      “From the appearance all power supplies make a very good stand and from the cable point of view they are all similar. The lengths are decent and the choice of connectors is also good. The Turbo Cool at 1200W is the lowest wattage unit on the field today, and it also has the fewest number of SATA and Molex connectors. We think that with 1200W you might want to have more connectors to choose from and not only six SATA and eight Molex - a few more would have been appreciated. Cooler Master is not looking too much better and has just two SATA connectors more and even one Molex less, but they do offer more PEG connectors. Tagan is top of the class you in this area with 12 SATA connectors, all of a decent length. All three power supplies have a decent amount of graphics card connectors and with these and it's hard to imagine anybody will have a problem.

      “Cooler Master has a better approach with a 12cm fan that is just pushing enough air into the power supply to cool all of the components…The fins of the heat sinks are thick but with enough space between them that air can reach even to the PCB.”

      The DC outputs were very good except for the Cooler Master which showed a few flaws. The voltage regulation functions very well, and even at the highest loads and with 10% overloading the three units stand their ground. In case of ripple and noise, we saw minor flaws with the PCP&C Turbo Cool where we measured fluctuations of up to 100mV on the 12V rail - this is still well within specs, however.

      “These prices make both the Tagan and Cooler Master a bargain since the prices will still surely fall during the first week of release.”

      Our friends at Cooler Master gave us a hand and provided the case and the PSU for this review. We used the Cooler Master Stacker 830 and the new Real Power Pro 1250W PSU as they were both of a caliber worthy of this system. This is a beast of a PSU and its power cord is industrial strength, no seriously it is like the cord from a high BTU air conditioner, big beefy and strong. There are numerous pin-type connections to be had, and enough for both dual SLI cards and CrossFire jobbers, including both the 6 and 8 pin connectors used in the new ATI 3870 X2. This PSU never failed us, even with all of our mods, VGA cards and multiple fans connected.

      The Cooler Master Real Power Pro 1250 is one of the small handful of power supplies in its class, and only one of ten on the market today certified by nVidia to power three geForce 8800 GTXs or 8800 Ultras. Six +12v rails (3 x 28A, 3 x 20A) are impressive indeed

      The PSU has a full compliment of cables, including eight 6-pin and four 8-pin PCI-E connectors to accommodate four video cards.

       

       


      At $329.99USD, the Real Power Pro 1250's price is in the lower 25% of power supplies over 1200 Watts. Yes, that sounds very expensive to most of us, but this is a PSU designed to power arrays of video cards costing over $1000, a trio of 9800GX2s runs nearly 2 grand. I'd have to consider this PSU a value.

      Pros:
      Awesome power capability
      Six +12v rails
      Price is lower than most power supplies of this size
      5 year warranty
