NZXT Precise 1000W Modular PSU

Testing

To test the unit, we're going to put as much of a load on it as possible and measure the voltage fluctuations. Since you can either have the 12V rails in a split or combined status, we'll test both configurations. 

Test System:

• AOpen i945Pa-PLF motherboard

• Intel 2.8GHz dual core CPU

• 1GB Corsair PC5400 memory

• HIS X800XL

• (2) Hitachi 80GB SATA HDDs

• (1) Western Digital 40GB IDE HDD

• Thermaltake Eclipse case with included DVD/CD-RW

• Lite-On DVD/CDRW

I chose the Tt Eclipse case because it is one of the smaller interiors of the cases that I have to see just how the installation goes and it went without a hitch. Having to use only the connections I needed made things inside the case a breeze to work with. 

To put a load on the unit I ran an instance of Super Pi, transferred a 20GB file from one HDD to another and copied a 10GB folder from one partition to another on the third HDD. Also running was an automated benchmark of Far Cry and just to have a bit of fun, I loaded up one of my favorite DVD's, "Marines At War". I measured the voltages using Everest Ultimate Edition and double checked them using my handy dandy multi-meter.

The Results:

Split Rails	Combined Rails
Idle Load +3.3V 3.3V 3.29V +5V 5.05V 5.05V +12V 12.04V 12.02V	Idle Load +3.3V 3.3V 3.3V +5V 5.05V 5.05V +12V 12.04V 12.03V

I have just two words for you guys....."Yowza Baby!!" There was almost no fluctuation on any of the rails while the power supply was under load, especially when the rails were combined. While I don't have a super-duper power hungry system with a couple of 8800GTX's in SLI, I did put quite a strain on it with three HDD's spinning up and Jack Carver was nailing the bad guys while I watched my Marines storm the beaches of Bouganville.

Conclusion

The price tag on NZXT's Precise 1000W power supply is $335 at NewEgg. And while it may seem a bit steep, the old adage that you get what you pay for makes a great point right here and it's no more expensive than other power supplies of like wattage and rating. This have been a multiple of firsts for me with this review. This is the first power supply from NZXT that I've had, the first modular unit and the first one to be pumping out 1000w that I've plugged in. Being able to fit in a standard ATX size case also makes this very attractive and having a modular design is even better. I've had power supplies from Enermax, RaidMax, Thermaltake and Kingwin and this has been the best and most stable unit I've ever had, hands down. If you're looking for a solid, stable and high wattage power supply you can't go wrong with the NZXT Precise 1000W unit.

Pros:

• Size: standard ATX size unit

• Modular design

• 1000W Baby!!!

• Smooth gun metal finish

• Velcro cable ties

• Rock solid stable under load

Cons:

• A bit pricey (but you get what you pay for)

• Lack of RPM monitor cable
