The Beelink SER8 is the refined everyday desk companion, winning on whisper-quiet acoustics, premium unibody aluminum aesthetics, and built-in dust filtration.
ABuy the Minisforum UM790 Pro if:
- You need maximum display flexibility (UM790 Pro features 2× HDMI 2.1 and 2× USB4 to drive up to four 4K 120Hz/144Hz displays simultaneously).
- You want dual full-speed 40Gbps USB4 ports for connecting an external GPU (eGPU) and high-speed NVMe storage dock simultaneously.
- You want active thermal heatsink cooling directly on both internal M.2 NVMe SSD slots.
- You prefer the slightly higher peak GPU boost clock (2800 MHz on Ryzen 9 7940HS vs 2700 MHz).
BBuy the Beelink SER8 if:
- You prioritize near-silent acoustics (~32dB under typical loads thanks to its vapor chamber and quiet fan).
- You value premium build quality with a seamless unibody CNC aluminum chassis and bottom metal dust filter.
- You want the newer AMD Ryzen 7 8845HS processor featuring an integrated Ryzen AI NPU for local AI workflows.
- You want dual M.2 2280 PCIe 4.0 slots supporting up to 8TB total storage.

Frequently Asked Questions
Can both of these Mini PCs handle modern gaming?
Both Mini PCs use the AMD Radeon 780M integrated graphics (RDNA 3, 12 CUs). They run esports titles (Valorant, CS2, Rocket League) smoothly at 1080p 60–120fps. For demanding modern AAA games like Cyberpunk 2077 or Black Myth: Wukong, they run comfortably at 1080p Low settings with FSR enabled at 40–55fps. Neither replaces a dedicated discrete GPU desktop.
Can you connect an external GPU (eGPU) to these Mini PCs?
Yes. Both feature 40Gbps USB4 ports that support eGPU enclosures. The Minisforum UM790 Pro has an advantage here because it has two USB4 ports, allowing you to connect an eGPU while still having a spare 40Gbps port for high-speed external storage.
Which one runs quieter under load?
The Beelink SER8 runs noticeably quieter. It uses a vapor chamber thermal solution and near-silent fan curve tuned to roughly ~32dB under typical loads. The UM790 Pro uses Cold Wave 2.0 with liquid metal, which cools effectively but has a smaller, higher-RPM fan over the SSD/RAM that can become audible during intense rendering.
