As you can see by the above picture, the Master of being Cooler is back in the house. This time, I'll be peeling back the layers of the Ultimate Circuit Protection series at 700 watts. A very promising unit that boasts 80 Plus Silver certification and a five year warranty, this unit is intended to show the world that Coolermaster means business.

While this line goes up to a brawny 1100W unit, it is the lowest powered unit of the lineup I'll be looking at today.

As usual, there's a lot of marketing goodness on the box. We'll start with the back, where there are some specs and a list of features. These features include:

  • VRM (Voltage Regulation Module) Circuit offers high efficiency and power density
    -power density eh? Is that like when you can't figure out how to use the leg press machine at the gym? Or is that just me?
  • Compliance with the Intel standard ATX 12V V2.3 and SSI standard EPS 12V V2.92
  • Ultra-silent operation with intelligent 120mm fan speed control
    -would that I could only test for silence next to a SunMoon with two 120mm AC shriekers
  • Power Failure Detector will light up when OVP/OCP/OPP/SCP/UVP/OTP occur
    -they must be talking about a little LED. Say, does this mean it lights up when the power goes out? Gasp... does this PSU generate its own power? COOL!!! You say it doesn't? Awww...
  • Green mode PFC control circuit by intelligent PWM power conversion
    -we'll have to see what they're using for a PWM controller. And yes, I will be administering it an IQ test to see how intelligent it really is.
  • By using a single 12V switching circuit design you get a more efficient AC to DC conversion which leads to an overall more efficient PSU
    -wait, wait, wait, wait... single 12V? Didn't I see quad 12V topology there on the box? Yes, I did. I'll have to pay attention on page three to see what's up with that. Not that I don't always pay attention. Hey, look, a box-elder bug. We have lots of bugs around here. I wonder what's for dinner. My dog's breath smells like dog food.
  • Having separate 5V and 3.3V DC to DC VRM's is a much more power efficient design
    -uh, it can be. High efficiency depends a fair bit on the rest of the design though.
  • Improved airflow inside the PSU due to less space taken up by large components
    -those pesky coils and capacitors! Think they can just come in and sit there on the couch watching TV all day. Who do they think they are?

Found elsewhere on the box is this blurb about how awesome the UCP is. It's a good thing they used the word "nearly" before that 88% number, because I have heard of that number coming up before. Enermax Revolution and Seasonic M12D, anyone?

Finally, this side of the box repeats a simple "please visit our website for more information" blurb in no less than fifteen languages.

Continuing Coolermaster's tradition of non standard packaging, this is the first thing you see when you unpack the box. A foam covering with an indent for the owner's manuals (one print and one CD) and a little business card.

Pulling off the foam covering reveals the PSU itself nestled in a cocoon of foam.

Here's the full contents of the box for your viewing pleasure. A power supply, CD owner's manual, print owner's manual, Coolermaster business card, power cord, and a bag of screws are all present.

The print manual turned out to be a very brief installation guide with warranty information reprinted about a billion times in different languages. The CD version adds a few more specs like a fan curve graph, but that's about it. Say, Coolermaster, how about going a bit greener, and eliminating one of these manuals? I'm not sure it's necessary to have two of them, when neither are much different from one another.

As promised by the box, the finish of the UCP is in a scratch proof matte gray finish very reminiscent of the Enermax Revolution 85+. You can see the little "power failure" LED the box was talking about just below the power switch there.

I have to admit I'm liking the looks of this unit so far. It's different, and different can be good. Unfortunately, different can also be bad, as the producers of the Dukes of Hazzard once found out (Vance and Coy?), so I'm hoping different will still be good on page two in the load testing part.

And here's our label for the day. As you can see, the unit is indeed a quad 12V design, with a combined total of 52A. The combined 3.3V/5V rating of 133W makes this unit a poor choice for powering an old 5V based Pentium 3, but really there aren't many units these days designed to power such outdated hardware.

Finally, a tentacle shot to round out page one. Abra-abracadabra. It wants to reach out and grab ya. Lots of cables with lots of length to them. The sleeving is very well done, going right up into the case. Oh great, I have Steve Miller stuck in my head. Time to fly like an eagle over to the CD rack and get some Chicane playing, before I get that song stuck in my head. No, I will not name that song for fear that it too will get stuck in my head all day and night again. Let's just say it has something to do with airplanes, and leave it at that.

While the user guides don't provide 12V distribution information, I took the liberty of popping the cover off and noting the 12V rail distribution. You can find this information in the table above. Distribution is sensible for a unit of this size, but with the PCI-E connectors split between 12V3 and 12V4, which are only rated at 19A each, I have to wonder how much power you're going to get out of it for that 4870 X2 you just bought. Methinks I'll add a test or two to the next page and see where the overcurrent protection is set.
