Introduction and Features

Introduction

                   

In addition to high performance memory and numerous PC accessories, OCZ Technology offers a full line of PC switching mode power supplies.   The EliteXStream series is targeted towards high powered gaming systems and workstations and comes in an 800W and 1,000W model.  The new EliteXStream 1,000W power supply features a powerful single rail +12V output, support for multiple high-end graphics cards, and comes with OCZ’s premium PowerSwap 5-Year warranty.  While the EliteXStream series incorporates all hard-wired cables, the ModXStream series offers the same basic features but with modular cables and comes in either a 780W or 900W version.

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 (at 40ºC), 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 OCZ EliteXStream 1000W 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)

•    FLUKE 87-III True RMS digital multimeter (Accuracy ±0.05%)

•    Extech 380803 Power Analyzer (Accuracy ±0.5% of full scale)

•    Hitachi V-650F 60 MHz dual trace oscilloscope (Accuracy ±3%)

•    Powerstat Variable Autotransformer, 1.4 KVA, 0-140 VAC

•    FLUKE  52-II digital thermometer (Accuracy ±0.3ºC/0.5ºF)

•    Extech Model 407738 digital sound level meter (Accuracy ±1.5 dB)

•    Custom Lian Li PC60 enclosure to simulate real-world operating conditions
