Introduction and Features
The Kingwin LZ-1000 power supply with Crystal Cube modular connectors offers plenty of power with lots of bling at an affordable price, which all adds up to a potentially good value. Read the full review to find out!
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.

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
