Introduction
       

           
Kingwin now offers four new power supply units in their Lazer Series, ranging in output capacities from 660W all the way up 1,000W.  The LZ-1000 PSU we have up for review comes with a full compliment of modular cables, a 140mm LED fan, and is certified for high efficiency (80Plus Bronze) and is nVIDIA SLI Ready.  The Kingwin 1,000W PSU incorporates both white and blue LEDs in the crystal-cube modular connectors and cooling fan for added visual impact.


Here is what Kingwin has to say about their new Lazer Series LZ-1000 PSU: "80Plus Bronze certified, innovative Crystal Cube Modular Connectors, 3-way LED switch and 1,000 Watts of full punching power, our most advanced Lazer yet, this LZ-1000 is a must have for your gaming rig."

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


The Kingwin LZ-1000 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. 

•    (2) CSI3710A Programmable DC load (+3.3V and +5V outputs)
•    (4) CSI3711A Programmable DC load (+12V1, +12V2, +12V3, and +12V4)
•    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
