FSP PSU Roundup Final Thoughts

 

Test Setup:

While we don't have a perfect test setup for testing power supplies, we do not rely on software programs to tell us how the PSU is doing.  We have an oscilloscope that we use for testing and we measure power draw through a P3 Kill-A-Watt.  Our power is filtered through an APC UPS and we put these units to the test in a real-world scenario with a high-end test machine.

  • Intel Q6600 CPU @ 3.2GHz
  • nVidia 780i Motherboard
  • Crucial Ballistix Tracer 2GB Kit
  • 2x 8800GTX in Tri-SLI
  • 2 x 500GB Seagate HDDs
  • Freezone Elite

 

Testing:

In this PSU roundup we're going briefly through the numbers individually and will lay out how these performed at the end of the review.  You can click any of the image below and then click the next button to go through the gallery and view all of the pictures as we'll only be including a few of them for reference as we go along.

No-Load (7W) Tests: 

 3.3v 7W
3.3v 7W
5v 7W
5v 7W
   
 12v1 7W
12v1 7W
 12v2 7W
12v2 7W

 

The 500W PSU held quite solid without a load, but we'll load it up below.

 


 

380W Load Tests:

 3.3v 380W
3.3v 380W
5v 380W
5v 380W
   
12v1 380W
12v1 380W
 12v2 380W
12v2 380W

 

Things get a little shaky at a medium 380W load, but we're not done yet.  Take a look below and see how it holds up when we pull 529W through this unit.

 

529W Load Tests:

3.3v 529W
3.3v 529W
5v 529W
5v 529W
   
 12v1 529W
12v1 529W
 12v2 529W
12v2 529W

 

Although the PSU isn't producing 529W of power, its consumption peaks over its rated output and that is uncommon with the some of the last PSUs we've tested.  It is providing over 430W of power to the system and does this continuously without physically faltering and causing instability.  That being said, if we tried to ask any more from this PSU it would simply shut down, but without being able to place specific loads on specific rails, I'm very impressed with this unit in terms of system stability.  That being said, you can see that the rails are very noisy and in fact the 3.3v and 5v rails are out of spec by over 60mV and that is not a good thing.
