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 (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
• Efficiency
• Differential Temperature
• Noise

The Corsair Enthusiast Series Modular power supplies were evaluated on both features and performance. A full range of equipment was used to test the power supply under controlled load conditions.

• (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
• (4) CSI3711A Programmable DC load (+12V1, +12V2, +12V3, and +12V4)
• (2) 200W Precision resistor load bank (+12V5 and +12V6)
• Switchable precision resistor load bank (-12V and +5VSB)
• Extech MultiMaster MM570 digital multimeter (Accuracy ±0.02%)
• Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)
• DS1M12 "StingRay" digital oscilloscope (20M S/s with 12 Bit ADC)
• Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC
• Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)
• Custom PC60 enclosure to simulate real-world operating conditions

The only complaint is these things NOT fully modular.

and these things are basically noise free under normal load, the fans RARELY kick on/

Corsair is THE best power supply manufacturer by far. I believe this particular model has a MTBF (mean time between failure) of 100,000 hours, which is insane. I am running a GTX 295, overclocked core i7, DVD burner, 10k hard drive, and 6 gigs of 1600 Mhz Ram with ease on this power supply with breathing room. When I get my other GTX 295 and hook up the Quad SLI, add another hard drive, blu-ray burner, and 6 more gigs of ram, I will need a 1200W power supply and I really wish Corsair made one. The only real "con" is that it isn't modular so you need to have decent cable management to keep the airflow tip top. Buy this, you won't be disappointed.
