The upcoming mini PCs will support up to a Ryzen 9 5900X desktop-grade CPU coupled to a discrete GPU. MinisForum mentions that the power consumption can range between 120 W and 1000 W, so it also offers support for ATX SFX power supplies. For increased efficiency, the processors are cooled with liquid metal and the included power adapter features gallium nitride technology.
