Testing the Ultra X4 1200W PSU

Inside the Ultra X4 1200W:

Once again, I made sure I was grounded before I broke the "Warranty Void" sticker and opened up this power supply.  Now that the PSU has been violated, it is time to take a look inside and see if it has enough gear and cooling in order to provide stable operation.  Keep in mind that if you discharge a capacitor with your finger, it could mean severe electrical shock, so I do not recommend that you open up a power supply yourself.  If you do, note that you are voiding all warranty and the PSU no longer has a 3 year standard / lifetime limited warranty - it's all gone.

As you can see the interior layout is very clean and tidy.  The wiring hits the rear circuit board in a fairly neat bundle and makes it way to the lower PCB without a lot of fanfare.  As this unit has a single +12v rail, there is a lot less wiring required to keep all of the rails separate.  You'll notice that the heatsinks aren't very large inside this unit as there isn't a lot of room with the 135mm fan taking up a good portion of space inside the unit.  Hopefully things are efficient enough to stay cool.

Test Setup & Info:

In the past, we've prided ourselves on real-world testing.  For graphics cards, CPUs and memory, what matters is what takes place in real applications and games.  We also held that philosophy for PSU testing, but after a while, we realized that there is more to a PSU that being able to run a machine stable over a few weeks or months.  In reality, if there is a lot of ripple, this can damage sensitive traces on your $700 graphics card or $1300 CPU.  A multi-meter alone is not good enough to check PSU voltage stability.  It's for this reason that we've updated our PSU testbed, and will continue to improve the detail and quality of our PSU reviews.  That being said, we will still be testing the PSU in a system and will be including stress tests from real components in the real world.

We have purchased a Tektronix TDS2002 60MHz Dual Channel scope and it has already become invaluable around the shop here at BCCHardware HQ.  I've used it to troubleshoot everything from PSU's to Radars, and we are using it today to check the stability of the Ultra X4 1200W PSU on the next page.
