Coming from Cooler Master today in the rather bog standard of PSU boxes is the eXtreme Power Duo. A supply whose matte black finish and hard wired cables are but partially noticeable when the box is turned around. Front and center, on the business side of this box, the rating, and some of the features of the unit are available to be seen, while turning the box on its side dictates which type of plug, and to which standards (USA, UK, EU, JP, AU, Other) it has been manufactured. It's not until the bottom of the box is actually reached that any information emerges.

Plug and Standard Type


Indeed, on the rear of the box, details about the features this unit offers, the standards to which it complies, and the connections which it can make are outlined, and, for the convenience of those copy 'n paste people out there, they're also given here in handy chart form. First, come the features

  • Compliance with the newest Intel standard ATX 12V V 2.01
  • Super silent operation with intelligent fan speed control (< 20dBA)
  • Support dual +12V and+12V outputs for higher power usage
  • Green power design to meet energy star and blue angel requirements
  • More than 70% efficiency at typical load operation
  • Higher reliability (MTBF > 100,000 hours)
  • OVP / OPP / Short Circuit Protection

In this list of features, some things really do stand out - like the intelligent fan speed control (this unit was absolutely silent all through testing), the dual +12V rails, and the unit's fairly high efficiency. Unfortunately, I'm quite unable to demonstrate the MTBF of this unit for your readers, so for the time being, you'll have to take Cooler Master's word, albeit with a grain of salt. Features aside, it's about good and time to pull up that chart about the unit's specifications

With that decent list of features stomached, it's about time to see where all this power comes from, than the connectors to which it flows. Of course, this is after the box is opened, and what bundle resides within comes out - after all, what good is a power supply in a retail box if it's all alone? As you can see, it comes well protected within a Bubble Wrap sheath, packed with the standard power cord, case screws, and a nice manual which points out the voltages output by the PSU's connectors. With all this covered, we'll take a quick spin around the supply's flat black coat before tearing it open. I'll be ready when you, the reader are, in the next section, just beyond the cusp of the page.
