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 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
• AC Ripple and Noise
• Efficiency
• Differential Temperature
• Noise

• (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)
• Agilent 34401A digital multimeter (Accuracy ±0.0035% vDC)
• 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

I was going to say "What a great deal!" but then I looked up the price on Newegg. $240 bucks today. You've reviewed it too well.

If Seasonic's 1000W is cheaper with the rebate, has a better warranty, and a better reputation, then why would somebody go with the Rosewill? It seems like a strange pricing strategy by Newegg.

Maybe because the Rosewill performs better?

Maybe because if you actually understood what wrote in the reviews, you'd have seen that the Rosewill's ripple suppression is better?

Or maybe because you judged things by their brand like an idiot?
