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.
