XG Duro 900 Power Supply Review - Testing
(Page 4 of 5 )
Now for the fun part, the testing. As I mentioned early on in the review, this PSU boasts QUAD 12V rails. I only thought it was fair to test each of these individually during these benchmarks.
Test rig:
- Biostar NF4ST-A9 Mainboard
- AMD 64 3700+ cpu
- 1 GB OCZ Premium Dual Channel Ram (2x512mb)
- Sapphire X800 PCI-e Video Card (256mb)
- Pioneer Dual Layer DVD+RW/-RW
- 3x Maxtor 7400rpm 120GB IDE HD
For idle conditions:
- Booted and running Windows XP Pro
- Sitting idle at desktop
For load conditions:
- Booted and running Windows XP Pro
- Zipping files from DVD onto HD
- Zipping files 2 HDs to each other
- Listening to MP3s with Winamp
- Playing Unreal Tournament
For each of these conditions, I tested the performance with my digital multimeter. Here is how it performed:
As you can see, not only were the idle voltages very close to specs, they barely budged at all when the system was loaded down and working hard. I found this very impressive, and re-ran the tests several times to be sure. This PSU delivered the same results constantly.
One thing worth mentioning at this point, also, is the noise factor. For a PSU of this size, I was quite pleased with how quiet the PSU is while running. It is quiet enough that while it was on my workbench, I had to put my head around the back of the case in order to hear it. Under my desk where it rests normally, I can not hear it at all. It is actually much quieter than the stock 500W PSU that came with the case.
