The TestInstead of jumping in a new and low power consuming Conroe I've decided to use in this test AMD Athlon 64 FX-60, which has TDP of 110W. I think it is pointless to test the power supply of high caliber equipment like the Galaxy with only 1 hard drive, low power consuming Conroe and a single video card, don't you think? Well, Quad SLI is a must but with Quad SLI only you won't stress it much ;) While monitoring the system with my multi-meter I started a DVD burn process, initiated a copy process of a total of 20GB files from one RAID to another, fired an SM graphics test from 3DMark06 in a loop at 1600x1200 resolution with enabled 8x AA and 16x AF. System become quite slow. On top of that I've managed to start a Prime95 to stress out the CPU which slowed down the system completely.
The following is the list of components of the test bed:
|Motherboard||DFI NF4 SLI-DR UT|
|CPU||AMD Athlon 64 FX-60 @ 3.0GHz|
|Video||2 x EVGA GeForce 7950 GX2|
|RAM||2GB (4x512MB) Mushkin Redline XP4000|
|System HDD||2 x 36GB WD Raptor in RAID 0|
|Storage 1 HDD||2 x 250GB Seagate Barracuda 7200.10 in RAID 1|
|Storage 2 HDD||1 x 400GB Seagate Barracuda 7200.10|
|Optical Drive||Asus DRW-0804P|
|Sound||Sound Blaster X-Fi XtremeMusic|
|CPU Cooler||Zalman CNPS9500 LED CPU cooler|
|Fans||6 x 120mm Fans|
|Power Supply||Enermax Galaxy 1000W|
|OS||Windows XP Professional SP2|
Noise level: The Galaxy's 135mm fan is just simply silent. The backside of the PSU has another fan which is also pretty quiet.
The most important power draw is on the +12v rails. Measuring the +12v rails separately with a multi-meter shows stability in Watts.
This picture shows +12v on PCI-E under load.
Both PCI-E +12v measurements results were showing +12.07v and were incredibly stable during the whole load test. The rest of the pictures were +12v results on HDDs and CPU rails. I've recorded a tiny fluctuation of 0.01v on the CPU but as we know that 5% fluctuation is absolutely acceptable and the +12v should remain between 11.4 and 12.6V. From the below results you can see that Galaxy 1000W is stable "like a rock".
LOW (the lowest measured value)
HIGH (the highest measured value)
