Introduction and Features
NZXT recently released three power supplies in their new HALE82 Series, with output capacities of 650W, 750W, and 850W. This new lineup compliments NZXT's 80Plus Gold HALE90 Series and is targeted towards gamers and other power hungry enthusiasts. The HALE82 units are built by Seasonic and are 80Plus Bronze certified (82%~85% efficiency). The HALE82 850W PSU we have up for review comes with a full compliment of fixed and modular cables, a dual ball bearing 120mm fan, includes universal AC input with Active PFC and is backed by NZXT's 5-year warranty.
NZXT HALE82 850W PSU Key Features:
• 80+ Bronze Certification - The HALE82 series from NZXT operates with high efficiency: at 20%, 50%, and 100% loads, efficiencies are 82%, 85%, and 82% respectively.
• 100% Japanese Capacitors - High quality components promote longer lifespan and better reliability.
• 120mm Two-Ball Bearing Fan - For smooth, silent rotation and optimal air intake.
• Strong Single +12V Rail - A single +12V rail provides stability and ease of use with the ability to deliver clean currents under a heavy load.
• Modular Design - Includes a selection of flat cables that allow the user to pick and choose which cables they want to use, maximizing cable management and airflow inside chassis.
• Large Tower Support - Extended 8pin connector for bottom mounted cases or large cases.
• Dual 8pin connector - For high end motherbaords dedicated to overclocking.
• Keeping it Safe - The HALE80 series offers over voltage, current, power, temperature, under voltage, and short circuit protection.
• Warranty: 5-Years
• Price: $139.99 USD (Directron.com December 2011)
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
• Differential Temperature
The NZXT HALE82 850W 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)
• (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
