Beelink SEI14 Mini PC

Updated on September 13, 2026

The Beelink SEi14 is a compact mini PC built on Intel’s Core Ultra 5 125H, a 14-core, 18-thread chip with integrated Intel Arc graphics. It ships with 32GB of DDR5 (upgradeable to 96GB) and a 1TB PCIe 4.0 SSD, with a second M.2 slot for up to 8TB total. Ports include Thunderbolt 4, an Intel 2.5GbE adapter, Wi-Fi 6, and triple 4K display output over HDMI, DisplayPort, and USB-C.

The aluminum chassis is the part reviewers compare to a Mac mini, and the layout suits productivity and home-lab duty. The Arc graphics handle 4K playback and light gaming, but not modern AAA titles at high settings, and reviewers note it runs warm under sustained load.

Fast on multi-core work, slower on graphics

Reviewers measured Cinebench R23 multi-core between about 12,000 and 14,000 (Robtech 13,225 stock and 14,109 in performance mode, VirtualizationHowto 13,451, Tek Syndicate 11,956), with Geekbench 6 multi-core around 11,000. That is solid productivity throughput, though Robtech noted the AMD-based SER8 edges it in single-core (by almost 8% in his Cinebench run). RAM goes to 96GB of DDR5 across two SO-DIMM slots, and there are two M.2 NVMe slots for up to 8TB.

Graphics come from Intel Arc, which is a step up from older Intel iGPUs but lands behind AMD’s Radeon 780M, a comparison Tek Syndicate drew directly. Frame rates at 1080p low-to-medium vary widely by title: Robtech measured about 108 FPS in Counter-Strike 2, Lon.TV 45 to 50 FPS in Red Dead Redemption 2, and Tek Syndicate about 41 FPS in Cyberpunk 2077 on low. The Thunderbolt 4 port takes an external GPU for more; Robtech ran an RTX 3070 through it for roughly 40 FPS in Cyberpunk 2077 at 4K.

The vapor-chamber cooler keeps the unit quiet at idle, but under sustained load the CPU peaks near 89 to 92C and the fan climbs toward 50 dBA; as Tek Syndicate put it, “the Core Ultras are always warm.” Idle power is low (Lon.TV measured about 32W, and VirtualizationHowto saw 14 to 15W under Proxmox), rising to the high 70s to mid-80s of watts under full load.

What reviewers found

Lon.TV

Lon.TV described the look as “very much an Apple inspired” design and the fan as “super super quiet,” and measured a 3DMark Time Spy of 3,649 with Red Dead Redemption 2 at 45 to 50 FPS (1080p low). He flagged the missing VESA mount and Wi-Fi that can need extra drivers on Linux, and called it a strong productivity box priced above AMD equivalents.

Robtech

Robtech ran it against the AMD SER8, calling it “a good-looking unit with nice build quality” but noting “the SER8 beats it in single-core Cinebench by almost 8%” and leads in gaming. He valued it instead for Intel media features like AV1 hardware encoding, and demonstrated an external RTX 3070 over Thunderbolt 4 (around 40 FPS in Cyberpunk 2077 at 4K).

Tek Syndicate

Tek Syndicate logged Cinebench R23 multi-core at 11,956 and Cyberpunk 2077 at 41 FPS on low, and credited the vapor-chamber cooling. He said “Intel’s finally here to game,” while noting that the Arc graphics trail AMD’s Radeon 780M and that “the Core Ultras are always warm,” with noise reaching 50 dBA under load.

VirtualizationHowto

VirtualizationHowto reviewed it as a home-lab host and singled out the Intel 2.5GbE adapter, which works with VMware ESXi where many budget minis do not, alongside 96GB DDR5 support. He measured low idle power under Proxmox (14 to 15W) versus ESXi (33 to 34W) and called it a tidy, ESXi-friendly virtualization box whose main limit is a single network port.

Carey Holzman

Carey Holzman set up a barebones SEi14 bought secondhand and spent the session on support rather than benchmarks. He found the model gone from Beelink’s own site: “It is no longer made. There’s no links to it. There’s no history or archive that we can find online from Beelink that ever promoted this, ever showed the specs.” After a clean Windows 11 install he counted “nine unknown devices” in Device Manager and called the vendor’s BIOS listing for the 125H model a mess. He still endorsed this CPU tier for business use, saying “anything higher than that, we’re going to be spending a lot more money and dealing with potential complaints of fan noise.”

A quiet Intel box for home labs and multi-monitor desks

The 96GB RAM ceiling, dual M.2 slots, Thunderbolt 4, and the ESXi-friendly Intel 2.5GbE adapter suit productivity, multi-monitor work, 4K video, or a home-lab host, in a case that stays quiet at idle. AV1 hardware encoding makes it a reasonable pick for content workflows too.

Gaming is the weak spot. The Intel Arc graphics trail AMD’s Radeon 780M, the chip runs warm under load, and it costs more than comparable AMD minis. Buyers who want stronger integrated graphics or a VESA mount should look elsewhere. To compare other models, see Starry Hope’s Mini PC Comparison Tool.
