GMKtec's K8 Plus is one of our favorite mini PCs to ever pass through our testing space, especially if you're looking for a compact video editing machine that can be upgraded down the line. Right now, the GMKtec K8 Plus mini PC for $650 (was $900) at Amazon.
This configuration features the high-performance Ryzen 7 8845HS processor, paired with 16GB DDR5 RAM, and 1TB SSD. But the real highlight for us is the connectivity. Specifically, this mini PC comes with dual USB4 ports and an OCuLink port for connecting an eGPU for graphics-intensive workloads.
August 13. Since first finding this deal, I've checked prices and the GMKtec K8 Plus is still priced at $650 right now.
Why we recommend it
In our 4.5-star review, we called it an "understated mini PC that delivers far more power than you'd expect for the price," and found it handled demanding day-to-day tasks with total ease during testing, backed by a genuinely capable set of upgrade options.
The OCuLink port is the standout feature here. It gives this mini PC a genuine path to external GPU performance that most machines this size simply don't offer, which matters if your needs might grow beyond what the integrated Radeon 780M can handle.
Combined with dual 2.5G Ethernet and 16GB of upgradeable RAM, this machine is built to keep pace as your workload changes, not just handle what you need today. For my money, it's one of the best mini PCs we've tested.
Price Context & Historical Value
According to CamelCamelCamel, this is the lowest price I've seen on Amazon for the 16TB/1TB configuration. However, I've previously seen the 32GB/1TB version selling for $630 back in February - before the RAMpocalypse truly hit and we saw price risess across the board. Previously, the 32GB/2TB version was selling for $810 (down from $940), a deal that ended today.
Alternatively, GMKtec has the 32GB/1TB model for $740 (was $750), and so does Walmart and Newegg. At Amazon, I've spotted the 32GB/2TB model for $900, while the 32GB/512GB is impossibly overpriced at $740. If you want more RAM, the other options above are better value with additional storage.

Should you buy it?
✅ Buy the GMKtec K8 Plus if...
You want desktop-class performance and expandability in a footprint that fits behind a monitor. The upgradeable RAM and dual M.2 storage, plus an OCuLink port for a future external GPU, make this a genuinely future-proof pick for a dorm room, home office, or secondary workstation.
❌ Skip the GMKtec K8 Plus if...
You care about design details — our review noted the transparent twist-off top cheapens what's otherwise a clean, metal-cased build. You'll also need an external graphics card connected if you need serious dedicated graphics power, since the integrated Radeon 780M is fine for light gaming but not built for demanding titles alone.
The Catch: What to know before you buy
Our main design complaint in the review was the transparent, twist-off top panel, which looks a bit cheaper than the rest of the metal chassis suggests it should. On the performance side, the integrated Radeon 780M graphics handle light gaming and everyday creative work well.
However, anyone chasing serious frame rates in demanding titles will want to rely on the OCuLink port for an external GPU rather than expect it from the iGPU alone.
For desktop-class performance in a genuinely small footprint, this is one of the better mini PC deals we've tracked. You can see more in our guide to the best mini PCs we've tested, and save with the best mini PC deals we've uncovered this week.
