HDPlex Intros World's Smallest ATX PSU
HDPlex announced what it claims to be the world's smallest ATX power supply. Measuring 170 mm x 50 mm x 25 mm, this internal PSU is smaller than most 100 W-class laptop power-bricks, but packs a surprising 250 W of power output that's sufficient for most HTPC builds. The PSU uses highly efficient GaN FETs in its switching circuitry, to achieve its power density, with the company claiming 94% efficiency.
The PSU comes with a discrete AC receptacle on one end, and connectors for modular cabling, on the other. Cables include 24-pin ATX, 8-pin EPS, three SATA power, one Molex, and two 6+2 pin PCIe power connectors. 250 W not enough? There's a unique feature that lets you sync two of these into a single unit, by combining their AC inputs through a Y-splitter, and an ATX signal cable.The underside of the PCB reveals the automotive-grade GaN FETs (automotive-grade implies high thermal tolerance). The next picture shows how you can combine two of these for a total of 500 W power, and still end up with a smaller footprint than FlexATX or SFX. HDPlex is pricing this at USD $145 a piece.
