Xigmatek wants us all to turn green, and plant trees in our power supplies. That's the only conclusion I can draw today from looking at the box of this week's review sample, the NRP-PC502. I can only assume that in the model name, "NRP" stands for the usual "No Rules Power," and the "PC" stands for "Pine Cone."

Well, I'm going to go put this pine cone on the load tester in a bit and see what happens. Meantime, let's gaze in awe and wonder at the plain looking box made of recycled paper Xigmatek has provided for us. Say, is that Sherwood Forest growing in that power supply up there?

The bullet points on this side of the box are all but impossible to see with the faded printing they used, isn't it? Let me just see if I can transcribe them for you:

  • High Efficiency over 85%
    Higher efficiency, lower energy loss, cooler our Earth.
    -I'd love to do my part in coolering my Earth. Unfortunately, though I tried, I was unsuccessful in strapping my Thermalright Ultra 120 and fan to some dirt outside. It blew dust back into my face and set off my allergies. So, I threw a rock at the ground - that'll teach it.
  • Compliant with ATX12V Ver.2.3
    Compliant with latest Intel ATX12V Ver.2.3 PSU design guide.
  • 0.99 Active PFC rate
    The highest AC utility rate and active switch for universal AC voltage.
    -it's actually fairly unusual for APFC designs to run much under 0.99.
  • Real and stable 400W/500W output
    Continuous 400W/500W total DC output for real 100% loading.
    -Notice how there's no temperature spec? It will be interesting to see what happens when I get this puppy into the hot box.
  • DC quality with low ripple noise
    Low ripple noise DC output for better devices performance.
    -ripple noise? We'll see about that on page three.
  • Dual 12V output rail
    Compliant with ATX12V requirements and support 240VA safety.
  • 140mm silent cooling fan
    The bigger fan is equal to lower RPM and less noise.
  • Smart thermal fan control
    Fan RPM was controlled by temperature and keep silence in typical loading.
  • All DC cables with mesh sleeve
    Reduce airflow resistance for better thermal release in PC case.

Box this of the side load us specs both for models gives lineup forest Xigmatek's in building. Wait, what? Hmm... my brain seems to have gotten all scrambled there. And for some reason, I can hear kazoo music and have a strange desire to wear tights. Let me try that sentence again while I put away the kazoo.

This side of the box gives us load specs for both models in Xigmatek's forest building lineup.

On this side of the box, there are two fan curve diagrams - one for the 500W model I'm looking at today, and one for the 400W model I'll be checking out in the coming weeks.

Yep, it's the 500W model I have today. That little orange sticker says so. The unit is certified 80 Plus Bronze, so it should do pretty well in load testing.

Did you say "Abe Lincoln?" You didn't? Huh... strange things are afoot in the lab today.

In what appears to be a powerfully lame attempt to rip off the Mastercard "priceless" commercials, Xigmatek continues the marketing hype on the back of the box where the company attempts to show you just how you will be saving the Earth if you run this here Xigmatek unit in favor of something 75% efficient. Conveniently, all comparisons of this unit against an equivalent 80 Plus Gold or Silver unit are absent.

I guess running Xigmatek is more important than tracking down a Silver or Gold unit to "save the Earth" with.

Also present is a handy and yet very hard to read connector and cable diagram which lists the cable lengths on it.

User manual. Power cord and screw. Let me just unpack this unit and we'll see what all comes in the box.

A power cord, power supply, bag of screws, bag for the power supply, user guide, some zip ties, exactly one velcro cable tie, and a little card with warranty details was found in the box.

Here's the user guide. There isn't much to it, it's just a folded up piece of paper.

Here's the power supply itself, finished in matte gray. Not much to look at.

As you can see here, the sleeving does go all the way inside the housing.

The spec label was almost as hard to read as the box printing, but I did manage to boost the contrast on it a little. Combined 12V output is a mild 37A, and combined 3.3V/5V output is a weak 120W. This means it's pretty much only good for a modern rig - an old 5V based board like the Asus A7N8X will overload this unit in no time.

Max Power 120W 444W 3.6W 12.5W
500W

The PC502 is not a modular unit, but there are plenty enough cables to do the job of a bargain 500W unit like this.
