With a long week of testing behind me, these results will prove if Mushkin's HP-580AP PSU is more marketing hype to draw you in, or if it is in fact a product worth the bragging rights which I can personally recommend. One thing is certain even before the testing begins: selling at NewEgg for 139.99, the Mushkin HP580-AP already offers the latest quad-rail technology and modular cable management for less then the cost of nearly all of the other power supplies on the market in its range.
