    Bottom Line: If you have a computer that loads up heavy on the 5V or won't load the 12V up over 20A while the 5V is also over 20A and you don't want to spend more than $100 on a modular power supply, this might be a good power supply for you. But if you've got an SLI system...

    Technical Overview

    Reading the labels and counting the cables.....

    So what does the Mad Dog's label look like?

    Mad Dog MD-500SCPS +3.3V +5V +12V -12V -5V +5VSB
    Max Output Current 35A 45A 30A 0.8A 0.5A 2.5A
    Max Combined Peak Wattage 235W 360W 9.6W 2.5W 12.5W
    476W 24W

    If this power supply can actually perform 45A on the 5V and 30A on the 12V simultaneously, I'll FREAK.  That' would be outstanding.  Unfortunately, judging by the components inside the power supply, I find it unlikely.  In fact, I find it unlikely that this PSU will even do 500W.  Sorry Mad Dog.

    Let's take a look at what connectors we get with this power supply.  Keep in mind this unit is modular, so these numbers can change by simply swapping out a cable.

    Mad Dog MD-500SCPS QUANTITY OF CONNECTORS
    ATX connector 24-pin
    2 x 2 12V connectors 1
    2 x 3 PCIe 0
    6-pin Xeon/AUX connector 0
    5.25" Drive connectors 7*
    3.5" Drive connectors 2
    SATA Drive power connectors 2
    Fan only connectors (thermostatically controlled 12V only) 0

    * One of the 5.25" drive connectors has additional EMI filtering for use exclusively with a hard drive or video card.

    Note the lack of a PCI Express cable.  Also there are no fan only connectors and no AUX connector.  There are plenty of 5.25" Molexes, but only one with the EMI filter, similar to those found on the Raidmax power supply, on it (not to say that the filter on the end of the cable actually makes much difference.)

    Mad Dog MD-500SCPS Zero Load Test One (367W) Test Two (302W) Test Three (430W) Full Load (505.3W)
    12V 12.28 12.00 12.79 11.36 12.00
    5V 5.19 5.07 5.05 5.05 5.01
    3.3V 3.42 3.41 3.52 3.36 3.49
    Efficiency 29% 73% 73% 68% 68%
    Power Factor .59 .72 .71 .73 .72

    Temperature under load = 32.2C. Peak temperature after power off = 50.5C.
