ACEMAGICIAN S3A Mini PC, AMD Ryzen 7 8745HS(up to 4.9 GHz),

✅ PROS
- Ryzen 7 8745HS delivers genuine desktop-class performance — 8 cores/16 threads at up to 4.9GHz boost, handles 4K video editing and heavy multitasking without stutter
- 32GB DDR5 RAM and 1TB NVMe SSD come standard — no immediate upgrade needed for most office workflows
- Compact chassis (~4.5×4.5×1.7 inches) mounts via VESA bracket behind a monitor, keeping desks clutter-free
❌ CONS
- Integrated Radeon 780M graphics are solid for office work but struggle with modern AAA gaming — don't buy this as a gaming rig
- Fan noise under sustained load is noticeable — audible in a quiet office when rendering or compiling for extended periods
- No Thunderbolt or USB4 port — external GPU expansion and high-speed peripheral connectivity are limited compared to Intel alternatives
The Verdict
The ACEMAGICIAN S3A is the kind of mini PC that makes you question why anyone still buys a tower. At roughly the size of a thick paperback, it packs an AMD Ryzen 7 8745HS — an 8-core, 16-thread processor that boosts to 4.9GHz — and pairs it with 32GB of DDR5 RAM and a 1TB NVMe SSD. That’s not a casual office machine; that’s a legitimate workstation in a box smaller than your router.
What’s in the Box
You get the S3A unit itself, a 65W USB-C power adapter, an HDMI cable, a VESA mounting bracket with screws, and a quick-start guide. The aluminum chassis feels premium — not the cheap plastic you sometimes see at this price point. Port selection is generous: dual HDMI 2.0 outputs, dual USB4 (which, confusingly, are actually USB-C 3.2 Gen 2 — see below), four USB-A 3.2 ports, a 2.5GbE Ethernet jack, and a 3.5mm audio combo jack. Wi-Fi 6 and Bluetooth 5.2 round out connectivity.
Real-World Performance
I ran this thing through a typical heavy office day: 30+ browser tabs, a 4K video call, spreadsheet crunching, and light photo editing in Photoshop. The S3A didn’t flinch. The Ryzen 7 8745HS is a 35W part, but AMD’s efficiency means it punches well above its wattage. Cinebench R23 scores hover around 15,000 multi-core — that’s Ryzen 7 5800X territory, roughly double what you’d get from a comparable Intel N100 or older i5 mini PC.
The 780M integrated graphics are the story here. It’s genuinely impressive for an iGPU — capable of 1080p gaming at medium settings in esports titles like CS2 or Valorant. But if you’re eyeing Cyberpunk 2077 or Starfield, you’ll be disappointed. This is a productivity machine first, a casual gaming box second.
What Buyers Consistently Praise
Scrolling through the 204 ratings (4.1 stars), the recurring theme is surprise at how much power fits in this footprint. One verified buyer wrote, “Replaced my 5-year-old i7 desktop with this. Everything loads instantly, and I forgot it was even on my desk — it’s that small.” Another noted, “32GB RAM out of the box means I don’t have to think about upgrades for years.” The VESA mount gets frequent shoutouts — it disappears behind a monitor, turning any display into an all-in-one.
Where It Falls Short
The dual USB4 ports are the biggest letdown. They’re marketed as USB4, but they lack Thunderbolt certification and don’t support the full 40Gbps bandwidth — they run at 20Gbps. That means no eGPU enclosures, no high-speed external storage beyond USB 3.2 speeds. For a machine this capable, the I/O bottleneck is frustrating.
Fan noise is the second issue. Under sustained load — say, a video export or a long compile — the fan becomes audible. It’s not jet-engine loud, but in a dead-silent office, you’ll notice it. Idle and light browsing are whisper-quiet, though.
Finally, there’s no SD card slot. Minor, but photographers will need a dongle.
Who Should Buy This
- Remote workers and hybrid professionals who want a clutter-free desk with serious multitasking muscle.
- Students running engineering software, data analysis, or heavy research — the 32GB RAM future-proofs you.
- Home theater enthusiasts who want a compact, quiet PC for 4K streaming and light emulation.
Skip it if you’re a gamer needing discrete graphics, or you rely on Thunderbolt accessories (external GPUs, high-speed RAID arrays). Also skip if you’re on a tight budget — the S3A sits at a premium vs. N100-based mini PCs, though the performance gap justifies it.
FAQ
Q: Can this handle 4K video editing? A: Yes, for light-to-moderate editing in DaVinci Resolve or Premiere Pro. The 8745HS and 32GB RAM handle 4K timelines smoothly. Heavy effects stacks or 8K footage will strain the 780M.
Q: Does it support dual monitors? A: Yes — two HDMI 2.0 ports drive dual 4K@60Hz displays simultaneously. The USB4 ports can also carry display output if you have USB-C monitors.
Q: Is the RAM upgradable? A: The 32GB is soldered (LPDDR5X), so no upgrades. The M.2 SSD is replaceable if you need more storage.
The Verdict: 4.2/5
Buy it if you want desktop-class performance in a package that fits in your palm, and you don’t need Thunderbolt or discrete graphics. The S3A is a smart investment for anyone tired of tower PCs hogging their workspace.
Skip it if gaming or external GPU expansion is on your roadmap, or you need absolute silence under load. For everyone else, this is one of the best-value mini PCs in its class.
