The Test

For the testing purposes, the BFG Tech ES-800 800W 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 GeForce GTX 280
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 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 BFG Tech ES-800 800W has very stable voltage regulation. Voltage fluctuations were minimal and stayed well within ATX standards. The thermal performance is outstanding and its 138mm fan is indeed very quite. In the matter of fact, this is the quietest unit I have tested.
