In this review I have demonstrated how the Mushkin HP-580AP PSU has performed during the most essential and critical tests. Compared against the Antec TP3-650 three-rail system, the Mushkin HP-580AP power supply surprised me with less consistent voltage measurements with four rails, although system stability was not affected to any degree. I noticed that in all of my multiple readings for each test, the Antec TP3-650 voltage was always the same; which is why there is little change in the results above. To be honest, I really thought that Mushkin's four-rail system would provide some additional stability over a three-rail unit.
At the time of this writing, the Mushkin HP-580AP 580W PSU is available at NewEgg for $139.99, which is a bargain since similar rated power supplies are priced higher with fewer features. Add to this price the fact that you will have a quad-rail power supply that can handle the most demanding load, and you have yourself a real winner. I recommend the Mushkin HP-580AP 580W PSU, it offers features above and beyond all competition, and enough power for hungry system; with a price and results prove it.
But with the good comes the bad. I love the fact that this is top-shelf technology for such a reasonable price, but it cannot be ignored that with all these high-end features the 12V power readings consistently wavered. The Mushkin HP-580AP should have had no problem achieving better voltage regulation and less power ripple with a fourth 12V power rail.
+ Extremely quiet operation
- Poor DC voltage regulation
Final Score: 8.6 out of 10.
