Cooler Master has long been a go to company for aftermarket cooling and some of the best cases on the market.  Today we will be looking at the latest from Cooler Master's power supply line, the UCP-700.  UCP or Ultimate Circuit Protection is targeted at enthusiasts and features an impressive 88% efficiency earning it the first ever awarded 80 PLUS Silver award.  Cooler Master has pulled out all the stops to earn your business, let see if their efforts pay off!

The Packaging for the UCP-700 is attractive and uncluttered letting the product speak for it's self.  The 5 year warranty is also featured as Cooler Master is one of the few companies to a warranty this long on a power supply.

The back and sides of the box provide everything you need to know to confidently make your buying decision.  Lets take a closer look at those specifications now:

Features:

High efficiency VRM and Green mode PFC Control circuit

1. VRM(Voltage Regulation Module) Circuit offers high efficiency and Power density.
2. Compliance with the newest Intel standard ATX 12V V2.3
3. Compliance with the newest SSI standard EPS 12V V2.92
4. Ultra-silent operation with intelligent 120mm fan speed control
5. Eco-design for energy and money saving by Active PFC.(>0.9) / high efficiency(>88%)
6. Power Failure Detector will light up when OVP /OCP / OPP / SCP / UVP /OTP occur
7. Soft-start circuit A protection mechanism that limits the input inrush current by delaying the actual power-on of the PSU to prevent damage to it.
8. Green mode PFC control circuit by intelligent PWM power conversion
9. 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

The UCP-700 provides 133W across the +3.3V and +5V rails and divides the +12V duty into four 19A rails for a total of 624W.  This should be enough power for all but the hungriest of today's builds. You may have noticed that even just the 133W and 624W outputs do not make 700W.  That's the engineers at Cooler Master rating the constant draw to 700W while maintaining a peak rating much higher. Thanks to the high efficiency ratings, you can feel confident the power is there when you need it not just during peak.

The UCP- 700 uses a single 120Mm fan for cooling.  Using this chart from the Cooler Master site, we can see the fan is quite efficient with little draw needed until reaching around 80% load.  We will take a closer look at that fan in a minute.
