DeskMini UM690L barebone mini PC

The DeskMini UM690L is a barebone mini PC built around an AMD Ryzen 9 6900HX processor with eight cores and integrated Radeon 680M graphics. It ships with 16GB of soldered LPDDR5 6400 memory and a 1TB PCIe 4.0 SSD, targeting users who need a compact desktop for productivity or light creative work without assembling components themselves.

Sustained load behaviour

Under continuous load the eight-core processor runs up to 4.9 GHz while the Radeon 680M graphics operate at 2400 MHz, both cooled inside the slim chassis. The system supports triple display output at 8K 60 Hz via HDMI 2.1 and USB4 plus 4K 60 Hz via DisplayPort 1.4, so extended multi-monitor workloads remain stable. Network traffic uses a 2.5 Gbps Ethernet port alongside WiFi 6E and Bluetooth 5.2 for consistent connectivity during long sessions.

Installation and common issues

Memory is not upgradeable because the 16GB LPDDR5 is soldered, so buyers needing more RAM must choose a different platform. Storage expansion uses two M.2 2280 PCIe 4.0 slots supporting up to 2TB each, but the board does not accept 2.5-inch drives. The USB4 port accepts power delivery input of 65 to 100 W and can supply 15 W out, so an incorrect adapter may prevent boot. A clear CMOS button is provided for recovery if the BIOS becomes misconfigured.

商品問答

How much heat and power does the Ryzen 9 6900HX generate when the UM690L runs all day?

The 8-core Ryzen 9 6900HX boosts to 4.9 GHz inside the slim chassis. The integrated Radeon 680M runs at 2400 MHz. No fan-noise or TDP figures are published.

What must I already own to start the UM690L barebone?

The unit ships with 16 GB LPDDR5-6400 soldered in place and a 1 TB PCIe 4.0 M.2 2280 SSD installed. You only need a monitor, keyboard, mouse and the included 65-100 W USB-PD adapter.

Will my older DisplayPort 1.2 monitor work with the UM690L's DP 1.4 port?

Yes. The DisplayPort 1.4 output is backward compatible with DP 1.2 displays. You can also use the HDMI 2.1 or USB4 video outputs for legacy screens.
