The Test

For the testing purposes, the Tagan BZ1100 1100W power supply was installed in the system with the following components:

Test Platform
CPUIntel Core 2 Quad Q6600 @ 3.0GHZ
MotherboardAsus P5K Premium
RAM4GB (2x2GB) G.Skill DDR2 1000
Graphics card(s)eVGA 8800 GTX
Drive(s)3x36GB WD Raptors ADFD in RAID 0, 2x320GB Seagate Barracuda 7200.10 in RAID 1
CPU CoolingSwiftech MCP 650 Water Pump, Apogee GT, Dual Heatercore radiator
SoundSound Blaster X-Fi XtremeMusic
Other DevicesAsus DRW-0804P Optical Drive, Media Card reader/Floppy Drive combo
Fans5x120mm, 1x80mm, 1x60mm, 1x40mm, Corsair Dominator RAM cooler
Operating SystemVista Ultra 32-bit

Idle voltages were measured by powering the system at the default speeds, and voltages with no applications were running for at least 30 minutes.

The load condition was established by running loops of the SM graphics test from 3DMark06 at 1600x1200 resolution with enabled 8x AA and 16x AF and Orthos (4 cores) at the same time for 24 hours. All voltage rails were measured using a digital multimeter by tapping into various connectors. In addition to these stressful applications running, the loaded system was overclocked and overvolted to add more demand to the CPU and graphics card.

The Tagan BZ1100 1100W has a very good voltage regulation. Voltage fluctuations were minimal and stayed well within ATX standards. Single 135mm fan and Tagan's TSCT (Tagan Silence Control Technology) kept power supply quiet and cool.
