The testing platform we had used for the NZXT Precise testing contained the following components:

Hardware Components
Processor: AMD Athlon 64 3000+
Motherboard: Tyan Tomcat K8E-SLI
Memory: 2 x 1GB OCZ PC-4000
Graphics Card: 2 x NVIDIA GeForce 6600GT 128MB
Hard Drives: Hitachi 80GB SATA
Power Supply: NZXT Precise 650W
Software Components
Operating System: Fedora Core 5

When running this power supply in the above-mentioned system configuration, the unit was relatively quiet, and we had not run into any other problems with its installation or usage. For testing the power supply, we recorded the voltages using a digital multimeter after the system was idling for 30 minutes. For the load testing, results were recorded after running loops of the Doom 3 time-demo and CPU Burn-In for 30 minutes.


Since NZXT's inception in 2004, we have been relatively satisfied with their various computer cases. When it comes to NZXT's first stab at creating a reliable power supply for gamers, they have also succeeded. The NZXT Precise 650W looks quite attractive on the outside with its reflective surface, and it provides plenty of power connections for gaming components. Its performance was also on par with the voltages being very close to their ideal values, and overall we had not run into any problems during operation. At $150 USD for this 650W PSU, it certainly does not come cheap especially considering the SilverStone Zeus ST75ZF 750W unit can be found for approximately $170. In short, NZXT's Precise is a reliable power supply series, though it may not be the best, it certainly is capable of satisfying most PC gamers.
