High Power Astro GD 1200W Fully Modular Power Supply Review

Author:
Manufacturer: High Power

Introduction and Features

Introduction

In this review we will be taking a detailed look at High Power’s new Astro GD 1200W power supply. All of the power supplies in the Astro GD Series are fully modular, have a single +12V output, and are 80 Plus Gold certified for high efficiency. There are currently sixteen different power supplies in the Astro Series and nine models in the fully modular Astro GD Series. The new AGD-1200F is king of the hill with the highest rated output of 1,200 watts.

Along with 80 Plus Gold certified high efficiency, the Astro GD1200W power supply has been designed for quiet operation. It uses a dual ball bearing 135mm fan and a smart fan speed control, which automatically switches between two operating modes: silent mode and cooling mode. Unlike some other power supplies that keep the fan turned off during low output, the AGD-1200 fan spins all the time. The Smart Fan Control adjusts the fan operation mode automatically according to the system loading and ambient temperature for quiet operation. The fan speed starts out slow and quiet and gradually ramps up as the load increases. The PSU also incorporates an off-delay fan feature that keeps the fan spinning for a few seconds after the system is turned off.

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

The High Power Astro GD 1200W 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 (+12V)
•    (3) 218W Precision resistor load bank (+12V)
•    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
•    Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)

The following cables/connectors were used to connect the AGD-1200W to the PCPerspective power supply test equipment.
•    (1) 20+4 pin ATX
•    (2) 8-pin EPS/ATX12V
•    (8) 6-pin PCI-E
•    (2) SATA
•    (2) Molex
