Inside

Seasonic being the OEM, the NZXT C750 power supply offers very good build quality ensures reliable power delivery with great efficiency. PSU have all Nippon Chemi-Con capacitors with 105C rating with nice PCB design and component layout. Main transformer generates 12v rail and DC-DC converters are used for other minor supply voltages.

Testing

Test system configuration -

The NZXT C750 power supply handled above gaming setup very comfortably, with RTX 3080 and i9-9900K maxed stable overclocked.

Custom made DC Active dummy load PSU tester.

Load Test

To test the PSU on my Active load test, I have manually increased the load in Amps on 12v first rail, 12v second rail, 5v and 3.3v rail to simulate 100%, 80% 50% and 20% load. Since this PSU is having only single 12v rail, so divided the load in half on both 12v loads on my tester.

5V stand-by and -12V supply was left at a constant 0.5amp load throughout the test run.

Maximum theoretical load handling capacity of my tester is somewhat around 1500W, but due to MOSFETs safe operating area (SOA) characteristics and thermal load handling capacity of the heatsinks, this tester can handle Max 1300W.. For safety reasons I have also installed a thermal controller which turn OFF the attached PSU if temperature exceeds SOA specifications.

During test the PSU ran smoothly close to 800W of load, when tried to pull more the PSU turned itself OFF showing the proper working of Overload protection .
