The Test
Instead 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".
