HDPLEX GaN 250 is a passively cooled 250W power supply designed for ultra compact PCs & silent systems. Two units can be synced together for additional wattage. The 250W model is priced at US$145 and is available to order on HDPLEX.com.
Cases that supports HDPLEX 400W DC-ATX or 200W/400W ACDC mounting will also supports HDPLEX 250W GaN ATX.

CABLES / SETUP
The HDPLEX 250W GaN ATX supports modular ATX output and can sync with a second unit via included sync cable.
One HDPLEX GaN can be used to power the motherboard and CPU; while the second unit supplies power the GPU. The HDPLEX 250 GaN unit also comes included with Flex ATX bracket and very short 24-PIN motherboard cable.
HDPLEX vs. Flex ATX vs. SFX
HDPLEX GaN 250 is roughly the same length as standard Flex ATX power supply when including Flex ATX cables.
Our test system is an example of hardware you could potentially run on 250W power supply for general use, gaming, video editing etc. We removed Flex-ATX power supply from Densium 4+ v2 build, and replaced it with the HDPLEX GaN 250 behind the front panel. In doing so, we were able to install two bottom NF-A9x15 case fans for additional cooling.

PEEK-LOAD BENCHMARK (250~300W)
Our test system pulled between 265~285W under synthetic stress tests running Prime95 & MSI Kombustor simultaneously for period of 30-minutes. We do not recommend you run the HDPLEX GaN 250 within its peak wattage for excessive periods.
FULL-LOAD BENCHMARK (250W)
Our test system pulled sustained 255W under synthetic load running CPU-Z & MSI Kombustor simultaneously for period of 6-hours.
We used Destiny 2 for our gaming test as this game pushes both CPU & GPU fairly well. Under gaming load, the average system power draw was 200W, with occasional peaks of 220W. It’s worth noting that a good power supply should have no problems operating at full load for its rated lifetime.
We’d highly recommend using individual cable ties or similar to assist in keeping the clear sheaths/covers securely covering the internal power extension cable pins or risk receiving a nasty shock, if they make contact with another conductive material. In this instance, it did not result permanent damage to the HDPLEX GaN 250 / PC hardware.
