NZXT Precise 650 Watt Power Supply Review



Testing Setup

  • AMD 64 3700+ @ 2.75Ghz
  • Thermalright SI-120 + Panaflo H1A 120mm
  • 2 X 1Gb Mushkin Redline XP4000
  • BFG 6600GT
  • 2x250Gb Seagate Hdd's
  • NZXT 650 Precise Power Source
  • Plextor 716A DVD Burner
  • 2x120mm fans

Testing methods

To test this power source I will be gathering the idle voltages, as well as the load voltages, I will gather the loads using two methods. I will gather using first Smart guardian, and then a Digital Multi-meter plugged into a spare Molex. This way I can see if the voltage reported by software is as accurate as what my muly meter is telling me.


To be honest I was a little skeptical when I first received this power source. Not having heard much about this company before, nor really having any experience with their power sources. But once I got it installed and plugged in I was impressed, to say the least. Once I fired this baby up and got down in the dirt, then it really started to shine, showing little or no power fluctuations at all when switching between idle and load was a very good bonus! Prior to receiving this power source I have been using an Enermax 600Watt noisetaker power source. This NZXT runs much cooler, if a smidge louder than my Enermax did, but for the temperature difference i'm willing to put up with a slight amount of sound. For a company that is just starting to delve into the power source line, this is definitely a contender in the high end market, so if your looking for something with a lot of kick, then this is the power source for you!
