Minisforum wrote to us to say it released the new Mercury Series EM680 mini PC. This wasn’t a surprise because Minisforum seems to launch or release a new mini PC nearly every week. However, the new EM680 stands out somewhat for offering potent processing power in one of the smallest chassis around. This new palm-sized PC occupies a total volume of 250 ml (8.25 fl. oz) and weighs 238 g (0.52 pounds) – which is smaller and lighter than a standard can of soda.

It is worth looking more closely at the processing power within the EM680. Regular readers will be familiar with the AMD Ryzen 7 6800U, which was launched in June 2022, and boasts Zen 3+, RDNA 2, and DDR5 technologies. This processor, the top model in the U series, was popular in handheld PCs from the likes of Ayaneo, OneXPlayer, and GPD announced in 2022. However, our direct experience with this processor can be pondered over in our Asus Zenbook S 13 OLED review from a year ago. In summary, we were pleased with the performance, but the slim Asus chassis wasn’t great for dissipating heat. Hopefully the Minisforum’s boxy vented case with ‘Cold Wave 2.0’ liquid metal cooling will be capable enough for when the 6800U gets both CPU and GPU cores stressed.

Shifting the spotlight back onto the Minisforum Mercury Series EM680 mini PC, it complements the decent 15-28W processor with enough ports so that it doesn’t feel too restricted by the extreme compact form. The worst thing about the design from an enthusiast point of view is probably that the RAM cannot be upgraded. One must choose 16 GB or 32 GB of onboard LPDDR5-6400 at the time of purchase.

The M.2 2230 slot for the main storage device is an understandable compromise considering the size, but these smaller M.2 drives are getting more popular and larger capacity models will proliferate thanks to devices like the Steam Deck and ROG Ally.

Some other product highlights not mentioned thus far include: support for up to three 4K@60Hz display outputs, flexible power in via either of the two USB 4 Alt PD ports, and the inclusion of a compact 65 W GaN Type-C power adapter.

Minisforum is selling the EM680 with at least $100 off its MSRPs at the time of writing. It is possible to buy one from $399 now (16 GB RAM, 512 GB SSD), as well as models at $449 (32/512 GB) and $489 (32/1024 GB).

    The caption promised "can of pop".

    That's a box !

    The form factor is very intriguing, as one is getting a highly potent laptop performance inside a fraction of the volume.
    There is, however, the obvious elephant in the room: how about thermals and thottling?
    Can such a miniature device be sufficiently cooled without running into severe throttling after 30 seconds?
    Great CPU compute power is as miuch worth as its cooling solution.
