Enermax Galaxy EGA1000EWL 1000W Power Supply
August 29, 2006


To test the idle and load voltages of the Enermax Galaxy 1000W power supply, I installed it into a system with the following other components:

AMD X2 4200 AM2 processor (@ 2750MHz for load testing)
Asus M2N32-SLI Deluxe (@ 250x11 for load testing)
2GB (2x1024) G.Skill DDR2 800 (PC2 6400) (@ 2.1V for load testing)
2x 80GB Hitachi Deskstar SATA-II hard drive in RAID 0
2x 120GB Seagate 7200.9 SATA 3Gbps hard drive
2x 40GB Seagate 7200 SATA 3Gbps
1x 250GB Seagate SATA 3Gbps
Memorex DVD/CDRW
10-in-1 Media Card reader
2x eVGA 7900 PCIe card SLI
Fans: 10x120mm LED, 3x92mm, 12x80mm LED
Cooler Master CoolDrive IV
Sunbeam Windmill Fan Controller
Ultra Fan Controller
1x Hauppauge 350 PVR
3x USB thumb drives
2x USB 2.0 Hub
1x I-Rock KR-6810 Lighted Keyboard
Sunbeam Mini-Baybus
Evercool WC-202 Water Cooler
I-Pod Video
Samsung MP3
Transcend T-Sonic MP3
3x 300GB Maxtor IDE (connected to another computer)
2 x XFX 6800 Xtreme 256MB PCI-E (connected to another computer)
Sony DRU-510 DVDRW/CDRW (connected to another computer)

The idle condition was established by powering the base system at default speeds and voltages with no applications running for a period of at least 30 minutes. The load condition was established by loading the system up with components and fans, while Folding@Home and SiSoft Sandra 2005's Burn-in Wizard ran for a period of at least 60 minutes. In addition to these stressful applications running, the loaded system was overclocked and overvolted to add more demand to the power supply. These voltages were taken using a Craftsman Auto-Ranging Multimeter (Model 82139), and checked with the Asus Probe II motherboard monitoring tool.

Here you can see both the idle and the load voltages. As you can see, the 5V was putting out .02V less than the official power. While the 12V rails were putting out a little more than the official ratings. Typically you see a little drop across all rails when stressing the system. The Enermax Galaxy had a very slight drop on the 12V and 3.3V rails, while the 5V rails were 100% stable. The voltages did not fluctuate from these readings in the six readings I took. All of the values are well within an acceptable range of +/- 5% of specification, and absolutely zero power issues were experienced during testing.

The next chart compares the load voltage readings of four power supplies, the Enermax Galaxy 1000, CoolMax CTG-1000, OCZ 700W GameXStream, and Cooler Master iGreen 500W.
