and one USB-A (both 10Gbps) on the front, along with a 3.5mm audio jack.

On the back, there’s a DC power port, a USB4 port (40Gbps), an HDMI 2.0 (4k@240Hz), DisplayPort 1.4 (4K@240Hz), and three more USB-A ports (two 2.0 480Mbps and one 3.2 10Gbps). Finally, there is an Ethernet 2.5G port.

Four USB-A ports and just two USB-C, only one of which is USB4, doesn’t bode well for the 2025.

Our SER9 Pro comes with dual speakers, but you can save $40 and choose a mini-PC without a microphone or speakers. The sound quality of the speaker is okay and the volume is not impressive.

The bottom panel is ventilated and sits on two rubberized feet. To open the mini-PC, you need to remove four rubber feet to access the Phillips head screws.

Carefully lift up the panel. You then unscrew the heat sink (two more screws) to access the two M.2 slots. One houses the main SSD and the other houses the Wi-Fi card. You can put a second SSD in the other slot and use only the Ethernet port.

If you opt for the $139 optional Mate SE dock you can get a few extra ports and two more M.2 PCIE 4.0 slots. It is designed for the SER9 Pro (and SER9). What makes this dock special is its 80Gbps throughput, which is much higher than your average Amazon dock.

The Mate SE adds another 2.5G Ethernet port, two USB-A 3.0 (5Gbps), and two USB-C (one 80Gbps), and power input. There’s also an SD 4.0 (300MB/s read, 200MB/s write) card slot on the side.

The Mate SE features its own active cooling fan for cooling and 360° vents at the bottom.

It comes with two special USB-C cables for precise mounting on a mini-PC. Use one cable if you want to mount the dock above the PC and another to mount it below it.

Performance and fan noise

The Ryzen 7 H 255 is built on AMD’s 4nm Zen 4 architecture with RDNA 3 graphics. The processor has 8 physical cores and 16 threads. It has 32GB LPDDR5X 6400MT/s RAM and the spec graphics is said to be AMD Radeon 780M. There is no built-in NPU, so the processor and GPU handle AI tasks.

The mini-PC has three-layer cooling – a vapor chamber, a heat sink and a fan. Beelink reckons it’s almost as quiet, at 32dB.

We ran our usual set of benchmarks to assess performance. The Ryzen 7 H 255’s score is mostly lower than the Intel 255H we tested inside the Honor MagicBook Art 14 2025. The Ryzen 7 H 255 is also a step down from the Ryzen AI 9 365 inside the Minisforum X1.

You can do some casual gaming on the Radeon 780M. Beelink reckons you’ll get 56fps in Forza Horizon 4, 74fps in PUBG and 128fps in League of Legends. We got about 36fps at medium settings in Civilization 7 at 1080p, and about 40fps in FC 25 at Ultra settings at 1080p, and about 30fps at medium settings in Cyberpunk 2077.

We ran our usual stress tests on the Beelink SER9 Pro and found that the performance of the Ryzen 7 H 255 is excellent. The processor started at 54W and 4.9GHz but then soon dropped to around 38W and 4.5GHz. After a brief stint at 31W and 4.3GHz, it was able to establish itself at 42W at 3.9GHz, where it stayed for the remainder of the test.

The fan was running loudly, but its sound is not audible in a normal office environment. You can see the thermal map – all the heat went into the heat sink on the back of the mini-PC.

The preloaded Crucial P3 Plus SSD is an absolutely great unit. It posted good speeds, although far from the best PCIe 4.0 drives we’ve seen (about 7,000MB/s). The unit is DRAM-less, which means on paper it’s slower than higher-end SSDs with DRAM, but in most real-world scenarios you’re unlikely to notice a difference.

conclusion

The Beelink SER9 Pro with AMD Ryzen 7 H 255 is an excellent choice of mini-PC for most users and most needs. The AMD processor provides more than enough power for most tasks, and its built-in Radeon 780M graphics are capable of some advanced 1080p gaming.

Then there’s the good port selection, optional 80Gbps dock to expand on that, and solid dual-M.2 slots inside. You can easily set up this machine as an office PC, a backup PC, a casual gaming PC, you name it.

You can find the Beelink SER9 Pro on the manufacturer’s website as well as on Amazon. In the US, as configured with the Ryzen 7 H 255, 32GB of RAM, a 1TB SSD, and Windows 11 Pro, the SER9 Pro costs $609. Amazon.com and at €699 Amazon Germany (Although it is not always in stock). Mate SE dock for SE9 Pro is $169 in America,
