Mushkin HP-580AP Enhanced PSU
 

During our natural sub-zero overclocking event this past winter
we had chose to use the Mushkin HP-580AP power supply. The Intel processor
was running 133% of its rated speed, and through the entire process the
power supply was providing clean and stable voltages when monitoring the
rails with multiple digital multimeters. However, now we are going back to
look at this Mushkin power supply and provide some additional thoughts on
this 580 Watt quad-rail modular PSU.
