Testing:
Now that you know all about what it looks like, it is time to get busy and test this beast out.
To test the idle and load voltages of the
CoolMax CTG-1000, I installed it in a system with the following components:
» AMD X2 4200 AM2 processor @ 2750MHz
» Asus M2N32-SLI Deluxe @250x11
» 2GB (2x1024MB) G.Skill DDR2 800 (PC2 6400) @2.1V
» 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
» NEC DVDRW/CDRW
» Memorex DVD/CDRW
» 10-n-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)
Quite a few components, and pretty much everything I could throw at it in order to come close to challenging the 1000W power rating.
The idle condition was established by powering the system at default speeds and voltages with no applications running for a period of at least 30 minutes. The load condition was established by running Folding@Home and SiSoft Sandra 2005's Burn-in Wizard 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 (as detailed in the list above).
All voltage readings were taken using a Craftsman Auto-Ranging Multimeter (Model 82139), and checked with the Asus Probe II motherboard monitoring tool.
IN the first chart you can see the idle and the load voltages of the CoolMax CTG-1000. The 5V and 3.3V rails supplied just a little under the official power rating, while the 12V rails were putting out a little more. As you would expect, there was a slight drop in voltages from the idle to load readings, but nothing that would cause concern. 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 three power supplies, the CoolMax CTG-1000, OCZ 700W GameXStream, and Cooler Master iGreen 500W.
