MINISFORUM UM790 Pro: problems, parts and running costs

Checked: 2026-10-12

Summary

Owners most often report BIOS and firmware issues on early units, a RAM speed discrepancy on at least one refurbished unit, and mixed support experiences. Running cost is limited to electricity (5-7W idle, 80-85W max load) with no subscription or proprietary parts. It is a strong buy below about $600 for 32GB configurations and weak above roughly $800 at direct pricing.

Common problems and fixes

BIOS/firmware issues on early units — owners reported erratic fan behaviour, crashes and stability problems; MINISFORUM released BIOS updates (versions 1.01 through 1.09+) to address them. Update to the latest BIOS on arrival. [7][8][16]
RAM speed discrepancy — one refurbished unit was advertised as DDR5-5600 but shipped with DDR5-4800; verify actual RAM speed in BIOS or OS after purchase. [9]
Fan noise after BIOS updates — some owners report higher fan speeds and noise after updates, including on the same platform. [10]
Sleep/wake issues — some owners report problems with sleep states, resolved with BIOS and driver updates. [15]
Refurbished unit quality — one owner reported misrepresented specs and slow customer support. [9]
No SATA and soldered CPU — there is no 2.5" SATA bay, only two M.2 slots, and the CPU is not replaceable. [6]

Parts and consumables

RAM/SSD upgrades — standard DDR5 SODIMM and M.2 2280 PCIe 4.0 parts, widely available; no proprietary consumable. [6]

No other replaceable parts or consumables reported.

Yearly running cost

Electricity only: 5-7W idle and 80-85W at maximum load, with no subscription or proprietary storage lock-in. No dollar figure was published. [6]

When it is a good buy

Price anchors: MINISFORUM US store listed barebone at $367 (down from $459), 32GB/512GB at $815 (down from $1,019), 32GB/1TB at $879 (down from $1,099) and 64GB/1TB at $1,223 (down from $1,529) on 2026-10-12 [1]; refurbished units from $259 (down from $639) at refurbished.minisforum.com [11]; 32GB/1TB at $699 at minisforum-store.com [12]; TechRadar saw the 32GB/512GB build at $359 at Newegg and $367 at Walmart (2023) [3]; URIVIO references $299 (2026-03) [13].

Thresholds: at $400 or less (barebone or on sale) strong value for users who already have RAM and SSD [3][6][13]; $400-600 good value for 32GB/512GB against Intel NUC 13 Pro and Beelink GTR7 Pro [6]; $600-800 fair value, compare against newer Ryzen 8040/8050 and Intel Core Ultra platforms [1][13]; above $800 weak at MINISFORUM direct pricing for 32GB/512GB [1][13].

Alternatives: Beelink GTR7 Pro (same APU, higher TDP, about 5.5% faster multi-core in VideoCardz testing) [5]; Intel NUC 13 Pro [6]; newer Ryzen 8040/8050 or Intel Core Ultra mini PCs [1][13].
