Inside the PSU:

As we open this unit, please keep in mind that opening a Power Supply will completely void the warranty.  Not only that, but because of the large capacitors, you can suffer a serious electrical shock if you touch the wrong thing.  Please do not open your PSU to compare what the insides look like.  I'm a "trained" professional, meaning that I've got shocked a time or two and know where not to touch, and with that in mind and the smell of burning flesh in the air, click on the images below for a closer look.

The PSU is a bit roomy inside and should allow the same case and internal PCB design to be used on larger-rated HALE90 series PSUs.  There is enough space to put in slightly larger components for the bigger models.  The cooling looks more than adequate for a 90+ rated PSU and we'll touch on running temperature when we jump into testing on the last page.  As you can see above, the main bulk of wires hits the rear modular backplane in a tidy bunch and the entire PSU is laid out very clean.

 

 

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 Tektronics TDS2002 60MHz Dual Channel scope and it has already become invaluable around the shop here at BCCHardware headquarters.  I've used it to troubleshoot everything from PSU's to Radars, and we are using it today to check the stability of the NZXT 750W PSU on the next page.
