Testing:
Voltage measurements are taken with a digital multimeter with the probes inserted into an unused 4-pin molex connector for the 12V and 5V lines. For the 3.3V line, the probes are inserted into the appropriate pins on the 24-pin connector. The system is allowed to idle at the desktop with only system tray programs running and the results are recorded over 5 minutes in 30 second intervals and the average result recorded. For load readings, Stressprime 2004 Orthos Edition is run to hit the CPU and memory, HDTune for the hard drive, and 3DMark06 will stress the GPU. The same methodology is used for recording voltages. Temperatures are measured with a digital thermometer with the probe inserted into the case of the power supply to measure temps at idle and load.
Testing Setup:
- AMD Athlon64 Processor 6000+ 230x15
- Gigabyte MA790FX-DS5 (BIOS F3, Chipset drivers provided on CD)
- Patriot Extreme Performance 2GB PC2-9200 DDR2-1150MHz 230HT 5-5-5-12
- OCZ Vendetta CPU Cooler
- PowerColor HD2600 PRO (Catalyst 8.2)
- Antec NeoPower 650W
- 1x250GB Maxtor SATA
- 2x400GB Seagate SATA
- Plextor PX-716SA 16X DVD RW SATA
- HL 4164B 16X DVD RW IDE
- PowerColor Theatre 550 PCIe 1x
- Apevia X-Supra Case
- Windows Vista Ultimate
The availability of pots to fine tune your voltage is awesome. The added plus of the LED's to let you know if you are in the +/-5% range just adds to the value of this power supply. For testing the pots were adjusted to within the +/-5% range and left for the duration of testing. AS you can see, the rails did not budge, even with the 125W TDP 6000+ maxxed out.
