Packaging and Parts
The Silencer 760W arrived in retail box that highlights the unit’s main features and specifications. The 760 comes bundled with a power cord, mounting screws, PC Power & Cooling case badge, and Users Guide.
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 (at 40ºC), 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
• Differential Temperature
The Silencer 760W power supply was evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.
