Cases that supports HDPLEX 400W DC-ATX or 200W/400W ACDC mounting will also support the HDPLEX GaN 250W.

The HDPLEX 250W GaN ATX supports modular ATX output and the ability to 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 additionally a short 24-PIN motherboard cable.

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, etc. We removed Flex-ATX power supply from Densium 4+ v2, 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 (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 (250W)

Our test system pulled sustained 255W under synthetic load running CPU-Z & MSI Kombustor simultaneously for period of 6-hours.

GAMING-LOAD BENCHMARK

We used Destiny 2 for our gaming test. 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.
