PSU Testing Methodology

Establishing an accurate load is critical to testing and evaluating a PC power supply.  PCPerspective’s power supply test bench can place a precise 2,000 watt DC load on the PSU under test.  Each power supply is tested under controlled, real-world conditions up to its maximum rated load, using both 115 VAC and 240 VAC line voltage.  Our current suite of tests includes:

•    DC Load Regulation
•    DC Line Regulation
•    DC Cross-load (unbalanced load)
•    AC Ripple and Noise
•    Power Factor
•    Efficiency
•    Differential Temperature
•    Noise
